Example Embodiment

[0037] Example 1

[0038] A method for artificial breeding of sea cucumber seedlings includes the following steps:

[0039] (1) 15 days before the peak spawning period of sea cucumbers, harvest sea cucumbers with a body weight of 300-400 g, well-developed gonads, normal body, no damage, and no abnormalities in natural seas as their relatives, and store them at Temporary breeding in the holding tank. There are hidden objects at the bottom of the holding tank. During the holding period, the water quality in the holding tank is as follows: seawater salinity 29-30‰, PH7.8-8.2, continuous trace aeration, dissolved oxygen Maintain above 5mg / l, water temperature 18-20℃;

[0040] During the temporary rearing period, feed once in the morning and evening. The daily feeding amount is 3-5% of the body weight of the parent ginseng. The feed for the parent ginseng is prepared from the following components: 45 parts of white fish meal, 25 parts of Salvia powder, sea 30 parts of mud, 8 parts of so...

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to an artificial breeding method of a stichopus japonicus fry. The artificial breeding method comprises the following steps: (1), selecting healthy and strong stichopus japonicus as stichopus japonicus parents, and temporarily farming the stichopus japonicus parents in a temporary farming pool; (2), inducing theparent stichopus japonicas to spawn and fertilize; (3), hatching fertilized eggs; (4), soaking, sterizing and thoroughly rinsing attachment substrates with an oxalic acid solution, putting into nursery ponds, and attaching natural baits containing benthic diatoms to the attachment substrates before fry addition; (5), hatching the fertilized eggs for 20-30 hours in a hatching pond, enabling the fertilized eggs to enter a planktonic larva stage, dividing planktonic larvae into the nursery ponds, and when doliolariae account for 15-20% of the total number of the larvae, adding the attachment substrates treated by the step (4). The artificial breeding method has the advantage of improving the fry quality and the fry breeding survival rate.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an artificial breeding method of japonicus seedlings. Background technique [0002] sea ​​cucumber ( Stichopus japonicus ) is a kind of sea cucumber, belonging to the sea cucumber class ( Holothurioidea ), is a marine mollusk that lives by the sea to 8,000 meters. Sea cucumber contains extremely low cholesterol and is a typical high-protein, low-fat, low-cholesterol food. Modern research shows that sea cucumber has the functions of improving memory, delaying gonad aging, preventing arteriosclerosis, diabetes and anti-tumor. In recent years, with the continuous improvement of the living standards of urban and rural residents and the awareness of medical care, the consumption demand of sea cucumber has continued to rise. [0003] At present, there is an upsurge of cultivating sea cucumbers all over the country. With the rapid development of sea cucumber farming...
