过去由于受重捕轻养观念的束缚,致使近海渔业资源严重衰退。随着产业结构的调整,特别是,海洋“蓝色产业”革命的兴起,海洋渔业生产由过去的重捕轻养,转变为捕养结合,综合发展。海水养殖在海洋渔业生产中的位置就显得愈加突出。养殖规模的不断扩大,养殖品种和养殖方式亦出现了很大的变化,养殖水域也由7～8m等深线向10m以上等深线的海域延伸,这样就产生了捕养的矛盾。
In the past due to be restrained by the concept of re-capture of light support, resulting in a serious decline in offshore fishing resources. With the readjustment of the industrial structure, especially the rise of the “Blue Industry” revolution in the oceans, the production of marine fisheries has shifted from being recaptured and reared lightly in the past to becoming an integrated and integrated development. The position of marine aquaculture in marine fishery production becomes even more prominent. Breeding scale continues to expand, breeding species and farming methods have also undergone great changes, aquaculture waters from the 7 ~ 8m isobath depth of more than 10m isobath extension of the sea, resulting in the contradiction of the capture.
