in sight at all times. As the vessel ordinarily drifted faster than the nets in 

 the wind, it was necessairy to run up on the lights three or four times in a night. 

 At dawn, the nets were hauled, the catch removed, and trolling resumed. 



In hauling, the vessel approached the nets from the lee side so that it 

 would tend to drift away and not fotil in the gear. Some difficulty was experi- 

 enced in maneuvering the Cobb alongside the nets, 

 especially in choppy seas, because of the tendency 

 of the large super-structure to catch the wind. 

 On one such occasion the net was parted in a 

 20 m.p.h. northwest wind, but no other serious trou- 

 ble occurred. Hauling was done from the starboard 

 side amidships. The nets were brought in over a 

 regular shark gill-net roller, 28 inches long and 

 6^ inches in diameter, and were hauled around a 

 rubberized sheave 20 inches in diameter powered 

 from a take-off on the main trawling winch. Most 

 of the albacore were removed from the nets on a 

 plywood table extending between the roller on the 

 rail (and under the rubber sheave) to the hatch 

 cover. When the tuna were too closely bunched in

Most of the albacore taken by gill nets 

 appeared to be in good condition. Nearly all were 

 dead when hauled aboard. Occasionally, especially 

 in choppy seas, fish were damaged in the web, either 

 from the strain exerted on the meshes as the vessel 

 drifted in the wind or from being hauled over the 

 roller. A larger roller than the one used on this 

 survey might result in less damage to the tuna. 

 Also, the addition of a heavy warp line to take 

 some of the strain of hauling off of the cork line 

 might lessen the web damage to the fish. Besides
