Winter Artificial Breeding Technology for Large-Sized Seedlings of Pseudobagrus ussuriensis
Abstract：In recent years, due to changes in the natural ecological environment and human activities, the natural population of Pseudobagrus ussuriensis has been decreasing year by year and has now become a rare fish species. In the market, the supply of this rare fish species is scarce, and its price has risen accordingly, highlighting the urgency and importance of conducting artificial breeding of Pseudobagrus ussuriensis. Especially in the high-cold areas of Heilongjiang, the long winter ice period poses a serious challenge to the overwintering of Pseudobagrus ussuriensis fry. Currently, overwintering technology is not yet mature, leading to low survival rates of fry. In view of this, our research team has not only been deeply exploring the technology of overwintering under ice but has also simultaneously carried out trials on large-scale fry breeding in winter. We have summarized the breeding techniques we have developed, aiming to provide references and insights for farmers with greenhouse farming conditions.
