Method for distributing perinereis aibuhitensis grube seedlings on large-area soil pit

Abstract

The invention provides a method for distributing perinereis aibuhitensis grube seedlings on a large-area soil pit, and belongs to the technical field of clam worm seedling breeding. The method includes the steps of soil pit preparation, seedling distribution, early management, intermediate management and later management. By means of the method, three-setiger nectochaeta of perinereis aibuhitensis grube are directly distributed on the soil pit. Compared with the method that seedling breeding is carried out in an indoor cement pit in the prior art, a lot of labor and materials are saved, meanwhile, the seedling intermediate collecting process is reduced, damage and death of the seedlings are avoided, and large-scale artificial breeding of the perinereis aibuhitensis grube is promoted.

Description

Technical field [0001] The invention belongs to the technical field of sand silkworm seedling cultivation, and specifically relates to a method for distributing seedlings in large-area soil ponds with double-toothed sand silkworms. Background technique [0002] At present, the method of raising seedlings of the double-toothed sandworm is mainly carried out in indoor cement ponds. After hatching, the fertilized eggs of bidentate sandworms become 3 rigid larvae. In addition to adding a large number of microalgae, such as Isochrysis and mixed algae (Chaetoceros + Platymona + Microchlorococcus), you also need to add fine sand. When the larvae of the larvae develop to the 11th knot, collect the larvae of the 11th knot and move it to the outdoor earth pond. During the entire cultivation process, it needs to occupy a large amount of water. The microalgae fed during the cultivation process needs to be cultivated by a dedicated person. The cultivation process requires a lot of manpower ...

AI Technical Summary

Problems solved by technology

When the clamworm larvae develop to 11 knots, collect the clamworm 11 knot larvae and move them to the outdoor earthen pond. During the whole cultivation process, a large amount of water body needs to be occupied, and the microalgae fed during the cultivation process need to be cultivated by a special person. Therefore, The cultivation process requires a lot of manpower and material resources, which is not conducive to large-scale cultivation of nereist larvae seedlings. At the same time, the seedlings will be damaged and killed during the collection and transfer of 11-gang nereist larvae, which greatly limits the ability of the double-toothed nereis.
