  Sea fishing is a highly mobile activity, favoured by the vastness of the
oceans, the absence of physical boundaries and the abstraction of legislative
boundaries. Understanding and anticipating this mobility is a major challenge
for fisheries management issues, both at the national and international levels.
''FisherMob'' is a free Gama tool designed to study the effect of economic and
biological factors on the dynamics of connected fisheries. It incorporate the
most important processes involved in fisheries dynamics: fish abundance
variability, price of the fishing effort and ex-vessel fish market price that
which depends on the ratio between offer and demand. The tool uses as input a
scheme of a coastal area with delimited fishing sites, fish biological
parameters and fisheries parameters. It runs with a userfriendly graphic
interface and generates output files that can be post-processed easily using
graphic and statistical software.
