Abstract

Loligo Duvauceli, is known as squid in the local name. Squid is a species of high value and a good source of protein besides fish. This paper presents a model of dynamic squid behaviour and a system dynamic model. The purpose of the model is to develop a sustainable model for squid population, growth and harvesting. This model is carried out through several basic tests to determine its sensitivity to changes in crucial parameter and initial value with different value and boundary conditions. The model result shows that growth, biological catch and harvesting must be adjusted quickly in response to changing conditions to improve fishery sustainability.
