A gillnet is a wall of netting that hangs in the water column, typically made of monofilament or multifilament nylon. Gillnet. 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.
Summary. . . Tangle nets are a particular design of a gill net where the netting is hung onto the ropes to create a greater amount of slack netting. This gear will usually have less flotation on the head rope and will not stand as high when fishing, as the average gill net. Trammel net shot over a wreck.
Gillnetting is a fishing method that uses gillnets: vertical panels of netting that hang from a line with regularly spaced floaters that hold the line on the surface of the water. The floats are sometimes called "corks" and the line with corks is generally referred to as a "cork line." The line along the bottom of the panels is generally weighted.
A gill net is a single wall of netting anchored on the seabed to catch fish that swim into it. Gill net is also collective name for many different styles of nets as well as being a style of net in itself. Many of these nets will be referred to differently in different fisheries.

Profile. General Description: Gillnets and entangling nets are strings of single, double or triple netting walls, vertical, near by the surface, in midwater on on the bottom, in which fish will gill, entangle or enmesh. Gillnets and entangling nets have floats on the upper line (headrope) and, in general, weights on the ground-line (footrope).
A gillnet is a wall or curtain of netting that hangs in the water. The term covers several forms including stationary gillnets and trammel nets. Gillnets generally have low environmental impacts with minimal seabed interaction. The size of fish caught can be determined by the mesh size, helping to avoid catching juvenile fish.

The numbers of discard fish that die following release from gill nets is likely to be very high in some fisheries. A study in the Columbia River found that survival rates of spring chinook salmon released as bycatch were nearly twice as great for those captured in a 4.5-inch mesh tangle net than those caught in a conventional 8-inch mesh gill net.
