黄颡鱼(Pelteobagrus fulvidraco),俗称嘎鱼、黄辣丁,是近年来深受全国养殖同行和消费者喜爱的水产品,其特点是:肉质细嫩、肉味鲜美、营养丰富、耐低氧、抗严寒,经驯化的鱼苗不互相残食且食用人工配合饲料。该鱼一般生长到50～150g即可作为商品鱼,市场价格较高,需求量日益增大。为进一步研究黄颡鱼精养技术,蓟县水产技术推广站分别于1999年和2001年由华中农大水科院苗种基地引黄颡鱼乌仔3万尾和4.5万尾进行小型精养试验,2001年春季及秋末收获商品鱼,取得了一定的经济效益。现将试验情况介绍如下:
Yellow Pelican (Pelteobagrus fulvidraco), commonly known as Ga fish, yellow spicy Ding, is popular in recent years by breeding counterparts and consumers favorite aquatic products, which are characterized by: tender meat, meat, nutritious, resistant to hypoxia, Anti-cold, domesticated fry do not eat each other and eat artificial feed. The fish generally grow to 50 ~ 150g can be used as commercial fish, the market price is higher, the demand is increasing. In order to further study the cultivation technology of yellow catfish, Jixian Aquaculture Technology Extension Station conducted small-scale intensive cultivation experiments in 1999 and 2001 respectively with 30,000 and 45,000 tails of Ulva Chrysanthemum from the Seed Base of Huazhong Agricultural University Hydrology Branch, In the spring and autumn of 2001, the commercial fish was harvested and achieved certain economic benefits. Now the test situation is as follows:
