Gillnetting

Gill nets are usually made of a single piece of net from einfädiger or braided nylon cord existing fishing nets.

As with the driftnet fish is caught when he tried to swim across the network, and will remain stuck with his head. In subsequent liberation attempts, he gets tangled up then the net.

The use of the control network is common in both inland and in coastal fishing. The networks are differentiated according to the type of their erection. Pelagialnetze be placed on floats suspended at the desired depth in open water. In the lower ground networks sinking line is heavy enough to compensate for the buoyancy of the upper swimming Chur. The network therefore sinks to the seabed. Unlike driftnets are possible if firmly anchored at both ends of gill nets. In the inland fisheries lengths of around 30 m are common.

One advantage of the gillnet fishery is the relatively easy maintenance of the equipment and the possibility of targeted catch by mesh size and placement of the network fish of a certain size and type. Since the sensitive mucous layer of fish while fishing gets hurt and the fish beyond verhedderen often so strong that they can not be freed unharmed, caught fish are the gillnet not suitable for Lebendhälterung and must be killed immediately.

Target fish in inland fishing mostly whitefish ( Whitefish ), perch, pike, tench, carp, pike and coarse fish. In the coastal fisheries, especially herring, but also cod, sea trout, flounder and plaice.

The use of gillnets in the inshore fishing is supposed to be great because of the bycatch of marine mammals such as porpoises and ducks as eider and long-tailed duck, but also loons as red-throated divers, controversial. The Federal Agency for Nature Conservation leads through an investigation.
