摘    要:对桑沟湾大规模开展增养殖前后的水文环境作了研究。由于大面积高密度养殖,桑沟湾的水动力状况和10年前相比发生了明显变化,潮流速度减缓了50%,水交换率降低了1.7%,海湾海水半交换周期延长了11个潮周期。营养物质输送和海水自净能力受到严重影响。部分养殖品种产量下降,表明养殖容纳量已达饱和状态。和其他海湾相比,桑沟湾的水交换条件还是比较好的,只要科学合理地设置养殖品种和养殖密度,仍不失为一个重要的增养

关 键 词:水文环境  水产增养殖  桑沟湾

Abstract:The hydro-environment in Sanggou Bay now and before large-scale and high density culture are discussed in this paper. Because of the large-area and high-density culture,the hydro-environment in Sanggou Bay changed remarkably compared with that ten years before. The tidal current speed decreased 50%,the seawater exchange rate decreased 1.7% and the seawater half-exchange period was prolonged to 11 tidal periods. Study of aquaculture carrying capacity is necessary and urgent.
Keywords:Hydro-envoronment Aquaculture  Sanggou Bay
