二龙山水库可养鱼水面10800亩,现有鱼池260亩。历年来鱼种生产方式是5月末6月初鱼苗下池,7月上旬夏花分塘到秋季培育成10厘米规格鱼种投库。为了充分利用5—7月上旬部分空闲鱼池的生产潜力,同时改以前的春秋放养为夏放养,提高投库鱼种成活率。1988年,我们根据当地气候特点,选择了77亩鱼池进行一年两茬鱼种培育试验,当年取得亩产鱼种308.6公斤的好成绩。现将情况 Erlongshan Reservoir fish water can be 10800 acres, 260 acres of existing fish ponds. Over the years the production of fish species is the end of May early fry the next pool, early July summer flowers sub-ponds to cultivate 10 cm into the fall of species of fish cast. In order to make full use of the production potential of some free fish ponds in early May-July, meanwhile, change the previous spring and autumn stocking for summer stocking and improve the survival rate of the cast-stock fish species. In 1988, according to the local climate characteristics, we selected 77 mu of fish ponds to carry out the breeding experiment of two stubble species each year. In the same year, we achieved a good result of 308.6 kg per mu. Now the situation
