The shrimp fishery in the Gulf of California, México, has raised economical, biological, and environmental concerns that moves interests to develop an efficient, rent earning, and ecologically friendly shrimp fishing fleet in that Gulf. To develop a better understanding of the management of this fishery and its technical efficiency, we examine the producing behavior of the shrimp fishing fleet of San Felipe, B.C. during the 1990-93 time period. We pose a flexible, unrestricted, frontier of production function as a benchmark relative to which we estimate the technical efficiency values of the individual vessels. Our results indicate that the average technical efficiency for the examined shrimp fishing fleet is 80%, a technical efficiency value close to the best use the producing technology given factors. Aging boats were less efficient than newer ones, an expected result, however the cooperative size, as a proxy variable of quality of management, tends to favor the technical efficiency of vessels masquerading the age effect and promoting economies of scale among them. Additionally, our results suggest that cumulative knowledge on this fishery prone efficiency among the examined shrimp fishing vessels, while technical change has been scarce except for the turtle excluders incorporated in the fishing technology during 1996. As concluding remarks we pose that knowledge and fishing abilities, as disembodied shift variables, most be promoted among producers to prone their individual technical efficiency. Similarly, quality of management must be procured to favor economies of scale. We also argue that as long as the examined boats and the rest of shrimp fishing fleet in the Gulf of California, are technologically similar, our empirically oriented productivity analysis enlightens some basic issues to consider in the arrangement and future development of the last one.
