Flavobacteriosis in Coho Salmon (Oncorhynchus kisutch)

1980
Salmon production in Spain has been increasing during the past years. Geographical areas for these cultures are located in estuaries rich in phytoplankton and Zooplankton in North Spain. Most of the pathological problems are related to diseases already found in other countries. Among them vibriosis and kidney disease stand out (ACUIGRUP, 1977). Special

Primitive Neuroectodermal Neoplasia in Coho Salmon, Oncorhynchus kisutch

Veterinary Pathology, 2004
Twelve coho salmon, approximately 8 weeks old, were each observed to have a single neoplasm involving the dorsolateral axial skeletal musculature. The neoplasm was closely associated with the vertebrae in all cases. The neoplasm was composed of islands containing small cells with round and occasional spindeloid morphology.

Homing of coho salmon (Oncorhynchus kisutch) exposed to morpholine

Aquaculture, 1985
Abstract Smolts of coho salmon ( Oncorhynchus kisutch ) were exposed to 5 × 10 −5 mg·l −1 morpholine for 15 days and released into the Salmon River along with an unexposed control group. During the following two autumns, morpholine was introduced into the hatchery's fish ladder on various days and the return of experimental fish was recorded.

CHARACTERIZATION OF THE OVARIAN PROTEOME IN COHO SALMON (ONCORHYNCHUS KISUTCH)

2023
Considerable gaps exist in understanding the regulation of ovarian development in bony fishes. While much is known about the basic physiology of teleost reproduction during the later stages of oogenesis (process which includes yolk formation, maturation of the ovum, and its release into the ovary), little is known about the transition into puberty.

The multiple hemoglobins of coho salmon : Oncorhynchus kisutch

2011
Studies were conducted to determine the onto genetic changes in the number and relative concentration of the electrophoretically distinguishable hemoglobin polymorphs of coho salmon, Oncorhynchus kisutoh and the influence of certain environmental factors upon the expression of the hemoglobin variants.

Regulation of hepatic growth hormone receptors in coho salmon (Oncorhynchus kisutch)

General and Comparative Endocrinology, 1992
Factors potentially regulating hepatic growth hormone (GH) receptors in coho salmon (Oncorhynchus kisutch) have been investigated. From December to June of the first year, relative changes in hepatic 125I-sGH binding and 35SO4 incorporation by ceratobranchial cartilage were similar.

Effects of ionizing radiation on osmoregulation in fish Oncorhynchus kisutch

Comparative Biochemistry and Physiology, 1965
Abstract 1. 1. Decreased survival occured for juvenile coho salmon following doses of X-radiation ⩾ 1000 r when transferred from hypo-osmotic to a hyperosmotic environment (0%–30% salinity). 2. 2. Survivors which had remained in salt and fresh water 60 days post-irradiation were sacrificed for plasma sodium, chloride and osmotic ...

Development of osmotic and ionic regulation in juvenile coho salmon Oncorhynchus kisutch

Comparative Biochemistry and Physiology, 1966
Abstract 1. 1. The developmental pattern for the osmotic and ionic regulatory system during the juvenile phase of the life cycle was determined. Measurements of survival time were made monthly as were changes in blood osmotic, sodium and chloride concentrations following exposure to sea water ( salinity = 30‰ ). 2. 2. The development of

Smoltification induced by a ‘skeleton’ photoperiod in underyearling coho salmon (Oncorhynchus kisutch)

Fish Physiology and Biochemistry, 1989
Underyearling coho salmon fry were subjected to three initial photoperiod treatments (6L∶18D, 10L∶14D, 14L∶10D) for two months and subsequently to three final treatments (16L∶8D, 9L∶6D∶1L∶8D, 10L∶14D) in a factorial design. Growth rates and seawater adaptability were monitored regularly.

Osmotic regulation in juvenile Oncorhynchus kisutch (Walbaum)?II

Hydrobiologia, 1967
In a previous paper (COCHE, 1967), results concerning the salinity tolerance of coho salmon fry were presented. The present study deals with the ability of yearlings to dispose of the chloride they passively absorb when abruptly transferred from fresh to salt water . Coho salmons normally reside one year in the stream where they were born, the majority
