Thirty drags over a 21-day period caught only 689 pounds of spot shrimp, nearly all taken "on bottom" (table 1-^). Catches of spot shrimp were greater in the early evening and at night than during daylight. The largest catches of spot shrimp (225 pounds per 105-minute drag and 160 pounds per 85-minute drag) were taken on bottom near the head of Carroll Inlet. POT FISHING The last 6 days of the cruise were devoted to pot fishing to compare the effectiveness of a commercial shrimp pot operation with the trawling effort. Methods and Gear Shrimp pots were fished in Willard Inlet and Mink Bay, a tributary of Boca de Quadra Inlet (fig. 2). Several d if fe r en t sizes and shapes of pots were used; however, the basic design was a two-tunnel pot with 2 by 3 by 3- foot rectangular metal frame covered with I4- inch stretch mesh nylon webbing (fig. 3). Most posts were fished singly--one to a buoy line. However, one "longline" with 10 pots was also used. AH pots were baited with fresh hair seal meat hung in the center of the trap. Pots were usually fished overnight but, occasionally, were fished longer periods. Results of Pot Fishing During 5 days of fishing, 985 pounds of marketable shrimp were taken. Willard Inlet. Fig. 3 - Commercial shrimp pot used during the last phase of Nancy Rose cruise. produced 929 pounds for an average catch of pounds of shrimp per pot (table 2^). An overnight set of 47 pots took only 56 pounds of shrimp in Mink Bay. Spot shrimp, which av- eraged 22 tails per pound, were more than 90 percent of the pot catches. Small quantities of coonstripe and pink shrimp were also taken. CONCLUSIONS Results of the Nancy Rose cruise show
