FISH 3.1 is a computer program designed by University of Victoria professor Robert Gifford and programmed by Jonas Gifford for studying the resource management behavior of individuals and small groups.

FISH 3.1 can be run with all human fishers (any number at one time), or with one human fisher and any number of computer fishers. It is written entirely in Java 1.1 and is portable to any Java-enabled platform.

Specifically, FISH 3.1 allows the study's investigator to define:
