Description
Technical field
The utility model relates to a kind of lamp light trapping fish and lifts net, especially is provided with silver carp bighead fry safe escape designated lane and lifts net with the lamp light trapping fish of dividing the fish device.
Background technology
The lamp light trapping fish is lifted net and is used for night, claims that again light lifts net, and it is wide and long generally to be more than 20 meter, and big has more than 40 meter.Its concrete structure is referring to Fig. 1, and the outlet of fishing net 1 central bottom connects the fishing net string bag 8 removably, and the fishing net string bag 8 bottom openings are tied up with rope; Four jiaos of fishing net 1 lead to the reservoir two sides through steel cable 2, on one side two jiaos tie up on the fixture 3, another side connects on the winch 4 for two jiaos, is used for lifting net; Light supply apparatus comprises the bulb 5 that is positioned at about 1 meter of fishing net centre-height, and through power supplys such as electric wire 6 connection generators 7.
The lamp light trapping fish is lifted net and utilizes the light habit that becomes of animal to attract the biogenic accumulation of a large amount of fish happiness food, and then attracts reservoir silver carp bighead with the gathering of reservoir small fishes and catch.Can overcome the influence of reservoir complex-terrain landforms and reservoir vegetation, be mainly used in and fish for reservoir silver carp bighead and reservoir small fishes etc., because labour intensity simple to operate is low good and generally promote and use at reservoir with fishing result.
But, let fish culture in reservoir operator and workman worried be exactly when adopting lamp attracting to lift the net fishing, after the trapping hauling, the fish of fishing net string bag the inside generally be hundreds of jin to several very heavy between, can reach jin up to ten thousand for a long time.The screening of silver carp bighead fry, silver carp grown bighead carp, small fishes can only be accomplished with separating manually, expend a lot of times and labour, and silver carp bighead fry is caused very big damage, and dead fry phenomenon occurs in a large number, has so just strengthened the loss of reservoir fishing.
The utility model content
In order to solve above-mentioned drawback; The utility model technical problem to be solved is; Provide a kind of lamp light trapping fish to lift net, can in water, fish and separate silver carp bighead fry, silver carp grown bighead carp, small fishes in the operation process automatically, and free silver carp bighead fry; The effectively safety of protection silver carp bighead fry, and reduction labour intensity.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopts is; The light that is provided with branch fish device and silver carp bighead seedling safe escape passage is lifted net, comprises fishing net, the fishing net string bag and light supply apparatus, it is characterized in that; Be provided with one deck fry separate mesh sheet in said fishing net inside, the mesh of said fry separate mesh sheet is greater than the mesh of said fishing net; Said fry separate mesh sheet center is provided with closed second outlet; Be provided with the 3rd outlet at said fishing net near bottom position; The port that between said fishing net bottom and said fry separate mesh sheet, is provided with the said passway for escaping of passway for escaping that surrounded by the net sheet is docked said second outlet, and the lower port of said passway for escaping is docked said the 3rd outlet.
Because fry of silver carp bighead and finished product fish individuality are greater than the reservoir small fishes.Technique scheme utilizes the individual difference in size of silver carp bighead fry, silver carp grown bighead carp, small fishes to realize separating automatically in the fishing operation process in the water.The width of mesh of said fry separate mesh sheet is set to only allow the reservoir small fishes to pass through, and second outlet reaches the port sealing of the passway for escaping that docks with it.The fish that get into said fishing net have the habit of boring escape down, and finished product fish and silver carp bighead fry can't pass through said fry separate mesh sheet, have only small fishes to pass through said fry separate mesh sheet and get in the lower floor and the said fishing net string bag; Open said second outlet after dividing fish to accomplish, the port of the said passway for escaping that docks with second outlet is opened thereupon, and finished product fish and fry are through said second outlet, passway for escaping, the 3rd outlet escape; Last only need the small fishes in the fishing net string bag results to fishing boat by routine operation gets final product.
As a kind of improvement, be provided with at least one annular supports frame in the said passway for escaping, the annular supports frame in the passway for escaping struts passage, guarantees that finished product fish and fry have enough escape spaces, can be not impaired because of reasons such as extruding in the escape process.
In order to realize fishing for of finished product fish on the basis of the above; A kind of improvement as the utility model; Inner at said fishing net; Also be provided with one deck finished product fish separate mesh sheet at least on the said fry separate mesh sheet, the mesh of said fry separate mesh sheet is less than the mesh of the finished product fish separate mesh sheet mesh greater than said fishing net; Said finished product fish separate mesh sheet center is provided with closed the 4th outlet; Said the 3rd outlet connects removably and divides the fishnet pocket.
Because the fry individuality of silver carp bighead is less than the finished product fish but greater than the reservoir small fishes.Above-mentioned improved technical scheme utilizes the individual difference in size of silver carp bighead fry, silver carp grown bighead carp, small fishes to realize separating automatically in the fishing operation process in the water.The width of mesh of said finished product fish separate mesh sheet is set to only allow the reservoir small fishes to pass through for only allowing fry and reservoir small fishes through the width of mesh of, said fry separate mesh sheet, and the port of the 4th outlet, second outlet and the passway for escaping that docks with it is sealed.The fish that get into said fishing net have the habit of boring escape down, and the finished product fish can't be stayed the superiors through said finished product fish separate mesh sheet; Silver carp bighead fry can't be stayed the intermediate layer through said fry separate mesh sheet; Open said second outlet after dividing fish to accomplish; The port of the said passway for escaping that docks with second outlet is opened thereupon, and fry is through said second outlet, passway for escaping, the 3rd outlet escape; Having only small fishes to pass through said fry separate mesh sheet gets in the orlop and the said fishing net string bag; To divide the fishnet pocket to be connected in the 3rd outlet again; Divide the bottom opening of fishnet pocket to tighten; Open said the 4th outlet, the finished product fish falls into branch fishnet pocket through the 4th outlet, second outlet, passway for escaping, the 3rd outlet, and the annular supports frame in the passway for escaping struts passage; Guarantee that fry has enough escape spaces, can be not impaired because of reasons such as extruding in the escape process; Last only the need by routine operation with the fishing net string bag and divide finished product fish and small fishes in the fishnet pocket to gather in the crops to fishing boat to get final product.
As a kind of improvement, the mesh nettle that constitutes said fry separate mesh sheet and/or finished product fish separate mesh sheet is provided with sleeve pipe.It is out-of-date to bore fish, and sleeve pipe rotates, and it is injured or dead to prevent that fish or fry are stuck in the mesh; Also can strengthen the hardness of mesh, prevent to net sheet and damage.Shell material can adopt bamboo wood, plastics or metal etc.
As a kind of preferred, said the 4th outlet and/or second outlet are in-line opening or cross opening.Make easily, seal or open conveniently.
As a kind of preferred, said the 4th outlet and/or the second outlet sealing mode adopt rope to sew up or tie up, and leave slip-knot.
As a kind of preferred, said the 4th outlet and/or the second outlet sealing mode adopt slide fastener.
