Paperback. Zustand: New. Print on Demand. This volume summarizes the United States Bureau of Fisheriesâ work during 1925. Investigations into a range of saltwater species are detailed, including cod, pollock, mackerel, mullet, smelt, Coregonus, salmon and herring. It presents data from tagging experiments, biological analysis, and ecological monitoring. These studies were driven by a desire to understand population fluctuations and depletion drivers in order to ensure the sustainable management and conservation of valuable fisheries and species. Increased knowledge of migratory patterns, habitat preferences, and life cycles helped the bureau to develop practical recommendations for policymakers and fishermen alike.
