1. Equipped with oxygenation facilities. According to the principle of 1 aerator per 5 mu, aeration facilities are equipped to ensure that under high-density breeding conditions, the tilapia cultured will not have floating heads. Ensure high and stable production.
2. feeding. In the breeding process, in order to save costs and also comply with the principle of pollution-free, before the tilapia reaches 150 grams, use fertile water to cultivate fish, rely on animal manure ponds to cultivate biological feed to raise fish, under normal circumstances, fertilize once a week, 100 to 150 kg per mu each time. After 2 to 3 months, after the tilapia raised reaches the size of 250 grams per tail, enter the medium-term breeding, change the breeding method, and put in the full price to match the tilapia feed for breeding. At this time, the theoretical feeding principle is Adhere to the "four fixed" feeding, in general, feed twice a day, 9 to 10 am and 5 to 6 pm each day. When the daily feeding amount is 3% to 4% of the fish weight, adding 0.75 to 1 kg of Yinxiang brand tilapia feed can produce 0.5 kg of adult fish. In fact, when many farmers put in feed, as long as the fish can feed, on the principle of not wasting feed, they can feed as much as the fish can feed, and the tilapia they raise will grow faster, about 7-8 months. Can grow to more than 1 kg/tail. In the middle and late stages, it is necessary to keep the water quality fresh and ensure that the fish have a good appetite to achieve rapid growth.
