Abstract
    The efficiencies of a 2-m and a 1.5-m beam trawl for catching newly settled flatfish and brown shrimp were compared with that of a 1-m2 drop trap that was assumed to be 100% effective. Low and variable trawl efficiencies were recorded but the trawls were not size selective within the size range of individuals captured.
