Technical Field

The invention relates to the technical field of big whitebait culture and propagation, in particular to a fertilized egg transplanting and putting facility for improving the hatchability of big whitebait.

Background

The Protosalanx hyalocerinus is the largest individual fish in the family of whitebait and the genus of whitebait; the large whitebait is a small economic fish, the protein content is high, the fat content is low, the protein content in the large whitebait is 80.7%, and the fat content is only 5.6%, so the large whitebait has high nutritional value, is an ideal tonic, can be eaten integrally, tastes delicious, is convenient to eat, can export and earn foreign exchange, can enrich the domestic aquatic product market, and is an rare high-quality fish, so the large whitebait is favored by farmers and consumers.

In the prior art, during the breeding and propagation process of the big whitebait, the germ cells of the big whitebait need to be transplanted and thrown, and the germ cells in the earstone appearing period and the larval fish in the internal and external mixed nutrition period can be normally hatched and survived under the condition that the water temperature drops suddenly by 6-8.5 ℃, so the two stages can be thrown; and devices for administering the fertilized egg, such as: in the publication of CN202714073U, the whole net-shaped oosperm transplanting and throwing netting device of big whitebait can be used, which is composed of net cage and netting, and the oosperm is put on the netting device and thrown into water, and the hatching condition can be checked regularly.

However, the above-described structure generally suffers from the following disadvantages: firstly, the fertilized eggs are easy to accumulate when placed in the netting gear, and particularly sometimes the netting gear needs to be pulled out to check the incubation condition of the fertilized eggs, so that the accumulation of the fertilized eggs is easy to cause and is unfavorable for subsequent incubation; secondly, during incubation, a large amount of oxygen is needed in water, and the existing equipment only arranges simple oxygen increasing equipment in the pond, so that the arrangement position of the oxygen increasing equipment is poor, the water body can be greatly disturbed, and fertilized eggs can be accumulated; thirdly, after the fertilized eggs are incubated into fry, the prior art mostly waits for the fry to naturally swim out of an incubation area, and if the number of the fry is large, the fry is accumulated in the incubation area, and the subsequent incubation of the fry is not facilitated; in addition, in the process of hatching the fertilized eggs, the putting device needs to be pulled out periodically to check the hatching condition, but the process can only see the condition of the pulled fertilized eggs, and the hatched fries have swim out of the hatching area, so that the hatching effect cannot be directly observed through the hatching condition of the fries.

Disclosure of Invention

Aiming at the defects in the prior art, the invention provides a fertilized egg transplanting and throwing facility for improving the hatchability of the big whitebait.
