Management of jellyfish pond under continuous rainy weather

The continuous rainy weather has a certain impact on jellyfish culture, mainly in water quality control, disease control, bait feeding and so on. How to actively respond to the situation, guide the situation, minimize the negative impact and promote the growth of jellyfish is a problem we have to solve.

1, water quality control. As we all know, water is difficult to fertilize in rainy weather, mainly because of weak light intensity, weakened photosynthesis, reduced algae reproduction speed and even algae lodging. The effects on jellyfish include the increase of microcystins, insufficient dissolved oxygen in the bottom and great stress response. Therefore, the water quality management of jellyfish circle in rainy weather focuses on detoxification (clean water safety), oxygenation (bottom oxygenation) and anti-stress (activation).

Remarks: 1 The lack of oxygen in the early stage of aquaculture does not mean that there is no oxygen.

? Jellyfish are prone to stop and go, pile up in the downwind, steal the top net, swim weak, jump up and down, somersault and other symptoms, so everyone should pay more attention to observation. Apart from the cause of water scarcity, splashing water is effective in most cases.

? Look for the Liyang trademark when buying, and beware of counterfeiting.

2. Disease control. In recent years, vibriosis has become more and more common in jellyfish culture, which affects the normal growth of jellyfish and causes jellyfish to sink to the bottom, so it needs to be paid enough attention. The rainy weather with weak light and low oxygen is more prone to Vibrio outbreak, so rainy weather is the key period for Vibrio prevention and control. The content and activity of bdellovibrio are greatly improved after the upgrade of the excellent peptide, and the prevention and control of vibrio is safe and efficient, which does not stimulate jellyfish and harm algae.

Remarks: The symptoms of jellyfish edge rot appeared in the same period last year.

Step 3 feed the bait. The main reasons for the slow growth of jellyfish in rainy weather are insufficient bait, slow reproduction of natural bait (algae), less zooplankton and insufficient jellyfish and fairies. "Liduoduo" is a live bacterial protein bait specially used to cultivate zooplankton, which has good suspension and can be fully utilized by zooplankton to make up for the shortage of algae. "Yubeiduo" is a fermented bait fertilizer specially designed for the bottom villain fairy. Its particles sink to the bottom, its fertility is mild, and it does not increase ammonia nitrogen and nitrite. As a bait supplement, it can be directly ingested or fertilized with natural bait.

Remarks: 1 I know that it is not good to fertilize water in continuous rainy days, but I have to get fat if I am not fat, and jellyfish can't wait. Look at other people's jellyfish and you will be anxious (next).

Rain or shine fertilizer-good morning-can be poured on the materials together.
