How long does it take to grow tilapia from fry to one kilogram? Which species is best?

If the fry is 2-4cm long, it usually takes about 1 year to grow it to 1 catties, while the fry of 3-5cm long needs about 5-8 months. However, due to the different breeding techniques, breeding environment, body length of tilapia and other factors, the specific breeding time needs to be determined according to the actual situation. Before breeding, it is necessary to build a breeding pond in a place with convenient drainage and sufficient sunlight, clean and disinfect the pond, cultivate plankton, and then release the fry when the water temperature rises to above 18°C.

How long does it take to grow tilapia from fry to one kilogram?

1. Breeding time

The time required to raise tilapia fry to 1 jin generally depends on the length of the fry. For example, it usually takes about 1 year for fry with a body length of 2-4cm to grow to 1 jin, while it usually takes about 5-8 months for fry with a body length of 3-5cm to grow to 1 jin. However, due to differences in breeding technology, breeding environment and other factors, the specific time required for tilapia to grow from fry to 1 jin should be determined according to actual conditions.

2. Breeding methods

(1) Build the breeding pond in a place with convenient drainage, no pollution sources and sunshine. The water depth is generally 1.8-2.5cm and it is equipped with an aerator.

(2) Before stocking, the pond should be cleaned and disinfected, and an appropriate amount of fertilizer should be added to cultivate plankton.

(3) When the water temperature rises above 18°C, fish fry can be released.

(4) The feed should generally be mainly protein feed, supplemented by green feed, and fed once in the morning and afternoon each day.

Which type of tilapia is good?

1. Oni Tilapia

(1) The Aurelian tilapia has a relatively small head, a relatively high back, and a relatively thick body. It is a hybrid of the Aurelian tilapia and the Nile tilapia.

(2) Onyx tilapia can live in both fresh water and brackish water. The optimal temperature for its growth is 24-35°C. It is also resistant to low oxygen and can usually grow normally in fertile water with relatively low dissolved oxygen content.

2. GIF Tilapia

(1) Compared with other tilapia species, GIFT tilapia grows 5-30% faster, is easy to domesticate, has a high meat yield, and is more cold-resistant and adaptable to the environment.

(2) GIFT tilapia has a relatively high salt tolerance and is suitable for breeding in an environment with a salinity of 0-12‰. However, it is not suitable for breeding when the salinity is 32‰.

3. Red Tilapia

(1) Red tilapia is a mutant hybrid of Nile tilapia and Mosambique tilapia. It has a red body color, no black membrane in the body cavity, tender meat, and is characterized by fast growth and high yield.

(2) Red tilapia is a tropical euryhaline fish that is relatively resistant to low oxygen and has a suitable growth temperature of 15-38°C. It is an omnivorous and plant-based fish. In nature, it mainly feeds on phytoplankton. In artificial breeding, it can eat rice bran, corn meal, fish meal, compound feed and other foods.

4. Jili Tilapia

(1) The body color of the Jili tilapia is grayish white, the color of the back is orange or golden yellow, and the color of the side of the abdomen is pearl blue. It is a new salt-tolerant variety suitable for commercial marine aquaculture.

(2) Tilapia can usually live in both seawater and freshwater and is an omnivorous fish.

5. Nile tilapia

(1) Nile tilapia is a euryhaline fish with a relatively strong tolerance to low oxygen. However, in order to ensure its normal growth, the dissolved oxygen content in the water should generally be kept above 3 mg/L.

(2) Nile tilapia usually lives at the bottom of the water body, but it will move to other water layers as the water temperature changes. For example, it will swim to the middle and upper layers in the morning, move to the area close to the water surface at noon, move to the middle and lower layers at night, and stay still at the bottom of the water at midnight and dawn.
