近年来,北美淡水鱼类——斑点美洲鮰(Ictalurus punctatus),作为出色的养殖对象,已在许多国家受到重视。在美国,它已成为南方各州最重要最普及的养殖鱼类,1971年全国养殖面积已达25,000公顷。1972年,苏联由美国引进第一批斑点美洲鮰仔鱼,1975年开始进行繁殖实验,目前,已养殖于图拉省、列宁格勒省、罗斯托夫省等热电站网箱养鱼场,并移植到格鲁吉亚、摩尔达维亚、立陶宛、乌克兰和达格斯坦。斑点美洲鮰的生物学特点及其养殖技术的发展,使之成为引人注目的大有可为的淡水养殖鱼类。
In recent years, Ictalurus punctatus, the North American freshwater fish, has been valued as a good breeding target in many countries. In the United States, it has become the most important and most widely used farmed fish in the southern states. In 1971, the country’s aquaculture area reached 25,000 hectares. In 1972, the Soviet Union introduced the first batch of spotted American jackalfish from the United States and began breeding experiments in 1975. At present, it has been bred in the cage fish tank of thermal power station in Tula province, Leningrad province and Rostov-on -ij Transplant to Georgia, Moldavia, Lithuania, Ukraine and Daghestan. The biological characteristics of the spotted American jackfruit and the development of its farming techniques make it a compelling freshwater cultured fish.
