Naguara Net Salmon Gillnet Toray Nylon Color Samples from LFS Marine Supplies. These gillnets or gill nets are used for salmon fishing in Washington and Alaska, including Bristol Bay, Prince William Sound, Copper River, Hood Canal, etc.
A gillnet is a wall of netting that hangs in the water column, typically made of monofilament or multifilament nylon.
Mesh sizes are designed to allow fish to get only their head through the netting but not their body. The fish's gills then get caught in the mesh as the fish tries to back out of the net. As the fish struggles to free itself, it becomes more and more entangled. A variety of regulations and factors determine the mesh size, length, and height of commercial gillnets, including area fished and target species.
There are two main types of gillnets:
Set gillnets are attached to poles fixed in the substrate or an anchor system to prevent movement of the net.
Drift gillnets are kept afloat at the proper depth using a system of weights.
