Success in aquaculture depends on the mass production and quality of juveniles. However, many fish species suffered high losses during the early stages of development. Therefore, in order to decrease mortality, produce a large number of healthy larvae is a fundamental issue. On the other hand, one of the micronutrients that can be effective in larvae health is ascorbic acid. During the embryonic and larval periods, this vitamin causes accelerate growth, stress resistance and improving incubation performance. But the ability to synthesize this vitamin does not exist in many fishes and it must enterthe fish body through another ways. Therefore, finding new methods such as enrichment can lead to an increasee in the concentration of this vitamin in gonads and fish eggs and consequently more successful reproduction. Accordingly, the present study investigated how to enrich fish eggs with ascorbic acid and the effects of enrichment on improving the reproduction process and reducing stress in fishes.
