Benefits of technology

This patented technology allows creating an environment where we grow seafood without being affected from natural factors like weather or other environmental influences that could affect its quality over longer periods. It achieves this through controlled induced conditionings which allow many small fishes to form clumps instead of growing them together into larger ones with their feet covered up. Additionally, it prevents damage when storing these cloned materials due to poor replication rates resulting in fewer chances of finding new food sources. Overall, this method provides technical benefits such as increased yield compared to traditional methods while maintaining consistently good taste and flavor on freshness levels.

Problems solved by technology

This patented technical solution described involves maintaining highly pure polyplets from sea cucumber plants during winter months when they can still survive without being severely damaged or dying naturally. Additionally, keeping these polyplet populations alive longer helps save valuable resource on their own right while also improving productivity at commercial scales through increased yield rates.

Embodiment

[0028] 1) Acquisition and cultivation of discs: At the end of April, the indoor water temperature was raised to 14°C, and high-quality polyps preserved at 7°C were selected, and the temperature was rapidly raised to 20°C at a rate of 2°C per day to induce the polyps to split reproduce. Both the amount of feeding and the amount of water exchange increased during the period of polyp transverse cracking, and the water was changed by 50% every day. After two weeks, discs were released intensively, and each polyp released 5-10 discs.

[0029] The newborn dish-shaped bodies are cultured with micro-inflating, and after 3-4 days they develop into jellyfish larvae, they are then inflated with large air bubbles, and in 18 days they develop into juvenile stings with an umbrella meridian of about 20 mm. The feeding amount should be 1 hour full of food in the stomach and the density of Artemia nauplii in the water is 10-20 / L.

[0030] 2) Juvenile sting selection: Select 500 young stings w...

Abstract

The invention belongs to the field of aquatic animal breeding and particularly relates to an indoor totally-artificial jellyfish breeding method. The indoor totally-artificial jellyfish breeding method is characterized in that high-quality jellyfish hydroid polyp bodies stored under a low temperature are stimulated so that strobilation of the high-quality jellyfish hydroid polyp bodies can be formed and ephyrae can be generated; all environmental factors are controlled to make the ephyrae grow into adult jellyfishes inside a room. After the jellyfishes grow into the sexual maturity stage, gonads of the jellyfishes are made mature and oviposition and fertilization are carried out through an artificial inducing method, and finally zygotes grow into the ephyrae and indoor totally-artificial jellyfish breeding is completed. A large number of high-quality jellyfish hydroid polyp bodies can be once supplied according to the indoor totally-artificial jellyfish breeding method, the defects that hydroid polyp body supplement rate is low because podocyst breeding efficiency is low and the total number of the hydroid polyp bodies is continuously reduced because a large number of hydroid polyp bodies are separated from boards are overcome, and technical support is provided for storage of high-quality jellyfish seeds.
