CATDOLL : CATDOLL: Jellyfish breeding rack?

1. How to make a jellyfish breeding rack?

How do jellyfish reproduce? Answer: Larvae fertilized in the mother's body or in the water by themselves actively display the spirit of self-improvement. Larvae will slowly sink to the sand, seaweed or rock cliffs on the seabed, trying to avoid being washed away by the current. Then the larvae slowly grow up to 16 tentacles. With their natural "many hands", the larvae constantly suck in the water, eating plankton or plants that are smaller than themselves to maintain their lives. When the jellyfish larvae absorb enough nutrients to support asexual self-reproduction, the mysterious asexual reproduction can begin. The shape of the larvae's body can be divided into two major parts, the "upper body" is the feeding tentacles, and the "lower body" is a long column. In this column part, the larvae gradually grow buds that are exactly the same as itself because of the sufficient nutrients in its body. Then the buds replicate themselves, forming a conjoined larvae with sometimes up to eight branches. The cycle passed down from generation to generation is endless. Although jellyfish are marine creatures, they are not very good at swimming and can only float and sink with the current. Strong winds and rough waves can smash them to pieces at any time. When the spring comes with no wind and no waves and warm and gentle weather, the conjoined larvae will take the opportunity to come out one by one. After leaving the hard object they are attached to, each independent larva will release a hormone containing iodine to accelerate its transformation into a mature jellyfish. At this time, their appearance also changes from the appearance of a worm to the appearance of a common jellyfish. Mature jellyfish follow the cycle of their ancestors again, lay eggs in the water, and reproduce from sexual to asexual reproduction. They continue to live in this unique ecology that has been inherited for billions of years, and the cycle continues, fully exposing the wonderful side of asexual reproduction in the biological world. And since jellyfish have such a short lifespan, does the jellyfish museum in Ocean Park have to be changed every day? Answer: Jellyfish are beautiful in shape, but they only live for six to eight months, so Ocean Park has to continuously breed jellyfish for display purposes.

2. Why does the increase in pollution sources lead to the massive reproduction of jellyfish?

Because the ocean is polluted, the amount of organic matter in the ocean increases, and plankton and plants multiply in large numbers, so there is more food for jellyfish, and the jellyfish reproduce at an alarming rate.

3. What kind of jellyfish is this? What kind of water should be used to raise it? How to prepare this water? How to breed it?

The moon jellyfish or red moon jellyfish can be raised in seawater by adding seawater salt to purified water.

4. Which domestic company is engaged in jellyfish farming?

Qingdao Longgong Ocean Ranch Ecological Restoration Engineering Co., Ltd. is currently an enterprise with jellyfish breeding and jellyfish farming technology. The company is also a licensed manufacturer for the 2014 Qingdao World Horticultural Exposition.
