贻贝作为我国较早养殖的贝类品种之一,其养殖面积曾一度占据了浅海养殖的主导地位。随着20世纪90年代以栉孔扇贝为代表的贝类养殖的兴起,大量繁殖的贻贝又成了浅海筏式养殖的一种负担,养殖单位曾想尽一切办法清除养殖筏架上的贻贝,以防影响其它品种的生长。但随着栉孔扇贝大面积死亡情况的发生,贻贝苗种的易附着、生长快、产量高、成本低等优势又显现了出来,再一次成为部分地区的主导养殖品种。2001年日照市东港区的养殖单位创造了每台筏架产贻贝4000 kg,产值2000元的高效益,现将其养殖方法介绍如下:
As one of the earliest species of shellfish cultured in China, mussels occupy the dominant position of shallow-sea breeding once. With the rise of shellfish farming, represented by chlamys farrers, in the 1990s, large-scale breeding of mussels has become a burden on shallow-sea rafts, and farms have tried every means to clear their shelves Shellfish, to prevent the growth of other species. However, with the large-scale death of scallop Chlamys, the advantages of easy attachment, rapid growth, high yield and low cost of mussel seed appeared once again and became the dominant cultured species in some areas once again. In 2001, the breeding unit in Donggang District of Rizhao City created a high efficiency of 4,000 kg of mussels produced per raft, with a production value of 2,000 yuan. The farming methods are described as follows now:
