Embodiment

[0009] Taking a japonicus nursery pond with an effective water body of 1000 cubic meters as an example, there are 50 cultivation ponds with a depth of 20 cubic meters and a depth of 1.1 meters. The specific breeding process includes: Breeding density: After breeding, the breeding density of microtia larvae is calculated based on the pool full of water, controlled at 0.2 / ml, the temperature of the pool water is controlled at 22-23°C, and 4 million larvae are placed in each breeding pool . After the pool is set up, a small amount of air is continuously inflated.

[0010] ①Water level and water quality control: When microtia larvae are bred in cloth ponds, only 50cm of water is added to the cultivation ponds. After the selection, according to the actual number of water bodies, 50ml of Bacillus subtilis was put into each cultivation pool. No more water was added thereafter. From the 4th day after the selection, 10cm of fresh seawater was added every day, and 2ppm of Bacillus su...

Abstract

The invention relates to a method for cultivating planktonic larvae of sea cucumber, which belongs to the technical field of seedling raising of sea cucumber; the technology includes the following steps: breeding density; water level and water quality control; dry bait; feeding of attachment base; The density of larvae is raised by using dry bait to cultivate larvae, which solves the problem of difficult transportation and storage of fresh bait or concentrated liquid bait; with the assistance of micro-ecological preparations, a new water quality control method is adopted, and the entire seedling raising period is only changed once after the attachment substrate is placed. Water greatly saves the cost of changing water during the sea cucumber seedlings, can effectively prevent and control diseases, saves the cost of bait cultivation, transportation, and storage, and greatly improves the efficiency of sea cucumber seedlings.

Description

technical field [0001] The invention relates to a method for cultivating sea cucumber planktonic larvae, belonging to the technical field of sea cucumber seedling cultivation. Background technique [0002] In recent years, with the development of my country's economy, sea cucumber, as a species with high nutritional value, has become more and more popular, and the industry of sea cucumber nursery and breeding has developed accordingly. At present, there are problems in the cultivation of sea cucumber seedlings such as the difficulty of transportation and storage of fresh bait or concentrated liquid bait; the problems of large water exchange, high cost of water, electricity and labor, and waste of resources. These problems have hindered the efficient development of sea cucumber seedling industry. Contents of the invention [0003] The purpose of the present invention is to adopt dry bait to cultivate larvae by controlling the reasonable density of planktonic larvae of sea ...
