متن کاملEffect of age on reproductive efficiency of adult rainbow trout, Oncorhynchus mykiss Walbaum, 1972
Rainbow trout, oncorhynchus mykiss is one of the most important cold water fishes in Iran. For successful artificial propagation of rainbow trout, the quality and quantity of brooders and sexual materials are key factors. In the present study, we investigated the age-dependent changes of reproductive efficiency. For this purpose, the brooders were divided into age classes and then three age gro...
متن کاملEffect of sex reversal in rainbow trout (Oncorhynchus mykiss Walbaum) using 17 -methyltestosterone and 11 -hydroxyandrostenedione
The aim of the experiment was to compare the effectiveness of sex reversal in mature female rainbow trout using 17 -methyltestosterone (6 ppm-MT) and 11 -hydroxyandrostenedione (20 ppm-OHA). Hormones were administered with the first exogenous feed for up to 60 days. Among the fish treated with OHA, 95% females were reversed into mature neo-males and 1.6% to bisexual individuals. Among the fish ...

متن کاملTranslocation of viable Aeromonas salmonicida across the intestine of rainbow trout, Oncorhynchus mykiss (Walbaum).
The pathogenic bacterium Aeromonas salmonicida is the causative agent of the destructive disease furunculosis in salmonids. Horizontal transmission in salmonids has been suggested to occur via the skin, gills and/or intestine. Previous reports are contradictory regarding the role of the intestine as a route of infection. The present study therefore investigates the possibility of bacterial tran...
