RESULTS Thirty-three species of bivalve mollusks were collected on the southeastern Bering Sea shelf (Table 66-3). Nucula tenuis was broadly distributed (Fig. 66-8) over the southeastern Bering Sea shelf with greatest abundance at Stations 1, 11, 12, 18, 19, 28, 29, 30, 63, 71, 72, 82, 83, 935, 937, 939, and 942 (Figs. 66-8, 66-9, and 66-10; Table 66-4). It was present at 77 percent of the stations sampled by van Veen grab, in greatest biomass at Stations 19, 28, 29, 63, 71, 83, and 935 (Table 66-4). It was associated with sedi- ment types ranging from fine sand to medium silt (; Tables 66-1 and 66-2, Figs. 66-3 to 66-6; Table 66-5). Major Component of Collection: Ninety-one percent of N. tenuis collected occurred in fine sand to medium silt (); 75 percent of the
