FIELD: pisciculture. ^ SUBSTANCE: the present innovation deals with fishing roe-bearing females, their transportation, keeping them in closed system of water reservoirs under optimal conditions before larvae appearance followed by growing larvae, glaucotoe and fry of stage I. Larvae growing should be performed in reservoirs of vertical conic type at lower water supply in ascending flow at water expenses of not less than 4.8-9.6 l/h/1000 larvae and at special feeding. Glaucotoe growing should be performed at water expenses of not less than 9.6-19.2 l/h and at endogenic nutrition, and fry growing of stage I - at water expenses of not less than 48 l/h in reservoirs of horizontal type. The present innovation provides optimization of fry keeping and decreased fodder expenses. ^ EFFECT: higher efficiency of reproduction. ^ 1 cl, 2 ex |
