Abstract:: Cell lines were established from spleen and heart tissues of a juvenile white sturgeon Acipenser transmontanus and designated WSS-2 and WSH-1, respectively. Isoenzyme analyses of both lines confirmed their host of origin. Both lines were hypotetraploid and possessed micro- and macrochromosomes. The modal chromosome number for the WSS-2 line was...

Abstract:: Juvenile English sole, Parophrys vetulus utilize Yaquina Bay, Oregon, as a nursery during at least a portion of their first year of life, but the possibility of the existence of additional nursery grounds offshore has not previously been examined. During 1971, young-of the-year first appeared in Yaquina Bay in February,...

Abstract:: The sablefish Anoplopoma fimbria is a valuable North Pacific Ocean species that, when not targeted in various commercial fisheries, is often a part of discarded bycatch. Predictions of the survival of discarded fish are dependent on understanding how a fish responds to stressful conditions. Our objective was to describe the...

Creator:: Sigismondi, Linda A. and Weber, Lavern J.
Abstract:: A simple behavioral test was devised to determine the effects of multiple acute stresses on the avoidance response time of fish. Groups of freshwater-adapted juvenile chinook salmon Oncorhynchus tshawytscha were exposed to a sudden overhead light and the time it took each fish to reach cover was noted. Tests were...

Abstract:: The diel feeding periodicity of juvenile Chinook salmon Oncorhynchus tshawytscha was determined from stomachs collected in coastal waters off Oregon in 2000 and 2003. Juvenile Chinook salmon exhibited a diurnal feeding pattern with morning and evening feeding periods. There were differences in the duration and magnitude of the dawn and...

Abstract:: Juvenile red hake Urophycis chuss were collected while they were inhabiting sea scallops Placopecten magellanicus , and the effects of appetite and food availability on prey consumption and growth were examined under laboratory conditions. Fish took increasing amounts of live amphipods Gammarus annulatus with increasing periods of food deprivation up...

Abstract:: We examined the diets and weight-length relationships of juvenile bluefish Pomatomus saltatrix from Sandy Hook Bay, New Jersey, during 1981, 1983, and 1984. Diets consisted of a variety of polychaete, crustacean, and fish prey. Opossum shrimp Neomysis americana. sand shrimp Crangon septemspinosa, grass shrimp Palaemonetes vulgar is, bay anchovy Anchoa...

Abstract:: Abnormalities including contortion of the body and reduction of the jaws and pectoral fins occurred among 2-25% of the yolk-sac Pacific herring larvae Clupea harengus pallasi collected in 1985 from Kulleet Bay, a spawning area on Vancouver Island, British Columbia. An additional 4-68% of the post-yolk-sac larvae had underdeveloped lower...

Abstract:: We evaluated the effect of barotrauma on the behavior of nine species of Pacific rockfish Sebastes spp. after hook-and-line capture and release using a video-equipped underwater release cage. Sampling was conducted across a range of bottom depths (12-194 m), mostly where barotrauma resulting from an expanded swim bladder and gaseous...

Abstract:: Efforts to restore depressed populations of Pacific salmon Oncorhynchus spp. are often hampered by the inability to assign population identity to individuals in an admixture. This knowledge is of particular concern in supportive breeding programs, in which misidentification of individuals to population may result in progeny of mixed heritage, which,...
