鲮鱼(Cirrhina molitorclla)是华南特有的池塘养殖鱼类,广东佛山地区鲮鱼的产量约占淡水鱼的二分之一,在淡水养殖业中占有重要的地位。近年来,随着淡水鱼类人工繁殖技术的进展,鲮鱼的繁殖工作也已开展并获得一定成绩。但关于鲮鱼繁殖生物学上许多基本资料尚未掌握,因此有必要作一次对池养鲮鱼性腺周年变化的研究。充分了解性腺的周年变化,无疑对于人工催情工作是十分重要的。 国内有关淡水养殖鱼类性腺变化的研究,近年来陆续发表的有:鲢、鳙、草鱼、青鱼等(武汉大学、中 Cirrhina molitorclla is a kind of pond culture fish endemic to South China. The production of anchovy in Foshan, Guangdong Province accounts for about one half of that of freshwater fish, and plays an important role in freshwater aquaculture. In recent years, with the progress of artificial breeding of freshwater fish, the breeding of catfish has also been carried out and some achievements have been made. However, many basic information on bream reproduction biology have not yet been mastered, so it is necessary to make a study on the annual changes of gonads in pond catfish. Fully aware of the annual changes in gonads, no doubt for artificial aphrodisiac work is very important. Domestic researches on gonadal changes in freshwater cultured fish have been published successively in recent years: silver carp, bighead carp, grass carp and herring (Wuhan University,
