Embodiment Construction

[0047] see figure 1 , figure 2 and image 3 , the concrete method of single oyster seed breeding of the present invention is as follows:

[0048] (1) Obtaining sperm eggs

[0049]Sperm and eggs are mainly obtained by the method of induced discharge: using the methods of drying in the shade, running water, warming or reducing salinity to induce mature gonad broodstock to discharge a large number of sperm and eggs. These induction methods can be used alone or in combination. Generally, dry the shellfish in the shade for 6-8 hours, and then put them into seawater with a temperature of 3-5°C after running water for 1-1.5 hours; after drying in the shade, directly stimulate them with seawater with a temperature of 3-5°C for 1-1.5 hours. You can also dry the shellfish in the shade for 10-12 hours, and then put them into seawater for discharge. The advantage of the induced discharge method is that it does not kill the brood shells, and the eggs mature better, but there are too ...

Abstract

The invention provides a method for culturing monomeric oyster seeds and a seed collector. The problems such as poor seed fixation effect, difficult substrate removal and the like in the prior art can be solved. By using a plastic corrugated plate as the fixation substrate of the monomeric oyster seeds in the invention, the problems such as unsatisfactory seed collection effect, difficult substrate removal, easy breakage of the oyster seeds, mutual conglomeration and attachment of oysters and the like in the prior art are solved.

Description

technical field [0001] The invention relates to marine product cultivation, in particular to a method for cultivating individual oyster seedlings and a seedling picking device. Background technique [0002] Individual oysters have many advantages such as fast growth, beautiful shell shape, easy breeding, processing and eating, so there has been a great demand in markets such as Europe and Japan, and they have extremely high economic value and social benefits. Oyster farming has broad prospects for development. Generally, there are three main methods for cultivating individual oysters in the traditional way: one is drug induction with epinephrine and noradrenaline; Compared with these three methods, the first drug induction method is not suitable for large-scale production, and the drug is easy to pollute the environment; the second particle immobilization method is easy to sink to the bottom after the oyster seedlings are fixed, resulting in excessive local density, which i...
