海底底播增殖是一项投资少、风险小、效益高的生态养殖模式,投入与产出比可达1:6,被誉为“海底银行”工程。辽宁省大连市有200多万亩可增殖海域,发展底播增殖的条件得天独厚。目前该市底播增殖面积已达到90万亩,其中今年新增15万亩。今年收获面积25万亩,收获产量5万吨,产值可达10亿多元。底播增殖的特点:一是品种结构进一步优化,在虾夷扇贝仍为主导品种的情况下,海参、魁蚶、海胆、象拨蚌
Underwater seabed proliferation is a less investment, low risk, high efficiency of the ecological farming model, the input-output ratio of up to 1: 6, known as the “Underwater Bank” project. Dalian, Liaoning Province, more than 200 million mu can proliferate the sea, the proliferation of conditions for the development of endowment blessed. At present, the city has reached 900,000 mu of proliferating area at the end of the year, of which 150,000 acres have been added this year. This year harvest area 250000 mus, harvest yield 50000 tons, the output value amounts to more than 1 billion yuan. Bottom propagation characteristics of proliferation: First, to further optimize the species structure, in the case of shrimp is still the dominant species of scallop, sea cucumber, Kui, sea urchin,
