Tilapia is resistant to hypoxia and fertilizer, and is not afraid of heat. When the water temperature is 12~13℃, it will get frostbite. The survival temperature is 15~35℃, and the critical temperature is 8.61℃±0.15℃. Therefore, when selecting a site in a reservoir, you must consider choosing the side with water quality fertilizer, shelter from the wind and the sun, and high temperature, instead of placing it at the vent of the reservoir.

Cage structure and layout: It can be made into a 1×1×1 m cage with a mesh size of 3 cm. The bottom of the box is made of dense mesh cloth into a disc-shaped bottom net with a side height of 20 cm to prevent the loss of bait. Install an insect trap at the top 50~30 cm of the fully enclosed net cage and set a black plastic oblique intubation tube or black iron skin tube with a diameter of 10 cm on a corner of the net cover as a bait feeding pipe. Use moso bamboo (10 cm in diameter) to make the overall frame of the cage, and use black braid on the top of the cage to make a hat larger than the lid, which is used to shade the tilapia in the cage to avoid human interference and animals The interference to protect the safe eating of fish. In a dark environment, the amount of fish activity is greatly reduced, which is beneficial to growth. The cages are spaced 2 to 3 meters apart and arranged in a pattern.

Seed release time: The fingerlings can be stocked when the water temperature is about 24℃. If the water temperature is lower than 20℃, it is easy to frostbite the fish. Therefore, release the seeds after the temperature is stable at 20°C, which is conducive to the early start of the fish.

Stocking density: For tilapia with a tail weight of about 40 grams, 330 to 550 tails per square meter are placed in a cage.

Feeding method: The fish that have just entered the box should be fed a small amount of good palatability bait for tame food, a few days later, stable feeding, 4 times a day. The water temperature is 28~32℃, which is the golden water temperature for tilapia to eat, so you need to feed more. Chinese herbal medicine is often mixed in the bait for disease prevention. In the season of flying insects, open the net cover at night, turn on the lights to lure the insects to feed the fish, and add the net cover during the day. It is most useful for fish to eat insects without hurting the body of the fish. The net cover creates a dark environment, and the water is good, and the fish keep growing.
