Embodiment 1

[0016] A method for artificially cultivating reef-dwelling sea cucumber seedlings in a small water body, the method comprising the following steps:

[0017] (1) Pro-ginseng to promote ripening: In late June 2017, the full-bodied wild sea cucumber with a body weight of more than 400g and a body length of more than 20cm was intensively cultured, and live Chaetoceros, live benthic Amphitheater and spirulina were added. Nutritional strengthening such as algae powder for 10 days;

[0018] (2) Induced labor and wet fertilization: Scatter the wild yuzu sea cucumbers into a clean bucket so that the sea cucumbers do not overlap each other, dry in the shade for 1.5 hours, and then pump in seawater to impact the ginseng with running water along the wall of the barrel, and add water to 1.0m Deep, every 30 minutes to check whether the male ginseng has ejaculated; put all the ejaculated male ginseng into a new seawater bucket as a semen-producing bucket; some male ginseng began to ejaculate...

Abstract

The invention discloses a method for artificial breeding of reef-dwelling young holothuria leucospilota in a small water body. According to the method, through bait and water quality management in keystages such as the pelagic stage, the metamorphosis settlement stage and the young holothuria leucospilota stage, artificial breeding of young holothuria leucospilota is achieved, artificial reproduction and releasing of holothuria leucospilota are made possible, the restoration of the marine benthic ecological environment of the South China Sea is facilitated, and basic conditions are provided for further development and utilization of biological resources of holothuria leucospilota.

Description

Technical field: [0001] The invention relates to the technical field of aquaculture, in particular to a method for artificially cultivating reef-dwelling sea cucumber seedlings in a small water body. Background technique: [0002] Holothuria leucospilota belongs to the genus Holothuria of the family Holothuriidae, and is a dominant species in the southern waters of my country. Yuzu sea cucumber mainly feeds on organic debris in the seabed sediment, which can accelerate the material cycle of the marine benthic ecological environment and has important ecological value. In addition, Yuzu sea cucumber is edible and can be used as medicine, which has certain economic value. It is of great significance to artificially breed Yuzu sea cucumber and realize large-scale multiplication, which can have both ecological and economic benefits. At present, the artificial breeding technology of Yuzu sea cucumber has not yet completely broken through, and the problem of artificial seedling cu...
