The burrowing crayfish, Parastacus pugnax (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.
