Embodiment 1

[0019] A method for cultivating tropical pink wart sea cucumber seedlings in a factory, comprising the following steps:

[0020] A. Collection and transportation method of parent ginseng: In August of each year, collect wild sea cucumbers with pink warts, and collect 130 parents of sea cucumbers with a body length of 6-8 cm. , and then the pure oxygen is transported to the breeding base as the artificially bred sea cucumber parent;

[0021] B. Methods of induction and fertilization: The individual of pink wart sea cucumber is small, and it takes multiple and successive inductions to obtain a sufficient number of eggs. Each time, the method of induction of labor in the shade is used to induce labor, and after 1 time of induction, it is necessary to resume breeding at an interval of 2 days and then induce labor again. After being stimulated by dryness in the shade, sperm are generally discharged in advance, and the discharged eggs are distributed in piles at the bottom of the w...

Embodiment 2

[0024] A method for cultivating tropical pink wart sea cucumber seedlings in a factory, comprising the following steps:

[0025] A. Collection and transportation method of parent ginseng: In August every year, wild pink wart sea cucumbers are collected, and a total of 135 pink wart sea cucumbers with a body length of 6-8 cm are collected and raised in clean sea water for 1 day. The pure oxygen in the live water is transported to the breeding base as the artificially bred sea cucumber parent;

[0026] B. Methods of induction and fertilization: The individual of pink wart sea cucumber is small, and it takes multiple and successive inductions to obtain a sufficient number of eggs. Each time, the method of induction of labor in the shade is used to induce labor, and after 1 time of induction, it is necessary to resume breeding at an interval of 2 days and then induce labor again. After being stimulated by dryness in the shade, sperm are generally discharged in advance, and the di...

Embodiment 3

[0029] A method for cultivating tropical pink wart sea cucumber seedlings in a factory, comprising the following steps:

[0030] A. Collection and transportation method of parent ginseng: in July every year, collect wild pink wart sea cucumbers, and collect 120 pink wart sea cucumbers with a body length of 6-8 cm. The pure oxygen in the live water is transported to the breeding base as the artificially bred sea cucumber parent;

[0031] B. Methods of induction and fertilization: The individual of pink wart sea cucumber is small, and it takes multiple and successive inductions to obtain a sufficient number of eggs. Each time, the method of induction of labor in the shade is used to induce labor, and after 1 time of induction, it is necessary to resume breeding at an interval of 2 days and then induce labor again. After being stimulated by dryness in the shade, sperm are generally discharged in advance, and the discharged eggs are distributed in piles at the bottom of the water...

Abstract

The invention discloses a method for cultivating tropical pink wart sea cucumber seedlings in a factory. Place the fertilized eggs of sea cucumber pink warts in clean sea water, adjust the density of fertilized eggs in the cultivation water to 0.03-0.10 / mL, and set the air cell density in the cultivation water to be 0.4-1.2 square meters / unit. After fertilization, the first 3 day, adjust the inflation strength of the air chamber to the bubble moving speed of 10-25cm / s on the water surface, and do not feed the bait; start feeding the bait on the 3rd day after fertilization. The inflatable strength of the chamber was adjusted to the bubble moving speed of 3-12cm / s on the water surface; after 10 days of fertilization, the water was changed frequently, and bait was fed until the seedlings were cultivated. The present invention utilizes the reproductive characteristic that the sea cucumber is not affected by the regularity of the moon phase, and adopts the method of multiple and step-by-step induction of labor to obtain a sufficient number of fertilized eggs, and solves the problems of small size and low egg production of the sea cucumber. The method of inducing labor can also improve the utilization efficiency of the parent and reduce the catch of the parent.

Description

Technical field: [0001] The invention belongs to the field of aquaculture, and in particular relates to a method for cultivating tropical pink wart sea cucumber seedlings in a factory. Background technique: [0002] Sea cucumbers (Holothuroidea) are a large group of echinoderms that mainly live in marine benthic life. Pink warty sea cucumber (Cercodemas anceps) is small in size and widely distributed in tropical / subtropical waters with coral reefs. It provides an important foundation. At the same time, the pink wart sea cucumber has bright body color, red and yellow, strong stress tolerance, and great seawater ornamental value, so the development and utilization of its biological resources is of great significance. [0003] However, it is still unclear how sea cucumbers reproduce and develop, and how their larvae are cultivated. The technical field of artificial large-scale breeding of sea cucumbers is still blank, which limits the development and utilization of biological ...
