CHAPTER 5 Pots The words “pot” and “trap” are used interchangeably to mean baited cages set on the ocean floor to catch fish and shellfish. They can be circular, rectangular or conical in shape. The pots may be set out individually or as strings with multiple pots attached to a groundline (See Figure 5- 10). All pots contain entry ports and escape ports that allow undersized or unwanted species to escape. Additionally, all pots must have biodegradable escape panels or fasteners that prevent the pot from continuing to fish if lost. Strings of pots are marked at each end with a pole and flag, and sometimes a light or radar reflector. Individual pots are marked with surface bouys. Figure 5 - 10: Trap Vessel 5-12 1/30/2004
CHAPTER 5 Sablefish Pots Sablefish pots are fished in strings weighted with anchors at each end and marked at the surface with buoys and flagpoles. The pots are rectangular, trapezoidal, basket, or cylindrical in shape and usually weigh less than 50 pounds (See Figure 5-11). Rectangular and basket-shaped pots have collapsible bottoms so more pots can be stacked on deck. Pots are set and retrieved using line haulers and hydraulic blocks and overhead hoists. Pots are baited with squid, hake, or herring. Figure 5 - 11: Sablefish Trap Schematic 1/30/2004 5-13
