摘　　要：Mariculture has been one of the fastest-growing global food production sectors over the past three decades.With the congestion of space and deterioration of the environment in coastal regions,offshore aquaculture has gained increasing attention.Atlantic salmon(Salmo salar)and rainbow trout(Oncorhynchus mykiss)are two important aquaculture species and contribute to 6.1%of world aquaculture production of finfish.In the present study,we established species distribution models(SDMs)to identify the potential areas for offshore aquaculture of these two cold-water fish species considering the mesoscale spatio-temporal thermal heterogeneity of the Yellow Sea.The values of the area under the curve(AUC)and the true skill statistic(TSS)showed good model performance.The suitability index(SI),which was used in this study to quantitatively assess potential offshore aquaculture sites,was highly dynamic at the surface water layer.However,high SI values occurred throughout the year at deeper water layers.The potential aquaculture areas for S.salar and O.mykiss in the Yellow Sea were estimated as 52,270±3275(95%confidence interval,CI)and 146,831±15,023 km^(2),respectively.Our results highlighted the use of SDMs in identifying potential aquaculture areas based on environmental variables.Considering the thermal heterogeneity of the environment,this study suggested that offshore aquaculture for Atlantic salmon and rainbow trout was feasible in the Yellow Sea by adopting new technologies(e.g.,sinking cages into deep water)to avoid damage from high temperatures in summer.
