| contents | An economic analysis of the Heterocarpus reedi and Cervimunida johni fisheries off northern-central Chile, from 1997 to 2000 Eduardo P. Pérez Ciencias de la Tierra Chile economics quasi rent nylon shrimp squat lobster The economic effects resulting from the diminishing catch per unit of effort (CPUE) in the nylon shrimpand squat lobster fishery off northern-central Chile from 1997 to 2000 were evaluated. A bio-technological simulationmodel was used that describes the physical and biological performance variables for the fishery. An economic submodelwas incorporated to the original model in order to perform an integrated analysis of the crustacean fishery, including thecatch and processing sub-sectors. The economic results, in conjunction with the data on catch and stock size, explainedthis fisherys dynamic off northern-central Chile during the study period. The total catch increased 21% between 1997and 2000 and the final production increased 24%, but the quasi rent of the variable costs increased only 11%. The sameperiod saw costs associated with fishing trips increase 117% and the total production cost increased 93%. The study resultsshowed that part of the profits were lost due to the decreased biomass of both resources and the excessive increase inthe average production costs, which were explained by the increased fishing trip costs. In order to obtain a better representationof the fisherys performance, economic references points should be incorporated to complement the traditionalbiological (biomass) and fishery (CPUE, catches) proxies. 2007 artículo científico 0716-1069 https://www.redalyc.org/articulo.oa?id=45635205 en http://www.redalyc.org/revista.oa?id=456 Investigaciones Marinas application/pdf Pontificia Universidad Católica de Valparaíso Investigaciones Marinas (Chile) Num.2 Vol.35 |
