Recruitment prediction is a key element for management decisions in many fisheries. A new approach using
neural network is developed as a tool to produce a formula for forecasting fish stock recruitment. In order to
deal with the local minimum problem in training neural network with back-propagation algorithm and to
enhance forecasting precision, neural network’s weights are adjusted by optimization algorithm. It is
demonstrated that a well trained artificial neural network reveals an extremely fast convergence and a high
degree of accuracy in the prediction of fish stock recruitment.
