Each pot has a polypropylene or similar line with a plastic foam buoy attached (fig. 5). The line is 10 to 20 fathoms long, de- pending on the depth to be fished. The buoy is 18 inches long by 4 inches in diameter and tapered at the bottom end to reduce chances of fouling by kelp. The buoys and lines must both be dipped periodically in a chlorine solution to remove fouling organisms, primarily algae and hydrozoans. METHOD OF FISHING Just before the fishing gear is set, the skipper selects a course and sets the ves- sel's autopilot. It is important that the boat be maintained on a straight course to facili- tate the recovery of pots in rough or foggy weather. As the setting of gear begins, the buoy line and buoy of the first pot and a colored float used to mark the end of the string of pots are trailed behind the boat. At word from the skipper, the first pot is pushed overboard. The next pot and its line and buoy are carried to the rail. The proc- ess is repeated until the last pot of the string, also marked with a colored float, is set. A string may contain 30 to 60 pots. Each boat fishes several strings. These usually are set parallel to each other, and approximately parallel to the beach in 5 to 20 fathoms. An efficient crew can lift and reset over 300 pots in a 10-hour day. In good weather, 2 deck hands can pick and reset more than 60 pots inanhour. To attain this rate, an as- sembly-line approach must be used in han- dling the gear. The boat is brought along-.
