Movements of spawning sockeye salmon in Hidden Creek, Brooks Lake, Alaska

Creator:

Tsunoda, Setsuwo

Abstract:

The movements of a population of adult sockeye salmon (Oncorhynchus nerka) were followed in a small tributary of Brooks Lake, Alaska until spawning was nearly complete in 1963. The objectives of the study were to describe the movements of sockeye salmon on the spawning ground of an entire small stream,...

The association and distribution of fish species in Nyanza Gulf, Lake Victoria, East Africa, 1975

Creator:

Wanjala, Benny

Abstract:

A trawling survey was conducted on Nyanza Gulf, Lake Victoria, East Africa during March-December 1975 to investigate association and distribution of the major fish species and to provide information for management of the fishery. A total of 139 sites was sampled and all fishes caught were counted, measured, and weighed....

Age determination of corvina reina (Cynoscion albus) in the Gulf of Nicoya, based on otolith surface readings and microincrement analysis

Creator:

Mug-Villanueva, Moises

Abstract:

The corvina reina (Cynoscion albus) is an important part of the artisanal fishery in the Gulf of Nicoya, Costa Rica. Stock assessment on this sciaenid species has been restricted to the use of length-based methods because of the lack of age data. Direct age determination methodologies for tropical species often...

Scale patterns indicate changes in use of rearing habitat by juvenile coho salmon, Oncorhynchus kisutch, from 1955 to 1984 in the Tenmile Lakes, Oregon

Creator:

Gunnarsdottir, Hugrun

Abstract:

This study was designed to provide information about the juvenile life history of coho salmon, Oncorhynchus kisutch, in the Tenmile Lakes in Oregon by 1) classifying scales of spawning fish and outgoing smolts (1+), 2) assessing the contribution of juvenile life history types to the returns of adults (3₂) and...

Changes in size and age at maturity of Columbia River upriver bright fall chinook salmon (Oncorhynchus tshawytscha) : implications for stock fitness, commercial value, and management

Creator:

Beaty, Roy E.

Abstract:

The average size and age of chinook salmon (Oncorhynchus tshawytscha) caught in commercial fisheries along the Pacific Coast of North America have decreased substantially in this century. These declines might be caused in part by changes in size and age at maturity within the stocks contributing to those fisheries. Upriver...

Effects of logging on the growth of juvenile coho salmon

Creator:

Iwanaga, Paul M.

Abstract:

The objective of this research was to study the effects of increased water temperature characteristic of clearcut watersheds of Pacific coastal streams upon the growth rate of juvenile coho salmon. The natural temperature fluctuations of the stream were used in the study of growth of underyearling fish held in aquariums...

Distribution and survival of coho salmon fry after emigration from natal streams

Creator:

Lindsay, Robert Bryan

Abstract:

Large numbers of coho salmon (Oncorhynehus kisutch) fry move downstream shortly after emergence from the gravel in many spawning tributaries. In three small coastal streams of Oregon about eight times more juveniles leave the tributaries as newly emerged fry than as smolts one year later. Because these early emigrants comprise...

Metabolism of periphyton communities in two small streams

Creator:

Lane, Charles Bertell

Abstract:

A technique for estimating gross primary production and respiration of periphyton communities, in situ, in small turbulent streams was developed using a photosynthesis-respiration chamber in a modified "light and dark bottle" method. Trays containing portions of the substrate bearing the benthic community were embedded in the stream, level with the...
