Sockeye salmon Oncorhynchus nerka sperm maintained high fertility for 10 s after being exposed to water but fertility dropped sharply after that. Eggs also showed limited longevity after being immersed in water, with a large drop in fertility occurri

Previous studies have shown that spermiating male rainbow trout respond to the presence of female urine in the water with significant increases in plasma levels of gonadotrophin II, 17,20β-dihydroxy-4-pregnen-3-one (17,20β-P) and testosterone. The

Dynamics of excretion of 17alpha,20beta-dihydroxy-4-pregnen-3-one 20-sulphate, and of the glucuronides of testosterone and 17beta-oestradiol, by urine of reproductively mature male and female rainbow trout (Oncorhynchus myklss)

Levels of sulphated 17α20β-dihydroxy-4-pregnen-3-one (17,20β-P; the oocyte maturation inducing steroid) in blood plasmas of sexually mature male and female rainbow trout Oncorhynchus mykiss, were very low in comparison to those of the free steroid

Dans cette étude, nous avons analysé le rôle des stimuli sociaux responsables de l'accroissement des hormones plasmatiques et de la possibilité de libération de semence chez le mâle de la Truite arc-en-ciel. Les mâles étaient placés dans cin
