Embodiment 1

[0018] The sea cucumbers were harvested by diving and temporarily kept in a 300L water tank. During this period, the water temperature was slowly adjusted to 12°C. After the sea cucumbers adapted to the indoor conditions, the sea cucumbers were fed, and 20 sea cucumbers were stocked in each tank. Mix 30 parts by weight of kelp powder (sun-dried kelp powder), 15 parts by weight of wheat bran, 15 parts by weight of soybean powder, and 10 parts by weight of fish meal, gradually add water and cook for 20 minutes, and add 25 parts by weight of sea sand after cooling , 3 parts by weight of oyster shell powder, 1 part by weight of shrimp shell powder, 0.5 parts by weight of multivitamins, and 0.5 parts by weight of inorganic salts are mixed evenly, and evenly sprinkled according to the ratio of sea cucumber wet weight 10%. Clean up the residual bait and feces every day, and feed fresh bait.

[0019] The average gonad index of the parents is 12.0%-19.6%. When the reference ratio of se...

Embodiment 2

[0022] The sea cucumbers were harvested by diving and temporarily kept in a 300L water tank. During this period, the water temperature was slowly adjusted to 12°C. After the sea cucumbers adapted to the indoor conditions, the sea cucumbers were fed, and 20 sea cucumbers were stocked in each tank. Mix 29 parts by weight of kelp powder (sun-dried kelp powder), 16 parts by weight of wheat bran, 14 parts by weight of soybean powder, and 11 parts by weight of fish meal, gradually add water and cook for 20-30 minutes, and add 24 parts by weight of Sea sand, 4 parts by weight of oyster shell powder, 1.1 part by weight of shrimp shell powder, 0.4 part by weight of multivitamin, and 0.6 part by weight of inorganic salt are mixed evenly, and evenly sprinkled according to the proportion of 10% of the wet weight of sea cucumber. Clean up the residual bait and feces every day, and feed fresh bait.

[0023] The average gonad index of the parents is 9.1%-19.6%. When the proportion of sexuall...

Embodiment 3

[0026] The sea cucumbers were harvested by diving and temporarily kept in a 300L water tank. During this period, the water temperature was slowly adjusted to 12°C. After the sea cucumbers adapted to the indoor conditions, the sea cucumbers were fed, and 20 sea cucumbers were stocked in each tank. Mix 31 parts by weight of kelp powder (sun-dried kelp powder), 14 parts by weight of wheat bran, 16 parts by weight of soybean powder, and 9 parts by weight of fish meal, gradually add water and cook for 20-30 minutes, and add 26 parts by weight of Sea sand, 2 parts by weight of oyster shell powder, 0.9 part by weight of shrimp shell powder, 0.6 part by weight of multivitamin, and 0.4 part by weight of inorganic salt are mixed evenly, and evenly sprinkled according to the proportion of 5-10% of the wet weight of sea cucumber. Clean up the residual bait and feces every day, and feed fresh bait.

[0027]The average gonad index of the parents is 15%-20%, and when the reference ratio of s...

Abstract

The invention discloses a California red holothurian artificial breeding method. The method includes: feeding maturity promoting feedstuffs into an aquaculture tank to cultivate holothurians, adding 1% spirulina liquid into the holothurian aquaculture tank when holothurian gonad index exceeds 15%, and well mixing for cultivation. By adoption the scheme for artificial breeding of California red holothurians, nutritional requirements of quick gonad development of the California red holothurians can be met by the maturity promoting feedstuffs in scientific proportion, and the maturity promoting feedstuffs effectively enable quick maturity of the holothurians; the spirulina liquid can effectively stimulate spermiation of male holothurians and ovulation of female holothurians to realize synchronicity of spermiation and ovulation so as to guarantee reliability in artificial breeding of the California red holothurians.

Description

technical field [0001] The invention relates to the field of artificial cultivation of California red ginseng, in particular to a method for artificial cultivation of California red ginseng. Background technique [0002] California red ginseng (a type of sea cucumber) is native to North America. It is distributed from California to Alaska from shallow water in the intertidal zone to a water depth of 249 meters. This species of sea cucumber is an important economic species in British Columbia, Canada, Washington State and Alaska in the United States. , the products are mainly sold in China, the United States, Japan, South Korea and other places. The natural reproduction of wild populations of sea cucumbers only occurs in North America from July to August. At present, the technology of promoting maturation and raising seedlings of the parents of this species of sea cucumbers is still in the exploratory stage in its origin. Therefore, it is extremely important to develop a met...
