Description

Technical Field

[0001] The invention relates to the technical field of aquaculture, and in particular to a formula of feed for rapid aquaculture of jellyfish and a feeding method. Background Art

[0002] The hair-shaped jellyfish, also known as the lion's mane jellyfish, belongs to the phylum Cnidaria, family Cynozoa. It is named for the orange-yellow tentacles around its mouth that are like flowing manes. The hair-shaped jellyfish is beautiful in appearance and large in size, symbolizing an elegant life and noble temperament. It is the most spiritual and aristocratic life in the ocean. In developed countries, the hair-shaped jellyfish is often used in the decoration of high-end business and entertainment venues because of its expensive price, brilliant colors and elegant rhythm under the light. It is a symbol of wealth and taste. It can also be seen in some high-end restaurants and bars. Guests can enjoy the hair-shaped jellyfish while dining with friends, which is very effective.

[0003] The hair-shaped jellyfish includes two different life generations, the asexual polyp generation that lives a sessile life and the sexual hair-shaped jellyfish generation that lives a planktonic life. The hair-shaped jellyfish are dioecious, and the sperm is discharged from the mouth of the male individual, enters the body through the oral cavity of the female individual and combines with the egg. The fertilized egg flows down the water to the edge of the oral arm and develops into a planktonic larvae. The planktonic larvae leave the female hair-shaped jellyfish, attach foreign objects with their front end, and develop into early polyps. The polyps continuously generate new polyps by budding reproduction, and after a long nutritional period, they develop into a bowl-mouthed larvae and begin to undergo continuous transverse division, forming many stacked segmental disks to become a transverse body. The segmental disks of the transverse body fall off to form a disc-shaped body, which further develops into a juvenile hair-shaped jellyfish.

[0004] With the maturity of jellyfish breeding technology and hair-shaped jellyfish breeding equipment, hair-shaped jellyfish have entered thousands of households in China as a new favorite for viewing, and the demand for hair-shaped jellyfish in the aquarium market is increasing. In addition, the tentacle toxin of hair-shaped jellyfish has been proven to have efficient hemolytic activity, which has great scientific research value in the treatment of cardiovascular and cerebrovascular diseases, thrombosis, anti-cancer and tumor suppression, and the market demand for hair-shaped jellyfish is increasing.

[0005] At present, the artificial breeding of hair-shaped jellyfish mainly adopts the traditional breeding method of jellyfish. The selection of bait, feeding method and water quality are not conducive to the growth and development of hair-shaped jellyfish larvae, resulting in slow growth of hair-shaped jellyfish larvae, low survival rate and high breeding cost, which makes it difficult to meet market demand.
