Technical Field

The invention relates to an octopus trapping device and method, and belongs to the technical field of marine fishery trapping.

Background

Octopidae (Octopididae, d' Orbigny, 1840) belongs to the Cephalopoda (Cephalopoda), Octagonales (Octopa), commonly known as Octopus, and is the largest group of Cephalopoda. The octopus is widely distributed in the south-north coastal areas of China, wherein two octopus including octopus ocellatus and octopus ocellatus are common economic cephalopods near the sea, are important export objects in China, and have good domestic market foundation. Octopus has both frozen and fresh forms in domestic consumer markets, while fresh needs are predominant abroad, and the markets are mainly in korea and japan.

At present, trawlnets, tanks or shells are mostly used in the traditional capturing tools for offshore octopuses in China, wherein the trawlnets have the greatest damage to octopuses, the octopuses are difficult to obtain due to the fact that the tanks and the shells of the octopuses are smooth in interior, narrow in space and the like, and the octopuses are often broken in wrist, torn in carcass and the like of individuals, so that the quality of wild parents used for capturing and breeding is seriously affected, and the survival rate and the economic benefit of the temporary culture of fresh and alive commodities are greatly reduced. Therefore, the method can effectively avoid the defects in the traditional fishing gear fishing process, and has important practical significance for improving the parent fishing quality, the temporary rearing survival rate and the economic benefit and promoting the sustainable utilization and the healthy development of marine fishery in China.

Disclosure of Invention

The invention provides an octopus trapping device which is used for overcoming the defects that octopus is difficult to obtain and individuals often have wrist breakage and carcass tearing in the prior art.

In order to solve the technical problems, the invention provides the following technical scheme:

the invention discloses an octopus trapping device which comprises a barrel body and a barrel cover, wherein a barrel opening at one end of the barrel body is provided with the barrel cover matched with the barrel opening, the barrel cover is provided with a first rope penetrating hole, the barrel body is attached to the barrel cover through a rope knot on a rope on the outer side of the barrel cover, one side of the barrel body close to the barrel cover is provided with a second rope penetrating hole, the barrel bottom at the other end of the barrel body is provided with a water leakage hole, and the barrel body is provided with a raised particle belt along the inner wall.

The trapping method comprises the following steps:

1) the trapping devices are connected in series at intervals of 0.5-1.5m by ropes, and are thrown to a sea area with octopus captured near the sea in a direction perpendicular to the tide water direction, harvesting is carried out once in about 3 days in the propagation peak period in 9-11 months and 2-4 months in the north and once in about 3-5 days before and after the propagation peak, capturing octopus vulgaris is mainly used in the south, namely harvesting is carried out once in about 2 days in the propagation peak period in 3-6 months and harvesting is carried out once in about 3-5 days before and after the propagation peak;

2) when the device is harvested, the trapping device is lifted out of the water as soon as possible, and the octopus ocellatus or octopus ocellatus can adsorb objects by using the wrist when being stimulated by the outside and is hidden in the trapping device, so that the objects cannot escape from the cylinder body, and the trapping rate is greatly improved;

3) when the octopus is caught, the cylinder cover which is tightly adsorbed by the octopus or the octopus is firstly removed, then the bottom of the trapping device is knocked by an appliance, at the moment, the octopus part stimulated by sound and vibration automatically climbs out of the cylinder body and does not climb out automatically, then the smooth appliance in a stick shape is deeply arranged on one side with a gap of the cylinder body, stimulation is given from the cylinder bottom, the sucking disc of the device cannot be firmly adsorbed by the particle belt on the inner wall of the cylinder body, and the octopus or the octopus can rapidly escape from the trapping device.

Furthermore, the cylinder body is made of any one of stainless steel, UPVC, PVC and fired clay tiles.

Furthermore, the cylinder cover is made of shells, plastic sheets or steel sheets and the like, the shells are scallop shells, the smooth surface faces the direction of the cylinder opening, the plastic is light PVC and has the thickness of 1-1.5mm, and the steel sheets are made of stainless steel and have the thickness of 0.5-1 mm.

Furthermore, the barrel is long cylindrical, so that the problem that the tank and the conch are narrow in space and not easy to take out by tools is solved.

Furthermore, the raised particle belts are arranged in at least 1 circumference, the width is 1-3cm, and the situation that the octopus wrist sucker is tightly adsorbed on the raised particle belts and is difficult to obtain and damage is caused to the octopus wrist sucker due to pulling is avoided.

Furthermore, the height of the granules in the granule belt is 2-6mm, the width of the granules is 2-6mm, and the distance between two adjacent protruding granules is 1-6 mm.

Furthermore, the water leakage holes are at least 1, and the diameter of each water leakage hole is 1-1.5 cm.

Further, the octopus refers to octopus ocellatus and octopus ocellatus.

Further, receive and draw the rope and can let cover lateral shifting, because the limiting displacement of knot can let the cover laminating barrel, can not let the cover keep away from the barrel again.

Further, the rope is a nylon rope or a hemp rope.

Furthermore, the depth of the cylinder body is 7-20cm, the wall thickness is 1-5mm, and the inner diameter of the cylinder opening is 6-15 cm.

Compared with the prior art, the invention has the following beneficial effects: the design of the long cylindrical shape of the device makes up the problems that the space between the tank and the conch is narrow and the tank and the conch are not easy to take out by tools; the device makes up the problem that the inner walls of the cylinder body and the cylinder cover are smooth through the design of the inner particle belt, the octopus wrist sucker is prevented from being tightly adsorbed on the octopus wrist sucker and being difficult to obtain and damaged by pulling the octopus wrist sucker, and the probability of escaping due to physical stimulation in the harvesting process is reduced; the quality problem of breeding used wild parents has been solved to this device, has important meaning to the development scale octopus, the artifical seed breeding of octopus has, can also improve the economic benefits of this commodity transportation, sale, export.
