哑铃湾网箱养殖可持续容量研究

Calculation of sustainable aquaculture capacity of Yaling Gulf

在相关养殖容量研究的基础上,提出了养殖环境容量和可持续养殖容量的概念和内涵。以哑铃湾网箱养殖为例,建立了考虑时间累积效应后的养殖环境容量和考虑了社会、经济和环境综合效益后的可持续养殖容量计算模型。估算了在10年时段内哑铃湾网箱养殖环境容量和可持续养殖容量。结果表明,哑铃湾网箱养殖最优环境容量为每年4.11万箱,可持续养殖容量为每年3.45万箱。

The concept of environmental aquaculture capacity and sustainable aquaculture capacity are presented for studying aquaculture capacity. Considering the cumulative time effect of environmental aquaculture capacity and the social, economical and overall environmental effects of sustainable aquaculture capacity, a simple calculation model is proposed to estimate environmental capacity and sustainable aquaculture capacity of cage culture in Yaling Gulf for the next 10 years. Using relevant data and information essential for the ease, the model estimate of the best environmental capacity of cage culture in Yaling Gulf is 41 100 cages per year and that of the sustainable aquaculture capacity is 34,500 cages per year.
