Embodiment 1

[0026] Such as figure 1 Shown, the artificial breeding method of the sea chrysanthemum clam of the present embodiment comprises the following steps:

[0027] a. Collection of parents: On April 3, 2021, 30 2-3-year-old wild Jiehai chrysanthemum clams with good health and vitality were collected in the reef area with a water depth of 10 meters in the Luhuitou sea area of ​​Sanya (the shell length is greater than 10cm). After removing the attachments on the shell, it is temporarily raised in the Hainan Tropical Marine Biological Experiment Station of the South China Sea Institute of Oceanology, Chinese Academy of Sciences. The seawater temperature is 28-30°C, the salinity is 34ppt, and the pH is between 8.0-8.2. The combined methods were used to identify the parents, and the results showed that they were all clams.

[0028] b. Promoting ripening of parents: artificially promoting ripening in the form of micro-inflation + micro-flowing water, with a water flow of 20m 3 / day / cyl ...

Embodiment 2

[0036] The artificial breeding method of the sea chrysanthemum clam of the present embodiment comprises the following steps:

[0037] a. Collection of parents: On May 3, 2021, 40 healthy and undamaged wild Jiehai chrysanthemum clams of 2-3 years old were collected in the reef area with a water depth of 10 meters in Lingshui sea area (the shell lengths were all greater than 10cm). After removing the attachments on the shell, it is temporarily raised in the Hainan Tropical Marine Biological Experiment Station of the South China Sea Institute of Oceanology, Chinese Academy of Sciences. The seawater temperature is 28-30°C, the salinity is 34ppt, and the pH is between 8.0-8.2. The combined methods were used to identify the parents, and the results showed that they were all clams.

[0038] b. Promoting ripening of parents: artificially promoting ripening in the form of micro-inflation + micro-flowing water, with a water flow of 20m 3 / day / cyl (3000L / cyl), after a month of ripening,...

Abstract

The invention discloses an artificial breeding method of sea cauda. The method comprises the steps of parent collection and maturity promotion, spawning induction and incubation, larva cultivation, juvenile mollusk cultivation and the like. The method has the advantages and positive effects that a long-term unsuccessful rearing technology of the clam offspring seeds is broken through; a set of method suitable for artificial breeding of the sea cauda is established, a large number of sea cauda fries are bred, and the domestic blank is filled. The method disclosed by the invention has important practical significance on culture development, resource recovery and biological diversity maintenance of the sea cauda.

Description

Technical field: [0001] The invention belongs to the technical field of shellfish seed breeding in marine agriculture, and in particular relates to an artificial breeding method of sea chrysanthemum clams. Background technique: [0002] Sea chrysanthemum clams, commonly known as hamburger clams, are a type of tropical and subtropical marine coral reef benthic shellfish. The shell surface has well-developed radial ribs, and there are long and short spines of different shapes on the ribs. The shell surface of sea chrysanthemum clam is colorful, including pink, blood red, orange red, yellow, white, purple and so on. The bright colors and delicate and uneven spines make up the blooming chrysanthemums, which is why the sea chrysanthemum clam got its name. Therefore, it is not only an important class of reef-building and reef-protecting organisms, but also a water cluster animal that is widely popular in the market and loved by the public; it is also the main viewing object for d...
