Embodiment 1

[0013] The acquisition of embodiment 1 Papua nitrous polyp

[0014] Using 10 Babu nitrous jellyfish imported from Malaysia as parents, the Papu nitrous jellyfish are dioecious and mixed in a water body of 1×0.75×0.8m 3 In a dark plastic bucket, keep the water temperature at about 27°C, and keep the jellyfish in a completely dark environment overnight with shading. Swimming jellyfish sperm were found in the water after 2-5 hours of polyculture, and then fertilized in the jellyfish and developed into fertilized eggs. After 16 hours, most of the fertilized eggs developed into floating larvae floating on the water surface. At this time, take out the jellyfish and put it back into the original breeding tank, scoop up the floating larvae from the water surface and put them in fresh seawater of the same temperature. Put about 500 floating larvae and two polyethylene attachment sheets in each 1L beaker, and then place the beaker in a constant temperature culture. Continue to grow in ...

Embodiment 2

[0017] A method for producing and cultivating the dish-shaped body of Nitrites jellyfish. The polyps of Nitrites jellyfish are obtained by the method described in Example 1. The polyps were cultured in a 1L beaker in a constant temperature biochemical incubator at 20-24°C, adsorbed on polyethylene slides, and fed 1-5 artemia nauplii hatched for 24 hours per milliliter of water per day, and changed the water after 3 hours of feeding. 8000Lux8h light and 16h dark alternating light to ensure sufficient number of zooxanthellae in the body. When the temperature is raised to 25-27°C, the hydra will undergo transverse fissures in 2-10 days, producing a disc each time. After splitting, the tentacles of the polyp disappeared, and after 1-10 days of feeding, the original shape was restored, and the second single-disc transverse split occurred. The polyp survival rate is 100%.

[0018] The diameter of the newly split disc is 1-3 mm, with weak swimming ability, floating or depositing at...

Abstract

The invention discloses a method for generating and cultivating papuan jellyfish ephyrae and belongs to the field of artificial feeding and breeding of ornamental marine animals. A papuan jellyfish hydranth transversely cracks to generate an ephyra every time, the ephyra is continuously cultivated for 5 to 10 days, and second-time single-ephyra transverse cracking is generated; the ephyra which just cracks is bred in a container where bubbles drive water flow, one to three artemia nauplii are fed with each milliliter of water every day, and the water is changed after the artemia nauplii are fed for 2h. Cultivation conditions are as follows: the water temperature is 20 to 27 DEG C, 8000Lux 8h illumination 16h dark alternation is carried out, 5 to 10d ephyrae are transformed into jellyfish bred bodies and the jellyfish bred bodies are moved into a circulation cylinder where a water pump drives the water flow. According to the method, transverse cracking of the papuan jellyfish hydranth is promoted in an artificial environment, the ephyrae are generated and are further cultivated to obtain the jellyfish bred bodies and adults, and the situation that exhibition in an aquarium is maintained by virtue of fishing is solved.

Description

technical field [0001] The invention belongs to the field of artificial feeding and breeding of ornamental marine animals, and in particular relates to a method for producing and cultivating the dish-shaped bodies of Papua nitrous jellyfish. Background technique [0002] Jellyfish have different shapes and poses, and have high ornamental value. In recent years, they have been artificially raised and displayed in aquariums at home and abroad. In nature, due to the complex growth and reproduction methods of jellyfish, which can explode in a short period of time, endangering the ecological balance, the simulation display in an artificial environment is of scientific and educational significance. [0003] At present, the researches on jellyfish reproduction are mainly focused on the jellyfish and jellyfish, and there are very few studies on the highly ornamental jellyfish. Contents of the invention [0004] The technical problem to be solved by the present invention is to pro...
