Abstract
The paper presents the results of an aquarium experiment on feeding the fry of rainbow trout (Salma gairdneri f. kamloops) with pellets containing different doses of rapeseed oil meal obtained from doubly improved rape variety "Jantar". It was found that the optimal content of rapeseed oil meal was 10%. Taking into account rapid growth and high survival of the fish fed pellets containing higher percentage of rapeseed oil meal, it was stated that its content might be as high as 18%.
