革胡子鲶属鲤形目,胡子鲶科鱼类,近年来在各地大量养殖。它具有食性广、生长快、产量高、肉质鲜美、病害少、耐低氧特点,特别适宜农村房前屋后污水塘养殖,是农村养鱼业的一个好品种。我区气候寒冷,革胡子鲶是否适应山区养殖,作为一个科研课题,我县鱼种场于1988年引进埃及胡子鲶种苗3万尾(规格3厘米),历经几年的保种养殖,均获得很好的经济效益。在成鱼池单养亩产超过1.5吨,同时每年生产苗种100多万尾,为本地区养鱼业提供了新品种,近年来还远销贵州省及湘西自治洲等地。能否保证革胡子鲶安全越冬,度过寒冷季节,是全部养殖过程的关键。1988—1990年3月底,利用县电厂排放的余热水进行越冬保种,水温保持在革胡子鲶的适宜温度,为革胡子鲶选择了安全的越冬场所。1990年3月30日,县电厂因机组改建停电一个月(改用柘溪水电),余热水排放完全中断,4月1日池内温度由22℃下降到 Cats mustard genus leather carp, bearded catfish family, in recent years a large number of aquaculture. It has a wide range of feeding, fast growth, high yield, delicious meat, less disease, hypoxia tolerance, especially suitable for rural housing before the sewage pond breeding, is a good breed of fish farming industry in rural areas. As a research topic, my county fish farm introduced 30,000 species of Egyptian mustard catfish (3 cm in specification) in 1988. After years of conservation farming, Get good economic benefits. In the fishpond single-acre more than 1.5 tons, while annual production of more than 100 million seedlings, fish farming in the region provides a new breed of fish in recent years has also been exported to Guizhou Province and Autonomous Prefecture in western Hunan and other places. Can guarantee the safety of leather catfish wintering winter, through the cold season, is the key to all breeding process. From 1988 to the end of March 1990, surplus water from the county power plant was used for overwintering to conserve water. The temperature of the water was kept at the appropriate temperature of the catfish, and a safe wintering site was chosen for the catfish. On March 30, 1990, the county power plant was shut down for one month due to the rebuilding of the unit (switching to Taixi Hydropower), and the discharge of residual heat water was completely interrupted. On April 1, the temperature in the pool dropped from 22 ℃ to
