Cause: Disease caused by the lack of vitamin C, all shrimp may occur. Since vitamin C is extremely unstable in feed, although the amount of feed is generally sufficient, there are many factors that contribute to loss. The amount of vitamin C when shrimp is ingested is not much, if the shrimp is in the absence of plankton and aquatic plants Living in the environment, it is possible to suffer from the disease.
Symptoms: Hemolysis and necrosis occur in the diseased shrimp's connective tissue. Shrimp are anorexia and have slow movement and are prone to bacterial infections. Abdominal joints, appendages and shrimps became black at the junction and black plaques appeared in the underlying tissues.
Prevention and treatment: The method of feeding with artificial diets and live bait is used. A certain amount of plankton should be guaranteed in the shrimp pond. Add photosynthetic bacteria to the feed as a precautionary measure. Oral medicine bait in general condition, using vitamin C as 1 ‰ to 2 ‰ dose, continuous feeding for 1 week, observe the curative effect; condition serious oral administration bait vitamin C3 ‰ ~ 4 ‰ dose, continuous feeding for 1 week, can extend the treatment period Until it is fully recovered.
new high-performance sensors can effectively detect smouldering fires It can detect all kinds of indoor smoke. When the indoor smoke volume reaches the alarm concentration, the detector will alarm, the red indicator light will be on, and the buzzer will beep, so as to prompt the user to timely check the causes of the leakage accident and eliminate potential safety hazards.
