摘要:

A review is made of some optimization techniques appiled to fisheries and related problems. Explanations of optimal control theory as applied to the Schaefer or logistic model and to the Beverton and Holt model are provided. An optimal policy for a fishery management model based on the Brody growth function is developed. The control variable in each of the above examples is the rate of fishing and the objective function is the maximum biomass yield. A method for estimating the parameters of the Brody growth function is illustrated for the albacore tuna.

摘要:

A conceptual model of the decision-making process in fisheries management is presented in conjunction with applications of computer and systems analysis to this process. One of the most difficult problems to solve is selecting objectives to be used for management evaluation. An objective function based on some or all of the components of yield, species, size desirability, and environmental quality is needed. Systems analysis and computer technology in data processing and simulation may be used in many situations to evaluate decision alternatives as an aid in developing management strategies.
