          Abstract

          La información científica sobre Ucides occidentalis es escasa y parte de estos estudios no han logrado una difusión adecuada, lo cual restringe la disponibilidad de conocimiento sobre esta especie comercial. En este trabajo se revisan diversos estudios sobre U. occidentalis y se presenta información obtenida de observaciones directas realizadas entre 2011-2014 en los manglares del Golfo de Guayaquil, Ecuador. Se muestran notas sobre cambios en la taxonomía de U. occidentalis, sus características biológicas, ecológicas y pesqueras. Se discuten características del interés pesquero como la densidad poblacional y períodos de reproducción. Finalmente, se discute el manejo de las pesquerías de U. occidentalis en el Golfo de Guayaquil debido a que, en los últimos años, se ha evidenciado una disminución en los niveles de desembarques y a la vez, un aumento en la talla media comercial; aquello sugiere que se deben considerar ambos factores en la evaluación del stock, para tener una mejor aproximación sobre el estado poblacional del recurso y sus niveles de explotación.

          Translated abstract

          Scientific information on Ucides occidentalis is scarce, and part of these studies have not adequate diffusion, this situation restricts the availability of knowledge about this commercial species. In this work, on the one hand, diverse studies on U. occidentalis are reviewed, and on the other, information obtained from direct observations made since 2011 to 2014 in the Gulf of Guayaquil mangroves, is presented. Notes on changes in the taxonomy of U. occidentalis, its biology, ecological and fishery characteristics are presented. Characteristics to fishing interest such as density data and reproduction periods are discussed. By last, it is discussed the management of fisheries of U. occidentalis in the Gulf of Guayaquil, because in recent decades, U. occidentalis has evidenced a decrease in the landing levels and at the same time, an increase in the average commercial size; this suggest that both factors should be considered in the evaluation of stock, and thereby to have a better approximation on the population status of the resource.
