Jellyfish pond management in continuous rainy weather

Continuous rainy weather has had a certain impact on jellyfish breeding, mainly in water quality control, disease prevention and feed feeding. How to actively respond, take advantage of the situation, minimize negative impacts, and promote the growth of jellyfish is a problem we need to solve.

1. Water quality control. As we all know, it is difficult to fertilize water in rainy weather. The main reason is that the light intensity is weak, photosynthesis is also weakened, the algae reproduction rate decreases, and even algae collapse occurs. The effects on jellyfish include increased algal toxins, insufficient dissolved oxygen in the bottom layer, Great stress response etc. Therefore, the water quality management of the jellyfish circle in rainy weather focuses on detoxification (clear water), oxygenation (bottom oxygenation), and anti-stress (activation).

Remarks 1. Hypoxia is rare in the early stage of breeding, but it does not mean that it is not present.

? 2. Jellyfish are prone to stop-and-go, gather in the lower air outlet, steal the top net, swim weakly, and move up and down. Please pay more attention to symptoms such as scurrying and somersaulting. Except for the reasons caused by water thinning, in most cases, Bishui is safe and effective.

? 3. Look for the Liyang trademark when purchasing and beware of counterfeiting.

2. Disease prevention and control. In recent years, vibriosis has become more and more common in jellyfish breeding. It may affect the normal growth of jellyfish, or cause the jellyfish to fall to the bottom, which requires sufficient attention. Vibrio is more likely to break out in rainy weather, low light, and low oxygen environments, so rainy weather is a critical period for the prevention and control of Vibrio. After the upgrade of Youtide, the content and activity of Bdellovibrio have been greatly improved. It prevents and controls Vibrio, is safe and efficient, has no irritation to jellyfish, and does not harm algae.

Note: Symptoms of jellyfish edge rot appeared in the same period last year

3. Feeding bait. The main reason why jellyfish grow slowly in rainy weather is insufficient food. Natural food (algae) reproduces slowly, resulting in fewer zooplankton. There are not enough jellyfish and jellyfish to eat. "Libaiduo" is a live mycoprotein bait specially designed to cultivate zooplankton. It has good suspension properties and can be fully utilized by zooplankton to make up for the lack of algae. "Yubaiduo" is a fermented feed fertilizer specially designed for the bottom fairy. The particles sink to the bottom, the fertility is mild, and it does not increase ammonia nitrogen and nitrite. As a feed supplement, it can be eaten directly and can be used to cultivate natural feed in fertilized water.

Remarks: 1 We all know that it is not easy to fertilize and water in continuous rainy days, but you need to fertilize even if you don’t want to. Jellyfish can’t wait. Just look at other people’s jellyfish and you will be anxious (picture below)

2Use fertilizer for rain or shine - Algae Ansheng - can be poured on the materials at the same time
