Preservation method of jellyfish

Buy jellyfish and store them directly with salt.

Fresh jellyfish are rich in water, thick in skin and contain toxins. Only after eating triple salt and alum salt (usually called trident) are fresh jellyfish dehydrated for three times, so that the toxins are discharged with water.

Jellyfish is reddish or yellowish, uniform in thickness and tough, and can't be squeezed out by force. This jellyfish is edible. When you go to Haitang City, you will meet jellyfish that have not been treated or treated with 1-2 times salt. You should not try or buy them.

Aquaculture management of jellyfish

1, water quality management

Jellyfish culture is different from other marine treasures culture, which does not need artificial feeding, but fertilizes the pond before releasing the seedlings to maintain the suitable bait biomass in the water body. After the pond is fertilized with water, the water body should be stable for 5 days, and water should be added after the larvae gradually adapt to the environment. In the later stage, every time water is added to change water, it should be kept within 15% of the total water body, and the amount of water exchanged should be gradually increased with the growth of individuals. The principle of changing water is to change less and change more.

2. Daily management?

First, patrol the pool 1 time in the morning and evening, carefully observe the environmental changes, water color and jellyfish activities, and take timely measures when problems are found;

Second, strengthen the detection work, starting from the water inflow in the aquaculture pond, measure the salinity and pH value of the water body every day, and measure the minimum and maximum water temperatures of the pond water at dawn and afternoon, and make records;

The third is to observe the growth of jellyfish at any time, monitor the change of water quality and the biomass of plankton in the water, and do a good job in the determination of relevant data to ensure the smooth production.
