The importance of shallow soft bottom areas as nursery grounds for I-group cods, Gadus murhua, and I- to IV- group flounder, Platichtys flesus, was investigated in a 20000 m² bay, 0 to 1 m deep, on the Swedish west coast. To estimate the amount of visiting fish and their food intake the bay was enclosed with a net once a month from July to November 1979 and from April to November 1980. At each occasion about 60 cods and 8 to 50 flounders wre caught. The total biomass of the cod and flounder was 1 to 14 kg and 2 to 13 kg wet weight respectively. The cod preyed on mobile epifauna such as Carcinus maenas, Crangon crangon and Pomatoschistus spp., whereas the flounder was eating infauna mainly Mya arenaria, Cardium spp. and Nereis spp..The food intake within the area was calculated to, approximate 35 and 10 kg wet weight from April to November for cod and flounder, respectively.
