1. Pond culture

(1) Pond conditions: red tilapia, like other tilapia, does not have high requirements for ponds. Generally to 5 acres or less is good, mainly to facilitate the management and catch. Pool depth of 2 meters, water depth of 1.5 ~ ~ 1.8 meters or so. Water quality is good, can change, water injection. Seedlings should be cleaned and disinfected, fertilized to fertilize the water quality before placement.

(2) fish stocking: according to the mu total output of 500 to 600 kilograms of requirements, the main stocking density, per mu can be 3000 ~ ~ 4000 tails of summer flowers, or put the overwintering fish 10 ~ ~ 20 grams of overwintering fish species 1500 ~ 1800 tails. The former fall tail weight up to 150 ~ ~ 200 grams, the latter should be about 400 grams, to enlarge some of the fish species is good. Another with carp, crucian carp, silver carp, bighead carp and other species 200 to 300 tails. Mixed stocking density, with "four big fish" as the main, mixed with 5 to 50 grams of wintering red tilapia species 200 to 500 tails. In the fall, the specification is 250-500 grams. Fish species should be placed in the water temperature stabilized at 18 ℃ above.

(3) feeding management: feeding pre-species of small size, like group swimming feeding, should pay attention to the appropriate feeding of high nutritive value of concentrate feed, to promote the rapid growth of fish species. Due to the high density of fish, bait fertilization, easy to appear floating head, to diligently change the water, refill new water, such as equipped with an oxygenator, should be turned on at the right time to increase oxygen. Late breeding, that is, August to September, some of the fish have reached the market specification, should be timely fishing, one can use the fishing season to enter the market, improve the selling price, and the second is to reduce the density of fish in the pool, grasp the late management, improve the specification.

2. net box culture

(1) set the water conditions: general water quality is fresh, open water, water depth of more than 2 meters, non-polluting small lakes, reservoirs, rivers and ponds can be set up in the net box to have a slight flow of water in the place of the best, the requirements of the bottom of the box from the bottom of the water 30 to 50 centimeters.

(2) net box specifications and setup: breeding red tilapia net box to be smaller, 10 to 30 square meters for more, it is best to develop 1 to 4 cubic meters of small net box breeding red tilapia, setup and management are convenient. There should be a spacing of 3 to 5 meters between two nets, and the arrangement of nets should be perpendicular to the direction of water flow, and there should also be a distance of more than 10 meters between two columns.

(3) put density and specifications: the traditional net box is generally dozens of square meters, each square meter of fish species dozens of tails. In recent years, the promotion of small net box, according to different water conditions and management level, each cubic meter can be put 200 to 600 fish species. Species specifications to be larger for the better, the small net box requires species specifications in 50 grams / tail or so, October listing tail weight in 400 to 500 grams.

(4) feeding management: in the water quality of thin transparency of the waters, net box culture to feed the main pellet feed. The feed should be nutritionally comprehensive, requiring feed protein content of 28% ~ ~ 32%, crude fat 5% or so, in addition to adding a certain amount of vitamins and minerals. Feeding 2 to 3 times a day, according to different water temperatures and different developmental stages of the fish body, the daily feeding amount of 2% to 5% of the weight of the fish.
