Abstract
In many fisheries sharing information between vessels is an important
characteristic of fishermen's behaviour rarely modelled or analyzed. A
Cellular Automaton is designed in an attempt to understand circumstances
that favour group formation. The simulated world is toroidal with a
static fishing resource distributed in patches. Movement decisions are
random in the case of fishermen in a local scale. After a certain time
interval, sharing information is possible between fishermen in a dynamic
Moore's neighbourhood of cells at a broader scale and movement to
adjacent areas may occur according to a set of rules. The dynamic
neighbourhood is a novel concept defined in this work within the
framework of Cellular Automata. Decision making by each fisherman is a
function of the influence other fishermen (neighbours) exert on them as
well as on personal knowledge, to form an opinion of the areas (cells)
quality, and take action consequently. (c) 2005 Elsevier B.V. All rights
