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-mu ginseng pond of Hengshengyuan Seedling and Breeding Base, good results have been achieved through the following work:

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

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

[0029] 3. Nursery plants mostly use the dry-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 larval stage of the first ear, and 20,000 to 30,000 cells per milliliter in the larval stage of the middle ear. The ear ...

Abstract

The invention relates to a stichopus japonicus artificial breeding technology and relates to the field of trepang breeding. At present, researches and studies on artificial trepang breeding are few in China and even all over the world and systematized data on the artificial seedling technology are lacked. According to the stichopus japonicus artificial breeding technology, problems worth notification of all procedures are introduced in a systematized mode in the aspects of seedling facilities, water quality conditions, algae sort selection, bait cultivation and the like. Especially, caught and selected parent trepang should be scatheless trepang with the length of more than 20cm, the weight of more than 250g and the gonad index of more than 10%; larvas are bred, a shade-drying running water stimulation method is usually adopted in a breeding plant for inducing spawning, the cast bait is mainly cultivated algae includes chaetoceros mulleri, phaeodactylum, nitzschia closterium and the like. All procedures of spawning, incubation and larva breeding are well executed by controlling the cultivation density and the good effect is achieved.

Description

technical field [0001] The invention relates to the field of Apostichopus japonicus seedling raising, and specifically introduces the artificial seedling raising of Apostichopus japonicus from the aspects of seedling raising facilities and water quality, algae species selection and bait, collection, catching and breeding of parent ginseng, spawning and hatching, seedling picking, juvenile ginseng cultivation and the like. measure. Background technique [0002] Due to the high nutritional and medicinal value of sea cucumbers, the consumption demand of sea cucumbers has been rising in recent years, and sea cucumber seedlings have been paid more and more attention. System information is lacking. SUMMARY OF THE INVENTION [0003] 1. Breeding facilities and water quality conditions [0004] 1. The nursery facilities should be complete and complete. It mainly includes sedimentation and filtration facilities, oxygenation facilities, nursery rooms and bait rooms. The nursery w...
