How long is the tilapia farming cycle and how to farm tilapia

The breeding cycle of tilapia is generally 5-6 months. Tilapia is a tropical fish with delicious meat, few bones and high protein content. It is one of the main farmed aquatic products in my country. The fry are released in the period when the temperature rises after the spring, generally around mid-April. After the fry are released, the breeding time of tilapia can be shortened by increasing the water volume, reducing the fertility of the water quality, using aerators, and preventing and controlling fish diseases.

1. How long is the tilapia farming cycle?

1. The breeding cycle of tilapia is about 5-6 months. Generally, the fry are released in mid-April and can be harvested around October.

2. Tilapia is native to Africa and is a tropical fish. It is also the main farmed aquatic product in my country. The meat is delicious and has few bones. The main breeding areas are Guangdong, Guangxi, Hainan and other areas with higher temperatures. They are generally raised in ponds.

3. The farming cycle of tilapia can be shortened by increasing the water volume, reducing the water fertility, using aerators, etc., so that tilapia can be put on the market for sale earlier.

2. Tilapia Farming Methods

1. Site selection for breeding pond:

(1) Generally, you need to choose a pond of 667-1334 square meters. The pond should be rectangular in shape with a flat bottom. Sandy loam is preferred.

(2) The pond must have convenient drainage, be pollution-free, and face the sun. The water depth must be maintained at around 1.8-2.5m during breeding, and an aerator must be installed to supply oxygen to the fry.

(3) Before stocking fish, the fish pond needs to be cleaned 7-10 days in advance, then drained and exposed to the sun. The dry pond should be disinfected with lime powder. After cleaning and disinfection, fermented fertilizer should be added to cultivate plankton.

2. Seedling raising and stocking:

(1) You need to choose fry with smooth body surface, strong physique, neat size, plump body and a size of about 5 cm. Before stocking, the fry need to be soaked in 5% salt water or 5-10 mg potassium permanganate solution.

(2) One tilapia fry can be placed in one cubic meter of fish pond, and 40 to 50 bighead carps weighing 50 grams can be placed per acre, and 30 to 40 silver carps weighing 30 grams can be placed per acre.

3. Feeding and management:

(1) Tilapia likes oxygen, so it needs to be equipped with an aerator for daily feeding. One aerator can be installed for every 5 mu of pond to ensure that the tilapia does not float.

(2) Before the tilapia fry weigh 150 grams, use fertilized water for breeding and apply fertilizer once a week. After 2-3 months of breeding, when the weight of each tilapia is 250 grams, it is necessary to change the breeding method and feed it with full-price and well-proportioned multi-fish feed. In the middle and late stages, when each tilapia weighs 1 kilogram, it is necessary to ensure the freshness of the water quality to increase the appetite of the tilapia and achieve the goal of rapid growth.

What should be paid attention to in high temperature breeding of tilapia? What should be paid attention to in high temperature breeding of tilapia?

1. Although the continuous high temperature weather is conducive to the growth of tilapia, bacterial diseases such as streptococcus and Aeromonas are also prevalent at this time. Recently, a large number of streptococci and Aeromonas were still found in the bacterial isolation and identification of diseased tilapia.

2. Continuous high temperature causes blue algae to multiply in large numbers, resulting in dark green water color, deterioration of water quality, increase of ammonia nitrogen and nitrite, decrease of dissolved oxygen, causing hypoxia and inducing various diseases.

3. In weather with uncertain weather, the pond is prone to algae overgrowth, which will accelerate the deterioration of water quality and bottom quality, causing tilapia hypoxia and poisoning.

4. In rainy weather, the upper water temperature drops sharply, causing upward and downward convection of the water body, which causes the water in the pond to return to the bottom and affect the growth of tilapia.

5. The low pressure before the typhoon and the heavy rainfall when the typhoon lands will cause drastic changes in the pond environment, leading to bottom return, algae overturning, hypoxia, stress and other situations.
