Abstract

PURPOSE:To improve the fishing efficiency of fixed shore net, by forming a inclined funnel part to a leader net and connecting the funnel part to a body net. CONSTITUTION:A funnel part 5 is attached in order to smoothly guide fishes from a leader net into a body net 6. The funnel part 5 is connected to the body nets 6, 7 via a corridor 8. The fish cannot escape from the body nets 6, 7 once entered. The collapse of the shapes of the body net 6 and the leader net 5 is prevented by attaching a reinforcing ring 11 to the body net 6. Since the deformation of the net is prevented, the entering rate of fish can be improved.

Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention relates to the improvement of fixed nets, which improves the ability of fish to enter the net, and allows the fish to be farmed for a certain period of time without letting them escape. This invention relates to a fixed net that can be used to haul nets according to the type of fish caught in the net and the condition of the fish.

(Prior art) In fixed nets, fish that have entered the net along a fence net are guided through the ascending net section to a box net or drop net (hereinafter collectively referred to as "box net"), and then the box net is lifted up. It has a structure that collects and captures fish on a stand/fish catch section attached to the far end. Conventional fixed nets are designed to improve the entry of fish into the net in order to efficiently catch fish within a limited range. It becomes. And traditionally,
It was common practice to raise box nets at regular intervals and pick up all the fish that had entered the net.

(Problem to be solved by the invention) However, in recent years, the frequency of handling of landed fish has decreased due to an increase in market holidays and restrictions on sales hours, and changes in color value due to changes in the distribution system, etc. There are significant disadvantages to the traditional fixed net fishing method.

With these changes in the situation, fishing grounds are also dealing with it by reducing the number of times the net is hauled in to catch fish, but the traditional fixed structure '+M' that improves the net entry has been reversed. This is a structure that makes it easy for fish to come out, and if the number of times a fixed net with this structure is hauled is reduced, the amount of fish caught will also decrease proportionally.

In addition, in the conventional structure where all the fish that have been seduced are salvaged, if you try to take up fish whose prices are increasing, you will also have to catch fish whose prices are decreasing at the same time, making it impossible to deal with fluctuations in color value in detail. It is also undesirable for the sake of protecting non-resources.

The purpose of this invention is to solve the above-mentioned problems, and to prevent the overall catch from decreasing too much even if the number of nets hauled is reduced, and to adjust the number of fish to be caught in accordance with market conditions. The purpose is to obtain a fixed net that allows you to select as many types as possible.

(Means for Solving the Problems) The fixed net of the present invention has a net fabric 5a of the fishing part at the rear end of the box net 2.
A tilted funnel part is formed in the lifting part 5 more than before, and a safe net 6.7 is connected to the back end of the funnel part 5 via a corridor 8. The safe m6.7 is
A plurality of safe nets are connected through a through net 10, and loop holes 11 are attached to the four corners of the safe net to fix the net.

(Function) If the lifting part of a conventional fixed net is shaped like a box, fish will stay in that part and will be difficult to enter the safe net, but in the fixed net of this invention, the lifting part of the box net 2 Part 5 is funnel-shaped, so it's a box! The fish that have entered ii2 enter the safe net 6 from the funnel part 5 through the corridor 8 in a natural swimming state, reducing the number of missed fish and improving the yield of large-scale fish. Therefore, it is possible to increase the catch by reducing the number of missed fish during periods when the market is not open and nets are not hauled. The lifting part has a fine mesh so that even small fish can be guided to the safe Y46 without missing.

Furthermore, if the safe nets are connected in two and three tiers, the fish entering the net will be successively driven into the safe net 6.7 at the back.

When catching fish, you can use the thread Y410 according to the fish species to drive the fish from one safe net to the next, allowing you to separate the fish species and only lift the safe net containing the desired fish. By using nets, it is possible to catch only the necessary types of fish and further stock other types of fish, making it possible to simultaneously select fish and adjust shipping.

In addition, when catching large fish or landing a large quantity of fish, the fishing boat is stopped at the attachment point of the funnel-shaped lifting section, and the lifting section of the box net is pulled up in the same way as before. Let's catch a fish.

The openings provided at the four corners of the safe net serve to prevent the shape of the safe net and box net from deforming. With fixed nets, if the net is deformed by tidal currents, the quality of the fish may deteriorate.
It is better to make the rope shape so that it does not deform as much as possible in order to improve the catch, since the fish entering the net may be affected by A)M. Previously, some fixed nets were used to climb the ropes, and then they were transported to the playground and installed with holes to prevent the ropes from losing their shape. However, it was considered operationally impossible to attach transport holes to the box nets that were hauled out on a daily basis. In this invention, the safe net 6
Attach the screw 11 to the box to prevent the shape of the safe net from shifting and at the same time prevent the shape of the lifting part 5 of the box net from collapsing.
The iA2 has a structure in which a loop hole 4 is attached to the corner 3 of the Otafuku to maintain the shape of the entire box net and increase fishing efficiency.

(Example) Fig. 1 is a perspective view of the main parts of the fixed net of the present invention, Fig. 2 is a plan view, and Fig. 3 is a side view, where 1 is an ascending net portion, 2 is a box net, and 3 is a box net. The corner of the Otafuku, 4 goes through the ring provided in the corner of the Otafuku, 5 is the lifting part of the box net, 6 and 7 are the safe nets,
8 and 9 are corridors, 10 is a passageway provided between the safe nets 6 and 7, and 11 is a ring provided at the four corners of the safe net 6 and 7.

box'! As shown in FIG. 5, A2 has a mesh fabric 5a forming the raised portion 5 longer than the conventional mesh material shown in FIG. Sew with .21. In FIGS. 5 and 6, the portions where the line spacing showing the mesh is narrowed indicate the portions where the mesh size is made finer. Since the corner 3 of the net of the box net is formed vertically, a hollow 4 is provided in this part to prevent the shape of the base end (on the rising net side) of the box M42 from interfering with the net lifting operation of the box body. We are trying to prevent this.

A lobe 23 (see Fig. 4) is attached to the tip 22 of the funnel-shaped lifting part 5 for lifting the part, and when this part is pulled up and the passage leading to the safe net 6 is blocked, It has a structure that allows the netting to be carried out in the same way as a regular box net.

The safe Y46.7 has the same structure as the conventional one, but the safe M
46 is connected to the tip of the lifting part 5 of the box net formed in the shape of a funnel, and the structure is such that it encourages the fishing of fish to the safe net 6. In the illustrated embodiment, the safe nets are provided in two stages, the safe nets 6, 7 are connected to each other by a corridor 9, and a through net 10 is provided between them. The safe net 6.7 is provided with loop holes 11 at its four corners, so that the safe net 6.7 can be moved by tidal currents, etc.
7 from being deformed, and preventing the safe net 6 from deforming also serves to prevent the lifting part 5 of the box net 2 from deforming, Together with 4, this prevents the entire box net 2 from deforming.

(Effects of the Invention) According to the fixed net of the present invention, there are fewer escape nets for fish that have already entered the net, increasing the exit rate of fish entering the net, and allowing fish that have entered the net to be naturally guided to the safe net. Because the fish are farmed in a safe net, the catch does not decrease even if the number of fishing trips is reduced to match the market schedule, making it possible to obtain a more reliable catch than with conventional fixed nets. In addition to being able to carry out hauling nets in the fishing section, by providing multiple safe nets, various netting operations can be performed according to the type of fish to be caught, allowing you to select the type of fish to catch. Because of this, fishing efficiency is improved and fish resources are not wasted.

Furthermore, the structure is designed to reduce changes in the shape of the box net and safe net due to tidal currents, etc., so it is possible to increase the number of fish entering the net and reduce the number of fish that escape. You can keep it.
