Paperback. Condición: New. Print on Demand. This book presents information on the haddock population of Georges Bank, a large underwater plateau off the coast of New England. The study was based on data collected during three surveys conducted by the U.S. Fish and Wildlife Service between 1948 and 1950. The author presents data on the total abundance and age composition of haddock on the bank by statistical subarea, depth, and bottom type, during spring and summer. The book discusses topics such as abundance and age composition for Georges Bank, summer and spring abundance and age composition in individual subareas, abundance and age composition as related to depth and bottom type, and comparison of census and commercial data. The author's aim was to provide reliable data on the distribution of the haddock population and to estimate mortality rates and year-class strength. The insights in this book are significant for understanding the population dynamics of haddock and for developing effective management strategies to ensure the sustainability of this valuable fishery resource.
