三都湾网箱鱼类养殖容量的估算

以底质硫化物为指标,采样实地调查估算法,估算福建宁德三都湾网箱鱼类养殖容量。选取的5片网箱养殖区底质硫化物调查结果,每片网箱养殖区底质硫化物的含量从网箱养殖区的中心向边缘递减,网箱养殖区外侧硫化物含量均没有超标;利用SPSS软件的双变量相关性分析功能,分析底质硫化物与单位水体养殖密度之间的相关关系,得到指数增长曲线方程:y=81.858e1.214x,经相关性分析,得到R=0.989,R2=0.977,p0.01(n=6),相关性显著。根据该方程和底质硫化物评价标准,计算得出三都湾网箱适养水域的鱼类养殖容量为1.07kg/m3。

Estimation on the cage culture capacity of fishes of Sandu Bay,Chian

Taken the sediment sulfide as an index,surveying and estimating method in site was used to calculate the cage culture capacity of fish of Sandu Bay in Ningde,Fujian Province.According to the surveying results of sedimental sulfide of 5 cage culturing areas,the sulfide contents of each area were declined from the central areas to the edge.And the sulfide contents from the edge were lower than the standard content;By the correlation analysis of SPSS software,there was a good correlationship between the cage density of fish and the sulfide content.The regression equation was y=81.858e1.214x（R=0.989,R2=0.977,p0.01,n=6）,and the correlation was significant.According to the equation and the standard content of sedimental sulfide,the cage carrying capacity of fish which was expressed as the carrying capacity of fish in a unit cube water in Sandu Bay was 1.07 kg/m3.
