Miget and G, Finne Texas Agriculture Extension Service Texas ASM University College Station, Texas 77843 INTRODUCTION An initial longlining trip for sharks was completed out of Brownsville aboard Captain Carl Gayman'svessel, S.S. Missionary Ridge, from May 20-28, 1981. Specialized shark gear which could be incorporated with swordfish longlining vessels was constructed and evaluated. Fish production relative to water depths, baits, species, and hook numbers was quantified. This re- port discusses some of the results from this initial effort. PROCEDURE Gear During the first two weeks in May, shark longlining gangions were con- structed. Although the cooperating vessel was already rigged for longlining, specialized gangions had to be suppled for shark fishing. Snaps used on the gangions consisted of a heavy duty A/K Longline Snap constructed of .144" wire. An 8/0 swivel was attached to the longline snap. Thirty feet of 5001ktest mono- filament leader was connected to the snap. Three feet of lx7-1/16" stainless steel leader separated the monofilament line from the hook. An 8/0 swivel was used to attach the monofilament line to the stainless steel leader. Mustad 34/0 Shark Hooks-No. 34970were used on all gangions. Past experiences with stainless leader attached to ringed tin hooks had indicated excessive amounts of electrolysis in the eye of the hook. Some fishermen reported that only 2-3 trips could be performed before the eye of the hook completely corroded away. To control this problem, resulting from dissimiliar metals, strips of alumimum were cut and wrapped around both the hooks and the wire bites adjacent to the swivels. These anodes worked satis- factorily on this first trip; however, electrolysis of the anodes was so rapid that it appears that two trips will be the life expectancy of the material. Lon line Gear Arra Hooks were spaced approximately 150-200' apart. Six to seven hooks were placed between 40" inflatable bouys. HifIyers with radar reflectors and lights were placed at intervals of every 50 hooks - approximately lg n. miles. Buoy drops were 30 feet in length. Mainline consisted of f7 braided line. Initial sets were put over at midnight and allowed to drift until 10 or ll a.m. Although it is known that sharks are not caught in abundance at night, it was anticipated that some swordfish could be caught through a portion of the trip to subsidize the operation. No yields of swordfish were obtained; more- over, currents were such that the drift of the line was too erratic and often was not in the desired areas in the daylight hours. As a result, sets made in t'he latter portions of the trip were put over just before daylight so that positioning of the gear could be more closely achieved. Baits Several different types of bait were used and evaluated during the trip. It was learned that bait can dictate fishing success. The primary bait uti- lized was Atlantic mackerels This was, by far, the most successful.
