Abstract
A series of research works was carried out on the development of biotechnics for rearing young crayfish in artificial conditions to the age of one year(O+). It was established that the nutritional index has a minimum value at the temperature of 17°C (4.5%) and a maximum value at 27°C (7.3%). Nutritional index values also vary with age and in relation to the phases of every subsequent molt. It is preferable that young crayfish be used as seed after the first molt(counting from the end of metamorphosis) and that up to this time they be kept in seperate tanks and provided with enough food.
