Description

[Detailed description of the invention] The present invention relates to a method of operating a purse seine.

1 to 3, a conventional general purse seine operation method will be explained. In FIG. Then, it runs through a plurality of rings 4 attached to the hem of the purse seine fishing gear 1 and is dropped, and one end of the ring 4 is fixed to the hull of the retsuko boat 6 together with the fish catching part of the purse seine fishing gear 1.

After dropping the steel fishing gear 1, the steel boat A and the retsuko boat 6 approach each other as shown in Fig. 2, and then, as shown in Fig. 3, the steel ring 5 and steel end steel 9 towed by the retsuko boat 6 are placed inside the net boat A. The ring net 5 is connected to the wire 5' of the purse winch 2' on the net boat through one of the purse blocks 3'', and the ring winding is started only by winding it up. .3 Figure 8 shows the major wire.

This method of operation is widely practiced both domestically and internationally, and it is common to use retsuko boats (or skiff boats), ranging in size from about 19G/T to over 1000G/T.

However, in the case of the above-mentioned conventional method, it is necessary to use a retsuko boat, which requires 1 to 2 people as crew members to cast the net, and because the retsuko boat is a small boat compared to the size of the net boat, it is necessary to use a retsuko boat. The current situation is that under the above sea conditions, it cannot be used and operations are often restricted. In addition, even with experienced crew, depending on sea conditions, it may be impossible to bring the retsuko boat close to the net boat, and the ring line 5 or net end line 9 may not be able to be retrieved, leading to accidents in which fishing gear is damaged or completely lost. There is.

It is widely known that in purse seine fishing, the quality of the process from casting the net to hoisting the net largely determines the success or failure of the operation, so there was a need to ensure that this process was carried out reliably.

The method of the present invention was developed in consideration of the current situation, and it eliminates the drawbacks of the conventional method by simple and rational means, and also saves manpower and labor in purse seine fishing, ensures reliable operation, and improves weather conditions. The aim is to increase the degree of freedom in which operations can be carried out regardless of factors that inhibit operations, such as sea conditions, and at the same time to improve operational safety.

Next, embodiments of the present invention will be described with reference to FIGS. 4 to 6.

Part of the operation is the same as the conventional method, but the fourth and fifth
As shown in the figure, a towing line 11 is installed through the perspective block 3'', and a shackle, a G-type hook, etc. Furthermore, a net end rope 9 and a buoyant body 12 are attached to the ends thereof.The above-mentioned towing rope 11 may be a rope rope or a synthetic fiber rope.

In the case of casting nets, depending on the scale of the fishing gear, it is possible to drop the buoyant body 12, the net end rope 9, and a part of the net end portion 7 into the sea and tow it, and then release the holding line at any position. Then the net casting begins. Also, towing line 1
1 may be provided with a separate direct winding winch without being wound around the purse winch 2' as shown in FIG. It may be provided.

As described above, the net boat A starts casting the net, and after dropping the center part of the net, the berth winch 2'
At this point, winding up of the towing line 11 is started (see Figure 6).During this time, net boat A continues to cast the net, so the towing line 11 approaches the vessel as shown in Figure 6 from P→Q→R. It is captured.

At the same time as the casting of the net is completed, or at an arbitrary time interval, the net edge portion 7 arrives at the position of the purse block 3'' of the purse davit 3. At this point, the net edge portion is moved to a position on the outside side of the purse davit 3 and secured. At the same time, the edges of the respective ends of the towing line 11 and the ring line 5 are cut from the net end portion 7, the ring line 5 is connected to the end of the towing line 11, and winding is continued by the purse winch 2'. will be started.

By using the above-mentioned operating method, the ends of the nets that are to be collected by the net boat are always connected to the net boat, so there are no errors in collection by the retsuco boat, and there is no need to use a retsuco boat at all. Therefore, it has excellent features such as being able to cast nets even in extremely rough sea conditions, improving operational efficiency and, by extension, improving fishing efficiency.

Claims (1)

[Claims] 1 One end of a ring line that runs through a ring attached to the hem of a purse seine fishing gear is removably tied to the end of the net of the purse seine gear, and when casting a net for this purse seine fishing gear, this line is attached separately from the ring line. At the same time, the towing line to be dropped is also removably connected to the end of the net, and then the net is cast.The towing line is hoisted into the ship from the middle of the net casting work, and the fish-catching end, which is the end of the net, is recovered into the ship. A method for operating a purse seine characterized by not using a retsuko boat or an alternative net end holder.
