Description

Water surface for aquaculture trapping thorn Barb fish device

Technical field

The present invention relates to a kind of fish device, particularly a kind of water surface for aquaculture trapping thorn Barb fish device, belongs to fish-catching apparatus technical field.

Background technology

Thorn Barb fish is commonly called as blue or green rod, grass carp, Huang Juanyu etc.Thorn Barb side scale base portion respectively has a blackspot, the outer of its dorsal fin studs with black surround, thorn Barb likes living in water colour clear water territory, it is ominivore-fish, staple food aquatic insect and other water plants, juvenile fish stage ingestion animal erbium material is more, egg-laying time is 4 annual ~ May, the environment of flowing water is needed when laying eggs, speed of production is general, mainly be distributed in the Min River, Yuanjiang, the Bei Jiang of the Qiantang River and the Zhujiang River, Xijiang River Water System, hangnail Barb is the same with thorn Barb class, inhabit in rivers flowing water, phytophagy, the chip etc. of the thread algae insect of staple food and plant, sexual maturity 3 ~ 4 age, egg-laying time is 4 ~ June, ovum buoyancy, growth rate is general, general individual about 1kg, common edible fishes, be distributed in Yuanjiang, the ground such as the Bei Jiang basin of Pearl River system and Hainan Province.

At present, people, when fishing for thorn Barb fish, are generally use traditional drawing in the net, trawlnet, revolve net, lift the Fishing tools such as net, but, due to the waters bottom complex structure in affiliated waters, pasture and water in the water surface from the restriction waiting barrier more, and the physiological life habit of fish is different in addition, and the temperature difference of described north-south climate is different, reservoir, great river, big lake, water quality existing for water surface for aquaculture is different, the temperature difference respectively has difference, water column structure is different from the depth of shape and structure, namely situation is also had nothing in common with each other to cause that the fish in each waters are looked for food etc., so the fish using traditional instrument to fish for water surface for aquaculture are just difficult to reach desirable fishing efficiency, want to reach desirable fishing efficiency, according to the characteristic of fish, different cage tools will be selected, netting gear, device and net cage, then according to the dietary habit of various fish, sound passes principle and mechanics, selects to be applicable to the desirable cage tool of fishing efficiency, netting gear, device, net cages etc. just can reach convenient, fast, desirable fishing efficiency.

Summary of the invention

The object of the invention is to: provide a kind of labour intensity little, catch that thorn Barb fish is not frightened, institute catch thorn Barb fish injured less, do not affect its normal growth, quantity of the catch many, catch the effective a kind of water surface for aquaculture trapping thorn Barb fish device of thorn Barb fish, overcome existing netting gear water surface for aquaculture fish for sting Barb fish time existing above-mentioned defect.

The technical solution adopted for the present invention to solve the technical problems is: a kind of water surface for aquaculture trapping thorn Barb fish device comprises hello the fish box that leader surrounds, described hello fish box, fish-collecting box, fish-taking box has leader completely encircle, hello the fish box of described leader completely encircle, fish-collecting box, before fish-taking box is respectively arranged with, in, rear sliding door, before, in, before the middle part at rear sliding door two ends is respectively connected with one respectively, in, rear sliding door rope, before, in, rear sliding door is front, in, switch back and forth can be realized under the effect of rear sliding door rope, described fish-taking box is long narrow shape casing, fish-taking box bottom half is coated with spacer screen, spacer screen covers fish-taking box lateral surface from bottom fish-taking box to fish-taking box extension, nettle has been connected with corner in the middle part of described spacer screen, spacer screen is to play to realize spacer screen under nettle up and down in fish-taking box casing.

The present invention is achieved in that and selects the required water surface, trapping thorn Barb fish device is installed in the water surface chosen, after installing, every day at regular time and quantity feeding in fish box fish meal of throwing something and feeding, the apartment house district of thorn Barb fish can be formed after throwing something and feeding tens days, because thorn Barb fish can send a kind of food ultrasonic when eating fish meal, thorn Barb fish within circumference km can be focused on feed in fish box and take food, thorn Barb fish once get used to eating fish meal in hello fish box, just define conditioned reflex, they have food to eat once understanding is fed in fish box everyday, hello fish box will attract more to sting Barb fish and come to eat food, just define natural natural fish news, after fish news to be formed, can by requirement timing once a day or once fish for several days, during fishing, observe to enter to feed and enter fish quantity in fish box, front sliding door can be closed after reaching the amount of catching, make the thorn Barb fish fed outside fish box freely movable, feed fish box and stop feeding, then middle sliding door is opened, fish is allowed to enter fish-collecting box, fish-collecting box is pulled in closing after entering completely to sting Barb fish, then rear sliding door is opened, fish is allowed to enter fish-taking box, fish-taking box has pulled nettle after entering full rear closedown, namely spacer screen is mentioned in the middle part of net cage from fish-taking box, can fish with fishing net, so repeatedly operate, after reaching the amount of catching, sliding door and middle sliding door after closing, open front sliding door, allow fish normally pass in and out and feed fish box, every day, timing was thrown something and fed fish meal equally, when need to catch again when catching.

Beneficial effect of the present invention: as can be seen from such scheme, the present invention have labour intensity little, catch that thorn Barb fish is not frightened, institute catch thorn Barb fish injured less, do not affect its normal growth, quantity of the catch many, catch and sting the effective advantage of Barb fish, reach object of the present invention, effectively overcome use traditional draw in the net that the labour intensity existing when water surface for aquaculture fishes for thorn Barb fish is large, thorn Barb fish is afraid of one's shadow, thorn Barb fish easily injured, affect its normal growth and the defect of convenient, fast, desirable fishing efficiency cannot be reached.

Below in conjunction with accompanying drawing, the invention will be further described.
