Fish Shuttle Avoidance Tank
The ENV-012 package uses a 5-1/2 gallon glass aquarium with several modifications for shuttle avoidance. The dimensions of the tank measure 15-7/8"L x 10-1/4"W x 9-3/4"H (40 x 26 x 25 cm). The bottom of the tank contains two 5-3/4" x 7-3/4" stainless steel aversive stimulation plates separated by an inverted "V" shaped shuttle 2-1/4" (5.7 cm) tall. Just below the water line located 4-1/4" from the bottom are two top aversive stimulation plates similar to the bottom plates. Extending above the shuttle is a removable insert containing a port 1-5/8"H x 3"W (4 x 7.6 cm) through which the fish must swim to avoid or escape aversive stimulation.
Two photobeam holders are placed across the tank. Each holds a pair of sensors, one on top of the other separated vertically 0.787" (2 cm). The holders provide for an adjustable horizontal separation of 0.787", 1.55", 2.362", or 3.150" (2, 4, 6, or 8 cm) with the barrier in the middle. Four ENV- 253SD Photo Beam Source and Detector Packages and an ENV-253 Four Channel I/R Photo Beam Control are required to automate response detection.
Also illustrated are two stimulus light holders on the outside of the tank at each end, and a buzzer placed in the waterproof support that separates the two aversive stimulation plates.
The stimulus lights, sensors, aversive stimulators, I/R control, computer interface and software may be ordered separately.
