- Abstract
The article relates a study examining the timing of catches of sockeye salmon in the commercial districts of Egegik and Ugashik in Bristol Bay, Alaska. The study revealed that the fishing rates have changed over the course of the migration period, the patterns of selection is different in the two districts and the patterns varied over the decades. The balance between genetic and environmental control of migration and breeding timing may vary among fishes, and instances of shifting migration timing can have an increasingly environmental foundation. The study found that many fisheries exploit migratory species because they are abundant and the essential features of migration greatly increase capture efficiency.
