Fish As Food: Volume I

Fisheries are always faced with two questions: how to increase yields without considerable additional costs, and how to avoid fluctuations in the catches. To a certain degree, these questions are technical and economic, because through intensifying fishing in many ocean regions and by means of improvements and rationalization in catching methods, considerable progress in increasing and stabilizing the yields is still feasible (Walford, 1958). In the end, however, there are limitations to these efforts set by the restricted productivity of the fish population.
