蟾胡子鲶(Clarias batrachus)是泰国主要食用淡水鱼类。与我国的胡子鲶(Clarias fuscus)形态和习性相近,但体型较大,生长较快,而肉味稍逊,耐寒力偏弱。在泰国,每年可养殖两次,单位面积产量很高,平均每年每平方米面积产20.9公斤。1978年6月泰国ADK养鱼公司泰籍华裔蔡先生赠送给我所一批蟾胡子鲶鱼苗,规格0.6克左右。为了大力发展蟾胡子鲶的养殖,作者1979年模拟蟾胡子鲶的繁殖生态环境进行了自然繁殖的研究,初步获得成功。现把研究情况简介如下。
Clarias batrachus is Thailand’s main edible freshwater fish. Similar to the morphology and habit of Clarias fuscus in China, but its body size is larger, its growth is faster, its meat taste less and cold resistance is weaker. In Thailand, it can be bred twice a year with high yields per unit area, yielding an average of 20.9 kilograms per square meter of land per year. June 1978 Thai Thai ADK fish company Chinese Tsai presented to me a group of toad beard catfish fry, specifications about 0.6 grams. In order to vigorously develop the growth of Toadstool catfish, the author simulated the natural reproduction of Toadstool catfish in 1979 and made initial success. Now the research situation is as follows.
