How to raise jellyfish?

Jellyfish belong to Scylla, a very beautiful aquatic animal with a body shaped like a transparent umbrella. nowadays, keeping small jellyfish as pets has become more and more fashionable among young people, but many people do not know how to feed. And worry about jellyfish poisonous, how to do? Now let's take a look at how jellyfish are raised.

What do jellyfish eat?

Jellyfish are carnivorous, feeding on plankton, small crustaceans, hirsutes and even small fish. Due to the mechanical and chemical stimulation of food, polyps stretch their tentacles, release thorn sacs to wind, paralyze and poison prey, and then put food into their mouths. Once they encounter prey, they never let go easily.

Are jellyfish poisonous?

Jellyfish are poisonous. Jellyfish is one of the most toxic marine organisms, especially box jellyfish. If it is poisoned, if it is not treated urgently within 0-4 minutes, it will lead to death. According to the survey, tens of thousands of jellyfish are injured by jellyfish in China every year. These patients may develop symptoms such as skin redness and swelling or muscle pain in a short time. In serious cases, patients may have dyspnea, shock or even death. And this is all caused by jellyfish venom.

How to raise jellyfish?

1. Select jellyfish: the toxicity of sea moon jellyfish is much less than that of other dangerous jellyfish (such as box jellyfish). Or jellyfish from jellyfish lake. However, if physically sensitive people accidentally touch jellyfish, they may still have itching and redness caused by contact with the stinging cells in the jellyfish.

2. Mariculture: jellyfish are marine creatures, so they must be farmed with seawater. Change their water every week or so to prevent dirt and microbes from blocking jellyfish and fish from receiving energy and affecting the speed of movement. Be careful not to touch the jellyfish when changing the water, and don't hurry and slow down when adding water.

3. Professional equipment: an aquarium specially designed for marine life, especially jellyfish, special species of jellyfish need to have a certain degree of flow control.

4. Temperature management: thermostats should also be placed in the aquarium to keep the water temperature around 25 degrees Celsius, otherwise there will be problems with its "survival".

5. Feeding management: jellyfish have high requirements for food, and plankton such as Artemia and harvest shrimp (please refer to other experiences for shrimp farming in harvest years) are their favorites. When it is found that the digester and mouth in the jellyfish wings turn orange, it means that the jellyfish is full. The number of times of feeding should be well controlled and should not be too much, as the water quality will easily deteriorate.

6. Light source management: light is an important factor for jellyfish to replenish energy. Some algae in the jellyfish, unicellular Xanthophyta, supply the oxygen produced by their photosynthesis to the jellyfish, while the nitrogenous waste produced by the metabolism of jellyfish happens to be supplied to the unicellular Xanthophyllum in the jellyfish. The relationship between the two is interdependent. Most professional jellyfish aquariums contain coral blue lights, which can provide the photosynthesis of single-celled xanthophyta, and the light time does not need to be specially enhanced. The lighting time does not need to be specially strengthened.

Note: it is recommended that you first master some knowledge of jellyfish culture and then choose whether or not to breed. Due to the limited conditions, the life span of domestic jellyfish is generally no more than 9 months, and you should be responsible for the small jellyfish and yourself.
