发展沿海围滩养鱼,利用滩涂资源建立商品鱼基地中遇到的主要问题是当年放养当年不能养成食用鱼。在精养鱼池中用夏花当年养成食用鱼已经成功。而在海涂滩塘中用夏花当年养成食用鱼至今尚未见有先例。围滩养鱼的滩塘环境条件比较恶劣,面积又比较大(一般每框面积达几十公顷),传统都使用大规格鱼种。在传统围滩养鱼中,管理粗放,鱼种、饵料投入少,产量一般都不超过每公顷750公斤,经济效益很低。针对上述问题,我们于1985年开始在江苏省黄海农场试验大面积5000亩围滩用夏花当年养成食用鱼,取得了成功。一、选择已围垦荒滩,拓沟加圩框圩高出田面1.5米。每框面积9公顷左右。
The main problem encountered in the development of coastline beach fish culture and the establishment of commercial fish bases using beach resources was the year when stocking fish could not be cultivated in the year of stocking. In the intensive fish pond with summer flowers to develop food fish has been successful. There is no precedent for the development of edible fish in the Turtle Beach with summer flowers. Beach pond beach environment rather poor, large area (generally each frame area of dozens of hectares), the traditional use of large size fish species. In the traditional perch fish, the extensive management, fish species, less food input, the output does not generally exceed 750 kg per hectare, low economic benefits. In response to the above problems, we started in 1985 in the Yellow Sea Farm in Jiangsu Province to test a large area of 5,000 acres of beach with summer flowers to develop food fish, and achieved success. First, the choice has been reclaimed wasteland, extension ditch plus Wei Xian frame surface above 1.5 meters. Each frame area of about 9 hectares.
