Description
Technical field
The present invention relates to a kind of aquaculture system, particularly a kind of large nacre intermediate rearing cultivating system.
Background technology
Large nacre is commonly called as white butterfly shell, is national second class protection aquatic animal, is maximum marine products pearl shell.Large nacre can produce that gloss is very strong, the large pearl of beautiful appearance, has very high economic worth and scientific research value.But, large nacre is very harsh to existence, growing environment, very easily by the impact of the changes such as water temperature, seawer quality, salinity, dissolved oxygen, intensity of illumination, after the large batch of phenomena of mortality appear in the natural waters cultivation of large nacre in 1985, nowadays large nacre natural waters cultivation is difficult to breakthrough 3 ~ 5cm.And at present large nacre is transferred to the indoor culture of manual control environment can become the Main way breaking through this bottleneck from natural waters cultivation.
Large nacre has very strong to ingest, digests and discharge capacity, propagate artificially under condition mainly with cultivate single-cell algae be bait, but owing to very strong to ingest, to digest and discharge capacity, cause needing to change water in a large number, frequently throw algae in traditional indoor culture mode process, but change water process in a large number and not only stress reaction is caused to large nacre, and causing bait algae to run off in a large number, because this increasing the demand of bait algae, too increasing the input of labour intensity and breeding facility.
So traditional indoor culture pattern is difficult to meet the needs cultivating large gauge large nacre in indoor on a large scale.
Summary of the invention
A kind of good water quality, minimizing quantity of exchanged water, bait of can keeping for a long time is the object of the present invention is to provide to run off less and reduce the large nacre intermediate rearing cultivating system of labour intensity, the time of large nacre at indoor culture can be extended, a large amount of large gauge large nacre kind can be cultivated, thus solve the problem of large nacre in natural waters high mortality.
Object of the present invention is realized by following technical measures: a kind of large nacre intermediate rearing cultivating system, it is characterized in that: it comprises outer groove and is enclosed the inside groove drawn together by outer groove, concentrate successively according to water (flow) direction in described outer groove and be provided with through plate, water level plate, screen cloth and baffle plate, wherein, described through plate, water level plate and baffle plate are that vertical interval is arranged, the bottom of described through plate and the bottom surface of outer groove have space, described water level plate and baffle plate shutoff make to form filtration hydroecium therebetween in outer groove, described water level plate is lower than the cell wall of described outer groove, described screen cloth covers on the top of filtration hydroecium, and described screen cloth tilts towards baffle plate from water level plate, be provided with for trapped dirt and the blow-off pipe of discharging at the low side of screen cloth, the described outer groove region be between baffle plate and through plate is culture zone, the attaching device of attachment beneficial bacterium is provided with in described inside groove, the cell wall of inside groove is provided with the clear water output being communicated with culture zone, the water body of culture zone flows into filter in hydroecium and is extracted to inside groove again after screen filtration, after beneficial bacterium purified treatment, flow into culture zone from clear water output thus realize water circulation.
The present invention can self-purging breeding water body, make it to recycle, water quality can be made to maintain a good state for a long time, thus decrease and change waterside number, decrease the stress stimulation to large nacre, decrease the bait algae adjoint due to draining to run off, and then decrease the supply of bait, also correspondingly reduce labour intensity.
As a modification of the present invention, described inside groove is divided into tank and ringwise inner groove, described attaching device distributes along the annular chamber of inner groove, described clear water output is positioned on the cell wall of described inner groove, described tank communicates with filtration hydroecium, in described tank, be provided with water plug, the delivery port of water plug extends the top of inner groove.
As a kind of preferred embodiment of the present invention, described outer groove and inner groove are longitudinal bodies, described filtration hydroecium is in one end of outer groove, described outer groove is the initiating terminal of culture zone near the position of baffle plate, described outer groove is the end of culture zone near the position of through plate, the delivery port of described water plug is positioned at one end of inner groove, this end is the initiating terminal of inner groove, described clear water output is positioned at the initiating terminal of described culture zone and is positioned at the end of inner groove simultaneously, the water body flowed out from the delivery port of water plug flows through from the initiating terminal of inner groove the end that attaching device returns inner groove again.
As a further improvement on the present invention, the cross section of described outer groove annular chamber is U-shaped, and the two ends of described outer groove are rounded transitional.Outer groove is runway shape ringwise, and culture zone water body, with certain flow rate, contributes to strengthening the feed efficiency of large nacre, and makes water body not stay dead angle in flow process, and water body can complete exchange, ight soil can concentrate and be deposited in bottom to discharge.
The present invention can also do following improvement, and the bottom surface of described inner groove is higher than the bottom surface of outer groove, and the cell wall of described inner groove is higher than the cell wall of outer groove.Can make automatically to flow into the culture zone of outer groove from clear water output through cleaned water.
