Modelling Fish Behaviour in Trawl & Purse seine Yonghae Kim

This book suggests new idea of behaviour modelling by using Chaos theory. Erratic, irregular or complex movements of fish are represented by establishing a model of Psycho-hydraulic wheel by hydraulic instinct model and Lorenz chaos. This model of chaotic fish behaviour is applied as stimulus-response for capture process of towed fishing gear and purse seine as well as produced fish migration circuit. This book opens most of model source codes. It could be very useful to examine catch rate or selectivity for relevant fishing gear. The main features in this book are as follow. Geometry of fishing gear as stimuliSensitivity of sense organ in fishRelationship between Stimulus- ResponseChaotic fish behaviour modellingVariation of fish movement components Fish capture process as escape or caught Modelling fish migration as annual circuit
