Synopsis

From the point of view of fishery management, information from computations of the kinds described in this Bulletin provide only a part of the basic information upon which policy can be based. Sometimes, to be sure, they can provide the greater part of the necessary information. This is particularly true where several species are possible occupants of and competitors for an important environment, and their relative abundance may vary with the intensity for the fishery or with physical changes. This Bulletin is of course not intended as a complete text book for fishery biologists. Methods of measuring fish, determining their age, marking, tagging, collecting, and tabulating catch statistics--all these are mentioned only incidentally, although they provide the data from which the vital statistics of a stock must be estimated.
