Embodiment 1

[0014] A method for obtaining the polyps of Papua nitrous jellyfish, using 10 Papua nitrous jellyfish polyps imported from Malaysia as parents, Papua nitrous jellyfish dioecious, 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 i...

Abstract

The invention relates to a method for obtaining hydranths of mastigias papua, and belongs to the field of artificial feeding and propagating of ornamental marine animals. The method comprises the steps of: culturing parents in a manner of completely being away from light, wherein the culturing water temperature is 25-28 DEG C, enabling the cultured parents to be fertilized, and when fertilized eggs grow into planula larvas floating and swimming on a water surface, taking out the parents; shifting the planula larvas into fresh seawater with the same temperature, at the same time, putting attaching pieces in the fresh seawater, wherein the putting density is that 400-600 planula larvas and two attaching pieces are put in each one liter of a container, and culturing the planula larvas at a constant temperature; when the planula larvas grow into the hydranths with 4 feelers in an attaching manner, beginning to feed the hydranths with artemia nauplii every day, after feeding the hydranths with the artemia nauplii for 2.5-3.5 hours, completely changing water, when the hydranths grow to have 16 feelers, controlling the culturing temperature to be 20-27 DEG C, and extending the number of the hydranths through asexual reproduction. According to the method disclosed by the invention, the hydranths of the mastigias papua can be cultured in batches, and the requirements of showing, enjoying and researching the hydranths of the mastigias papua can be met. The breeding blank of the mastigias papua is filled.

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 obtaining polyps of 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 provide a method for obtaining the polyp ...
