Problems solved by technology

[0002] Due to the high nutritional and medicinal value of sea cucumbers, the consumption demand of sea cucumbers has been increasing in recent years, and the cultivation of sea cucumbers has been paid more and more attention. However, at present, there are few research reports on artificial cultivation of sea cucumbers at home and abroad. Lack of system information

Embodiment Construction

[0026] In the 10-acre ginseng pond of Hengshengyuan seedling breeding and breeding base, good results have been achieved through the following work:

[0027] 1. Newly build sedimentation and filtration facilities, oxygenation facilities, nursery room and bait room. The water for seedlings is precipitated by the secondary filtration system, and then filtered out through the 300-mesh silk screen at the inlet of the pool;

[0028] 2. For pro-ginseng harvesting, individuals with a body length of more than 20 cm, a weight of more than 250 grams, a gonad index of more than 10%, and no damage are selected as pro-ginseng, and the stocking density is preferably 15 to 30 per cubic meter;

[0029] 3. Nursery plants mostly use the dry running water stimulation method to induce spawning. When larvae are cultivated, the daily feeding amount of algae is 15,000 cells per milliliter in the early ear larvae stage, and 20,000 to 30,000 cells per milliliter in the middle ear larvae stage. Ear lar...

Abstract

The invention relates to an artificial breeding method for Stichopus japonicus, belonging to the field of sea cucumber breeding. The research reports on the artificial breeding of the sea cucumber at home and abroad are very few at present and the artificial breeding technique lacks for systematic information. The invention systematically introduces notable problems of all links from the aspects of breeding facilities, water quality conditions, algae seed selection, bait cultivation and the like. Especially for the fishing of parent sea cucumbers, undamaged individuals with body length being above 20cm, body weight being above 250g and gonad indexes being above 10 percent are required to be selected as the parent sea cucumbers; and for larva breeding, breeding plants mostly adopt a shade-drying running water stimulation method to induce spawning, and the fed baits are mainly cultivated algae which comprise Chaetoceros muelleri, Phaeodactylum tricomutum, Nitzschia closterium Minutissima and the like. By controlling breeding density and well doing all links such as spawning, hatching and larva culture, a good effect is achieved.

Description

technical field [0001] The present invention relates to the field of raising sea cucumber seedlings, and specifically introduces specific measures for artificial seedling raising of sea cucumbers from the aspects of seedling raising facilities and water quality, selection of algae species and bait, harvesting and storage of parent ginseng, egg hatching, seedling picking, juvenile ginseng cultivation, etc. . Background technique [0002] Due to the high nutritional and medicinal value of sea cucumbers, the consumption demand of sea cucumbers has been increasing in recent years, and the cultivation of sea cucumbers has been paid more and more attention. However, at present, there are few research reports on artificial cultivation of sea cucumbers at home and abroad. Lack of system information. Contents of the invention [0003] 1. Nursery facilities and water quality conditions [0004] 1. Seedling raising facilities should be complete and complete. It mainly includes sed...
