Boat Net Nimble
Gillnets are used to capture Alaska's salmon in both personal and commercial fisheries. Gillnets can be fished off a boat or set along the shoreline. A gillnetter is a boat engaged in drift gillnetting, while fishing a gillnet with one end anchored to the shore is called setnetting.
Description of Drift Gillnets and Fishing Technique
Gillnets are constructed of multifilament synthetic fibers woven into a mesh. Fish are captured when their gill cover plates snag on the fibers. Mesh size determines the size of the fish caught. Larger fish aren’t captured in smaller mesh sizes and fish too small for the selected mesh size will pass through it. Selection of mesh size can determine the species and sex of a salmon being targeted by a fishery.
A gillnet is a curtain of net that hangs vertically in the water. The top edge of the net is supported by floats and is called the floatline. A weighted line called the leadline holds down the lower edge of the net. Nets can be configured to meet fisheries management goals by changing their depth, length, and mesh size. Net depths can vary from 32 to 42 feet and nets can be 900 to 1,800 feet long. Lengths are often expressed in fathoms, which are equal in length to six feet or about two meters.
