Small-scale distribution, life cycle and secondary production of Cumopsis goodsir in Creixell Beach (western Mediterranean)

摘要: The cumacean Cumopsis goodsir (Crustacea: Peracarida) was sampled monthly in 1991-1992 the surf zone of Creixell Beach (north-western Mediterranean), to describe its life history and secondary production. In this unstable coastal soft-bottom area, C. is one dominant species subtidal community. annual mean density population 8.5 ind 5 m -2 corresponding biomass 0.19 mg . overall sex-ratio statistically favour females (F:M=2.1). Brooding were collected regularly during whole year their fecundity estimated at 19.3 per marsupium. demographic analysis samples suggested that a trivoltine species. potential longevity individuals less than differs between generations. Using sizefrequency method, production 1.44 ash free dry weight -1 with ratio 7.79.
