Abstract:

In Tai'erzhuang District National Aquatic Germplasm Resources Reserve of Pelteobagrus Fulvidraco, the catch was obtained by setting up three multi-mesh compound gill nets and setting series cage pots, and the data of the catch were measured and analyzed. The present composition of fish, dominant species, biodiversity and the stock of yellow catfish (Pelteobagrus Fulvidraco) were investigated. A total of 22 species, belonging to 5 orders and 9 families, were detected, of which 14 species (64%) were cyprinoid, one species (4%) catfish and one species of herring (4%), three species of perch (14%) and three species of crustaceans (14%). For the protected species Pelteobagrus Fulvidraco, the total DNA was extracted by column genomic DNA extraction kit. The results show that the population structure is stable and the genetic diversity is at a high level, the wild germplasm resources are in good condition. This finding confirms that the biodiversity within the reserve is effectively maintained, and that positive outcomes have been achieved in the conservation efforts of pelteobagrus fulvidraco.
