The article discusses prospects for use of the theory of adaptogens in demand in medicine and in the fish breeding practice. The obtained results show that the adaptogens use at the early stages of catfish ontogenesis (Clarias Gariepinus, Burchell 1822) can cause the condition of nonspecific increased resistance and expand the adaptive flexibility range of this specie. Adaptogen trekrezan used in our experiments (Oxyethylammonium methylphenoxiacetate) is a synthetic analogue of the natural ginseng. Its application in the embryo culture process has shown positive results. It has reduced the level of the developmental anomaly, increased the first stage larvae hatching and their viability, significantly decreased the mortality rate and reduced the level of cannibalism common for catfish larvae. We have determined that the larvae breeding in the trekrezan medium has considerably increased their growth rate, and weight gain. The obtained results are new, and the adaptogens use at the early stages of ontogenesis in industrial catfish aquaculture is recommended. The Russian Foundation for Basic Research has supported our study with the grant No. 18-416-730005.
