Descripción:Caño Negro Wildlife Mixed Refuge is located between the counties of Guatuso and Los Chiles in Alajuela, Costa Rica. This wetland has an abundant Pleco fish invasion that damages the native ecosystem, which causes socioeconomic consequences to its citizens. This research objective is to evaluate the technical and financial feasibility of an alternative invasive species use for economic exploitation from an academic perspective. Surveys, secondary data analysis, fieldwork, and expert interview research strategies were applied. It was determined that the most feasible alternative is the production of fish flour for bovine animals fattening. The project has a strong technical and financial justification that supports its feasibility; and the financial study reveals an internal rate of return of 2%, as well as, present value of income ¢ 35 729 676, in addition to the employment. However, the legal component slows its implementation in the short term hence this practice is only authorized in continental waters. This type of fishing is only allowed when done with fishing rods or ropes, but cannot be caught with these; therefore, the current law needs a revision. This research study built a baseline methodology for future profitable projects evaluation analysis aiming to generate economic exploitation of diverse flora and fauna species whose populations need to be controlled due to its negative effect on local ecosystems.
