FISH 3.1 Home Page
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. It is useful for studies often called commons dilemmas, resource dilemmas, social
dilemmas, or social traps. 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.
FISH 3.1 supports a fully networked and interactive environment. Any
number of oceans can be
managed by one server program, and any number of participants from anywhere on the internet
from any mixture of Java-enabled platforms can share these oceans and fish in real time.
Specifically, FISH 3.1 allows the study's investigator to define:
- the size of the fish stock (the maximum is several hundred)
- the number of seasons (replenishment trials) for the simulation (no maximum)
- the regeneration rate of the fish stock
- the greediness of computer fishers
- the uncertainty in the fish stock
- the probability that a cast will be successful (from 0 to 1)
- which information is displayed about the other fishers
- the profits and expenses of fishing, including
- the cost per second of being at sea
- the cost of leaving port
- the profits per fish
- the initial balances of all fishers
- the messages that appear as instructions before the simulation begins, and the messages that
are shown after the simulation ends
