Widely distributed in Central America of fresh water and salt waters, the United States for the main freshwater aquaculture species. 1999 U.S. freshwater aquaculture production accounted for about 81 percent of the large warm-water species of fish, fork spots to fish tail as the Ministry of Agriculture to promote the country's fresh water breeding improved varieties have a very obvious advantages: First of Table no scales no small thorn, processing convenience and the other is the quality and refine, nutrient-rich, easy to digest and absorb the third is of miscellaneous eating habits, fast-growing, high yield, strong adaptability and easy to keep the fourth character is tame, like cluster activities , High density of aquaculture, particularly the pond custody and cage culture Fifth Tansi, easy fishing, Youdiao suitable for the development of leisure industry.

广泛分布于美洲中部的淡水和咸水水域，为美国的主要淡水养殖的品种。1999年约占美国淡水养殖总产量的81%，该鱼种是大型温水性淡水鱼类，斑点叉尾回鱼作为农业部向全国推广的淡水养殖的优良品种具有很明显的优点：一是体表无鳞没有小刺，加工方便；二是内质细嫩，营养丰富，容易消化吸收；三是食性杂，生长快，产量高，适应性强，易于饲养；四是性格温顺，喜好集群活动，可以高密度的养殖，特别是池塘主养和网箱养殖；五是贪食，易垂钓，适合发展休闲游钓业。

RESULTS摘要: Under isotonic conditions, no single channel activities were observed in most patches. Hypotonic superfusioninduced cell swelling resulted in the appearance of active channel. Under symmetrical condition, the current induced by hypotonicity showed outward rectification and an unitary conductance of （38.1±2.5）pS.
