In the Fish Lab at the Rowland Institute, we explore perceptual and cognitive capabilities in fish. Recently completed work used koi carp as subjects in investigations of high-level stimulus control involving complex auditory stimuli, including music. A new paper describes this work (Ava Chase. Music discriminations by carp (Cyprinus carpio). Animal Learning & Behavior, 2001, 29(4), 336-353). Reprints will be sent upon request, or a 1.2MB Acrobat .pdf file of the paper can be [downloaded here].
There is a short discussion of one of the experiments in the paper (the melody experiment) and two movie files [click here].
The lab has also collaborated with U-Mass Dartmouth and others to develop optimal feeding formulations and schedules for the aquaculture of tilapia.
To support all of the above work we have developed new reliable apparatus,
including a horizontal response button and a feeding system that dispenses
solid food underwater through a nipple (Ava Chase & Winfield Hill.
Reliable operant apparatus for fish: audio stimulus generator, response
button, & pellet-dispensing nipple. Behavior Research Methods, Instruments,
& Computers, 31(3):470-478, 1999). A 2.6MB .pdf file
of the paper can be [downloaded here].
Our early work focused on color vision, specifically color-constancy in goldfish (David Ingle. The goldfish as a retinex animal. Science,227(4687):651-654, 8 February 1985).
