我国内陆海水鱼的人工集约养殖,较之日本、法国、挪威等国,历史较短,规模较小,我国的香港、台湾,也较内陆地区为早。国内的海鱼养殖,过去都以港养方式,纳苗蓄养,品种以鲻科、鲷科、鲈科鱼为主,基本上是自然放养,产量较低。1980年我国开始出现以网箱形式高密度精养鮨科、鲷科、鲈科、鯵科鱼为主。徐绍隆等(1985)进行了网箱养殖试验,取得成功。随着高密度精养,人工投饵带来了各种病害,引起养殖鱼类的大批死亡。以珠海桂山岛为例,1983年底因尖吻鲈发病死亡,镇试验排损失5万多港元;1984年桂山岛已有270多个网箱,10月份连
Artificial intensive farming of inland seawater fish in China is shorter and smaller than Japan, France and Norway. Hong Kong and Taiwan in China are also earlier than inland areas. Domestic marine fish farming, the past are to Hong Kong-style way, satisfied seedlings storage, the species to Trichosanthes, seabream Branch, bass fish-based, basically natural stocking, low yield. In 1980 China began to appear in the form of high-density cages netted in the form of cyprinidae, baeidae, perch, gynostemma based. Xu Shaolong et al (1985) conducted a cage culture experiment, and achieved success. With high-density intensive, artificial feeding has brought a variety of diseases, causing a large number of farmed fish died. Taking Guishan Island in Zhuhai as an example, by the end of 1983, the incidence of death due to bigmouth bass was reduced by more than 50,000 Hong Kong dollars. In 1984, there were over 270 cages in Guishan Island. In October,
