Embodiment Construction

[0009] In specific implementation, such as figure 1 Shown, excavate the fish collection pit 2 at the outlet 3 of the yellow catfish pond 1.

[0010] In specific implementation, such as figure 2 As shown, the upper mouth of the fish collection pit is 10m long, 8m wide, and the lower mouth is 8m long, 6m wide, and 1m high. The excavated fish collection pit is poured with cement walls on all sides, and a section 1 is left at the water inlet. The specification is 1m*0.5m , build honeycomb bricks, and drain water when drying the pond.

[0011] In specific implementation, such as image 3 As shown, the preset net cage is made of 9 strands of 2cm segmented mesh, the upper mouth of the preset net cage is 11m long, 9m wide, the lower mouth 7 is 8m long, 6m wide, and 2m high, and there is a seam drop line around the upper mouth of the net cage , The bottom 2 of the cage is sewed with an "X" shaped drop line.

[0012] During specific implementation, the preset net cage is installed ...

Abstract

The invention discloses a yellow-head catfish pond preset net cage dry-up method, relates to a yellow-head catfish pond dry-up method, and especially relates to a preset net cage dry-up method; the method can prevent anoxic asphyxia, has no damage to the yellow-head catfish, and saves labor cost; a fish gathering pit is arranged on a yellow-head catfish pond water outlet, and surrounded by a casting cement wall; a water inlet is preserved with a 1mX0.5m cross section for building cellular bricks, and the bricks are for draining in a drying pond process. 9 node meshes of 2cm can form the preset net cage; an upper opening of the net cage is sewed with drop lines in surrounding; the bottom of the net cage is sewed with an X-shape drop line; the preset net cage is arranged in the fish gathering pit, and net cage is fully grounded; the surrounding of the net cage opening uses an anchor to insert bottom mud for fixation. In dry-up pond fishing operation, the water draining is stopped until the water level reaches 20cm depth from the preset net cage opening; the net cage opening is pulled up when all yellow-head catfish automatically enter the fish gathering pit preset net cage, thus completing dry-up pond fishing.

Description

technical field [0001] The invention relates to a method for drying ponds of yellow catfish ponds, in particular to a method for presetting net cages for drying ponds. Background technique [0002] In the prior art, it is known that the yellow catfish belongs to the bottom fish, and the catch rate is not high when the net is caught, and it needs to be fished in a dry pond. The traditional method of fishing the yellow catfish in a dry pond is to use a water pump to drain the pond water, so that the breeding The fish enter the Jiyu ditch, and 8-10 workers hand-dip the nets to catch the fish, put them into plastic baskets and carry them away, and put them into the cages in the adjacent pond to complete the fishing in the dry pond. In the process of draining the water body of yellow catfish ponds, hypoxic flooding often occurs, resulting in the death of yellow catfish; when fishing with nets by hand, there is very little water in the fish collection ditch, and fish, mud, and wat...
