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。

The effects could be attributed to the selective action of BmK Ⅰ on the TTX-S Na〓 channel: slowing the inactivation process of Na〓 channel, increasing the amplitude of peak Na〓 currents; 2 BmK abT, a new-type neurotoxin with higher sequence homology to β-type scorpion neurotoxin, was found to slow the inactivation process of Na〓 channel and prolong the duration of action potential in DRG neurons.

这些结果提示BmK IT2和BmK AS-1的外周抗伤害性效应可能是通过它们对小直径DRG神经元外周游离末梢即C纤维末梢上的TTX-S和TTX-R钠通道的门控调节所致，且BmK IT2对角叉菜胶致炎大鼠较强的抗伤害性作用可能是由于它对TTX-R钠通道较高的敏感性所致。二。特异性钠通道调制剂-东亚钳蝎神经毒素的电生理特征。
