Culture technique of Tiger spot

Tiger grouper is a common species of grouper, which has high nutritional value and is very rich in protein. And low fat content, very suitable for people who are losing weight to eat. At present, the artificial breeding of tiger spot in our country is also gradually developing, but many people do not know how to do it. So the editor brings you the breeding technology of tiger spot today, let's take a look at it!

1. Seedling stocking

Every year from March to May, when the temperature gradually picks up and the water temperature rises to about 18 degrees. The young fish in the greenhouse should be moved to the culture pond at the right time, but before entering the pond, the culture pond should be disinfected. Sodium hypochlorite and other agents can be used as disinfectants. After disinfection, wash with water until the taste of the medicine disappears, and then add water to about 1.3 meters in the culture pond. And also need to disinfect the fish fry to prevent carrying bacteria into the pond, affecting the growth. When stocking, we should pay attention to the breeding density, because the tiger spot has the living habits of gregariousness, hypoxia tolerance and less activity, so it can be cultured intensively.

2. Bait management

Tiger spot is a kind of carnivorous fish, which is mainly fed by fish, shrimp and crabs in artificial culture. But now most tiger spot farming usually uses small mixed fish, and you can also buy special feed for tiger spot in the market. When feeding, the dosage should be reasonably controlled according to the variety of bait and the quantity of breeding, and should not be fed too much. When there is residual bait in the pond, it should be fished out in time to prevent the deterioration of the bait from causing tiger spots to eat by mistake and cause disease. When feeding bait, we should follow the principle of more and less to avoid adverse reactions caused by tiger spots.

3. Water quality management

The quality of water quality is very important to the growth of tiger spot. Poor water quality will slow down the growth rate of tiger spot, decrease the amount of dissolved oxygen, affect the growth of tiger spot, and lead to death in serious cases. The change of water quality is mainly caused by weather and bait pollution. Therefore, we should try to change the water every time we feed the bait every day, and then clean the pool wall, bottom and other places with residual stains. When changing water, first lower the pond water level to about 45 cm, and then let it convect for about two hours and then restore the water level to its original position.

4. Disease prevention and treatment

Tiger spot in the artificial breeding process, the incidence of disease is relatively high. The main cause of the disease is caused by parasitic infections, such as melon worms. Rotifers, etc. There are also bacterial diseases such as Vibrio in seawater. Disease is fatal to tiger spot, so we must do a good job in disease prevention in the process of breeding. What is more important is that during the seedling stage of tiger grouper, we should strengthen the sanitation of the surrounding environment, disinfect regularly, eliminate parasites regularly, take medicine bath on tiger spot, and reduce the incidence of disease.

The above is a brief introduction of tiger spot culture technology, tiger spot culture management is more important, especially in the seedling stage, the cultivation of seedlings is directly related to the growth of tiger spot in the middle and later stage.
