An Annotated Bibliography of the Ecology of the Co-Occurring Tunas (Katsuwonus pelomis, Thunnus albacares) and Dolphins (Stenella attenuata, Stenella longirostris and Delphinus delphus) in the Easter Tropical Pacific

Description: From introduction: This bibliography was compiled to provide a source of information on the ecology of the co-occurring tunas and dolphins in the Eastern Tropical Pacific (ETP). While some of the articles give information concerning distribution and ecology of tunas and dolphins in other geographic areas, the primary focus is on the tunas and dolphins that occur together in the ETP.

Effects of Flow on the Migratory Behavior and Survival of Juvenile Fall and Summer Chinook Salmon in John Day Reservoir, 1981 Annual Report of Research.

Description: Research was conducted by NMFS in 1981 to define the effects of instream flows on the passage time, survival, and migrational behavior of 0-age chinook salmon in John Day Reservoir. Fourteen groups (74,683 fish) of marked 0-age chinook salmon were wire-tagged, branded, and released into the tailrace at McNary Dam, fourteen groups (13,746 fish) were branded and released into the reservoir at River Kilometer 375, and 34 groups (14,273) were branded and released into the reservoir at various other sites. More than 55,000 0-age chinook salmon were sampled at the John Day Dam airlift facility. This sample included 623 mark recoveries. Four hundred and eight (408) additional marks were recovered from purse seine samples taken at various sites throughout the reservoir. The average passage time of marked 0-age chinook salmon released in the McNary trailrace was 22 days in 1981. There was no statistically significant evidence to indicate that instream flows affected either the rate of movement or residence time of 0-age chinook salmon in John Day Reservoir in 1981. 7 references, 1 figure, 12 tables.

Structured Flotsam as Fish Aggregating Devices

Description: Abstract: A modern adaptation of an old fishing technique is gaining recognition in the Pacific and elsewhere as an effective means to increase fishing productivity in the open sea. The use of man-made, free-floating, and anchored floating devices to aggregate pelagic fishes for subsistence, recreational and commercial fishing has increased markedly in recent years; estimates of deployed and planned units exceed 1,000. These devices have been anchored in depths ranging from several hundred to several thousand fathoms. This report reviews the development and present use of fish aggregating devices in the Pacific and Indian Oceans.
