A Gillnetter is a type of fishing vessel specifically designed to use gillnets for catching fish. Gillnets are large nets that hang vertically in the water, allowing fish to swim into them and become entangled by their gills. This method is commonly used for various species, including salmon, herring, and cod. Gillnetters can vary in size and design, ranging from small boats to larger commercial vessels. They are often equipped with features like winches and storage areas for the caught fish. The use of gillnets is regulated in many regions to ensure sustainable fishing practices and protect fish populations.
