Problems solved by technology

Due to the increase of nursery farms, the demand for seed ginseng has increased, but after generations of cultivation, sea cucumber has problems such as weakened heritability, poor resistance to stress, and degradation of traits.
In addition, sea cucumbers cultured in ponds and intertidal zones are high-density and intensively cultured, so the amount of eggs laid is lower than that of species in natural sea areas. In this way, the quality of the eggs produced will decline, which will inevitably affect the metamorphosis of each stage. Rate

Embodiment 1

[0027] The cultivation method of the sea cucumber seed ginseng of the present embodiment may further comprise the steps:

[0028] 1. Harvesting

[0029] Harvesting season: In November of the Gregorian calendar every year, when the seawater temperature in the natural sea area reaches 10-12°C, the water depth in the sea area is 5-10m, and the bottom is sandy mud and gravel. Seaweed resources such as sargassum are abundant, which is an excellent habitat for wild sea cucumbers;

[0030] Harvesting: Diving and harvesting by divers. When harvesting, the following items need to be paid attention to:

[0031] ① The number of harvested at one time should not be too much, and the stimulation should be reduced as much as possible to avoid mechanical damage caused by the backlog of sea cucumbers;

[0032] ② The hands of divers and operators, or vessels, tools, etc. should not be in contact with oil stains;

[0033] ③ Keep the water quality in the holding tank on board fresh and change ...

Abstract

The invention relates to a method for culturing a Stichopus japonicus seed, which belongs to the technical field of a Stichopus japonicus seed culturing method and comprises the following steps of (1) fishing and catching; (2) screening; (3) transporting and (4) culturing the Stichopus japonicus seed. According to the method for culturing the Stichopus japonicus seed disclosed by the invention, the culturing process is easy to operate, the Stichopus japonicus seed is scientifically selected and fished and caught in advance; the Stichopus japonicus seed can be matured in advance and lay eggs by utilizing the method of indoor heating and accelerating, thus, large-scale seeds can be cultured in the same year, and the produced Stichopus japonicus seed has enhanced hereditary capacity, strong resistance and good property; moreover, as the feed of the Stichopus japonicus seed and the water temperature and the water quality in the Stichopus japonicus culturing pond are strictly controlled, the fecundity of the Stichopus japonicus is better than that of the Stichopus japonicus cultured in the pond and the intertidal zone, thus, the laid eggs have good quality and the distortion ratio at each stage is high.

Description

technical field [0001] The invention relates to a method for cultivating sea cucumber seed ginseng, and belongs to the technical field of seed ginseng cultivating methods. Background technique [0002] At present, the selection of ginseng species in the nursery includes pond cultured sea cucumbers and intertidal cultured sea cucumbers. Although the eggs of parent ginseng can be fertilized and developed normally, the metamorphosis rate and survival rate are greatly reduced when metamorphosis. Due to the increase of nursery farms, the demand for seed ginseng has increased, but after generations of cultivation, sea cucumbers have problems such as weakened heritability, poor resistance to stress, and degradation of traits. In addition, sea cucumbers cultured in ponds and intertidal zones are high-density and intensively cultured, so the amount of eggs laid is lower than that of species in natural sea areas. In this way, the quality of the eggs produced will decline, which will ...
