Problems solved by technology

However, artificially stimulated ginseng has a low emission rate and ovulation rate after induced production. In order to obtain enough fertilized eggs, it is often necessary to cultivate a large number of ginseng, resulting in waste of breeding space, labor and cost.

Embodiment 1

[0022] A method for improving the emission rate and ovulation amount of sea cucumber seed ginseng, the steps are as follows:

[0023] 1. Harvesting and screening of ginseng

[0024] At the beginning of November in the Gregorian calendar, when the seawater temperature in the sea cucumber breeding pond drops to 10-12°C, the sea cucumber in the pond is harvested. Select individuals with a body weight of more than 200 g, good vitality, no disease, and no damage from the collected sea cucumbers as seed ginseng.

[0025] 2. Ginseng cultivation

[0026] Transport the selected species of ginseng to the indoor cultivation tank for cultivation. Initially cultivate at natural water temperature. When the water temperature drops to 2-3°C, keep the water temperature for 3 days, and then increase the temperature at a rate of 1°C / d until it reaches 6°C. , cultivated at a constant temperature for 6 days, and then raised to 10°C at a rate of 0.5°C / d. After 6 days of constant temperature incub...

Abstract

The invention discloses a method for increasing the emission ratio and ovulation amount of seed stichopus japonicus and belongs to the technical field of ocean aquatic animal culture. The method for increasing the emission ratio and ovulation amount of the seed stichopus japonicus comprises the following steps of screening and culture of the seed stichopus japonicus, serotonin treatment and spawning induction of the seed stichopus japonicu. According to serotonin treatment, based on the injection dose of 20-200 microgram / gram of the seed stichopus japonicus by weight, a serotonin solution is injected into the body cavity from the back of predelivery stichopus japonicus at the constant temperature, and injection is conducted once every 5-20 days in the later period. The method has the advantages that the serotonin is free of toxicity and safe to use; the whole induction treatment process is easy to operate and implement; the emission ratio and ovulation amount of the female seed stichopus japonicus can be effectively increased, the cost of seed stichopus japonicus culture is lowered, and the economic benefit of stichopus japonicus seedling raising is improved.

Description

technical field [0001] The invention belongs to the technical field of marine aquatic animal cultivation, and in particular relates to a method for improving the discharge rate and ovulation amount of sea cucumber species. Background technique [0002] Sea cucumber (Apostichopus japonicus Selenka), belonging to the phylum Echinodermata, class Holothuroidea, family Stichopodidae, genus Apostichopus, has high nutritional health care and medical value. Sea cucumber is one of the species with the highest output value in my country's aquaculture industry. my country initially established the sea cucumber seed breeding technology in the 1980s. After that, for a long period of time, the seed ginseng used for sea cucumber seed breeding mostly used pond culture or adult ginseng from natural sea areas. After 2000, the artificial maturation technology of sea cucumber species was gradually established. The sea cucumbers were cultivated indoors, and the development of the gonads of sea ...
