The experimental ponds in Wuhan mainly raise mackerel, and the effect is very good. The method is as follows: 1220 overwintering bream species with a tail weight of 40 grams per mu, 200 silver carp species with a tail weight of 50 grams, 30 silver carp fingerlings with a tail weight of 60 grams, and some high-backed crucian carp fingerness. the feed element number is 1.8 and the feed is scattered evenly by hand. Pay attention to water quality management at ordinary times to prevent water quality from deteriorating and flooding ponds, and the dissolved oxygen in the pond water is not less than 2 mg / L day and night.
