The purpose of this study was to measure the total lipid and cholesterol content and fatty acid profile of chinook salmon (Oncorhynchus tshawytscha), Dover sole (Microstomus pacificus), and sablefish (Anoplopoma fimbria). All three species of fish were caught off the coast of Oregon in late summer, 1987. Salmon contained 6.95% total lipid, Dover sole contained 1.03%, and sablefish contained 5.7...

This report describes the food habits of some commercially important groundfish collected off the coasts of California, Oregon, Washington, and British Columbia. Generally, the groundfish reported on were sampled during three cruises the triennial groundfish survey of 1989 and the continental slope surveys of 1991 and 1992. Some young-of-the-year Pacific hake (also known as Pacific whiting, Mer...

—Fisheries models often assume that discarded undersized fish and target species will survive and contribute to future recruitment and yield. If smaller fish are more susceptible to capture stressors than larger fish, then the assumption that smaller discards would contribute to recruitment may not be true. We tested the hypothesis that small sablefish Anoplopoma fimbria show more behavioral im...

Sablefish, Anoplopoma fimbria (also called black cod), is a long-lived marine species with wide distribution extending from Baja California to Alaska, the Bering Sea, and through eastern coast of Japan. The landed weight sablefish in U.S. commercial fisheries not large compared other species; however, exceptional value has ranked it high such as pollock, sockeye salmon, Pacific cod. Sablefish a...

A total of 7,899 stomachs from 40 species, walleye pollock (Theragra chalcogramma), Pacific cod (Gadus macrocephalus), arrowtooth flounder (Atheresthes stomias), Pacific halibut (Hippoglossus stenolepis), sablefish (Anoplopoma fimbria), spiny dogfish (Squalus acanthias), big skate (Raja binoculata), Bering skate (Bathyraja interrupta), Alaska skate (Bathyraja parmifera), longnose skate (Raja rh...

Understanding how energy allocation changes with ontogeny can provide insights about survival bottlenecks during early life stages for marine fishes. Energy in juvenile fish before and their critical first winter differs among species based on history foraging characteristics. To improve understanding of energy-size relationships fish, we examined seasonal sablefish Anoplopoma fimbria , a unusu...

The Pacific Coast groundfish fishery is conducted along the entire coastline of Washington, Oregon, and California, and includes a diverse range of habitats, species, and participants. The Pacific Fishery Management Council’s (PFMC) Groundfish Fishery Management Plan (FMP) contains more than 90 species organized into several sub-fisheries, including 1) the Dover sole, thornyheads, and sablefish...
