摘要:
我们于1984年秋至1986年春在胶州湾西部进行了两次海湾扇贝与海带轮养试验;利用同一组养殖筏,夏秋养殖海湾扇贝,冬春养殖海带。1985年平均亩产海带1000kg及海湾扇贝2700kg,盈利3732.6元;1986年平均亩产海带1400kg及海湾扇贝3300kg,盈利4850.7元。轮养能降低养殖成本,从而使胶州湾的海带养殖变亏为盈。

A REPORT ON THE EXPERIMENTAL CULTIVATION OF BAY SCALLOP AND KELP BY TURNS
Abstract:
Two experimental culti vat ions of bay scallop (Argopecten irradians) in summer-autumn and kelp (Laminaria japonica) in winter-spring were conducted in western Jiaozhouwan Bay, Yellow Sea, from late fall, 1984 to early spring, 1986 with the same long-line rafts. The yield of the kelp and the scallop averaged 1000 kg (dried weight) and 2700 kg respectively, netting an average profit of 3736. 2 yuan per mu, in 1985, 1400 kg (dried weight) of kelp and 3300 kg of bay scallop per mu, netting an average profit of 4850.7 yuann in 1986. The cultivation of scallop and kelp by turns will re-duce greatly the investment.
