          Abstract

          El camarón excavador, Parastacuspugnax (Poeppig, 1835), es una de las seis especies de la familia Parastacidae que habita las aguas dulces de Chile, y la que soporta mayor extracción para consumo humano. Sin embargo, carece de una legislación que la proteja y su conocimiento biológico es escaso, fragmentario y disperso. En este artículo se recopila la información publicada de esta especie, junto a otros datos accesibles al autor, con el objetivo de actualizar el conocimiento de su biología, evidenciar la magnitud de la presión extractiva que soporta y analizar la factibilidad de su cultivo en cautiverio. Se proporciona información sobre: sistemática, distribución geográfica, hábitat, conducta excavadora, variación morfológica, casos teratológicos, tamaño, relación longitud-peso, estructura de longitud, densidad poblacional, biología reproductiva, migraciones, hábitos alimentarios, crecimiento, depredadores, epibiontes, parásitos, enfermedades, pesquería y comercialización, legislación, estado de conservación y perspectivas de cultivo.

          Translated abstract

          The burrowing crayfish, Parastacuspugnax (Poeppig, 1835), is one of six species of the family Parastacidae inhabiting the fresh waters of Chile, which supports the greatest extraction effort for human consumption. However, no legislation protects it and its biological knowledge is poor, fragmented and dispersed. This article collects the information published for this species, along with other data available to the author, in order to update the knowledge of its biology, show the extent of extraction pressure that supports, and analyze the feasibility of cultivation in captivity. It provides information on: systematic, geographical distribution, habitat, burrowing behavior, morphological variation, teratological cases, size, length-weight relationship, size structure, population density, reproductive biology, migrations, food habits, growth, predators, epibionts, parasites , diseases, fishery and marketing, legislation, conservation status, and crop prospects.
