Compared with prior art, the utility model has the advantage of: a kind of high density aquatic products of the utility model larya culturing device, its casing is primarily of rectangle half-light district and semicircular transparent area composition, half-light district is made up of half-light culture zone and water outlet race way, come with at least one deck screening filtering net longitudinal subdivision in half-light culture zone and water outlet race way, the bottom of screening filtering net is connected with the upper edge one of transparent area by the base plate of water outlet race way, casing is respectively arranged with water inlet pipe, breather pipe and outlet pipe, outlet pipe is positioned on the outer wall casing of water outlet race way, time by day, open the oxygen that air pump keeps sufficient, outlet valve is opened after opening water pump, device starts to inject fresh seawater by water inlet pipe, screening filtering net starts to work, keep height of water level and filtration, when water level is too high, water can be discharged from outlet pipe.In the process of the cultivation young, enhance the circulation of breeding water body, the wall of the upper part of device keeps dark condition, be conducive to living body bait and the biological young and move to darker printing opacity waters, avoid excessive surface crowded, thus decrease the M & M of the young, improve growth rate and survival rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high density aquatic products of the utility model larya culturing device.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
Specific embodiment
A kind of high density aquatic products larya culturing device, as shown in Figure 1, comprise rectangular box 1, casing 1 is that semicircular transparent area 3 forms primarily of rectangular half-light district 2, upper strata and lower floor along the longitudinal cross-section of casing 1 length direction, half-light district 2 is made up of half-light culture zone 4 and water outlet race way 5, come with at least one deck screening filtering net 6 longitudinal subdivision in half-light culture zone 3 and water outlet race way 5, the bottom of screening filtering net 6 is connected with the upper edge one of transparent area 3 by the base plate 7 of water outlet race way 5, casing 1 is respectively arranged with water inlet pipe 8, breather pipe 9 and outlet pipe 10, outlet pipe 10 is positioned on the outer wall of water outlet race way 5.
In this particular embodiment, as shown in Figure 1, the outer wall in half-light district 2 adopts opaque grey black PC plate to surround, and transparent area 3 outer wall adopts transparent acrylic board to surround.The delivery port of water inlet pipe 8 close to the position at water surface center and opening direction down, the diameter of water inlet pipe 8 is 10-50 mm, and inflow is 0.1-1 L/s.The gas outlet of breather pipe 9 is positioned at the below of the delivery port of water inlet pipe 8, and gas outlet is positioned at below delivery port, and in energy increase system, the mobility of water, improves the abundant circulation of breeding water body; The internal diameter of breather pipe 8 is 4-10 mm, external diameter 7-14 mm, and aeration quantity scope is 0.5-36 L/h.Base plate 7 is obliquely installed in 45 degree, the interface between half-light district 2 and transparent area 3 and form dark fallback area 11 between base plate 7.
In this particular embodiment, the volume size scope of casing 1 is 27-102 L, the length of casing 1: wide: height=480mm:240mm:355mm, longitudinal direction half diameter of a circle of transparent area 3 is the length of 450mm, water outlet race way 4: wide: height=240mm:165mm:(120-180) mm.
Experimental test
Aeration quantity magnitude range is tested, by air pump to breather pipe 9 oxygenation of device, the internal diameter of breather pipe 9 is 4-10 mm, external diameter 7-14 mm, and adjustable ventilation scope is 0.5-36 L/h, under strong aerobic condition, per second about have 11 ± 1 diameters to be approximately the bubble of 24 ± 3 mm, and water velocity is equivalent to 420 ± 35 mm/s, under weak aerobic condition, 21 ± 3 diameters are had each second to be the bubble of 11 ± 2 mm, about 370 ± 32 mm/s of water velocity.
The mensuration of inflow scope, by water pump to water inlet pipe 8 water filling of device, the size of inflow can pass through Valve controlling, and the diameter of water inlet pipe is adjustable, scope from 10-50 mm not etc., inflow 0.1-1 L/s.
The measure of merit that breather pipe 9 and water inlet pipe 8 act on simultaneously, when air pump and water pump being opened simultaneously, the water velocity of measurement mechanism is adjustable in 100-1000 mm/s scope.This device of sufficient proof, at the ingehious design of breather pipe 9 with the position of water inlet pipe 8, considerably increases the circulation of water body.
The selection of screening filtering net 6 mesh, according to the number of the young to the particle size of solid particulate matter in the adaptive capacity of water body and breeding water body and amount, and the speed conditions of current, preliminary use by day 30 or 35 object filter screens, use 60 object filter screens at night, the selection for different biological young meshes should be differentiated.
In system, aquatic products young distributing homogeneity measures, i.e. the mensuration of cycle water state, by opening air pump and water pump, according to the speed of current in water cycle process and the adaptation distribution situation of the young, judges the good of cycle water state.In order to further checking, test with larvae of Penaeus vannamei (total length 0.6-0.8 cm), result is as table 1:
Table 1 cycle water state estimating information slip
Note :+indicate distribution, ++ represent dense distribution, one represents distribution-free.
Above-described embodiment further illustrates of the present utility model, but protection domain of the present utility model is as the criterion with claims.
