Catfish is not a strange food to Vietnamese people. Catfish appears in daily meals, providing abundant nutrition and equally attractive taste. Recently, there have been many large scale farming of catfish in tarpaulin tanks. So Techniques for raising catfish in tarpaulin tanks How is it implemented? Let’s learn about this topic with us.
Prepare the aquarium
Choose a location to place the lake (This location should be well ventilated). Then dig the lake according to the size, design depth. In addition to digging ponds, farmers can also design their own frames to shape the lake with iron or with bamboo or wood. Raising catfish in a pond lined with canvas, we will dig the lake in a circular shape. Because the circular lake has a high degree of centrifugation, it is easier to collect waste as well as discharge it.
Strip 1 layer of fine sand on the bottom of the lake, then put a geotextile underneath and then a PVC tarpaulin to the bottom of the lake.
Place the stones just right on the bottom of the tank to shape the aquarium
Put water in the lake and proceed to the next step is to choose the seed to raise
Choose fingerlings
To successfully implement the technique of raising catfish in tarpaulin tanks, the selection of fingerlings is extremely important. Catfish are easy to raise and grow quickly, but in order for the fish to develop well, the prerequisite is to choose healthy seed. Healthy fish are bright colored fish, without sores, scratches, healthy swimmers.
There are 4 types of catfish: black catfish, yellow catfish, tilapia and white catfish. Among them, black catfish and yellow catfish are the most valuable because their meat is the most delicious. Black catfish is usually raised in the North while yellow catfish is usually raised in the South.
Note, before releasing fish into the pond, farmers should mix pots of salt water about 0.3 – 0.5%, soak the fish for 10-15 minutes to remove all bacteria and fungi on the fish. That’s the fastest growing fish.
Notes in the process of raising fish
The technique of raising catfish in tarpaulin tanks is quite simple and easy to implement, but households should also note the following issues:
Catfish are omnivorous fish, food for catfish is very easy to find such as juveniles (should be boiled before feeding), bran, corn, chicken manure… However, in the first 3 months of life. Catfish needs a very high amount of protein to grow, so people can combine the above foods with processed industrial food.
During the rearing process, the water should be changed regularly, the water before being put into the tank should be settled in a settling tank first, ensuring clean water quality for the fish to grow.
When raising catfish in a pond lined with canvas, people can pay attention to add the necessary vitamins and monitor the fish continuously throughout the farming process to detect diseases promptly and handle them quickly.
Above is a technical guide to raising catfish in a tarpaulin tank that is quite detailed and easy to follow. Hope you can successfully apply this model to get rich from catfish easily.
