Description

Culture system for shrimp pond fish culture

Technical Field

The utility model relates to an aquaculture technical field, in particular to farming systems that shrimp pond cover was bred fish.

Background

The prawn culture is a high-load culture system, and double burdens are caused on substrate and water quality in the culture process, so that the culture water environment is finally deteriorated, and diseases are caused. The fish and shrimp polyculture can fully utilize water resources, reduce disease occurrence and improve the success rate of cultivation. However, the problems of fish and shrimp polyculture mainly include: if the quantity of the mixedly cultured fishes is small, the occurrence of prawn diseases cannot play a role in biological prevention and control, and if the quantity of the mixedly cultured fishes is too large, the fishes can rob high-value prawn feed, so that the ingestion and the growth of the prawns are influenced; the other is that the excrement such as residual bait, excrement and the like generated in the process of prawn culture is more, the biological regulation and control can not be carried out by totally depending on the mixed culture of fish, and a sewage discharge device is required to be arranged.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a farming systems of shrimp pond fish of breeding in set keeps apart the polyculture with shrimp and fish, can play biological prevention and control's effect, can prevent again to mix and breeds the fish and snatch the shrimp fodder to can effectively collect the blowdown to the excrement and urine that the shrimp class produced and handle, water-purifying quality.

The above technical purpose of the present invention can be achieved by the following technical solutions:

a culture system for culturing fish in a shrimp pond in a sleeving way comprises a culture pond, wherein a culture isolation net is arranged in the middle of the culture pond, a sewage collection funnel is arranged at the bottom of the culture pond and downwards in the culture isolation net, the bottom of the sewage collection funnel is communicated with a drain pipe extending out of the culture pond, and the free end of the drain pipe is communicated with a water suction pump; install a plurality of oxygenation waterwheels that float in the surface of water in breeding the pond, each oxygenation waterwheel all includes a plurality of pontoon, rotates and connects in pivot, a plurality of impeller, the drive of installing between two pontoon and being connected with the pivot in the pontoon upper end pivot pivoted driving motor, the rotation direction of all oxygenation waterwheels forms the closed loop.

Through adopting above-mentioned technical scheme, during the breed, breed the shrimp in breeding the pond to breed filter feeding fishes such as tilapia, bighead carp in breeding the median, throw the shrimp fodder for the shrimp at breeding the pond edge, the shrimp can feed the shrimp fodder at the pond edge, and the polyculture fish can not get rid of with the shrimp and snatch in breeding the median, four oxygenation waterwheels rotate and make pond water flow to same direction, produce the swirl, concentrate the incomplete bait excrement and urine that the shrimp produced to breeding the median gradually and swallow the filtration by the polyculture fish in breeding the median, the incomplete bait excrement and urine of remaining in the final a small amount concentrates on in the collection dirt funnel, regularly with the suction pump will collect the incomplete bait excrement and urine in the dirt funnel and take away can.

The utility model discloses a further set up to: the open end of the dirt collecting funnel is provided with a filter screen.

Through adopting above-mentioned technical scheme, less muddy breed fish is along with discharging when preventing the blowdown.

The utility model discloses a further set up to: the pontoon at each oxygenation waterwheel both ends has all seted up the slide opening downwards, and each slide opening all sliding connection has to insert downwards the gag lever post of breed bottom of the pond.

By adopting the technical scheme, when the water level changes, the oxygenation waterwheel can move up and down relative to the limiting rod along with the water level change.

Compared with the prior art, the utility model discloses following beneficial effect has:

firstly, the prawn and the fish are isolated and polycultured, so that the biological prevention and control effect can be achieved, the shrimp feed can be prevented from being eaten by polycultured fish, the breeding water environment is prevented from deteriorating, and the survival rate of the prawn is improved;

two, the utility model discloses a plurality of oxygenation waterwheels are pond water oxygenation, ensure that shrimps can normal growth to a plurality of oxygenation waterwheels rotate the in-process and can produce the swirl, concentrate the incomplete bait excrement and urine that shrimps produced gradually to breed and be swallowed the filtration by the polyculture fish in the isolation network, in the dirty funnel of collection is concentrated to the incomplete bait excrement and urine of remaining in a small amount at last, with polyculture fish water purification, and can also initiatively carry out the blowdown.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The embodiment of the invention relates to a shrimp pond fish culturing system, which comprises a square culturing pond 1, wherein a circle of culturing isolation net 2 is arranged in the middle of the culturing pond 1, a sewage collecting funnel 3 is arranged at the bottom of the culturing pond 1 downwards in the culturing isolation net 2, the open end of the sewage collecting funnel 3 is provided with a layer of filter screen 31, small mixed cultured fish is discharged along with the sewage, the bottom of the sewage collecting funnel 3 is communicated with a sewage discharge pipe 32 extending out of the culturing pond 1, and the free end of the sewage discharge pipe 32 is communicated with a water suction pump 33. Install four oxygenation waterwheels 4 that float in the surface of water in breeding pond 1, and oxygenation waterwheel 4 sets up in the diagonal angle of breeding pond 1, each oxygenation waterwheel 4 all includes five pontoon 41, a rotation is connected in pivot 42 of pontoon 41 upper end, four install between two pontoon 41 and the impeller 43 of being connected with pivot 42, a drive pivot 42 pivoted driving motor 44, all oxygenation waterwheel 4's rotation direction forms the closed loop, a slide opening 45 has all been seted up to the pontoon 41 at each oxygenation waterwheel 4 both ends downwards, each slide opening 45 equal sliding connection has a gag lever post 5 that inserts breed pond 1 bottom downwards, when making the water level change, oxygenation waterwheel 4 can reciprocate relative gag lever post 5 thereupon.

The working principle is as follows: during cultivation, prawns are cultivated in the cultivation pond 1, filter-feeding fishes such as tilapia, bighead carps and the like are cultivated in the cultivation isolation net 2, shrimp feed is fed to the shrimps at the edge of the cultivation pond 1, the shrimps can feed the shrimp feed at the edge of the pond, the polyculture fishes cannot rush to eat with the shrimps in the cultivation isolation net 2, the four oxygen-enriched water carts 4 rotate to enable pond water to flow in the same direction to generate vortexes, residual bait excrement generated by the shrimps is gradually concentrated into the cultivation isolation net 2 to be swallowed and filtered by the polyculture fishes, the final small amount of residual bait excrement is concentrated into the sewage collection funnel 3, and the residual bait excrement in the sewage collection funnel 3 is periodically pumped out by the water suction pump 33.
