Clearance of plasma cortisol in coho salmon, Oncorhynchus kisutch, at various stages of smoltification

Creator:: Patino, Reynaldo
Abstract:: The metabolic clearance rate (MCR) of plasma radioactivity after a single intracardial injection of ³H-cortisol was elevated during the Spring in yearling coho salmon, Oncorhynchus kisutch. The reasons for this increase in MCR are not clear, but graphical analysis suggested that there may be a seasonal correlation between MCR and...

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...

Effects of inbreeding Coho salmon (oncorhynchus kisutch)

Creator:: Solazzi, M. F. (Mario Frank)
Abstract:: Effects of inbreeding coho salmon (Oncorhynchus kisutch) on survival during early life history, growth, feed efficiency, and resistance to gas bubble disease were studied. No effect of inbreeding could be associated with either F=0.25 or F=0.125. Tetraploidy may help explain the absence of inbreeding depression at these levels.

Factors affecting coho salmon production in Oregon

Creator:: Scarnecchia, Dennis Leslie
Abstract:: Eight scale characters of known hatchery and wild coho salmon (Oncorhynchus kisutch) were compared, and a linear discriminant function was used to determine if hatchery and wild adult coho salmon could be correctly identified by their scales. Eighty-two percent of the hatchery and 89% of the wild fish were correctly...

Factors affecting the smolt yield of Coho salmon (Oncorhynchus kisutch) in three Oregon streams

Creator:: Knight, Ned J.
Abstract:: Data from the coho salmon migration were examined from three streams of the Alsea Watershed Study, conducted on tributaries to Drift Creek, Oregon, from 1959 through 1973. With the migration season defined as November 1 through May 31, the mean seasonal smolt count was 2022 fish in Deer Creek, 665...

Growth and food consumption of juvenile coho salmon exposed to natural and elevated fluctuating temperatures

Creator:: Everson, Larry B.
Abstract:: The growth and food consumption of juvenile coho salmon [Oncorhynchus kisutch (Walbaum)] exposed to natural and elevated fluctuating temperatures were studied in the laboratory with wild fish collected from a salmonid rearing stream. Control temperatures were similar to the temperature regime of a natural stream and the elevated temperatures were...

Hormonal and osmoregulatory aspects of smoltification in coho salmon, Oncorhynchus kisutch

Creator:: Specker, Jennifer Lee
Abstract:: Coho salmon smolts (Oncorhynchus kisutch) were transported at low and high densities. (12 and 120 g/L) for short and long periods (4 and 12 h). Because smolts can be transplanted directly to seawater, half of the fish in each treatment were transported to tanks containing seawater and half to tanks...

Stress, osmoregulation, and the hormone cortisol in yearling coho salmon, Oncorhynchus kisutch

Creator:: Redding, Joseph Michael
Abstract:: Freshwater (FW) and seawater (SW) acclimated yearling coho salmon, Oncorhynchus kisutch, were subjected to severe confinement stress in FW, SW, or a medium (1/3 SW) that was approximately isosmotic to the fish's blood. Chronic stress caused osmotic imbalances in FW and SW, but not in 1/3 SW. In SW, blood...
