Problems solved by technology

The artificial propagation of Reichthys chinensis is quite special. The mature larvae must parasitize on the gills and fin rays of the fish, and survive and metamorphose into juvenile clams. Because most of the larvae cannot meet the intermediate host and die young, Therefore, relying on natural multiplication to carry tumor-backed mussel resources is very limited, and cannot meet the needs of the development of nucleated pearls.

Embodiment Construction

[0017] 1. Selection and cultivation of parent mussels

[0018] 1. Clam selection criteria

[0019] The clam species used for artificial reproduction is called the parent clam. As the saying goes, "good seedlings come from good seeds", the quality of the parent clam directly affects the offspring, which is the principle of genetic factors. There are many kinds of clams in our country. You should choose high-quality varieties with fast growth, large individuals, thick shells and hard shells as brood clams, so as to have breeding value. Brood clams should be young, generally about 4-6 years old, and the shells are intact. Both male and female clams have strong and plump bodies and undamaged gills.

[0020] 2. Cultivation of parent mussels

[0021] The brood mussels selected from the salvage of wild clams are hung and raised in the brood ponds, and the male and female are matched reasonably to increase the fertilization rate. The water surface for mussel breeding should not be ...

Abstract

An artificial reproduction method for Beiliuli clam includes such steps as choosing excellent parent clams, culturing them in pool in hanging mode, taking ova, putting the host fish in the water in a tub, attaching the glochidiums onto host fish, culturing the host fish in culture pool until the young clams is separated from the host fish, culturing the young clams in water surface in hanging mode, and culturing in square crate in shallow water.

Description

technical field [0001] The invention relates to an artificial production method of mussels, in particular to a method for artificial production of mussels. Background technique [0002] The freshwater pearls that are usually cultured in my country are generally non-nucleated pearls, and the production of nucleated pearls is not much. The raw material of nucleated pearls is mainly the shell of river mussels, because it is the same raw material as pearls, and the quality of nucleated pearls is good. Mussels usually used as nucleated clams are thick and hard shells, such as the back tumor, the three giant tumor, the multitumor, and the oval clam. These mussels are widely distributed in my country, and the output is low. Can not meet the market demand, rely on imports in the near future. Tumor clam, also known as iron clam, maple clam, hoofed clam, it is relatively large, oval in shape, very short in the front, long and flat in the back, very thick and hard shell, dark brown or ...
