NOAA Photo Library Image - fish7922

On board a BCF research vessel, fishery biologists are measuring fish and taking blood samples for stock analysis. Each species of fish or shellfish is composed of stocks or subpopulations, which may differ slightly in structure, physiology, or rate of growth. Information on stocks enables biologists to determine the sustainable yield of each stock.
