How to farm tiger grouper? Detailed explanation of the key farming techniques
Tiger grouper is a common variety of grouper with high nutritional value and a very rich protein content. It is also low in fat, making it very suitable for people who are trying to lose weight. Artificial farming of tiger grouper in our country is currently developing gradually, but many people do not know exactly how to carry it out. So today, the editor brings you the farming techniques for tiger grouper. Let's take a look below!
1. Fry stocking
Every year from March to May, when the temperature gradually rises and the water temperature rises to about 18°C, the young fish in the insulated shed should be moved to the farming pond at the right time. However, before entering the pond, the farming pond must first be disinfected, and disinfectants such as sodium hypochlorite can be used. After disinfection, wash with water until the smell of the agent disappears, then add water to the farming pond to about 1.3 m. The fry also need to be disinfected to prevent them from carrying pathogens into the pond and affecting growth. When stocking, pay attention to the farming density, because tiger grouper has the living habits of being gregarious, tolerant of low oxygen, and low in activity, so it can be farmed at a suitably high density.
2. Bait management
Tiger grouper is a carnivorous fish. In artificial farming, the main baits are fish, shrimp, and crabs. However, most tiger grouper farming today usually uses small trash fish, and special feed for tiger grouper can also be purchased on the market. When feeding, the amount should be reasonably controlled according to the type of bait and the farming quantity, and too much should not be fed. When there is leftover bait in the pond, it should be removed promptly to prevent the bait from spoiling and causing tiger grouper to accidentally eat it and trigger disease. When feeding bait, follow the principle of feeding more frequently and in small amounts to avoid adverse reactions in tiger grouper.
3. Water quality management
Water quality is very important to the growth of tiger grouper. Poor water quality will slow the growth rate of tiger grouper and reduce dissolved oxygen, affecting growth, and in severe cases causing death. Changes in water quality are mainly caused by weather and bait pollution. Therefore, every time we feed bait each day, we should try to change the water once, and then clean the pond walls, pond bottom, and other places with residual dirt. When changing the water, first lower the pond water level to about 45 cm, then let it flow for about two hours before restoring the water level to its original position.
4. Disease prevention and control
In the process of artificial farming, the incidence of disease in tiger grouper is relatively high. The main cause of disease is parasitic infection, such as Ichthyophthirius multifiliis and Trichodina. There are also bacterial diseases such as marine Vibrio. Disease is fatally harmful to tiger grouper, so during farming we must do a good job in disease prevention. More importantly, during the fry stage of tiger grouper, we should strengthen the sanitation of the surrounding environment, disinfect regularly, regularly eliminate parasites, and give tiger grouper medicated baths to reduce the incidence of disease.
The above is a brief introduction to tiger grouper farming techniques. The farming management of tiger grouper is relatively important, especially during its fry stage. The cultivation of fry is directly related to the growth of tiger grouper in the middle and later stages. If you want to know exactly how to cultivate and manage them, you can check related articles!
