EFFECTS OF ASCORBIC ACID ON THE INCUBATION OF RAINBOW TROUT IN THE RECIRCULATING AQUACULTURE SYSTEM (RAS)
Studies of ascorbic acid action on the growth and survival of rainbow trout (Oncorhynchus mykiss) are presented in article at incubation in the conditions of fish-breeding industrial complex (RAS). As a result, application of ascorbic acid off concentration of 200 µmol/l (exposure time-15 minutes, before a yolk-sac resorption), provides the significant mass increase by 64%, increase in standard length (SL) by 9,2%, increase in survival by 9,5% and improvement of toxicological parameters in the decade survival analysis of a rainbow trout. Application of this method of enhancing the incubatory process can be useful for the fish-breeding farms which are engaged in the rainbow trout reproduction.
