Embodiment
Below in conjunction with accompanying drawing, silvery pomfret fertilized egg device for sorting of the present invention and using method thereof are described in further detail.
As shown in Figure 1, silvery pomfret fertilized egg device for sorting of the present invention, Glass fibre reinforced plastic tub 1, bolting silk net 8 and water pump 2, linked together by bolting silk net 8 between first sub-sieve circle 6 and the second sub-sieve circle 7, make the bolting silk net post under large a, end opening suitable for reading, in bolting silk net post, a gas stone 11 is set near current side, top; First sub-sieve circle 6 is fixed on above two parallel waddys 4 by static line 5; A water pump 2 is fixed bottom Glass fibre reinforced plastic tub 1; One end of water pipe 3 connects the mouth end that water pump 2 other end is fixed on Glass fibre reinforced plastic tub 1; The mouth end of Glass fibre reinforced plastic tub 1 arranges place 20 order and stops net 10, and the bottom of Glass fibre reinforced plastic tub 1 is provided with water discharging valve 9; Be conical bottom Glass fibre reinforced plastic tub, volume 900 liters, mouth end diameter 1.0 meters ~-1.2 meters; First sub-sieve loop diameter is 40 centimetres, and the second sub-sieve loop diameter is 20 centimetres, and vertical height is between the two 50 centimetres; The order number of bolting silk net is 1.4 millimeters, 12 order aperture; Pump head 2 meters; The water outlet end of water pipe is dipped in below the water surface, is 30 degree of angles with the water surface.
The using method of silvery pomfret fertilized egg device for sorting: fill fresh seawater in Glass fibre reinforced plastic tub 1, opens water pump 2, makes water body in Glass fibre reinforced plastic tub 1 be in slow circumvolve state always.Gas stone 11 is ventilated, then the fertilized egg of collection is put into bolting silk net post.After half an hour, unified for the fertilized egg in bolting silk net post collecting is moved in hatchery.Finally to stopping that the fertilized egg of being detained bottom online and Glass fibre reinforced plastic tub is removed.
2014 Mays 5 days, to June 20, carried out silvery pomfret fertilized egg percent test.
(1) determination of high-quality silvery pomfret fertilized egg
Silvery pomfret fertilized egg is buoyancy, heavy property and opaque ovum are dead ovum, on May 5th, 2014 obtains a collection of silvery pomfret fertilized egg, after rejecting dead ovum, fertilized egg is divided into 3 groups according to ovum footpath size, namely 1.5 millimeters, 1.5 millimeters ~ 1.4 millimeters and be less than 1.4 millimeters are greater than, often organize three to repeat, often repeat to select 100 fertilized eggs, test and carry out in 20L white bucket, test water temperature 18 degree, salinity 26.
Table 1 different disposal group fertilized egg nursery situation
| Ovum footpath size (millimeter) | Incubation rate (%) | Abnormal rate (%) | 3 age in days larvae survival rates |
| Be greater than 1.5 | 100±0.00 a | 8.12±1.24 a | 100 a |
| 1.5～1.4 | 95.33±2.15 a | 10.33±2.38 a | 100 a |
| Be less than 1.4 | 30.27±5.21 b | 70.58±9.11 b | 20.15±3.62 b |
Note: the different Superscript letters of same row indicates significant difference (P<0.05).
Table 1 shows each experimental group incubation rate, abnormal rate and 3 age in days larvae survival rate situations.As can be seen from Table 1, be greater than 1.5 millimeters of groups and organize hatchability of fertile eggs, abnormal rate and 3 age in days larvae survival rates all apparently higher than being less than 1.4 millimeters of groups with 1.5 millimeters ~ 1.4 millimeters.Can draw thus, the silvery pomfret fertilized egg that buoyancy, full grains, transparent and ovum footpath are more than or equal to 1.4 millimeters is high quality fertilized egg of scophthatmus.
(2) fertilized egg select and hatching, cultivating test
Get obtained part silvery pomfret fertilized egg to be selected by this device, the water discharging valve 9 of Glass fibre reinforced plastic tub 1 is closed, then in Glass fibre reinforced plastic tub 1, fill fresh seawater, open water pump 2, make water body in Glass fibre reinforced plastic tub 1 be in slow circumvolve state always, gas stone 11 is ventilated, again the fertilized egg of collection is put into bolting silk net post, because silvery pomfret fertilized egg is buoyant egg, the ovum sunk to the bottom mostly is dead ovum, directly sink to bottom Glass fibre reinforced plastic tub, drain by water discharging valve 9.The fertilized egg that buoyancy double egg footpath is less than 1.4 millimeters slowly to be drifted about out bolting silk net post by the impetus of air-flow in current in Glass fibre reinforced plastic tub 1 and gas stone, be trapped in and stop net 10 place, after half an hour, the ovum finally stayed in bolting silk net post mostly is the good fertilized egg of quality, after sub-sieve terminates, unified for the fertilized egg in bolting silk net post collecting is moved in hatchery, finally the seawater in Glass fibre reinforced plastic tub 1 is drained.
From the silvery pomfret fertilized egg that this device is picked out, random choose 900 carries out hatching test, is divided into three groups, often organizes 300.Test show that its average percentage hatch rate is 92.33%, and average abnormal rate is that 13.74%, 3 age in days prelarva average survivals reach 98.77%.
Silvery pomfret fertilized egg device for sorting of the present invention and using method thereof avoid the fertilized egg damage that hand picking may cause, and have greatly saved human cost; The effective separating, selecting of the present invention has gone out the measured fertilized egg of matter, avoids a large amount of dead ovum and is gathered in hatchery and affects water quality and seedling incubating rate, ensured final survival rate of seedling, improve the benefit of nursery.
Below the preferred embodiment of the invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
