浙北地区杂交黄颡鱼(Pelteobagrus vachelli♀×P.fulvidraco♂)一年两茬池塘养殖模式试验

    Study on the hybrid Pelteobagrus(Pelteobagrus vachelli♀×P.fulvidraco♂) cultured in pond twice a year in north Zhejiang Province

    • 摘要: 为了探索浙北地区杂交黄颡鱼(Pelteobagrus vachelli ♀×P.fulvidraco ♂)一年两茬池塘养殖模式的可行性,采用水花苗种一年一茬和大规格苗种一年两茬的养殖模式进行对比试验。结果表明,通过放养较大规格苗种,一年两茬养殖杂交黄颡鱼不仅能提高苗种成活率、出鱼规格,也能缩短养殖周期,还能获得更高的商品价格,以此获取更高的单位效益,进而加快资金回笼,具有较好的经济效益。因此一年两茬养殖杂交黄颡鱼是一种值得在浙北地区推广的养殖模式。

       

      Abstract: In order to explore the feasibility of the culture model of raising hybrid Pelteobagrus (Pelteobagrus vachelli×P.fulvidraco♂) twice a year in pond in north Zhejiang,hybrid Pelteobagrus fry cultured in pond once a year and juvenile cultured in pond twice a year were contrasted.The results showed that hybrid Pelteobagrus juveniled cultured in pond twice a year harvested larger commercial fish with higher survival rate and price.Also,hybrid Pelteobagrus juvenile cultured in pond twice a year could shorten culturing period and quicken the return of funds,obtaining higher unit benefit and economic benefit.Hybrid Pelteobagrus juvenile cultured in pond twice a year was more valuable to be promoted in north Zhejiang Province.
