江黄颡鱼,又称瓦氏黄颡(Pelteebagrus vachelli Richardson),隶属于鲇形目,鲿科,黄颡鱼属,是黄颡鱼属中个体最大、生长速度最快的鱼类,二龄鱼体重可达300~600 g,最大个体达1500 g。该鱼由于肉质细嫩、味道鲜美、无鱼腥味和肌间刺,而深受广大消费者青睐。江黄颡原生活在天然水域的流水环境中,但由于近年来随着天然水域环境的恶化和捕捞强度的加大,江黄颡的自然资源量越来越少。为满足广大消费者对江黄颡商品鱼的需求,我们进行了用不同面积的静水池塘养殖江黄颡成鱼的试验,并获得了成功,现将技术要点总结如下,以供广大同行参考借鉴。
Pelteobagrus vachelli Richardson (Pelteebagrus vachelli Richardson), belonging to the order of the clade, clam, yellow catfish, is the largest individual, the fastest growing fish, the second age Fish weight up to 300 ~ 600 g, the largest individual up to 1500 g.
