Description

[Detailed description of the invention] (Field of industrial application) This invention is a set net used for coastal fishing, and is used to guide fish between the encircling net of the set net and the bag net (also called a pool). This relates to the water net used.

(Prior Art) As this type of fishing net, one having a configuration disclosed in Japanese Utility Model Publication No. 54794/1983 filed by the same applicant is known. In this known Jogo net,
It is generally called a square mesh mesh surrounded on all four sides and has a funnel-like shape as a whole, with the net located at the bottom being a bed net, the nets located on both sides being side nets, and the top. The net is called a ceiling net.

A fishing net with such a configuration has a bottom net,
Since the nets on both sides and the ceiling are of approximately the same length, the entire net is tunnel-like, and the inside of the net is generally dark. Therefore, not only are schools of fish unable to be guided quickly by avoiding the darkness, but the opening side of the fishing net is narrow, which increases the density of the net material, making it susceptible to tidal currents. It also has points.

(Problems to be Solved by the Invention) The present invention attempts to solve the problems in the conventional example, namely, the problem of guiding schools of fish due to the darkness inside the fishing net, and the problem of being easily affected by the current on the opening side. It is something to do.

(Means for Solving the Problems) As a specific means for solving the above-mentioned problems, the present invention provides a wall net formed of a floor net, both side nets, and a ceiling net, in which a part of the ceiling net is formed into an opening. This invention provides a stationary net for fixed netting, which is characterized by having a ceiling opening formed by removing it from the side, and since a part of the ceiling net is removed, the inside of the net is bright. Schools of fish can be guided quickly, and since a portion of the ceiling net is removed, the density of the net material becomes coarser, reducing the influence of tidal currents.

(Embodiment) Next, the present invention will be described in more detail with reference to the illustrated embodiment. Reference numeral 1 denotes a surrounding net, and a catch net 2, that is, a bag net 2, is attached to a part of the surrounding net. The enclosure net is usually called a playing field, and is more than ten times as wide as a bag net. A cage net 3 is disposed between the enclosure net 1 and the bag net 2, and the pot net has an approximately truncated pyramid shape as a whole, and is provided in a state protruding toward the bag net 2 side, and its opening 4 is open in the bag net 2.

This funnel net 3 is formed in the shape of a truncated pyramidal funnel by a lower bedding net 5, side nets 6 and 7 on both sides, and an upper top net 8, and the opening 4 of the funnel net 3 is normal. In order to maintain the open state, a plurality of tension ropes 9, 10, 11, and 12 are used to maintain tension. In such a ceiling net, a portion of the ceiling net 8 is removed to form a ceiling opening 13.
This ceiling opening 13 is provided at the narrow opening 4 side of the cage net, and by providing this ceiling opening, the interior of the cage net becomes relatively bright. In other words, when a school of fish that has entered the enclosure net 1 encounters the position of the fishing net 3 while migrating along the enclosure net, and the back of the fishing net is narrow and dark, it will avoid the fishing net and migrate. , and cannot be guided into the bag net 2 quickly. Therefore, if the back of the fishing net 3 is bright, a school of fish that encounters the fishing net 3 will be guided along the net towards the bright side by their habit and will quickly enter the bag net 2. In other words, the brighter the depths of the net, the easier it is to guide the school of fish. Also, regarding the fishing net,
Because the opening 4 side is narrowed,
As the density of the net material increases, it becomes a large resistance area when exposed to tidal currents, but by providing the ceiling openings 13, the density of the net material becomes coarser by that amount, and the resistance to tidal currents becomes smaller, making it easier to use water nets. This prevents the opening 4 from deforming or shifting to one side. Incidentally, reference numerals 14, 15, 16, and 17 in the figure are ropes for holding the surrounding net 1 and the bag net 2 under tension.

(Effects of the invention) As explained above, in the cage net according to the present invention, by providing a ceiling opening in a part of the ceiling net constituting the cage net, the inside of the cage net becomes relatively bright, and the inside of the cage net is illuminated. It has the excellent effect of being able to quickly guide migrating schools of fish into the bag net. In addition, since the ceiling opening is provided near the opening of the river net, when the density of the net material on the narrow opening side becomes coarse and receives the tidal current,
The resistance is reduced, which has the excellent effect of allowing the opening of the river net to always maintain its normal state without being biased or distorted by the current.
