Abstract: It has been generally stated that deepwater fishes cannot sustain high levels of exploitation because of their characteristic slow growth, longevity and low reproductive output. However deepwater fish species display a wide variety of life-history strategies, occupying diverse positions along the K-r continuum. Literature sources provided data on age, growth, fecundity, maturity and mortality rates of several deepwater teleosts and elasmobranchs. Many teleosts displayed intermediate or conservative life-history characteristics, but the squalid sharks were more stringent K-strategists. These data were used in life-history analyses to assess the sustainability of these mixed-species deepwater fisheries. Whilst there may be scope for compensatory changes in fecundity such scope is likely to be limited, especially for sharks. The implications of these life-history parameters for sustainable exploitation are discussed by way of comparison with continental shelf species from this region.
