The present invention will be further described with reference to fig. 1 to 4.

Example 1: the eel fry filtering and catching net shown in fig. 1 to 4 comprises a catching net body 1 which is unfolded to form a horn-shaped barrel, wherein the catching net body 1 comprises a fish inlet end 11 and a fish outlet end 12, a separation net bag 8 is arranged in the catching net body 1 at a position close to the fish outlet end 12, a sealing end 82 of the separation net bag 8 is close to the fish outlet end 12, and net cloth at the periphery of an opening end 84 of the separation net bag is sewn on the net cloth of the catching net body 1;

the fishing net body 1 is sequentially divided into a first-section filtering area 4, a second-section filtering area 3 and a third-section separating area 2 from a fish inlet end 11 to a fish outlet end 12, and the outer diameter of a cylinder of the fishing net body 1 after being unfolded is gradually reduced from the first-section filtering area 4 to the third-section separating area 2; the separation mesh bag 8 is positioned on the section of the filtering area 4;

a strip-shaped hole 83 is formed in the bag body 81 of the separation mesh bag 8, a first zipper 9 is arranged on the fishing net body 1 at a position corresponding to the strip-shaped hole 83 on the mesh cloth in the section of the filtering area 4, and the first zipper 9 can control the opening and closing of the strip-shaped hole 83;

in this embodiment, the zipper tape of the first zipper 9 is sewn on the net cloth of the fishing net body 1, and the bag body of the separation net bag 8 around the strip-shaped hole 83 is sewn on the zipper tape of the first zipper 9.

The fishing net body 1 is provided with a second zipper 10 on the net cloth positioned in the second filtering area 4.

The fishing net body 1 is formed by splicing fishing net cloth, and the splicing connection parts of the fishing net cloth are provided with first reinforcing belts 7. The first strengthening band is arranged along the net body of the fishing net, and is in the same direction with the direction from the fish outlet end to the fish inlet end, the arrangement of the first strengthening band can increase the connection strength of the splicing part of the net cloth, and the first strengthening band is prevented from being broken.

The fishing net body is provided with second reinforcing belts 6 which are staggered up and down alternately at the splicing joint of the two sections of filtering areas 3 and the two sections of filtering areas 4 along the circumference of the splicing joint, the second reinforcing belts can further increase the strength of the joint of the two sections of filtering areas 4 and the two sections of filtering areas 3, the joint can be prevented from being pulled by external force at the same circumference when being stressed, and further the joint can be prevented from being broken due to stress.

The length of the first-stage filtering area 4 is 280-450cm, the length of the second-stage filtering area 3 is 350-600cm, and the length of the third-stage separation area 2 is 1200-1800 cm.

In specific implementation, the three-stage separation area 2 is from the fish outlet end 12 to the open end 84 of the separation mesh bag 8, the two-stage filtration area 3 is from the open end 84 of the separation mesh bag 8 to the second reinforced belt 6, and the one-stage separation area 4 is from the second reinforced belt 6 to the fish inlet end 12.

The maximum width of the opening of the U-shaped notch is 650cm and the length of the U-shaped notch is 600cm and 550 cm.

The U-shaped notch is formed in one section of the filtering area, so that the size of the opening of the fish inlet end can be increased greatly, the fishing efficiency is improved, the fishing net can float upwards and sink along with seawater, and when large storms occur, the periphery of the fish inlet end does not need to jump up and down along with the buoyancy frame, so that the storms resistance of the fishing net can be improved, and the damage rate of the fishing net is reduced.

The invention, in particular use:

four corners of a fish inlet end 11 of the fishing net are respectively fixed on four corners of a rectangular frame with 1.5 multiplied by 6m and buoyancy (provided with floating balls), a U-shaped notch where a pressing weight 5 is positioned below, and a fish outlet end 12 is connected with an eel fry protection bag or a protector; the fishing net is unfolded under the action of seawater, the seawater with impurities such as eel fries, seaweed and the like in the seawater enters the first-section filtering area 4 from the fish inlet end 11, a large amount of seawater flows out from the holes of the net cloth, the impurities such as eel fries, seaweed and the like which are left after filtering pass through the second-section filtering area 3 along with the seawater until the separation net bag 8, the separation net bag 8 intercepts a large amount of impurities such as seaweed and the like, the eel fry is drilled out from the meshes of the separation mesh bag 8 by the drilling characteristic, finally reaches the eel fry protection bag or the eel fry protector through the fish outlet end 12, the catching of the eel fry can be completed, and the sundries such as seaweed and the like trapped in the two-section filtering area 3 can be discharged by opening and closing the second zipper 10, when the sundries such as seaweed and the like trapped in the separation mesh bag 8 reach a certain amount, after a certain pressure is applied to the separation mesh bag 8, the first zipper 9 can be automatically opened, and then sundries trapped in the separation mesh bag 8 can be discharged out of the catching net.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the invention as defined by the appended claims.
