DEEP-WATER SHRIMP TRAWLING TRIP COMPLETED BY "OREGON" (Cruise 34): The basic objectives of this trip were to obtain (1) additional exploratory cov- erage of the 100- to 300-fathom area in the eastern and north-central Gulf of Mexico between Cape San Bias and Tampa Bay and (2) preliminary trawling coverage of the red shrimp depth range along the Louisiana coast west of the Mississippi Delta. The Oregon completed the second part of this 3-week deep-water shrimp trawling trip on September 26. Sixteen drags using a 40-foot trawl were made in 125 to 275 fath- oms alons the Florida coast be- tween 87 west longitude and 28 north latitude. Catches of red shrimp throughout this area were small (1 to 14 pounds per 2-hour tow). No indications of commer- cial concentrations were located "" south of 29°30' N. and 87°08' W. (210 fathoms west of Cape San Bias). From this position west to 88^05' W. good catches were made in depths of 200 to 225 fathoms. Trawling with an 80-foot balloon net, 150 to 295 pounds of red shrimp were caught per 3-hour drag, averaging 225 pounds per drag. Fifteen drags with the 40-foot trawl were made along the Louisiana coast in depths of 100 to 300 fathoms west of Southwest Pass. Catches ranged from 6 to 13 pounds per drag in the 150- to 300-fathom range. Due to poor trawling bottom throughout this area, 2 nets and doors were lost and 3 other drags resulted in se- vere tearups. Two drags were made off Southwest Pass in depths of 55 to 65 fathoms to ob- tain silver porgies (Stenotomus caprinus) for future trials as tuna long-line bait. A total of 250 pounds of 8-10 to the pound porgies were frozen. Ten pounds of very large (3-5 heads-on to the pound) brown-grooved shrimp were also taken in each catch. Large numbers of schooling blackfin tuna and skipjack (Katsuwonus pelamis) were observed throughout the areas worked. Night-light col
