An integrated multi-trophic aquaculture assessment for Pacific oyster (Crassostrea gigas) aquaculture as a bioremediation strategy in areas impacted by fish farm effluents in Rio San Pedro was assessed by combining geographic information system with carrying capacity models. Sites of 0.44 km(2) were evaluated considering constraints; physical factors, growth and survival factors, environmental quality factors, water and sediment quality criteria, factor suitability ranges, and Multi-Criteria Evaluation. Isleta and Flamenco are promising sites for oyster production, and Dorada is of marginal interest. Carbon and nitrogen removal from the water by algae and through detritus filtration was estimated. The biodeposition of organic material from longline leases was found to have little negative impact on sediment. The eutrophication results indicate that phytoplankton removal had a positive impact on water quality at the Dorada. This case study quantified the direct profitability and bioremediative environmental service advantages that fish-shellfish farms can have relative to fish monocultures.
利用地理信息系统与承载能力模型相结合，对受里奥斯安佩德罗（Rio San Pedro）鱼类养殖场废水影响的地区，太平洋牡蛎（Crassostrea gigas）水产养殖的综合多营养层水产养殖评估，评估了 0.44 平方公里的区域，并考虑了限制因素、物理因素、生长和存活因素、环境质量因素、水和沉积物质量标准、因素适宜范围和多标准评估。Isleta 和 Flamenco 是牡蛎生产的有前途的地点，而 Dorada 则是边际利益。藻类和碎屑过滤从水中去除碳和氮，通过底栖生物过滤从水中去除碳和氮。通过延绳钓租约进行的生物沉积有机物质对沉积物的负面影响很小。富营养化结果表明，Dorada 浮游植物的去除对水质有积极影响。本案例研究量化了鱼类-贝类养殖场相对于鱼类单一养殖的直接盈利和生物修复环境服务优势。
