Abstract
    The potentially exploitable deep-water crabs of the family Geryonidae are widely distributed on the continental slopes of the world, at depths of 200-1200m. Presently, only two species are of commercial importance: Chaceon maritae in South West African waters, and C. quinquedensChaceon and Geryon. Given the deep-water distribution at low temperatures, slow growth and maturation rates, and possibly infrequent recruitment of geryonid crabs, it is doubtful if high yields are sustainable. Hence, the choice facing geryonid fishery managers may be between a large open ''boom and bust'' short-term fishery, or a much smaller restricted long-term fishery that hopefully could be sustained. However, more knowledge of geryonid biology and population dynamics is required before any effective management measures can be implemented.
