This book constitutes the first of a series of three volumes, the purpose of which is to cover the principal methods used in fish population dynamics. It is devoted to the definition of the main concepts, ami the presentation of the usual mathematical models. The second volume will deal with the fitting of the models, and the estimation of parameters. The third will be devoted to sampling problems. These volumes will be recollections of communications presented during ad hoc seminars, hold in Brest (GSG/COB) in 1980 and 1981. The first part deals with the basic concepts related to the two components whose relationship is being described by the population dynamics, namely the fish stock, to its relations with biological populations, and to the partition of... |
