Description

DRIFT GILL NET}

The present design relates to a drift net, and more specifically, even if a specific part of the net is damaged, the damaged area does not expand as a whole, and an arc-shaped residence space is naturally provided in the net. It relates to a drift net capable of minimizing the departure of fish during salvage.

In general, nets for catching fish are produced and used in various forms, but nets are laid vertically on the surface of the water in the form of a fixed net or towel that is laid in a certain place for a certain period of time to catch fish, and the fishes are inserted into the net. Fishing nets are mainly used.

For example, as shown in Fig. 1A, a driftnet is mainly used in which several weights 4 are fixed at the lower part of the fishing net 1, and the support rope 2 and the father 3 are fixed at the upper part, but when the fishing net is lifted There is a disadvantage that it is easily damaged due to pressure contact with the roller 6.

As a way to compensate for these shortcomings, a promising network as disclosed in Korean Utility Model Publication Registration No. 20-0392990 has been proposed.

As shown in Fig. 1b, the drift net according to the Utility Model Registration No. 20-0392990 connects the protective fishing net 1A to the upper part of the fishing net 1, while the support rope 2 is tied with several rich children 3 ( It is formed in a loosely fixed form with 5).

The driftnet according to the above-described utility model registration No. 20-0392990 is loosely fixed to the support rope (2) by a string (5), so that the driftnet is damaged by pressure contact with the lifting roller when lifting. Although it can be prevented, there is a limitation that accompanies various problems as follows.

The above-described conventional driftnets have a disadvantage that the entire fishing net has to be discarded as it is difficult to repair and takes a lot of time as the entire damaged area is enlarged as adjacent nets are broken in succession when the net in a specific area is broken during lifting or in a laid state. .

And, in the conventional driftnet, when the top of the fishing net including the rich man 3 is moved in the current direction by the tide in the state of being laid in the water, the overall shape of the fishing net 1 is changed in a diagonal direction based on the lower weight 4 Since it is tilted, there is a disadvantage that fish cannot be easily captured.

In particular, the conventional driftnet has a disadvantage in that it is impossible to perform stable fishing activities because the fishing net 1 has a flat structure even when lifting, so that fish pierced in the mesh are easily separated.
