Method for artificially propagating moon jellyfish

Abstract

The invention relates to a method for artificially propagating moon jellyfish and belongs to a propagating technology of marine organisms. The method comprises the following steps of: feeding female and male parents of the moon jellyfish in the same water body with stable temperature and salinity for 100-150 days; scratching the female parent and the male parent and changing the temperature, the salinity and illumination of the water body; respectively releasing ova and sperms from the female parent and the male parent, wherein the ova and sperms form fertilized eggs, the fertilized eggs develop to form larva plankton and the larva plankton develops for 2-8 days to form hydranths; separately culturing an attachment medium to which the hydranths are attached, keeping the water quality fresh as well as the temperature and the salinity stable; allowing hydranths to become hydranth adults after being fed for 30-80 days; under the conditioned stimulus, releasing a jellyfish larva from the hydranth adult; feeding the jellyfish larva in clear water quality and breeding the jellyfish larva by adopting soft bubbles; allowing the jellyfish larva to gradually grow into young jellyfish after being fed for 7-20 days; and transferring the young jellyfish into a young jellyfish culture tank, keeping the temperature and the salinity constant and allowing the young jellyfish to develop into an adult jellyfish after being fed for 50-100 days.

Description

technical field [0001] The invention relates to a marine organism breeding technology, in particular to a method for artificially breeding moon jellyfish. Background technique [0002] Moon jellyfish, belonging to the coelenterate phylum, the class of the pot jellyfish, and the order of the jellyfish, is also known as the UFO jellyfish in Taiwan. It is distributed in all major oceans of the world. It can be found in the coast of Yantai City, Shandong Province, my country. Adults can be found during July and August. Swarm of moon jellyfish. The moon jellyfish is mainly composed of umbrella body and mouth arm, 98% of the body is water; the umbrella body is colorless and transparent, in the shape of a disc, there are four horseshoe-shaped stomach bags in the middle of the umbrella body, and the umbrella body is covered with net-like radiation. There is a circle of slender tentacles on the edge of the umbrella body; there are four ribbon-shaped mouth wrists under the umbrella bo...
