Aquatic animals utilize water-borne "chemical signals" (chemical stimuli) to identify and orient toward potential food sources, to escape predators and locate mates. These specific chemical signals are recognized in spite of the chemical complexity of aquatic environments. Therefore, the chemical environment of aquatic animals is vitally important, both physiologically and behaviorally, to understand the status and role of animals in the aquatic environment. The function of specific chemical signals becomes even more significant in a managed biological system (i.e., aquaculture ponds or tanks) that is optimized for production of a single aquatic species (e.g., members of the Penaeus genus of the Class Crustacea) since these chemical signals regulate feeding behavior and possibly control reproduction. Because feeds are a significant expense in most aquaculture operations, the need to maximize feeding rates and reduce wasted feed, thereby lowering production costs and the possible lowering of bacterial/viral infections is paramount to economic success.
The importance of chemoattractants and/or feeding stimulants in improving both initial palatability and overall feeding rates as a means to reduce wasted feed is now fully recognized. The feed quality and environmental conditions (i.e., water quality and current patterns) have direct effects on the effectiveness of feed attractants and feed stimulants. For these reasons, food detection and feeding stimulation ultimately determine the commercial value of an aquatic feed.
A number of attempts at obtention of efficacious feeding stimulants for various aquatic species and for creation of appropriate testing apparatus having a high degree of efficiency for determining good stimulants and attractants for aquatic species are set forth in the literature. Thus, U.S. Pat. No. 4,250,835 issued Feb. 17, 1981 and U.S. Pat. No. 4,249,480 issued Feb. 10, 1981 disclose apparatus and methods for rearing shrimp through the larvae stage wherein the shrimp are subjected to controlled conditions and a common enclosure for the male and female adult shrimp is provided which permits uncontrolled access of the shrimp to one another and wherein the shrimp are maintained through a plurality of cycles of mating, spawning and hatching. The system disclosed provides filtration means for filtering the medium of the common enclosure and with collecting means for harvesting hatched shrimp at preselected times from the common enclosure medium as the medium moves into the filtration means. U.S. Pat. No. 4,828,829 of May 9, 1989 discloses a visual fish attractant that aids in the dispersion of traditional scent and taste attractants. The fish attractant compositions include one or more oils, such as mineral oil, cod liver oil, menhaden oil, herring oil, anise oil, salmon oil, as well as pigments, fragrances, fish scent, dispersed pigments, and light-reflective particles that act both as a visual attractant and as an aid to controlled dispersion of the oil and scent compositions.

Abstracts, Volume 115:113303n. The disclosure of Japanese Published Application 91/27231 does not detract from the patentability of the instant invention.
Nothing in the prior art, however, discloses the efficient process for attracting, inciting, stimulating and/or exciting members of the Penaeus genus of the Class Crustacea from or in a volume of water inhabited by said member(s) of the Penaeus genus of the Class Crustacea in or to a desired location or volume within a body of water by applying at least one of the specific materials found to be useful in our invention, to wit the "ASIE" substances found to be so useful in our invention. Furthermore, nothing in the prior art discloses feeding compositions containing such "ASIE" substances admixed with prior art feeding materials for such members of the Penaeus genus of the Class Crustacea.

(xvi) 2-methyl-3-(methyldithio)furan having the structure: ##STR28## (xvii) aqueous ammonia; and (xviii) yeast extract
taken alone, or in combination with naturally occurring excitants, stimulants, attractants and/or incitants for the Penaeus genus of the Class Crustacea such as natural Crustacean/cephalopod extracts to the vicinity of said desired location or volume. Our invention also describes a process for exciting, attracting, stimulating and/or inciting a member of the Penaeus genus of the Class Crustacea within a volume of water inhabited by such member of the Penaeus genus of the Class Crustacea comprising the step of applying an aqueous solution containing a Crustacean-exciting, attracting, inciting and/or stimulating concentration of one of the above materials (designated as "ASIE" materials) to the vicinity of said volume inhabited by said member of the Penaeus genus of the Class Crustacea. Examples of such members of the Penaeus genus of the Class Crustacea are Penaeus setiferus, Penaeus vannamei and Penaeus aztecus.
The ultimate goal of the ascertainment of such attractancy, stimulation, incitance and/or excitement is to intensify the feeding kinetics (e.g., rate and quantity of food intake and metabolism) for the members of said Penaeus genus. Accordingly, this invention also pertains to a feeding protocol for such Penaeus genus relating to the aforesaid ascertainment and feeding compositions pertaining to said feeding protocol.
Thus, our invention is also directed to feeding compositions for feeding members of the Penaeus genus of the Class Crustacea including (i) prior art feeding compositions (such as RANGEN.RTM.-35, a mixture of 35% protein, 7% fat, fish meal, fish oil and minor amounts of mineral and vitamin nutrients) and also containing, for example, L-ascorbic acid-2-phosphate or its salts as described in Published Japanese Applications J94/093,821 and J94/093,822 assigned to Showa Denko KK and abstracted in the Derwent Patents Index Alerting Abstracts Bulletin for week 9445 issued on Jan. 4, 1995 as follows: SHOW D13 87-253800/36=JP94093821-B2 Food additive for fish farming--contains L-ascorbic acid-2-phosphate or its salts as active ingredient

Our invention is also directed to apparatus for determining whether a given substance at a given aqueous concentration or variable concentrations attracts, excites, incites and/or stimulates at least one member of the Penaeus genus of the Class Crustacea comprising static holding tank means, flow-through holding tank means and/or Y-maze apparatus means.
More specifically, our invention is further directed to apparatus for determining whether a given substance at a given aqueous concentration or variable concentrations excites a member of the Penaeus genus of the Class Crustacea comprising:
(a) static holding tank means containing (i) a volume of water and (ii) at least one live member of the Penaeus genus of the Class Crustacea within said volume of saline water;

(f) variable focus/focal length video camera or camcorder recording means for recording the movements of one or more specified body appendages and/or the lateral direction and velocity of one or more specified body appendages of one or more of the members of the Penaeus genus of the Class Crustacea when the pump injected feeding means and visible light generating means are engaged;
whereby it can be determined whether a particular dilution of a test substance will cause a member of the Penaeus genus of the Class Crustacea to be "excited".
The "recording" by the variable focus/focal length video camera or camcorder recording means is preferably for recording on film or magnetic tape.
An additional aspect of the apparatus of our invention is covered herein for determining whether a given substance at a given aqueous concentration or variable concentrations will attract, excite or incite members of the Penaeus genus of the Class Crustacea. Such apparatus comprises:
(a) flow-through holding tank means where varying concentrations of test solutions are fed in at the inlet of the holding tank means and flow through the holding tank to an exit portal while a member of the Penaeus genus of the Class Crustacea is positioned within the "flow-through" holding tank. The holding tank contains (i) flowing saline water and (ii) at least one live member of the Penaeus genus of the Class Crustacea within the flowing saline water;
(b) pump-injected test solution feeding means for pumping aqueous solutions at variable or preferably constant flow rates of test solution into an orifice in front of the entry portal into the flow-through holding tank;

(d) a first variable power source for energizing or "engaging" the visible light generating means;
(e) a valuable power source for energizing or "engaging" the pump injection feeding means (the pump has variable heads so that the flow rate of the added chemical solution (containing at least one "ASIE") may be added to the basic flow of saline water through the flow-through holding tank);
(f) variable focal length video camera or camcorder recording means for recording the movements and/or the lateral direction and velocity of one or more members of the Penaeus genus of the Class Crustacea when the pump injection feeding means is engaged and when the visible light generating means is engaged; and
(g) specially designed camera platform and blind means (a part of our invention) the purpose of which is to shield the observer from the test animal in order to prevent the test animal from being extraneously stressed and/or distracted. (The variable focal length video camera or camcorder recording means is mounted within the specially designed camera platform and blind means.)
The variable focal length video camera or camcorder recording means is of necessity on a line of visibility between the camera lens and the limits of motion of the member of the Penaeus genus of the Class Crustacea. Accordingly, the apparatus of our invention must contain one or two clear panels behind which is located the video camera or camcorder and in front of which is located at every point of view of the lens of the video camera or camcorder all of the members of the Penaeus genus of the Class Crustacea within the flow-through holding tank or within the static holding tank or within the Y-maze apparatus as the case may be.
More specifically, the variable focus multi-directional video camera or camcorder/video camera or camcorder platform apparatus for facilitating visible wavelength radiation communication between the moving member of the Penaeus genus of the Class Crustacea and an image display of the moving object on, for example, visible radiation sensitive film or visible radiation sensitive magnetic tape comprising:
(1) a horizontal static substantially rectangular planar base located in an "X-Y" plane, having an upper surface and having two substantially parallel ends parallel to the "X" axis and two substantially parallel ends parallel to the "Y" axis; with one end parallel to the "Y" axis being along a line designated "E.sub.1 ";
(2) a vertically disposed substantially rectangular planar frame located in a "Y-Z" plane, substantially perpendicular to said horizontal static planar base and having two parallel ends parallel to the "Y" axis and two parallel ends parallel to the "Z" axis, one of said ends parallel to the "Y" axis being contiguous with said static planar base along a first end, said line E.sub.1 of said static planar base, parallel to the "Y" axis, said frame having a first orifice therethrough permitting visible wavelength radiation to be transmitted therethrough;
(3) a continuous right angle-shaped horizontal/vertical planar base/frame movable platform movable in both the "X" and "Y" (or lateral) directions consisting of (i) a substantially rectangular horizontal lamina located in the "X-Y" plane facing and within the planar framework of said horizontal static planar base (1) plane and having an upper surface and a lower surface continuously and sealably juxtaposed in a direction parallel to line E.sub.1 along a line designated E.sub.2 said line E.sub.2 being proximate said line E.sub.1 with (ii) a substantially rectangular vertical lamina located in the "Y-Z" plane facing and within the planar framework of said vertically disposed frame (2) and containing a vertically disposed visible wavelength radiation shield (blind) having a second orifice therethrough located opposite to and being planarly parallel to and within the planar framework of said first orifice in said vertically disposed frame, said right angle-shaped movable platform being located on rollers juxtaposed with and immediately adjacent said lower surface of said right angle-shaped movable platform and said upper surface of said horizontal static base;
(4) a substantially rectangular rotating planar base having an upper surface and a lower surface and having two parallel ends parallel to the "Y" axis and two parallel ends parallel to the "X-Z" plane, being rotatable about a vertex line E.sub.3 in a hinge manner having a direction parallel to each of lines E.sub.1 and E.sub.2 and being substantially proximate lines E.sub.1 and E.sub.2 along a first parallel hinge end in the "Y" direction parallel to the "Y" axis, having variable manually-controllable rotation movement means located at an end of said rotating planar base opposite said first parallel hinge end, and opposite the location of said line E.sub.3, the direction of rotation of said rotating base being from the location of the "X-Y" plane of said right angle-shaped movable platform towards the location of the "Y-Z" plane of said right angle-shaped movable platform about the said vertex line E.sub.3 ; and
(5) a video camera or camcorder fixedly mounted on the upper surface of said rotating planar base, comprising a housing and a lens located in said housing, the focal plane of said lens being substantially parallel to and at a controllably variable distance from the plane of said first orifice of said vertically disposed frame and said second orifice of said visible wavelength radiation shield with said lens, said first orifice and said second orifice all having a common line of vision,
whereby simultaneous manipulation of said rotating planar base and said right angle-shaped movable platform, when the video camera or camcorder is in operation, facilitate visible wavelength radiation communication between (i) an image display resulting from operation of said video camera or camcorder onto, for example, visible light sensitive film or visible light sensitive magnetic tape and (ii) the image of the moving object (that is the member of the Penaeus genus of the Class Crustacea) being transmitted to said video camera or camcorder.
Another aspect of our invention concerns an additional apparatus for determining whether a given substance at a given aqueous concentration or variable concentrations attracts, or stimulates to feed, or incites to feed, or excites, or stimulates a member of the Penaeus genus of the Class Crustacea; and it comprises a "Y-maze" apparatus similar to that disclosed in a paper by Lee, J. Exp. Mar. Biol. Ecol., Volume 153 (1992), pages 53-67,"Chemotaxis by Octopus maya Voss et Solis in a Y-maze". Although similar to the Y-maze of the instant invention, the apparatus disclosed by Lee in the immediately aforementioned reference is different in kind rather than degree from the apparatus of the instant invention.
More specifically, an aspect of the apparatus of the instant invention comprises, inter alia, a recirculating tank means containing a Y-maze which is a rectangular parallelepiped as its "three-dimensional base" having two rectangular parallelepiped-shaped arms; the three-dimensional base having one closed end and one open end and two sides, each sealably connected to an end panel and each terminating at the open end, said open end connected to two diverging parallelepiped-shaped sections as set forth, supra (having a vertex of 5.degree.-45.degree. (preferably having a 10.degree. vertex)); (i) a test substance input section and (ii) a control section, each of which is sealably connected at the open end to one another and to a side of the first three-dimensional base rectangular parallelepiped section. This apparatus has one or both top and bottom panels as transparent panels whereby a variable focal length video camera or camcorder recording means is maintained on one side of the transparent panel with a line of vision from the lens of the video camera or camcorder to every place where all of the members of the Penaeus genus of the Class Crustacea may travel. It should be noted that the control section and test substance input section can be reversed or interchanged (as by changing the location of the test substance input tube as more particularly shown in FIG. 5G and the detailed description of FIG. 5G in the "Detailed Description of the Drawings" section, infra).
In the Y-maze apparatus of our invention, a constant concentration of the test chemical entering one arm of the Y-maze is the preferred method of addition. In the flow-through apparatus, however, there is a constant increase of concentration of the test chemical during the run.
Furthermore, the Y-maze apparatus of our invention also contains a volume of water and at least one live member of the Penaeus genus of the Class Crustacea within the volume of water. The Y-maze apparatus of our invention contains a pump-injected test solution of test chemical for pumping aqueous solutions of test chemical at various flow rates or preferably constant flow rates into the feeding sections of the Y-maze (at one of the diverging parallelepiped-shaped "arms" connected to the base parallelepiped).
Like the flow-through apparatus and the static tank apparatus, the "Y-maze" apparatus has a visible light generating and guidance means for guiding Visible wavelength light of variable or preferably constant intensity into the volume of water in the holding tank and feeding section where a member of the Penaeus genus of the Class Crustacea is located.
The "Y-maze" aspect of the apparatus of our invention also contains variable focal length video camera or camcorder recording means for recording the movements of one or more appendages and/or the lateral direction and velocity of one or more of the members of the Penaeus genus of the Class Crustacea when the pump injection test chemical means and when the visible light generating means are simultaneously energized or "engaged".
More specifically, in determining a value for the response, "R" or "G" of the member of the Penaeus genus of the Class Crustacea whose responses are measured as a result of the practice of our invention, the time taken for the member of the Penaeus genus of the Class Crustacea to act or to respond to the feeding incitant or stimulant or attractant of our invention is a function of the particular material used and its concentration as well as the flow rate of the liquid.
Proposed mathematical models are set forth herein, to wit: ##EQU1## wherein the term:
.theta.
is the time taken and the terms "G.sub.1 " and "G.sub.2 " are each values for the responses of the members of the Penaeus genus of the Class Crustacea from the initial time "0" of substance injection until the time that a given definitive Crustacean forward motion commences.
It should be noted that the term "G" is also shown herein as "R".
The rate of change of response with respect to test substance concentration (C) (for example, in terms of moles per liter or grams per liter) is given by the equation: ##EQU2## wherein the symbol:
d.theta./dC
is the rate of change of time with respect to concentration, that is, time of response and the symbol:
dG.sub.2 /dC
is the rate of change of response with respect to concentration as is the symbol:
dG.sub.1 /dC
A similar equation is: ##EQU3## which depends on the mathematical model: ##EQU4## Combining the initial mathematical model with the differential equation yields the differential equation: ##EQU5## and the differential equation: ##EQU6##
Changes in response value when concentrations of stimulant change or when concentrations of excitant change or when concentrations of attractant change are shown by the equations: ##EQU7## Thus, for example, in the case of the use of N-acetyl-D-Glucosamine, an epimeric mixture of compounds having the structures: ##STR29## the response versus concentration can be shown by the equation:
--log.sub.10 C=0.8G-2.3
in the static tank, or by one of the equations:
log.sub.10 C=2.3-0.8G;
0.8G=2.3-log.sub.10 C;
G=2.9-1.25log.sub.10 C;
G.sub.1 =2.9-1.25log.sub.10 C;
G.sub.2 =2.9-1.25log.sub.10 C;
G.sub.2 =2.9-2.9log.sub.e C;
Furthermore, the rate of change of response with respect to concentration can be shown by the equations: ##EQU8## and the change in response can be shown by the equation: ##EQU9## Combining the equation
G.sub.1 =2.9-2.9 log.sub.e C
with the equation:
dG.sub.1 /dC==2.9/C
and the equation: ##EQU10## will yield the equation: ##EQU11## (showing concentration as a function of time; when a test chemical is added continuously as when using the flow-through or static apparatus; but not the Y-maze apparatus) and the equation: ##EQU12##
When using the flow-through apparatus and using N-acetyl-D-Glucosamine, an epimeric mixture of compounds having the structures: ##STR30## as an excitant, attractant, stimulant and/or incitant (on a scale of 0-50, as opposed to a scale of 1-5 when using the static tank-containing apparatus), the mathematical models for the mean response as a function of concentration of the N-acetyl-D-Glucosamine, the test chemical, are as follows: ##EQU13## The mathematical model for the median response as a function of concentration of N-acetyl-D-Glucosamine, the test chemical, is as follows:
R=-41.98-5.68 log.sub.10 C
Other materials which were tested but which have not been made a part of our invention are as follows:
(i) Taurine, the compound having the structure: ##STR31## (ii) Guanidine, the compound having the structure: ##STR32## (iii) Betaine, the compound having the structure: ##STR33## (iv) citric acid, the compound having the structure: ##STR34## (v) Pyruvic acid, the compound having the structure: ##STR35## (vi) Ferulic acid, the compound having the structure: ##STR36## (vii) Vanillin, the compound having the structure: ##STR37##
(viii) Isovaleraldehyde, the compound having the structure: ##STR38##
(ix) trans-2-hexenal, the compound having the structure: ##STR39## (x) Citral, the mixture of compounds having the structures: ##STR40## (xi) D-Glucosamine, the epimeric mixture of compounds having the structures: ##STR41##
Each of the substances of our invention tested is diluted in a saline solution containing 30 parts per thousand of a "FRITZ.RTM.", Super Salt concentration manufactured by the Fritz Chemical Company of Dallas, Tex. 75217.

The following application of the feeding behavior:testing protocol was carried out on Paneaus vannamei. Stock solutions were made up at a concentration of 10.sup.-3 molar. 5 Ml of the stock solution is admixed with 500 grams of feed causing 0.5 grams of feed to contain 1.times.10.sup.-8 moles of test chemical. The volume in the aquarium where the feed testing is taking place is 150 liters. Accordingly, the average concentration of the test chemical is 7.times.10.sup.-12 molar. When using 7 ml of test solution rather than 5 ml, the final concentration will be 1.times.10.sup.-11. The actual feed is RANGEN.RTM.35 containing 35% protein, 7% fat, fish meal (without squid) fish oil, and minor amounts of nutrient vitamins and minerals.
The stock solution is diluted to 25 ml with sea water containing 30 ppt of FRITZ.RTM. salt described, supra. 25 Ml of the stock solution is sprayed onto the 500 grams of feed. The water content is increased by approximately 5%. The jar containing the solution is sealed and stored for ten days at 0.degree. C. Prior to use, the contents are shaken well.
The feed level is 0.5 grams of pellets per tank per feeding. The following diets J; P; A and C were used on Paneaus vannamei using the feeding behavior testing protocol described, supra.

Referring to the apparatus of FIG. 2A, the static tank testing system, the static tank system is shown by reference numeral 200. Reference numeral 201 refers to the video monitor. Reference numeral 203 is the vessel holding testing solution 202. Testing solution 202 is pumped through line 204a using peristaltic multihead pump 206 controlled by device 205 pumping solution 202 into tank 208. Tank 208 contains liquid 212 in which Penaeus vannamei or one of the members of the Penaeus genus of the Class Crustacea is at rest on the bottom of the tank which bottom is indicated by reference numeral 214 which may be entirely composed of a clear plastic or glass so that video camera or camcorder 210 may be focused on the movement of the member of the Penaeus genus of the Class Crustacea 10 utilizing the fluorescent light generating device 211. Tank 208 is mounted on stand 209 which surrounds the video camera or camcorder 210 directed towards the tank 208. The surface of the liquid 212 is shown by reference numeral 213. FIG. 7 is a perspective view of the apparatus of FIG. 2A with each of the reference numerals of FIG. 2A repeated.
An example of the light apparatus 211 is a Flexo Heavy-Duty Adjustable Lamp made by Art Specialty Company holding two 18" fluorescent tubes. The tubes are manufactured by the General Electric Company of Schenectady, N.Y. The following specifications for the tubes used are an example of what can be used in the operation of the apparatus of FIGS. 2A and 7:
GE Catalog No. F15TS/CW;

15 Watt;
Rated life of 7,500 hours;
Initial lumens=825;
Mean lumens=725;
Kelvin temperature=4,150; and
CRI rating of 62.
The peristaltic pumps utilizable are those, for example, identified as MASTERFLEX.RTM.L/S manufactured by the Cole-Parmer Instrument Company of 7425 North Oak Park Avenue, Chicago, Ill. 60648 (MASTERFLEX.RTM. being a trademark owned by Cole-Parmer Instrument Company). The pump head is a standard pump head. An example of the MASTERFLEX.RTM. tubing utilized with the MASTERFLEX.RTM. tubing pump (peristaltic pump) is C-FLEX.RTM.06424 (trademark of Cole-Parmer Instrument Company), a styrene-ethylene-butylene modified block copolymer.
Referring to FIG. 3, the flow-through vessel testing apparatus, fluid to be tested 302 is contained in container 303 and pumped through tube 304a using pump 306b and then through tube 304b into location 325 and then into vessel 350. Vessel 350 contains the member of the Penaeus genus of the Class Crustacea 10' and 10" located in the flowing liquid 312. Meanwhile, the liquid 312 is circulating by means of pump 306a through line 324a and then through 324b into tube 326a and fitting 331a where it joins with the feeding fluid (test material) at 325. The combined liquids having ever-increasing concentration of material from vessel 303 travels through holding vessel 350 into exit tube 331b past fitting 329 into tube 326b where again it is recirculated. The exit portion of the flow-through tank is 351b and the entrance portion is 351a.
The Penaeus vannamei is placed in section 351b to acclimate with only saline water 312 circulating. The experiment is started by adding liquid (302) to the liquid 312 and removing the barrier 930. The motion of Penaeus vannamei 10 from position 10" to 10' is monitored by 310 and displayed on 301.
Meanwhile, the motions of the member of the Penaeus genus of the Class Crustacea 10' and 10" is recorded using video camera or camcorder 310 shown on monitor 301. Simultaneously, light source 311 directs light into flow-through vessel 350. The side of the flow-through vessel has a clear plate through which camera 310 has a direction of vision. Screen 330 is held in place at 335. Screen 330 divides the flow-through tank between sections 351a, the entrance section and 351b, the exit section. As shown in FIGS. 3A, 3B and 3C, fluid entering the flow-through holding tank 350 enters from tube 352a and exits from tube 352b. Additional testing fluid enters through tube 304b and enters the elbow mixing with fluid from 326a at 331a. Fitting 326a is threaded into elbow 325 at 329. Fluid exits at 352b entering elbow 331b. Fitting 326b is threaded into the elbow at 329.
Referring to FIG. 4, FIG. 4 shows a side elevation view partially cut-away of apparatus showing in detail the variable focus/focal length video camera or camcorder, camera platform and shield used with the light in conjunction with the test chamber. Chamber 408 could be a flow-through chamber containing fluid 412 therein. Light source 411 emits visible wavelength radiation into the tank 408 and into the fluid 412 simultaneously with the action of video camera 410 strapped to platform 414 with bungee cord 421. Video camera 410 is mounted on a height adjuster 452 having a movable height adjustment screw 413 and imbedded ball bearings 430 at a solid surface indicated by 415. The camera is mounted so that the lens, lens shield 470 and the liquid 412 are on a direct visual line as a result of an orifice being in supporting frame 419 and another orifice indicated by reference numeral 418 being in shield 417. Supporting frame 419 and the camera lens are shielded by cloth 420 which prevents the member of the Penaeus genus of the Class Crustacea 10 from being distracted by the movement of the video camera. Thus, camera 410 may be adjusted laterally and vertically, the vertical angle adjustment coming through the use of adjustment screw 413 and the lateral travel coming through the travel using bearings 430 on the solid travel surface or lamina 415.
FIG. 4A is a detailed section of the shield 417 having attached thereto a supporting frame guide 422 at an angle preferably of 45.degree. to the shield 417. 418 indicates the orifice mentioned in the detailed description of FIG. 4.

FIG. 5A is a top cut-away view of a Y-maze apparatus for testing chemo-attractancy of a substance. The Y-maze apparatus is indicated in general by reference numeral 500. The member of the Penaeus genus of the Class Crustacea 10 may or may not be attracted to an attractant or it may or may not be excited by an excitant. In any event, the feed line inflow fittings 560 are located at the end of the Y-maze 509a and 509b.
Thus, the test section of the Y-maze is indicated by 509a and the control section is indicated by 509b or vice versa (these two sections can be reversed by changing the chemical feed lines as shown in FIG. 5G and discussed in detail, infra). Both sections join at 540 with a joining wall 543.
The "control section" and the "testing substance input section" (also indicated by the letters "A" and "B" which can be interchanged) are at an angle "alpha" from one another, alpha being 5.degree.-45.degree., preferably 10.degree.. These sections as stated, supra, are interchangeable. The vertex of the angle is at reference numeral 540. An optional feeding station also exists in the Y-maze test section and is indicated by reference numeral 596 and in the control section at 597. Baffle plates 501a, 501b, 501c and 501d (also called "flow screens") are located close to the end 509a and 509b close to the inflow fitting 560 coming from the feed fluid peristaltic pump. The testing section is indicated overall by reference numeral 520 or 521 and the control section is indicated overall by reference numeral 520 or 521 since the two sections can be reversed by changing the chemical feed lines as shown in the detailed description of FIG. 5G, infra. The feeding section and the control section are separated by a removable screen 503 from the main section of the Y-maze 522 in which the member of the Penaeus genus of the Class crustacea 10 is located. The sides of the main section 522 are indicated by reference numerals 508a and 508b. The back end of the Y-maze 522 which is in the shape of a rectangular parallelepiped contains two drain lines 562a and 562b and a flush port 561, the back section being indicated by reference numeral 526. A baffle between the back section 526 and the main section of the Y-maze 522 is indicated by reference numeral 590. The flow of liquid travels through portal 570 underneath perforated wall 590 and around baffle 524 to the drain. The fluid level is also shown in the side view in FIG. 5B and is indicated by reference numeral 513.
FIGS. 5E and 5F show yet another embodiment of the Y-maze apparatus test tank of our invention. In this case, the baffle 590 is replaced by a curved perforated wall 590a. The embodiments of FIGS. 5C and 5D are indicated, overall, by reference numeral 510.
FIGS. 5C and 5D show yet another embodiment of the Y-maze apparatus of our invention, indicated by reference numeral 520. In this case, the perforated walls 590 and 590a are replaced by perforated walls 591a and 592a which contains perforated gate 593 which is removable. Fluid moves past the screen 593 and through weir 524 in exiting from the Y-maze.
FIG. 5G is a schematic diagram of the use of the Y-maze which is indicated by reference numeral 500 and which can be any of the Y-mazes as illustrated in FIGS. 5A, 5B, 5C, 5D, 5E or 5F.
The operation of the Y-maze is in two phases, phase I and phase II. In phase I, the "preparation" and "acclimation" phase, water is recirculated and no chemicals are tested. The test procedure is in phase II. In phase I, fluid passes through 572a and 572b through line 572 into recirculation bucket 571 and then through valve 574 which is open (valve 577 is closed for phase I). The fluid is then pumped using pump 578 through line 579 (pump 578 being also indicated as pump C). The fluid then travels through lines 579a and 579b into sections "A" and "B" of the Y-maze, through lines 660a and 660b and through openings 509a and 509b and lines 560a and 560b. During this procedure, valves 662 and 673 are closed.
In phase II, solution is pumped from either tank 666 (the liquid being indicated as 667) or liquid 668 is pumped from an alternative tank. The liquids being control or test liquids. Quick connect nipples 672a and 672b are interchangeable; and quick connect nipples 675a and 675b are also interchangeable, physically. Thus, either fluid is pumped through line 671b or is pumped through line 671a and fluid is either pumped through line 663a or line 663b. In phase II, valve 577 is open and valve 574 is closed.
New water 575 is pumped through line 576 past valve 577 using pump C, pump 578 through lines 579a and 579b. Then, pump B, pump 670 pumps liquid 668 through line 669 either into line 671b or 671a depending on which line is connected using the quick connect nipples 672a and 672b. In any event, the fluid is pumped past valve 673 through line 660b. By the same token, liquid A from tank 666, the liquid being also shown by reference numeral 667 is pumped through line 665 and then either through line 663b or line 663a depending on whether the lines are connected using quick connect nipple 675b or 675a. In any event, the fluid is pumped past valve 662 through line 660 past fitting 560a into section "A" of the Y-maze, the operation of which is described, supra. The liquid 667 is pumped using pump A, pump 664. Pumps A, B and C, that is pump 664, pump 670 and pump 578 are driven by pump drives 676.

�--log.sub.10 C!
versus response "R" for three different flow rates using the flow-through apparatus of FIGS. 3 and 3B. The graph indicated by reference numeral 2000 is for a flow rate of 125 ml/minute and is a straight line through data points 2001 and 2002. The graph for a flow rate of 100 ml/minute is indicated by reference numeral 2020 and is a straight line through data points 2021 and 2022. The graph indicated by reference numeral 2010 is for a flow rate of 75 ml/minute and is a straight line through data points 2011 and 2012.
When using as test materials the ammonium chloride, ammonium acetate, aqueous ammonia and acetic acid as set forth, supra, a number of equilibria exist:
NH.sub.4.sup.+ +H.sub.2 O.revreaction.H+NH.sub.4 OH;
NH.sub.4 OH.revreaction.NH.sub.4.sup.+ +OH.sup.- ;
H.sub.2 O.revreaction.H.sup.+ +OH.sup.- ; ##STR91##
For the equation:
NH.sub.4.sup.+ +H.sub.2 O.revreaction.H.sup.+ +NH.sub.4 OH,
the relationship: ##EQU14## exists. For the equilibrium:
NH.sub.4 OH.revreaction.NH.sub.4.sup.+ +OH.sup.-,
the relationship:
K.sub.i =1.8.times.10.sup.-5
exists.
For the equilibrium:
H.sub.2 O.revreaction.H.sup.+ +OH.sup.-
the relationship:
K.sub.w =10.sup.-14
exists.
For the equilibrium: ##STR92## the relationship:
K.sub.3 -=1.8.times.10.sup.-5
exists.
When ammonium acetate having the structure: ##STR93## hydrolyzes, according to the equilibrium: ##STR94## the acetic acid and aqueous ammonia further hydrolyze to form acetate ions and ammonium ions and the relationship for the hydrolysis constant:
K.sub.hAA
for ammonium acetate is: ##EQU15##
For example, at a concentration of 10.sup.-9 for the ien:
�NH.sub.4.sup.+ !
the amount of hydrolysis to aqueous ammonia is negligible since the hydrolysis constant is 5.5.times.10.sup.-10.
At an initial concentration,
�NH.sub.4 OH!
of 10.sup.-12 the amount of ionization to ammonium ion is negligible since K.sub.i is 1.8.times.10.sup.-5.
Since all of the above equilibria are in saline solution containing chloride cations and metal anions such as sodium ion, many ion pairs exist and the standard equilibria and mathematical relationships are accordingly altered.
