Embodiment Construction
[0018] It is easy to understand that, according to the technical solution of the present invention, those skilled in the art can propose multiple structural modes and implementation modes that can be replaced without changing the essence and spirit of the present invention. Therefore, the following specific embodiments are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or limitation on the technical solution of the present invention.
[0019] A method for cultivating buried type shellfish larvae, comprising the following steps:
[0020] S01. After the shellfish develops to D-shaped larvae, wash them into the breeding basket. There is no need to add substrate in the breeding basket. The density of the ponds in the breeding basket is 10ind / ml, and the inner surface of the breeding basket is adhered to 300-mesh silk screen;
[0021] S02. Put the breeding basket ...

Abstract
The invention discloses a method for cultivating burying habitat type shellfish larvae. The method comprises the following steps of after shellfish grows to D-shaped larvae, washing young shellfishesinto a cultivation basket, not adding a substrate into the cultivation basket, ensuring that the pond distribution density in the cultivation basket is 10ind/ml, and adhering a 300-mesh bolting silk net to the inner surface of the cultivation basket; putting the cultivation basket into a cultivation water body for cultivation, feeding bait organisms into the cultivation basket at regular time, andmaintaining the concentration of the bait organisms at 5*10<5>ind/ml; introducing oxygen into the cultivation water body to keep the cultivation water body rich in oxygen; and performing regular young shellfish washing and water changing. Compared with the prior art, the method has the following advantages that 1, the cultivation basket is arranged in the cultivation water body, the cultivation environment is improved, and the young shellfish growth speed and survival rate are increased; 2, the substrate does not need to be added, seawater permeates through the 300-mesh bolting-silk net, andthe influence of zooplankton on young shellfishes is reduced; and 3, the young shellfishes are basically not damaged by washing the young shellfishes and changing water, and the labor cost is greatlyreduced.
Description
technical field [0001] The invention relates to the technical field of seawater shellfish larva cultivation, in particular to a method for cultivating buried shellfish larvae. Background technique [0002] Buried shellfish refers to sandy muddy or muddy sandy bivalves and gastropods that crawl or are buried in the intertidal zone, low tide zone and subtidal zone within 20 meters. The cultivation of buried shellfish has a long history in my country. The vast majority of buried shellfish cultured in my country are bivalves, mainly including: mud clams, hair clams, clams, clams, clams, clams, clams, clams, clams, clams, clams, Philippine clams , variegated clams, Xishi tongue, Kushijiang clams, Rainbow Mingying clams, etc. There are only a few species of gastropods, such as mud snails, red snails, and salamander snails. In recent years, the cultivation of buried shellfish has developed rapidly, the cultivation area is constantly expanding, the cultivation species are graduall...
