Description
Technical Field
The utility model relates to a detection apparatus for northeast area is iced down and is put in big whitebait embryonated egg survival rate belongs to detection device technical field.
Background
The protosalanx hyalocranius is used as a small-sized economic fish of an annual age, and the parents die after reproduction. At present, the method is widely transplanted to lakes and reservoirs in northeast, forms a certain yield and is one of the main economic fish species of many lakes and reservoirs, such as the Sinkiang lake and the interlinked lake. In northeast region, breeding groups of the big whitebait are bred from 12 months per year to 1 month per year, egg laying breeding is carried out under ice to maintain the continuation of the groups, in order to improve the yield of the big whitebait, the breeding groups are harvested in winter, artificial insemination is carried out, fertilized eggs are put into lakes and reservoirs to supplement the quantity of the big whitebait, and further the yield is promoted to be increased, the egg diameter of the fertilized eggs of the big whitebait is about 1cm, and the fertilized eggs are beige. An effective detection device and method have not been obtained in the aspect of statistics of the success rate of fertilized egg laying in artificial propagation.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem that mentions in the above-mentioned background art, provide a northeast area under ice and throw detection device who enlargies whitebait embryonated egg survival rate.
The utility model provides a detection apparatus for throw enlarged whitebait embryonated egg survival rate under northeast, including bracing piece, couple, rope and detection basin, the bracing piece supports the opening part at the ice sheet, it has the couple to hang on the rope, it hangs on the bracing piece through rope and couple to detect the basin, be equipped with the bottom material in the detection basin.
Preferably, the detection basin is 15cm high.
Preferably, the thickness of the substrate is 10 cm.
Preferably, the detection basin is a plastic open basin.
Northeast area under ice put in detection device of big whitebait embryonated egg survival rate's beneficial effect do: the device is simple in manufacturing method and easy in material obtaining, and the method and the device are suitable for detecting the survival rate of the fertilized eggs of the large whitebait thrown manually in the northeast under the ice, and provide a scientific research basis for evaluating the effect of the large whitebait thrown manually.
Drawings
The accompanying drawings, which are incorporated in and constitute a part of this application, are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification.
In the drawings:
fig. 1 is a schematic structural view of a device for detecting the survival rate of fertilized eggs of an iced amplified whitebait in northeast of the present invention;
wherein, the detection device comprises 1-a support rod, 2-a hook, 3-a rope, 4-a detection basin, 5-an ice layer, 6-a substrate and 7-water.
Detailed Description
The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings:
the first embodiment is as follows: the present embodiment is explained with reference to fig. 1. This embodiment the northeast area throw detection device of enlarged whitebait embryonated egg survival rate under ice, including bracing piece 1, couple 2, rope 3 and detection basin 4, bracing piece 1 supports the opening part at ice sheet 5, it has couple 2 to hang on the rope 3, it hangs on bracing piece 1 through rope 3 and couple 2 to detect basin 4, it is equipped with substrate 6 in the detection basin 4.
The height of the detection basin 4 is 15 cm. The diameter of the bottom of the detection basin 4 is 30 cm. The thickness of the substrate 6 is 10 cm. The detection basin 4 is a plastic open basin.
Northeast area under ice put in big whitebait embryonated egg survival rate's detection method:
1. in 12 months in winter, the big whitebait breeding groups are collected and caught through the hanging net, and the big whitebait is quickly transported to an incubation farm by a water tank so as to ensure that the big whitebait suffers small temperature difference change after leaving water.
2. Carefully picking up the big whitebait, adopting wet fertilization, extruding the roe of the female fish with the ovary roe in a free state into a small basin filled with clear water, rapidly extruding the semen of the male fish, slightly stirring, washing for 2 times, and then putting into an incubation plane groove.
3. Before fish eggs are put in (about 7 days after wet fertilization), the development conditions of the fertilized eggs are sampled and detected under a microscope, and the hatchability before the fish eggs are put in is counted and recorded as the initial hatchability.
4. An incubation detection device was made as shown in fig. 1.
5. Before the roes are put in, a part of the bottom material 6 at the putting part is dug out by a mud sampler and put into the test basin 4, wherein the thickness of the bottom material 6 is about 10cm, so as to ensure that the roes sampled and detected and the batched roes put in have the same bottom material 6 incubation environment.
6. Picking up 300 live fertilized eggs under a microscope, placing the fertilized eggs above the paved substrate 6, placing a detection device in water 7, fishing out the device after 2 months, checking the number of the residual eggs in the pot, and recording the current hatchability as a sampling hatchability (remark: a plurality of detection devices can be manufactured at the same time, and the detection can be carried out in different putting areas).
7. The hatching rate of the big salangid is equal to the number of the big salangid put in, the first hatching rate and the sampling hatching rate.
The above-mentioned embodiments further explain the objects, technical solutions and advantages of the present invention in detail. It should be understood that the above description is only exemplary of the present invention, and is not intended to limit the present invention, and that any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention may be made without departing from the scope of the present invention.
