根据2001年11月1～10日在舟山蛏子港进行水文调查所获取的水深、海流、盐度、悬浮体等资料,对蛏子港深水网箱养殖的环境条件进行了分析,结果表明:该港海区海水平均流速为35.1～100cm/s的出现频率占56%～84%,表、底层盐度平均值为25.227～26.045,悬浮体含量为0.1～0.399kg/m3的出现频率达92%;港区有多个口门与外海相通,海域水体交换活跃。另外,该港的水深和避风条件也基本符合深水网箱养殖的要求,是一个比较适合于海水鱼深水网箱养殖的基地。
According to the water depth, current, salinity and suspension obtained from the hydrological survey carried out in Bangzi Port of Zhoushan from November 1 to November 1, 2001, the environmental conditions of deep-water cage culture in Bangzi Harbor were analyzed. The results showed that: The average frequency of seawater in the sea area is 35% ~ 100cm / s and the occurrence frequency is 56% ~ 84%. The average salinity of surface and bottom sediments is 25.227 ~ 26.045, and the content of suspended solids is 0.1 ~ 0.399kg / m3. There are multiple port area with the open sea, sea water exchange active. In addition, the port’s water depth and sheltered conditions are also basically in line with the requirements of deep-water cage culture, is a more suitable for deep-sea fish cage culture base.
