METHOD OF SPAWN INCUBATION IN ARTIFICIAL NESTS-INCUBATORS ARRANGED IN RIVERS

摘要

FIELD: agriculture. ^ SUBSTANCE: method consists in artificial fertilisation of spawn at fish breeding plants by a "dry method", in transporting spawn to places of spawning, and in laying spawn into artificial nests-incubators. The artificial nests-incubators with embryos developed to the stage of an "eye" are arranged at open from ice rapids-ripple sections of rivers at the end of March. ^ EFFECT: such process facilitates maintaining viability of spawn at transporting and high percent of larvae hatching. ^ 2 cl
