山区的特点是山多水少,尤其是能供养鱼的水面就更少。但随着山区一座座小水电站的兴建,为山区发展水产养殖提供新的场所。然而由于种种原因,大多数库坝不是让水白白流失就是粗放养殖,收效甚微。笔者1992年在龙山县湾塘电站库区开展网箱养鱼试点,16只28m~2成鱼箱总产鲜鱼8270kg,箱平产鱼517kg,其中草鱼箱箱平产鱼583kg,最高640kg;鲤鱼箱箱平产鱼465kg,最高605kg。1993年,全县网箱养鱼已发展了50余只。龙山县的实践证明山区发展网箱养鱼是利用水库、
The mountainous area is characterized by less mountainous water and, in particular, less water surface. However, with the construction of a small hydropower station in the mountains, it will provide a new place for the development of aquaculture in mountainous areas. However, due to various reasons, most reservoir dams are not extensive aquaculture, with little success. In 1992, the pilot trial of fishnet cage culture was carried out at Longtang Wantang Power Station. 16 fish from 28m ~ 2% fish tank produced 8270kg fresh fish, 517kg fish from flat box, of which 583kg flat fish from grass carp tank were the highest, 640kg; Carp box flat fish 465kg, up to 605kg. In 1993, the county cage fish has been developed more than 50 only. Longshan County practice shows that the development of mountain cage fish is the use of reservoirs,
