Survival and Behavior of Sockeye Salmon Fry Migrating into Brooks Lake, Alaska
Hartman WL, Strickland CW, Hoopes DT. 1962. Survival and Behavior of Sockeye Salmon Fry Migrating into Brooks Lake, Alaska. Transactions of the American Fisheries Society. 91(2):133-139
This paper describes the behavior of sockeye salmon fry during their migration from stream spawning gravels to lake nursery area. Fry were negatively phototactic, sought holding areas along stream banks during daylight hours, and only left holding areas and gravel to migrate during the darkest hours of the night. Fry migrated as individuals, facing downstream, and usually exhibited swimming movements. Certain features of the migratory behavior are discussed in terms of survival values in the face of intense piscivorous predation.
