沙蚕是一种潮间带和浅海底栖生物,属于环节动物门多毛纲。它是海水养殖中鱼、虾的理想饵料,有些种类的沙蚕还可以供人类直接食用。由于它含有生物引诱剂,故沙蚕又有“万能钓饵”之称。随着养殖业的发展和世界“钓鱼热”的出现,沙蚕的需要量急剧增加,目前沙蚕的产量远远不能满足市场的需求。因而,解决人工养殖沙蚕的技术也就成了海水养殖业中一个引人注意的问题。
Nereis is an intertidal zone and shallow benthic habitat, belongs to the section of the door phylogenetic polygamy. It is the ideal bait for fish and shrimp in mariculture, and some species of Nereis can also be consumed directly by humans. Because it contains a biological attractant, so there is a nematode “universal fishing bait,” said. With the development of aquaculture and the emergence of “fishing fever” in the world, the demand of sandworm has sharply increased. At present, the production of sandworm far can not meet the needs of the market. Therefore, the solution to the artificial breeding of silkworm has also become an attractive problem in the marine aquaculture industry.
