Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[Industrial Application Field] The present invention is based on the premise of advanced utilization of shark resources which are frequently caused by fishery damage and personal injury related to resource increase due to low use resources. It relates to efficient fishing methods. At the same time, the above-mentioned damages and accidents are eliminated by achieving resource reduction through fishing.

[0002]

2. Description of the Related Art Sharks are widely used in sharks in the coastal and offshore areas during the period of high demand, and shark longline fisheries are mainly used for sharks. Bycatch and landed.

[0003] Except for some regions where these catches are eaten raw or unbaked, they are mainly used as materials for kneaded products, and as special materials such as shark fins and liver oil, such as fins and liver. Site was actively used. Under such circumstances, sharks were established as fisheries even if they were the main target, and as a result, thinning by catching was aggressively carried out, and the stock rarely increased. In the past, fishery damage and personal injury had hardly occurred in the shallow waters off the coast of Japan or offshore.

[0004] However, changes in consumer needs for marine products and the diversification or bycatch of sharks are low in freshness, and the development and import of new paste products have led to a sharp decrease in demand for sharks and an increase in prices. Due to sluggishness, no highly efficient fishing method has been developed to compensate for the decline, and there is a relative income difference from fisheries targeting other fish species as the main catch, and the fishery targeting sharks has declined. did. Under these circumstances, the supply of kneaded product materials became unstable, which further reduced stable demand. The demand for sharks, which still exist, is largely covered by bycatch and landing by existing fishing gear and fishing methods.

[0005] When demand decreases and prices decrease,
Especially in the coastal and offshore areas, bycatch of sharks does not even land the fish, and the fish are discarded after cutting off only the fins.
Under such circumstances, active fishing will not be carried out.
As a result, shark resources at the top of the food chain continue to increase, as the stocks of fish are reduced and the thinning rate due to fishing, that is, the fishing mortality rate, is decreasing. ) Occupies an extremely high proportion compared to actively harvested resources, which is not irrelevant to the above-mentioned damages and accidents. There is a demand for the development of highly efficient fishing gear for that purpose as well as methods of using it as a protein resource, including its countermeasures.

[0006]

As described above, shark resources are increasing due to low use and aggressive fishing, but fish species to be harvested at fishing grounds are irrespective of fishing or recreational fishing. Fishery damage has occurred, such as reduced catches caused by the emergence of sharks and escape by sharks during fishing. Not only that, but also important is that the increase in large sharks is likely to occur frequently during the swimming or diving activities, and there are already accidents. At present, fishing and fisheries including longlines, fixed nets, trawls, etc. are mainly caught by tuna longlines and net fisheries.
Large basket nets have been devised, but have not been put into practical use. Although it can be said that there is no specialized fishery or active fishing methods in this way, fishing gear with high catching efficiency is desired since advanced utilization as a protein source will promote the elimination of the damages and accidents as a result. ing. But such fishing gear
There is no fishing method at present.

[0007]

Means for Solving the Problems Sharks, which are the main target fish species in the present invention, are large and reach a length of 3 to 5 m or more. However, even if the price varies depending on the species, none of them is inexpensive at present. So the operation is simple and low cost,
It is an essential condition that advanced technology and large vessels are not required. For this reason, here, a balun fishing gear was used to solve the above-mentioned problems. The use of explosives as fishing means is prohibited by law, but this fishing gear according to the present invention is an operation within the equipment, and is one of the purports of the ban. It does not indiscriminately kill large groups of fish and large fish species in their infancy, and does not fall under the equipment structure.

[0008]

[Effects] Most fish-eating fish capture food by mouth and swallow without chewing. In the case of fish with teeth, the stomach contents of the fish showed that there was only a slight bite mark by the teeth for capture. To the extent that it is perceived, teeth play a greater role in capture than in chewing. Thus, excluding certain fish, the maximum size of the prey fish, i.e., the bait, is largely determined by the size of its prey rather than its size.

[0009] However, most sharks have a different predation ecology than other fish because the predatory fish is bitter when the predatory fish is large, but if the predatory fish is of a size or type that can be swallowed, it will be other fish. The bait caught as a seed is swallowed without chewing. Even if it is a piece of chopped meat, it is swallowed without chewing as described above.

The specific gravity of an individual in a fish varies slightly depending on the species, but is approximately 1.06 to 1.09, which is slightly heavier than water, and most of the fish are adjusted by adjusting the volume of the bladder to change the specific gravity. Although it keeps its body at any depth, sharks do not have bladders. However, the internal organs, especially the liver, are large, and the buoyancy of the contained oil plays a role in addition to the liver function, and the specific gravity is maintained regardless of the water depth (water pressure). In any case, a normal life is maintained by keeping the specific gravity of the fish at a certain value.

Therefore, the balun fishing gear according to the present invention is buried in small fish or the like as bait by utilizing the above-mentioned predatory ecology in order to forcibly reduce the specific gravity of the fish (to generate buoyancy). The balun inflating device is swallowed with food and swallowed. After reaching the stomach, it is activated to generate gas, and the balun inflates to generate buoyancy to float on the water surface.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. FIG. 1 is a top view, a side view, and a bottom view of the fishing gear in a folded state [I] and a state in which a gas is generated by operating the fishing gear and a balun is expanded [II]. In the side view of the folded state shown in [I] and its sectional view in FIG.
In claim 1, as shown in FIG. 4D, the present device charged in a small fish serving as a bait is used as a float for suspension.
8 into the sea together with the cord of No. 8 and swallow it, and swallow it deeply, or by itself, the 15 pistons shown in FIG.
The pressure-resistant spring 4 is contracted and pierced into the cylinder 2 by means of twelve projections, and gas is ejected to expand the balun to generate buoyancy.

According to the second aspect of the present invention, a cord having an appropriate thickness (strength) and length is attached to a ring attached to the operating rod 9 and a float having an appropriate buoyancy is attached to the other end. As shown in FIG. 4D, the fish is buried in small fish or the like serving as food and thrown into the sea. As soon as it is thrown, it is suspended at the depth of the water by the float attached to one end of the cord. The depth of the suspended water can be easily adjusted by adjusting the length of the cord, and this is the same for the equipment falling under “Claim 1”. Since the swimming depth is so shallow that it is exposed above the water surface, the cord does not need to be so long.

Then, when the bait embedded with the device is swallowed by eating and swallowing, and the cord is towed, the spring of 6 is contracted by the resistance of the float shown at 27, and the device is operated with the fulcrum as a fulcrum. Is pierced and gas gushes out. As a result, the folded one balun expands as shown in the side view of [II] of FIG. 1 to generate buoyancy.

In claim 1 and claim 2, the gas for obtaining buoyancy is obtained by a compressed gas or a liquefied gas. In claim 3, a method for obtaining buoyancy by a gas generated by a gas generating agent is used. is there. Schematically as shown in FIG. 3C, 15 pistons are operated by pressurization with water pressure after swallowing and swallowing, and 14 pressure-resistant springs are contracted to energize 13 as shown in FIG. The 19 contacts are actuated by the projections, and electricity is supplied from 17 batteries to 21 contacts.
The Nichrome wire is ignited and burned by heating to achieve gas generation. Further, the object can be attained by adopting a structure in which electricity is supplied by traction according to claim 2. In either method, the same action is performed after swallowing and gas generation, which is a fundamental feature of the content of the present patent. E, F, and G are shown in a schematic diagram in the order of FIG. 4 in the actual process, and eventually float on the water surface, so that the accommodation becomes easy. It should be noted that even in a method in which gas is directly blown into the inside without using a balun, artificial addition of buoyancy is basically included in the content of this patent since there is basically no change.

[0016]

As described above, the present invention has the following effects. (1) The starting point for shark resources, etc., which are underutilized, can be used as highly utilized resources. (2) A stable supply of sharks as a high freshness material for processed foods and the like can be achieved. It can also be applied as fishing gear targeting three large other fish species. 4 Indirectly and directly assist the promotion of coastal fisheries. 5 By using high utilization resources, control of fishery damage, especially personal injury, can be expected.
