Resumen
Se analizaron 63 muestras de crustáceos decápodos, colectados entre las latitudes 1º18’N y 3º12’S, en el talud continental, entre 500 a 1500 metros de profundidad. Identificándose 44 especies ubicadas así: del Suborden Dendrobranchiata, Superfamilia Penaeoidea 4, del Suborden Pleocyemata están los infraórdenes: Caridea con 18 especies, Astacidea 1, Palinura 3, Anomura 11 y de Brachyura 7. Se elaboró una clave para las familias encontradas; así como, para las especies identificadas. El análisis de los resultados en relación al aspecto zoogeográficos encontramos: 5 especies de la subprovincia de Galápagos presentes en el talud continental como: Aristeus occidentalis, Munida hispida, Lithodes galapagensis, Rochinia cornuta y Tricopeltarium corallinus; dos especies consideradas restringidas para la provincia Perú- Chile como Glyphus marsupialis y Neolithodes diomedeae que amplían su distribución al Golfo de Guayaquil. En relación a las especies de alto potencial económico se encuentran los camarones: Haliporoides diomedeae, Nematocarcinus agassizii, Benthesicymus tanneri y Heterocarpus hostilis, otro de los grupos importantes tanto desde el punto vista alimenticio como económico son los cangrejos litodides como Neolithodes diomedeae, Paralomis papillata y Paralomis otsuae que soportan una pesquería en los países del cono sur. Debido a estos aspectos se recomienda que se continué con este tipo de estudio para conocer nuestra fauna, realizar estudio biológico de las especies para saber si pueden soportar una extracción sin afectar a las poblaciones que por siglos se encuentra en esta área.
We analyzed 63 samples of decapod crustaceans collected between latitudes 1 º 18'N and 3 ° 12'S, on the continental slope, from 500 to 1500 meters deep. Located and identified 44 species: the Dendrobranchiata Suborder, Superfamily Penaeoidea 4 species of Suborder Pleocyemata are the Infraorder: Caridea with 18 species, Astacidea 1, Palinura 3, Anomura 11 and Brachyura 7. A key was developed for families found, as well as for the species identified. The analysis of the results in relation to zoogeographical aspects are: five species of Galapagos sub province present on the continental slope as Aristeus occidentalis, Munida hispida, Lithodes galapagensis, and Tricopeltarium corallinus Rochinia cornuta, two species considered to be restricted to the province Peru- Chile Glyphus marsupialis and Neolithodes diomedeae and expanding their distribution to the Gulf of Guayaquil. In relation to species of high economic potential are the shrimp: Haliporoides diomedeae, Nematocarcinus agassizii, and Heterocarpus hostilis and Benthesicymus tanneri of their size and volume found in this survey, another of the major groups from both nutritional and economic point of view are litodides crabs as Neolithodes diomedeae, Paralomis papillata and Paralomis otsuae that supporting a fishery in the southern cone countries. Because these matters are recommended to continue with this type of study to know our wildlife, conducting biological study of species to know whether they can withstand a removal without affecting populations throughout the centuries in this area.
