Mass Abundances of Abnormal Pacific Herring Larvae at a Spawning Ground in British Columbia

Creator:

Purcell, Jennifer E., Grosse, Daniel, and Grover, Jill J.

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...

Body Size and Growth Rate Influence Emigration Timing of Oncorhynchus mykiss

Creator:

Tattam, Ian A., Ruzycki, James R., Li, Hiram W., and Giannico, Guillermo R.

Abstract:

Juvenile Oncorhynchus mykiss migrate extensively in freshwater during fall. We used individual tagging to study the spatial origin, influences, and outcomes of fall migration on fish that emigrated from summer rearing tributaries during fall (early-emigrants) and those that did not (late-emigrants) in the South Fork John Day River, Oregon. Fall...

Buoyancy regulation by hatchery and wild coho salmon during the transition from freshwater to marine environments

Creator:

Weitkamp, Laurie A.

Abstract:

One aspect of diadromy that has received little attention is buoyancy regulation in fish moving between freshwater and marine environments. Because of density differences between the two water types, fish must alter their whole-fish density (WFD) or they will become positively (float) or negatively (sink) buoyant as they change environments....

Correspondence between Scale Morphometrics and Scale and Otolith Chemistry for Interpreting Juvenile Salmon Life Histories

Creator:

Campbell, Lance A., Bottom, Daniel L., Volk, Eric C., and Fleming, Ian A.

Abstract:

Fish scales have long been used to reconstruct fine-scale habitat transitions such as the movement of juvenile fish from freshwater, estuary, and ocean environments. Despite the importance of life history information to fisheries management and conservation, few studies have validated that scale morphology accurately describes fish movement between these habitats....

Ontogenetic shifts in diets of juvenile and subadult coho and chinook salmon in coastal marine waters: important for marine survival?

Creator:

Daly, Elizabeth A., Brodeur, Richard D., and Weitkamp, Laurie A.

Abstract:

Successfully shifting to a more piscivorous diet may be an important factor in the growth and survival of juvenile coho salmon Oncorhynchus kisutch and Chinook salmon O. tshawytscha during their first summer in the northern California Current. Nonmetric multidimensional scaling and cluster analysis of diets by size showed several distinct...

Early Ocean Dispersal Patterns of Columbia River Chinook and Coho Salmon

Creator:

Fisher, J. P., Weitkamp, L. A., Teel, D. J., Hinton, S. A., Orsi, J. A., Farley, E. V., Jr., Morris, J. F. T., Thiess, M. E., Sweeting, R. M., and Trudel, M.

Abstract:

Several evolutionarily significant units (ESUs) of Columbia River basin Chinook Salmon Oncorhynchus tshawytscha and Coho Salmon O. kisutch are listed as threatened or endangered under the U.S. Endangered Species Act. Yet little is known about the spatial and temporal distributions of these ESUs immediately following ocean entry, when year-class success...

Marine distributions of chinook salmon from the West Coast of North America determined by coded wire tag recoveries

Creator:

Weitkamp, Laurie A.

Abstract:

The coded wire tag (CWT) database contains detailed information on millions of Pacific salmon Oncorhynchus spp. released from hatcheries or smolt traps and recovered in the north Pacific Ocean and its tributaries. I used this data set to examine the spatial and temporal variation in the marine distributions of 77...

Buoyancy regulation and barotrauma in two species of nearshore rockfish

Creator:

Parker, Steven J., McElderry, Howard I., Rankin, Polly S., and Hannah, Robert W.

Abstract:

Fishes with closed swim bladders regulate buoyancy during depth changes by secreting and resorbing swim bladder gases. Forced ascent during fishery capture results in barotrauma caused by rapid expansion and exsolution of gases from body fluids. Pressure changes in hyperbaric chambers were used to examine changes in swim bladder integrity...

Effects of juvenile steelhead on juvenile chinook salmon behavior and physiology

Creator:

Kelsey, D. A., Schreck, Carl B., Congleton, J. L., and Davis, L. E.

Abstract:

Experiments were designed to determine whether and how steelhead Oncorhynchus mykiss affect chinook salmon O. tshawytscha when the two species are confined together. In a behavioral experiment, we observed groups of juvenile chinook salmon and steelhead together and groups of chinook salmon alone to determine whether the steelhead were aggressive...

Distribution, Stock Composition and Timing, and Tagging Response of Wild Chinook Salmon Returning to a Large, Free-Flowing River Basin

Creator:

Eiler, John H., Masuda, Michele M., Spencer, Ted R., Driscoll, Richard J., and Schreck, Carl B.

Abstract:

Chinook Salmon Oncorhynchus tshawytscha returns to the Yukon River basin have declined dramatically since the late 1990s, and detailed information on the spawning distribution, stock structure, and stock timing is needed to better manage the run and facilitate conservation efforts. A total of 2,860 fish were radio-tagged in the lower...
