Life history, growth and production of Neomysis integer in the Westerschelde estuary (SW Netherlands)

The Neomysis integer (Leach, 1814) (Crustacea, Mysidacea) population of the brackish part of the Westerschelde estuary was sampled on a fortnightly basis from November 1990 to December 1991. Density, biomass, population structure and brood size were recorded. The Bhattacharya method was applied to the length-frequency data for the detection and separation of cohorts. Growth is described both by a generalised von Bertalanffy function incorporating seasonal oscillations in growth. Secondary production was estimated for each cohort using 4 approaches. The seasonal pattern in density and biomass s... Mehr ...
