The diagonal lines indicate the regions of Menemsha Bight where the flounder are captured in greatest abundance. By comparing this chart with Chart 4, it is seen that these regions coincide in general with those areas where Ampelisca macrocephala and Clymenella torquata occur in large numbers. SUMMARY 1. A dredge which is larger and heavier than those employed previously in quantitative marine bottom sampling has been used with a specially designed screen- ing device to facilitate the removal of organisms from the relatively large samples of bottom material. 2. The bottom of Menemsha Bight, a flounder fishing grounds'in Vineyard Sound, is divisable into five zones on a basis of the bottom material. Four of the zones possessed a distinct faunal aggregation. 3. The zone which extended from the 5- to the 20-meter depth contour and contained a fine sand bottom occupied 80 per cent of the area of the Bight. This zone contained the greatest quantity of the animals (per unit volume of bottom material) that are generally known to serve as food for fishes. Clymenella torquata and Ampelisca macrocephala were the most common organisms. Flounders are caught in greatest numbers in the regions where these animals are most , 4. The numerical distributions of Clymenella torquata and Crepidula jornicata are correlated with distinct characteristics of the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Marine Biological Laboratory (Woods Hole, Mass. ); Marine Biologic
