Description

Jellyfish separated discharging and removal net for reducing fisheries damage}

The present invention relates to a fishing net structure for discharging the jellyfish that is caught with the fish during the operation using a bag-shaped net separated from the fish, jellyfish separation network to form a funnel passage with one of the net of the bag-shaped net On the other hand, as the rear end of the jellyfish separation network is connected to the jellyfish outlet of the form in which the net plate is cut in the longitudinal direction, while simplifying the structure of the fishing net to provide a more economical fishing net, fish and jellyfish The present invention relates to a separation and removal network for reducing jellyfish damage, which enables the effective separation of fish and prevents the escape of fish, thereby enabling a substantial increase in catches.

In general, an operation method using a bag net such as a trawl fishing, a low net, an eye net, or a bag net, as shown in FIG. 1, is formed of a bag net in which the back plate 11, the bottom plate, and the side plate 12 are integrally formed. 10) is released to the place where the various fish groups are formed, and then the bag-shaped net (10) released in this way to the fishing net side by using the vessel (1) or in the state fixed the fishing gear, bag-shaped net (10) Into the inside of the fish is to be trapped in the end of the rear end (13).

In recent years, however, jellyfish have appeared in coastal waters in large quantities in the summer months due to changes in the marine environment, causing massive damage to fishery. It is represented in various forms in almost all fisheries, including fishing trolls, low nets, Ahngang nets, Kwon Hyun nets, nangjang nets, yew nets, as well as trap fishing nets, political nets, and foot nets. In the operation mode, jellyfish are very easily caught with fish, causing a lot of damage.

In other words, when jellyfish are mixed with fish into the bag net 10 during the operation using the bag net 10, the resistance of the fishing gear in the process of enveloping the bag net 10 by the vessel 1 is caused. This greatly increases the variety of fishing gear including the bag net 10, or a large amount of jellyfish block the net of the end 13, that is, the hole of the net to inhibit seawater circulation to reduce the catch, or jellyfish It causes a number of problems such as the loss of fish due to the death of fish and the damage of fish by jellyfish.

In addition, there was a problem in that the fishing environment is further deteriorated because it takes a considerable time to separate the fish and jellyfish from the catches caught by the bag net 10 by manpower, and the separation of the jellyfish. During the work, the worker's skin was exposed to the poison of the jellyfish, which caused secondary problems such as damaging the human body.In the case of too much jellyfish appearing due to these various factors, Cases are also frequent.

As described above, in order to solve various problems caused by the jellyfish's capture in the operation process using the bag net (10), the fishing net for the separate discharge of the jellyfish in the front end 13 of the bag net (10) ( By installing 20, it is possible to effectively separate the jellyfish that are caught with the fish, and to minimize the amount of fish discharged with the jellyfish, thereby reducing the fishing damage caused by the jellyfish's catching and operating. It is known and filed by the applicant of the present application to maximize the efficiency.

The above-mentioned applications include 2005 Patent Application No. 40786 (Application Date: May 16, 2005) and Patent Registration No. 518361 (Registration Date: September 23, 2005), and 2006 Patent Application No. 50024 (Application Date: June 2, 2006) and Patent No. 646453 (Registration date: November 8, 2006), 2007 Patent Application No. 73922 (Application Date: July 24, 2007) and Patent Registration No. 779591 (Registration date: November 20, 2007), 2008 Patent Application No. 51671 (Application Date: June 2, 2008) and Patent Registration No. 868526 (Registration Date: November 6, 2008) And 2009 Patent Application No. 59898 (Application Date: July 1, 2009) and Patent Registration No. 925880 (Registration Date: November 2, 2009).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The fishing net 20, which is a separate discharge and removal net for reducing jellyfish damage of the present invention, as in the case of the previous application, the back plate 11 and the bottom plate 14 are provided up and down, and the side plate 12 is integrally connected to both sides. In the bag net 10 to form the end 13 at the rear end, it is installed inside the bag net 10 corresponding to the front side of the end 13, to avoid the complexity of the drawing In order to form a bag net 10, that is, the back plate 11 and the bottom plate 14 and the side plate 12 itself is omitted.

In addition, in the case of the fishing net 20 according to the present invention as well, it is difficult to achieve any fixed shape due to the structural characteristics of the net, in the following description with reference to the accompanying drawings to help the understanding of the present invention The jellyfish damage reduction fishing net 20 and a part of the bag-shaped net 10 including the same according to the invention will be described as having a fixed shape.

Jellyfish separate discharge and removal fishing net 20 according to the first embodiment of the present invention, as shown in Figures 2 to 5, respectively, in the funnel shape toward the rear side from the back plate 11 and the side plate 12 Jellyfish separation net 21 is installed inclined downward and the jellyfish outlet 22 formed in the longitudinal direction of the bottom plate 14 of the bag-shaped net 10 to be connected to the rear end of the jellyfish separation net 21 in the longitudinal direction Is done.

The jellyfish separation net 21 is subdivided into a pair of side separation nets 24 located inside the upper separation net 23 and the side plate 12 located at the bottom of the back plate 11, as shown in FIG. As mentioned above, this is to illustrate and explain the structure of the fishing net 20 more easily, and the characteristics of the net cannot be regarded as being standardized in the shape shown in FIG. Along the inside of the trunk of the bag net 10 can be a shape close to the cylindrical funnel.

In addition, the front end side of the jellyfish separation net 21 is connected to the back plate 11 and the side plate 12 of the bag-shaped net 10, the lower end of both sides of the jellyfish separation net 21 is a bag net (10) By being installed along the bottom plate 14 of), the jellyfish separating net 21 and the jellyfish outlet 22 together with the bottom plate 14 of the bag net 10 provide a funneled passageway for separate discharge of the jellyfish. do.

In other words, the front end sides of the upper separation net 23 and the side separation net 24 are engaged with the back plate 11 and the side plate 12 of the bag net 10, while the lower end of each side separation net 24. Is coupled to the bottom plate 14 of the bag net 10, the rear end of the upper separation net 23 is bound to the end of the jellyfish outlet 22, while the lower end of the rear end of the side separation net 24 is By being bound to the left and right portions, respectively, along the longitudinal direction of the jellyfish outlet 22, the jellyfish separation network 21 and the base plate 14 form a funnel passageway, while the jellyfish outlet 22 is the last of the passage. It will perform the exit function.

The jellyfish separation network 21 serves as a fish passage and jellyfish separation membrane that prevents the jellyfish, which is a larger object than the fish, from passing through the corresponding net, and allows the fish to pass through the corresponding net. By performing, it is preferable to make the size of the mesh, that is, the size of the net hole (length and length of the side) within the range of 20 to 40 cm, but according to the type of fish species to be caught, The mesh size can be adjusted arbitrarily.

In addition, the angle of inclination toward the bottom plate 14 of the jellyfish separation net 21 is preferably made to form an angle of about 10 ㅁ 5 ,, which is because of the preliminary force of the bag net 10 and By preventing the rear end of the jellyfish separation network 21 from being excessively pushed over by the input of the jellyfish, the jellyfish does not accumulate at the rear end of the jellyfish separation network 21 and is easily discharged along the jellyfish outlet 22. This is because the minimum inclination angle that can be maintained can be maintained.

As shown in FIG. 6 as a component corresponding to another essential part of the present invention, a reinforcing frame for reinforcing the net strength along the periphery of the jellyfish outlet 22 formed by cutting the base plate 14 in the longitudinal direction ( 25), the cutting network 26 for cutting and discharging jellyfish is installed in the jellyfish outlet 22, and the incision length of the jellyfish outlet 22 is preferably within the range of 2 to 3 m. It can be adjusted according to the type and number of individuals.

The reinforcing frame 25 does not have the phenomenon that the jellyfish outlet 22 formed by cutting the net of the base plate 14 becomes tattered in the continuous discharge process of the jellyfish or the net is torn in the process of temporarily discharging an excessive amount of jellyfish. By preventing the jellyfish outlet 22 is formed so as to form a wider path than necessary to provide a factor of escape of fish, by placing a thick rope or the like along the periphery of the jellyfish outlet 22, and then the base plate (14) It is most preferable to use it by binding firmly with a net.

On the other hand, the cutting network 26 is used for the relief of jellyfish by cutting and discharging jellyfish pushed down along the jellyfish separation network 21 to a certain size by using the resistance according to the preliminary network of the bag-like net 10 as in the case of the first application It is most preferable to use a high-strength cutting chamber capable of cutting the jellyfish even though its diameter is very thin, and if necessary, the cutting net 26 is reversed into a bag shape as shown in FIG. It is also possible to install hanging on the bottom of the jellyfish outlet 22.

Hereinafter, the working relationship of the present invention having the above configuration will be described in detail with reference to FIGS. 6 and 7 of the accompanying drawings, and in the description of the working relationship of the present invention except for the contents mentioned in the prior application, The following description will focus on the components corresponding to the essential parts of the description.

On the other hand, in Figure 7 is installed in the form of the end hanging on the bottom plate 14 of the bag net 10 is an experimental catching net 27 for checking the escape amount of the fish through the jellyfish outlet 22, bag net In the actual operation using the (10) is to be used to remove the experimental catching net (27).

First, after winding the bag-shaped net 10 is installed on both nets of the ship 1, the fishing net 20 is installed according to the first embodiment of the present invention, and then using the fish finder to determine the location of the fish group to capture, After releasing the bag-shaped net 10 installed with the jellyfish damage reduction fishing net 20 according to the present invention, the bag-shaped net 10 released as described above is predicted to the fish group using the vessel 1.

When the fishing net 20 according to the first embodiment of the present invention as described above is expected to the fish group side, when the number of jellyfish population such as summer season, a large amount of jellyfish together with fish Entering the inside of the net (10), the fish and jellyfish introduced into the inside of the bag-shaped net 10 is primarily guided through the wide inlet provided by the jellyfish separation net 21 and the base plate (14).

Among the fish and jellyfish primarily induced through the inlet provided by the jellyfish separation network 21 and the bottom plate 14 as described above, the fish passes through the jellyfish separation network 21 having a wide mesh eye, and then ends 13. ) Is led to the inside of the jellyfish, in the case of jellyfish is guided to the bottom plate 14 side along the jellyfish separation net 21 by the preliminary force of the bag-shaped net 10, and then the jellyfish outlet 22 provided in the bottom plate 14 And it is cut out and discharged out of the bag-shaped net 10 via the cutting net 26.

During the operation process as described above, the fishing net 20 of the present invention can more effectively and effectively block the escape of fish in the process of separating the fish and jellyfish by the structural features of the jellyfish outlet 22, the reason is that jellyfish This is because the outlet port 22 is formed to be cut in the longitudinal direction of the base plate 14.

In other words, the hydraulic resistance generated when the bag net 10 is expected to act in a direction parallel to the jellyfish discharge port 22. This hydraulic resistance shows the jellyfish discharge port 22 in FIG. It provides the force to maintain the closed state as shown, the jellyfish outlet 22 is shown in Figure 6 (b) by the jellyfish's input only when the jellyfish is pushed along the jellyfish separation network 21. It is going to happen.

Thus, as long as the jellyfish is introduced into the bag-shaped net 10 and is not pushed into the jellyfish outlet 22 along the jellyfish separation network 21, the jellyfish outlet 22 is always provided by the hydraulic resistance according to the flow of seawater. By maintaining the closed state, it is possible to prevent the escape of the fish through the jellyfish outlet 22 more actively and effectively, it is possible to ensure a substantial increase in the catch while performing the separation function of the fish and jellyfish It is.

As a result of testing the escape of the fish using the bag net 10 attached to the experimental catching net 27 as shown in Figure 7, the end 13 is only caught fish and the experimental catching net (27) ), Only jellyfish were introduced, and sometimes a very small number of fish were included with the jellyfish in the experimental catch network (27), but this was anesthetized by the jellyfish tentacles and lost the swimming ability with the jellyfish. It was introduced into the experimental catching net (27), it was found that the fish with the swimming ability did not enter the experimental catching net (27) through the jellyfish outlet (22).

In the same manner as described above, unlike in the case of the previous application, the escape of the fish is achieved only by optimizing the shape of the jellyfish outlet 22 without applying a separate means to prevent the escape of the fish to the fishing net 20. Since it can be blocked more actively and effectively, the structure of the fishing net 20 for the separation of fish and jellyfish can be greatly simplified with only the jellyfish separation network 21 and the jellyfish outlet 22.

Due to this, by significantly reducing the manufacturing and maintenance costs of the bag-shaped net 10 including the fishing net 20 compared to the previous application, of course, it is possible to further reduce the economic burden of small fisherman, By zeroing the escape rate of the fish during the operation using the bag net 10 (Zero) will be able to contribute to the actual income increase of the fisherman by increasing the catch.
