Abstract
The utility model discloses a device for collecting blue-green algae by culturing fishes, which comprises a unit net cage for stocking algae-eaters, and is characterized in that the bottom of the net cage is provided with an algae dung collector. In the utility model, the bottom of the fish culture net cage is provided with the algae dung collector, blue-green algae in a lake is ingested through the algae-eaters and then is converted into the algae dung through digestion of the fishes, and the algae dung is collected through the algae dung collector, so that the quantity of the blue-green algae in the lake can be controlled biologically, the content of N and P in the water body can be effectively reduced, the water quality is reduced, the water use safety is improved, and circulating economic support is obtained.
Description
Technical field
The utility model relates to lake water quality abatement equipment, specifically a kind of device that purifies water by cultured fishes collection blue-green algae.
Background technology
The purpose of tradition fish culture in net pen is to utilize the biological and water body space production fish of natural bait, and technical measures such as its laying mode, kind selection, breeding density are not to administer at lake blue algae.With cultured fishes is that purpose tradition net cage is not collected the fish excrement, causes the pollution of fish excrement to water body.
Fish control algae is meant puts food algae fish in a suitable place to breed in water body, ingest algae to reach the purpose of control algae by fish, but its root problem is, fish ingest, and N, P and algae excrement do not leave the ecosystem substantially behind the algae, promptly fundamentally do not solve the water quality eutrophication problem.
The utility model content
The utility model is in order to solve the weak point that prior art exists, provide a kind of cultured fishes to collect the blue-green algae device, control blue-green algae with the fish blue-green algae that ingests, simultaneously fish algae excrement is effectively collected, with the once more eutrophication of effective reduction N, P in water body, in restoration of the ecosystem, can directly obtain economic benefit.
The utility model technical solution problem adopts following scheme:
The blue-green algae device is collected in a kind of cultured fishes, comprises the unit net cage of putting food algae fish in a suitable place to breed, and its design feature is: be provided with algae excrement gatherer in described net cage bottom.
The blue-green algae device is collected in a kind of cultured fishes of the utility model, and its design feature also is:
Described algae excrement gatherer is to be made by close eye net sheet, and its bottom is provided with able to turn on or off collection algae excrement mouth.
Described algae excrement gatherer is a funnel type.
Described close eye net sheet mesh is 0.8-1.2mm, and described algae excrement gatherer height is 200cm～300cm; Described algae excrement gatherer and net cage removably connect.
Described blue algae collecting device bottom also hangs with a weight.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is provided with algae excrement gatherer in the fish culture cage bottom, blue-green algae in the lake ingests by food algae fish, change into the algae excrement, by algae excrement gatherer it collected again by fish digestion again, not only can be by the quantity of BIOLOGICAL CONTROL lake blue algae, effectively reduce N, P content in the water body, improve water quality, improve water safety and can obtain circulation economically and support.
2, algae excrement gatherer of the present utility model is avoided the secondary pollution of fish algae excrement to water body, the algae excrement of collection can be processed into bio-feritlizer or directly as the plantation fertilizer so that resource is effectively utilized.
3, the utility model can directly obtain economic benefit on one's body from food algae fish, to keep rerunning of restoration of the ecosystem engineering and facility in restoration of the ecosystem and water correction.
Description of drawings
Fig. 1 is the utility model structural representation.
Number in the figure: 1 net cage, 2 fish excrement gatherers, 3 weights.
By the following examples technical solutions of the utility model are described further.
The specific embodiment
Referring to Fig. 1, the blue-green algae device is collected in cultured fishes, comprises the unit net cage 1 of putting food algae fish in a suitable place to breed, and net cage 1 bottom is provided with funnel type algae excrement gatherer 2.Algae excrement gatherer is to be made by close eye net sheet, and mesh is 0.8-1.2mm, highly is 200cm～300cm, and its bottom is provided with able to turn on or off collection algae excrement mouth.Algae excrement gatherer and net cage removably connect.In order to strut the blue algae collecting device, hang with a weight 3 in its bottom.
