PARENTAL BODY WEIGHT AND PROGENY PERFORMANCE IN RAINBOW TROUT (Oncorhynchus mykiss Wall.)

Abstract

The influence of parental body weight on the progeny growth up to the market size was analysed in rainbow trout. The only one and highly significant correlation was observed between female size and amount of eggs (r=0.8). Male size had no influence on the progeny growth. Basing on these results no particular strategy for selecting spawners in mass selection can be recomended.
