What to do if the prawns don’t eat?

Prawns are the most common type of shrimp in people's daily lives. This type of shrimp is popular because of its delicious taste, rich nutrients and moderate price. There are many people raising shrimps, and some people will encounter the situation where shrimps do not eat food. This has a great impact on the growth and development of shrimps, so people need to pay special attention and deal with it in time. Here we will introduce what to do if shrimps don’t eat.

When there are fungi on the gill filaments of shrimp, the efficiency of oxygen exchange in the water through the gill lamellae is weakened. When the oxygen supply in the blood is insufficient, oxygen is consumed to digest food, and the shrimp will stop eating out of instinct (fishing is a good experiment. When the sky is high and the air pressure is high, the dissolved oxygen in the water is sufficient, and fish are easy to catch; when the temperature is hot and the air pressure is low, the dissolved oxygen in the water is low, and it is difficult to catch fish). For the swelling of the gill filaments, if it is caused by fungi, you can use Grammy's Herbal Gubenkang (fermented Chinese medicine)

For internal or external use, mix one bottle with 40 kilograms of material and use it for 5 consecutive days. For external use, use one bottle in two acres of water.

Digestive enzymes are needed to digest food in the intestines. Within the appropriate temperature range, the digestive enzymes of shrimps will increase in efficiency as the temperature rises. When the temperature is low, the digestion rate is very slow, so the amount of food eaten by shrimps in winter will be greatly reduced, or they will stop eating. At normal water temperature, when inflammation, parasites, etc. cause the function of secreting digestive enzymes to weaken, or the pipelines that transport digestive enzymes are blocked, such as liver inflammation, the digestive enzymes cannot enter the intestines. The intestine is an important organ for shrimps, absorbing nutrients, taking in medicines, defending against diseases, and defecation. The mucosal layer in the intestine is the forefront of absorption and defense against diseases. If the intestinal mucosa becomes thinner or damaged, it will affect the operation of various intestinal functions of shrimps, and easily lead to the invasion of pathogens and the intake of nutrients. Therefore, protecting the intestine is an important thing in the process of shrimp farming.

When exogenous polluted water flows in, or a large amount of organic matter and humus such as leftover bait and feces accumulates at the bottom of the water, when there is insufficient dissolved oxygen in the water, a large amount of toxic and harmful substances will be generated under the action of microorganisms, causing discomfort to the shrimp, affecting their feeding and causing a reduction in their feed intake. The solution is to use bacteria to regulate the water quality.
