the seabed. The double or Spanish system is the same but it has a second, safety line. It is used in
areas where strong currents and rough floors otherwise cause high gear loss. The safety line is
unweighted and floats above the main line, attached at several points. This allows the main line to
be retrieved even if it breaks.

Three methods are employed. The most widely used method involves lines with buoys and
buoylines of variable lengths (Fig. 2). Weights are used to keep the line from drifting from its
midwater position The second method is the only "throwaway" gear, with a thin monofilament
mainline attached to many floats. All floats are hauled before the line is hauled, resulting in
irreparably tangled lines. Only the pollock fishery in Korea uses this
