资兴市杨洞水库位于八面山下海拔830米的高寒山区,是一座以灌溉为主,结合发电、养鱼防洪等综合经营的中型水利工程。特别是在水库养鱼方面,过去主要是靠从衡阳购进大批鱼种,由于水质关系的影响,成活率很低、经济效益不高。为了解决水库投放自给,必须充分利用当地水体生产潜力,克服山区自然条件差的困难,靠山塘来培育大规格鱼种下库,突破18厘米这一规格关。今年在这一方面取得了一定成效,通过0.4南和0.2亩山塘的放养试验;夏花定塘后,经过三个月的培育,鲢鱼达18.2厘米,鳙鱼达17.5厘米,草鱼达23厘米,鲤鱼250—270克,共计7200尾鱼种,经济效益在1850元以上,创造了我单位历史以来的最高产量,最好效益,现将养鱼
The Yangdong Reservoir in Zixing City is located in alpine mountainous area 830 meters above sea level under the mountainous area of Bamian. It is a medium-sized water conservancy project that integrates power generation, fish and flood control and other integrated management. In particular, in the area of fish culture in the reservoir, a large number of fish species were mainly purchased from Hengyang in the past. Due to the impact of water quality, the survival rate is very low and the economic benefits are not high. In order to solve the reservoir self-sufficiency, we must make full use of the potential of local water bodies to overcome the difficulties of poor natural conditions in mountainous areas. This year in this area has achieved some success, through the 0.4 South and 0.2 acres of ponds stocking test; Xia Hua Ding Tong, after three months of cultivation, silver carp up to 18.2 cm, catfish up to 17.5 cm, 23 grass carp Centimeter, carp 250-270 grams, a total of 7200 kinds of fish species, the economic benefits of 1850 yuan or more, to create the highest yield since my unit history, the best benefits, now the fish
