METHOD OF GROWING PLANTING STOCK OF STERLET Russian patent published in 2013 - IPC A01K61/00 

Abstract RU 2496311 C1

FIELD: agriculture.

SUBSTANCE: invention relates to fish farming, namely the cultivation of sterlet in installations with a closed cycle of water supply. Four groups of breeders grown from a fry of the same generation are formed. As a result of "spawning" the larvae are obtained in term equally spaced throughout a year-long cycle with an interval of 3 months. The larvae are grown in larval pools. The generations are formed from them, consisting of four groups of fry weighing 1 g. successively produced for the annual cycle. Successive planting of fry of each generation group is carried out in two groups of pools so that the planting date of the next group of generation is three months spaced from the date of the previous one. The fry of each group of generation is grown during the six months to an average weight of 100 g. In the first group of pools the substitution of grown fry of the first group by another group of fry is carried out in the following order: first the first group of generation, then the third group of evenaged generation, then the first group of the subsequent generation etc. In the second group of pools: the second group of generation, then the fourth group of evenaged generation, then the second group of the subsequent generation, etc. At that the time of fry growing start in two groups of pools are three months spaced so that the closure time of growing occur every three months.

EFFECT: increased productivity of growing of planting stock and the uniformity of its production is provided.
