Rana spinosa eggmass collecting device and collecting method thereof

Abstract

The invention discloses a rana spinosa eggmass collecting device and a collecting method thereof, mainly comprising a spawning pond and a parental rana spinosa pond; the bottom of the spawning pond isconnected with a group of supports, each support is provided with an eggmass collecting device, one side of the eggmass collecting device clings to the wall of the spawning pond, and the distance of5 cm to 15 cm is preserved between one side of the eggmass collecting device adjacent to the parental rana spinosa and the parental rana spinosa; the distance of 5 cm to 15 cm is also preserved between every two eggmass collecting devices; and the upper surface of each eggmass collecting device is parallel with the water surface of the spawning pond. The invention has the beneficial effect that the rana spinosa eggmass can be directly delivered into hatchery equipments for hatching after collection by the eggmass collecting devices and conveying. The device and the method save both time and manpower and have high collecting efficiency as the step of separating eggs from attachments can be avoided; and the eggs can be protected well so as to realize long-distance transportation and bring benefits to production. The equipment is simple; the operation is convenient; and egg density is high and damage to eggs can be avoided so as to realize 100-percent survival rate of the eggs in transportation.

Description

technical field [0001] The invention relates to the field of egg mass collection, more specifically, it relates to a stone frog egg mass collection device and collection method. Background technique [0002] The scientific name of the stone frog is Rana Spinosa David, and the collection of egg masses during its breeding is one of the key technologies for domestication and breeding. The conventional method of collecting stone frog eggs is to separate the adhesive membrane outside the frog eggs from the pool wall or other attachments in the spawning pool of the parent frog with bare hands or with a scraping tool. Egg grains; put the egg mass into a container of water and transport it to the hatching tank for incubation. Because this method is time-consuming and labor-intensive, it is not only difficult to clean the same batch of frog eggs, but also damages the frog eggs due to scraping, affects embryonic development, and reduces the hatching emergence rate. Contents of the ...
