Abstract Integrated aquaculture systems have the potential to enhance the environmental sustainability of aquaculture production, if economically feasible. Data from integrated tilapia-prawn production trials were used to develop economic-engineering enterprise budgets for ponds with and without substrate that targeted two different types of markets, using two production scales and two forms of land tenure. Inclusion of substrate increased investment and fixed costs and decreased net returns. Recreational markets (live tilapia for fee fishing and live prawns as bait) were profitable, but sales to supermarkets were not. Production scale and land tenure affected economic outcomes with increased pond size and leasing ponds demonstrating greater profitability. Results provide evidence of the need to carefully evaluate economic trade-offs associated with varying commercial-scale applications to increase the likelihood of adoption of new technologies.

目标市场、生产规模和土地所有权的选择对罗非鱼虾综合生产经济性的影响

摘要 如果经济上可行，综合水产养殖系统有可能提高水产养殖生产的环境可持续性。来自罗非鱼-虾综合生产试验的数据用于制定针对两种不同类型市场、使用两种生产规模和两种土地所有权形式的有基质和无基质池塘的经济工程企业预算。包括底物增加了投资和固定成本并减少了净回报。休闲市场（用于收费捕鱼的活罗非鱼和作为诱饵的活虾）是有利可图的，但对超市的销售则不然。生产规模和土地使用权影响了经济成果，增加了池塘规模，租赁池塘表现出更高的盈利能力。
