CHAPTER 5 I. Fixed Gear Description Hook and Line Gear Numerous varieties of commercial fishing gear use hooks and lines in different configurations to catch finfish. The most common gear configurations include longline, vertical hook and line, jigs, handlines, rods and reels, vertical and horizontal setlines, troll lines, and stick (pipe) gear. Groundline/Mainline- The length of line to which all of the hooks are attached. This line is the “backbone” of the longline gear. Gangion- The length of line that connects the hook to the groundline. It is often one to two feet long. Block- A hydraulically driven wheel into which the groundline is placed during gear retrieval. As the wheel spins the groundline is drawn aboard. Rollerman – A crewman who stands where the fish are coming in and brings them aboard using a gaff.. The rollerman lands any commercially valuable fish and excludes any non-commercially valuable fish from being landed. Crucifier- A pair of rollers or steel pegs which stand vertically with only enough room for the groundline to pass between. During gear retrieval, the groundline passes between the rollers and the hooks are pulled out of the fish. Longline Gear This gear type involves the setting out of a long horizontal line (groundline/mainline) to which other short lines (gangions) with baited hooks are attached. The groundline is secured between anchored lines and identified by floating surface bouys, bamboo poles, and flags. The groundline is laid along or just above the ocean floor (bottom longline) (See Figure 5-1). To deploy longline gear, the vessel sets the first anchor and then steams ahead, following a selected pathway with the groundline and baited hooks being set off the stern of the boat. Hooks are usually baited by hand with squid, herring, octopus, or cod. Hooks of various sizes are attached to gangions of various lengths that are tied on or snapped onto the line at desired intervals. Hook size and spacing, depth, and soak time (fishing time) vary. Longline gear is retrieved by pulling in the groundline and landing one gangion and hook at a time. On most longliners (See Figure 5-2), the vessel pulls the buoy aboard then pulls up the anchor using a block. The rollerman transfers the groundline to the block and begins hauling the groundline. The line comes in over the rollers, through the crucifier, over the block, and then is coiled. A rollerman stands at the railing of the vessel and helps the fish aboard. Some longliners on the <strong>West</strong> <strong>Coast</strong> manually pull the buoy 5-2 1/30/2004
