retrieving a gillnet from the water, the mesh is 1&1/2". The catch is primarily
white perch. The gillnets are experimental multi-mesh gillnets. All nets are
connected to a string of nets containing different size mesh between 1&1/2",
2&1/2", and 3&1/2" mesh. Gillnets are made with a lead line that sinks to the
bottom and a float line that keeps the net just below the surface of the water.
