Embodiment 1

[0027] A method for upside-down scattered domestication of Apostichopus japonicus parents, induction of labor and efficient cultivation of seedlings, the method comprises the following steps:

[0028] A. Tropical sea cucumber collection and transportation method: Collect wild tropical sea cucumber parents. Since sea cucumbers will eat a lot, the intestines of wild sea cucumbers will contain a lot of sediment, which is not resistant to transportation at this time, and needs to be temporarily raised in clean sea water 2 Days, after removing the sediment, it is transported to the breeding base.

[0029] B. Dispersed domestication method by hanging upside down: In the indoor cement pool, in order to create a dark environment to induce sea cucumbers to hide under the cement board, and to avoid the sea cucumbers getting together and clinging to each other to cause rotten skin, the cement board leans against the cement pool wall, The cement boards in the cement pool are placed in a c...

Abstract

The invention discloses a method for upside-down scattered domestication, induction of labor and efficient seedling cultivation of Apostichopus japonicus parents. The invention utilizes the living habits of the tropical sea cucumber, makes the tropical sea cucumber hang upside down and is dispersed in the cement pool for domestication, prevents the skin on the back of the parent from festering due to the mutual clinging due to the need to avoid light, and improves the utilization rate of the tropical sea cucumber parent. . Through reasonable breeding density, fully agitating the plankton water body automatically by air pump, adopting various methods to improve the efficiency of larvae's metamorphosis attachment, rationally feeding the bait without live algae to stabilize the water body, and discloses the cultivation method of tropical sea cucumber.

Description

Technical field: [0001] The invention belongs to the field of aquaculture, and particularly relates to a method for the scattered domestication, induction of labor and the efficient cultivation of seedlings of Apostichopus japonicus parents by hanging upside down. Background technique: [0002] Sea cucumber (Holothuroidea) is one of the eight treasures in the world and has important dietary value. my country is the most important consumer market. With the development of my country's economy, the demand for tropical sea cucumbers has increased rapidly. However, the growth rate of sea cucumbers is slow, the time to sexual maturity is long, and the replenishment cycle of new individuals of sea cucumber populations is long. Overfishing has destroyed sea cucumber population resources. About 100,000 tons of fresh wild sea cucumbers are caught every year. In the South my country Sea waters, after years of disorderly fishing, tropical sea cucumber resources have been depleted. In v...
