Description

Fish culture cage

One, technical field

The utility model relates to a kind of apparatus of breeding fish, particularly a kind of fish culture cage that is used for fish culture in net pen.

Two, background technology

Pisciculture is a kind of industry with long history in China, is to put in a suitable place to breed by the pond in the past, but bad salvaging and feeding, for ease of salvaging and feeding, most at present employing fish cultures in net pen.Adopt the plastic ties braiding to form but the device net cage of fish culture in net pen is most, therefore destroyed by aquatic rodents such as water rats easily, or drawn disconnectedly by other sharp-pointed article, in case bitten or draw broken suspension case rope, the fish in the net cage will be run away and be caused serious economy loss.

Three, summary of the invention

The purpose of this utility model is intended to overcome the deficiencies in the prior art, provides a kind of simple in structure, easily manufactured, is convenient to fish for and feeding, and is difficult for being bitten broken by aquatic rodent or being drawn disconnected fish culture cage by sharp-pointed article.

The utility model adopts such technical scheme: a kind of fish culture cage, be characterized in including fish culture box, the fishing case, cross cage, fish culture box is a hexahedron, six faces are netted that wire constitutes, in its front, the back, be provided with V-shaped must in casing that constitutes by a plurality of fins in netted 1/3 area on the left side, the fishing case is set in the right-hand member of fish culture box, the left side of fishing case, right-hand member is provided with gate, the right-hand member of fishing case connects firmly near the right side of fish culture box, the middle and upper part, the right side of fish culture box has the hole, cross an end of cage and the hole communications and liaison on the fish culture box right side, the other end is vacant, be installed with on crossing around cage and the fish culture box communications and liaison end funnel that fin constitutes fall must, funnel fall must osculum in crossing cage.

The fish culture cage that provides by the utility model, be placed on rivers, in the lake, place fry in the net of breeding fish, by top mesh feeding, fry grows in fish culture box, and can feed by collecting the outer natural resources (fish) of net cage in the net cage effectively, because of being provided with down palpus, during to a certain size, fish can not run out of yet in the case.During fishing, the gate of mentioning fishing case left end, and feeding in the fishing case, attract the shoal of fish to enter in the fishing case, treat the fish gathering more for a long time, close the gate of fishing case left end, the gate of mentioning right-hand member, the shoal of fish enters the cage of crossing with fish culture box right side communications and liaison by the fishing case, and from the fish that the other end tipping of crossing cage is caught, the falling can to prevent to enter the fish of desiring in it to catch of fishing case setting runs out of again.The utility model is simple in structure, and is easily manufactured, conveniently fishes for and feeding, owing to adopt the wire wire side, is difficult for being stung bad by aquatic rodent or drawn disconnectedly, durable in use by sharp-pointed article, and the group provides safety guarantee to breed fish.
