. Commercial fisheries review. Fisheries; Fish trade. 58 was emphasized. The catch rates would have beenhigher had we sampled intensively those areas where large catches were made. Also, the gear used was a rather small sampling unit designed for a rapid survey. GEAR The bottom longline or "trawlline" con- sisted of three 100-hook baskets of gear shackled together. One basket each of sizes 6, 7, and 9 circle hooks baited with squid or ladyfish was fished at each station. Hooks on. 6- to 12-inchmonofilamentgangions were at- tached at 10-foot intervals to a 4-inch poly- dactylene or nylon mainline. The line was coiled in shallow wooden notched boxes and set off the stern (fig. 2). Fishing time varied from 1 to 2 hours. The gear was re- trieved with a Japanese longline hauler de- signed for tuna andswordfish longlines. The short gangions and circle hooks went through the roller and hauler easily, so the fishermen had to handle the line only when removing fish (fig. 3). Including running time between sta- tions, as many as 8 gear sets were made within a 24-hour period. The only sizable losses of gear occurred when sets were m ad e on s napp e r lumps. There, hangups were frequent. Jarvis, in 1935, and Whiteleather and Brown, in 1945, reported large gear losses from bottom long- line sets made on rough bottom in the GuK and Caribbean. Most of the Oregon II sets, however, were made off coral areas and little fouling took place. Overall, only about 2 per- cent of the total hooks fished were lost. AREA FISHED Exploratory fishing was conducted off Texas and Louisiana, the northern edge of the Campeche Bank, the west coast of Florida and m the northern Gulf from Cape San Bias, Fla., to the mouth of the Mississippi River (fig. 4). Fishing was done off the Texas and west.
