Thermal hatchery marks of salmon collect from the Gulf of Alaska 2001-2004

Analysis of salmon otoliths for hatchery thermal marks and Genetic Stock Identification techniques were used to determine the home stream of hatchery and wild stocks in the Gulf of Alaska and their distribution with respect to oceanographic regimes. Factors affecting the distribution of juvenile salmon in the Gulf of Alaska were examined to determine what biological and physical factors influence the distribution of juvenile salmon. CTD, ADCP and stomach analyses of trawled salmon were examined. Retrospective analysis of catch per unit effort versus oceanographic and prey factors will reveal what affects the distribution of pink, chum, coho and sockeye salmon in the study region.
Data were collected from the following cruises: GP0108, GP0207, GP0401 and MF0310.
