  In the capture of aquatic floating organisms such as jellyfish, a device that is easy to carry and handle, with improved capture efficiency while suppressing damage to living organisms.

There were the following problems.
(B) In capturing fragile aquatic organisms such as jellyfish, it is important to avoid damaging the living body as much as possible. The damage of the living body makes it difficult to maintain the form in subsequent breeding, and significantly reduces the survival rate. In other words, when capturing fragile aquatic organisms such as jellyfish, it is desirable to scoop up organisms with water, and it is not possible to use tools that have holes or gaps through which water flows out, such as nets and pestle.
(B) When capturing aquatic floating organisms that can be seen in the water, the target aquatic suspended organisms will not reach the target aquatic organisms even if they use tools with existing vessels such as scabs, or they will easily flow out of the vessel edge with water. The capture efficiency is not good.
(C) In the capture of aquatic floating organisms that can be seen underwater from a scaffold that is far from the draft, even when a tool with a tool such as an existing handle is attached to the end of a long stick, It is not easy to scoop up aquatic organisms from the surface of the vessel without drawing them off the edge of the vessel.
(D) A tool that captures aquatic floating organisms at the water's edge, whether day or night, should be easy to carry in consideration of safety and easy to handle.
The problem was to solve the above problems.

The aquatic floating organism capturing device for capturing aquatic floating organisms that are visually recognized in the water from above the water includes a heel part 1, an extension part 2, an attachment part 4, and an opening 10. The trap has an attaching part 4 in the form of a removable screw type or a fitting type in the vicinity of the edge center 3 of the extension part at the end of the existing fishing net handle 13 that can be stretched. By connecting to an existing fishing net 13, carrying and handling becomes easy. In addition, it is possible to capture the living organism of floating aquatic life that can be seen floating in the water together with the water, and then draw it up and draw it vertically from the draft surface at the foot and accommodate it. Moreover, the said trap is extended in the substantially 1/4 spherical shape or the substantially dome shape so that a part of upper end periphery of the collar part 1 may be touched and the upper part of the concave surface of the collar part 1 may be covered. By arranging the extending portion 2, the structure is such that when the trap is drawn near the surface of the water, the inflow of water into the trap is suppressed and the aquatic suspended organisms are difficult to flow out. A feature of the structure in which aquatic floating organisms do not flow out is that the length of the edge 6 of the exposed heel portion of the opening 10 is shorter than the length of the edge 7 of the extended portion. In addition, the angle at the joint point 8 between the edge 6 of the flange portion and the edge 7 of the extended portion in the opening 10 is 30 degrees from a substantially right angle, and the vicinity of the joint point 8 forms a taper or a round. Further, the edge 6 of the heel portion has a shape substantially perpendicular to the axial direction of the existing fishing net handle 13 attached to the attachment portion 4, and the size of the opening 10 is the size of the heel portion 1. And occupy approximately ¼ to 1/10 of the total outer area of the extended portion 2 and the opening 10.
When capturing fragile aquatic organisms such as jellyfish, it is desirable to scoop water and aquatic organisms together. The aquatic suspended organism capture device has no mesh, holes, or gaps except for the opening 10 in order to suppress damage due to inflow and outflow of water when capturing aquatic suspended organisms. Furthermore, when processing the member of the trap, the surface of the edge 6 and the extended portion 7 exposed at the opening 10 is deburred or polished, or the edge is bent, or By applying a smooth protective process such as coating with silicon resin, rubber, petrochemical products, etc., the abrasion and damage to the living body due to contact between the edge of the opening 10 and the aquatic suspended organisms can be reduced, and the living body after capture To maintain the shape and improve the survival rate.
In order to stably place the aquatic suspended organism trapping device, a flat surface portion 9 is provided on the bottom surface or a part of the side surface of the trapping device. Further, when capturing aquatic floating organisms at night, in order to make it easier to visually recognize and capture aquatic suspended organisms from the water, the waterproof lighting fixture 15 is attached to the existing fishing rod net connected to the aquatic suspended organism trap. Install and light up to increase efficiency.

  The aquatic suspended organism catcher of the present invention can easily connect a visible aquatic suspended organism living in the water from the safe landing on the coastal scaffolding or from the ship to the tip of the existing fishing net handle and damage it. It can be captured in the absence or significantly reduced state. In addition, as shown in FIG. 4, when the aquatic suspended organisms are accommodated using the trap, when attracted by the characteristics of the shape having the heel part 1 and the dome-like extension part 2, which are different from the case using the handle pallet or the like. In addition, the inflow of water that causes the aquatic suspended organisms captured from the outside to the inside of the trap is prevented. And at the time of uptake | capture, since the capture organisms are settled in the collar part 1 and can be accommodated vertically from the water surface, the efficiency of capture and accommodation is improved and practical. The organisms that have been captured using the aquatic suspended organism trapping device so far are jellyfish of the same size as or smaller than the inner diameter of the trapping device, and swimming swallows, polychaetes, worms, etc.・ Various types such as crustacean larvae and fish larvae. Examples of jellyfish include aquariums such as moon jellyfish, red jellyfish, snail jellyfish, andon jellyfish, urashima jellyfish, camellia jellyfish, octopus jellyfish, duffle jellyfish, human jellyfish, caraca jellyfish, combed sage jellyfish, horned jellyfish, butterfly jellyfish, jellyfish jellyfish, and jellyfish It has a track record of capturing in good condition suitable for exhibitions, viewing and experiments.
