Abstract
Six agroecosystems (AES) with an aquaculture component were studied in the State of Veracruz, Mexico. For each particular agroecosystem activity a Modified Policy Analysis Matrix was applied to obtain the Net Income and the WINRM (Wetlands Integrated Natural Resources Management) model was used to estimate the Benefit/Cost ratio (B/C) and the break even point for aquaculture in each agroecosystem. These analyses took into account two different criteria: 1) Including land rent and labor as costs, and 2) Excluding land rent and family labor from the analysis. Results show that depending of the type of producer, certain specific agroecosystems are able to incorporate profitably tilapia production systems. B/C ratio and net profits increase as producer type rises, in accordance with the following scale: Beginner, Artisan, Intermediate and Business.
