Production and Abundance of Juvenile Nereis Diversicolor, and Oogenic Cycle of Adults in Shallow Waters of Western Sweden

Certain shallow-water embayments (< 1 m) along the Swedish west coast have recently been documented as highly productive areas for both infauna (Moller & Rosenberg, 1982, 1983) and mobile epifauna (Pihl & Rosenberg, 1982) as well as important nursery and feeding grounds for fish (Pihl, 1982; Evans, 1983). The present report, dealing with Nereis diversicolor O. F. Miiller, complements the earlier descriptions of recruitment, abundance and production of the dominant infauna species Mya arenaria L., Cardium (Cerastoderma) edule L. and Corophium volutator (Pallas) in these rather sheltered shallow areas in the archipelago of western Sweden.
