Summary
There seems to be general agreement among fisheries scientists that fishing has a significant impact on the dynamics of fish populations, and that this impact is dependent on the status of the stocks. Numerical studies were conducted on the effects of trawl and longline catches on a cod stock and possible yields from it. The study focuses on these effects considering different catch level and age composition of catch on the stock remaining in the sea, using a numerical model. Results indicate that the catching strategy should be taken into consideration for proper management of fish stocks.
