Abstract

Rearing conditions that prevent fish from experiencing their natural reproductive environment disrupt the release of gonadotropins, leading to difficulties in natural spawning and spermiation. To overcome these issues challenges, artificial stimulants are commonly used to induce artificial propagation. Currently, sturgeon hatchery centers in the country utilize dry pituitary extract when hormone therapy is necessary. In many cases, they also employ various brands of gonadotropin-releasing hormone analogues, most of which are imported. Given the needs of the country's fisheries industry and the fact that the hormones required for artificial reproduction are currently imported, a research project was designed and implemented to synthesize an effective gonadotropin-releasing hormone analogue for sturgeon reproduction and compare its performance with common commercial hormones available on the market by the International Sturgeon Research Institute researchers. After confirming the purity and the sequence of the synthesized peptide, the evaluation of the peptide hormone is conducted on Sterlet breeding. The results of this study showed that the use of the synthetic analogue led to a quantitative improvement in sturgeon reproduction.
