By the way, the fixed net having only the dropped portion cannot capture surface fish such as dolphins and skipjack. Also, the low-rise fish that entered the drop area could not go out due to barges, etc., and if left untreated for several days, they would often run backward and escape. Further, there is a problem that the surrounding net 1 and the box net 2 ′ whose upper edge 1a is located near the sea surface are liable to be damaged by the influence of waves due to a typhoon or the like.

According to the first aspect of the present invention, among fish that have entered the surrounding net, a surface fish such as a skipjack is captured in the box net from the first local net via the first funnel net. On the other hand, low-rise fish such as flatfish are captured from the second local net through the second funnel net and into the drop. In addition, since the box net is positioned outside the enclosing net and the box net is connected to the enclosing net by the local net, the enclosing net and the box net can be held by different side ropes. . Therefore,
Although a net near the sea surface is particularly damaged during a typhoon or the like, the box net can be easily separated from the surrounding net to be collected and evacuated. According to the invention as set forth in claim 2, when the eaves portion is provided, the surface fish having a high swimming power captured by the box net is prevented from going back into the first funnel net, and similarly, the drop portion is provided with the eaves portion. The captured low-rise fish is also prevented from going back into the second funnel net, thereby ensuring reliable catch.
If the upper edge of the surrounding net is lowered to a predetermined position below the sea surface as in the invention according to claim 3, it is less likely to be affected by waves near the sea surface, so that damage due to waves during a typhoon or the like is avoided. It can come off.

[0017] The fixed net constructed as described above can not only catch low-rise fish in a dropping portion near the sea bottom, but also catch surface fish with a box net floating near the sea surface. Further, each of the first funnel net 41 and the second funnel net 43 has
Since the eaves 61 and 62 that are opened only at the lower side are provided, the fish once passing through the eaves 61 and 62 and entering the box net 2 and the dropping part 5 cannot reverse and escape. In other words, surface fish such as bonito enter the box net 2 from the loquat net 31 via the jogo net 41, but even if the fish caught in the box net 2 goes back into the jogo net 41 and tries to escape, It is shielded and blocked by the eaves 61. A similar effect can be obtained by the eaves 62 provided at the tip of the funnel net 43 in the dropping portion 5.
2 prevents retrograde. Therefore, even if fishing cannot be carried out for many days due to barge or the like, a desired catch can be secured.

In addition, in the event of a typhoon or the like, the box net 2 is detached so as to avoid damage. On the other hand, the fixed net body can be prevented from being damaged by submerging it in the sea. Since the box net 2 is small and easy to separate from the net body,
It is easily removed from the surrounding net 1 together with the local net 31 and collected. With respect to the surrounding net 1 of the net main body, if the cedar rope 18 locked on the side tension rope 81 is released, the upper edge 1a of the surrounding net 1 stands and sinks along the squid 7 into the sea. Damage to the fixed net caused by shaking can be avoided. And
Since the ring 19 attached to the cedar rope 18 hits the stopper bar 71 and stops, it does not take much time to return to the original state after the typhoon or the like has left.

2, the shapes and sizes of the funnel nets 41 and 43, the dropping portion 5, the eaves portion 61, the standing squirrel 7, the stopper bar 71, and the like can be appropriately selected according to the use and the like. For example, it is not necessary to provide a ring from the upper end to the lower end of the cedar rope of the surrounding net. Further, the slidable connection between the side surface of the surrounding net and the standing squid may be made by a member other than a ring (for example, a cylinder).

As described above, the fixed net of the present invention has a structure in which the captured fish is difficult to escape, and can efficiently capture both low-rise fish and surface fish. In addition to being able to remove the easy-to-attach box net from the surrounding net, the main net can be easily submerged in the sea to avoid wave shaking, increasing the net catch of the fixed net and maintaining it for a long time. It has a tremendous effect, for example.
