Immune responses of ectothermic animals are known to vary seasonally. A loss of sensitivity to cortisol and testosterone (both normally immunosuppressive) in leucocytes from juvenile salmonids during winter has been previously documented. In an attem

Adult spring chinook salmon (Oncorhynchus tshawytscha) elaborate high plasma concentrations of testosterone during sexual maturation, and these levels of testosterone have been shown to reduce the salmonid immune response in vitro. Our search for the

The immune –endocrine responses in spring chinook salmon ( Oncorhynchus tshawytscha ) were examined during their freshwater migration and final maturation. In 1990, migrating fish had high plasma cortisol titres (means 200 ng ml −1 ) and generate

Leukocytes from spleen and anterior kidney of both juvenile chinook salmon ( Oncorhynchus tshawytscha ) and rainbow trout ( O. mykiss ) demonstrated specific binding of 3 H-testosterone and the synthetic androgen 3 H-mibolerone. Saturation analysis o

The potential for accelerating final maturation and ovulation/spermiation of adult sockeye salmon (Oncorhynchus nerka) by using gonadotropin-releasing hormone analog (des-Gly10 [D-Ala6] GnRH-ethylamide; GnRHa) was evaluated. GnRHa injection reduced t

Plasma testosterone concentrations were low through the spring and early summer, concentrations began rising in late July and reached maximum levels by ovulation in September. Plasma concentrations of 11-ketotestosterone were low throughout sexual ma

We examined the effects of the high concentrations of sex steroid hormones detected in the plasma of sexually maturing chinook salmon (Oncorhynchus tshawytscha) on the functioning of the immune system. Leukocytes from the anterior kidney of juvenile

Cytosol of rainbow trout (Oncorhynchus mykiss) leukocytes demonstrated specific and saturable binding of [3H]testosterone (Kd = 0.99 +/- 0.17 nM and Bmax = 30.4 +/- 4.9 fmol/mg protein; based on a total of 6 determinations from three different cytoso
The objective of this research was to examine in detail the migration of juvenile spring chinook salmon (Oncorhynchus tshawytscha) in the Willamette River, Oregon. The authors wanted to determine characteristics of seaward migration of spring chinook

These studies investigated brains of skate, Raja erinacea (order Rajiformes, class Chondrichthyes), for gonadotropin-releasing hormone (GnRH) peptides by chromatography and immunoreactivity with region-specific antisera raised against mammalian GnRH
