Problems solved by technology

During the concentrated listing period, the fish price usually drops sharply. During the off-season of fish sales, the fish price rises steadily, causing farmers to invest a lot of seedlings when the fish price is high, and the enthusiasm for seedlings is low when the fish price is low, which affects tilapia throughout the year. Balanced supply, further leading to fluctuations in fish prices

Embodiment 1

[0035] The cultivation of embodiment 1 Aoni hybrid tilapia

[0036] a. The first farming

[0037] (1) Fingerling cultivation

[0038] In the first ten days of April, the water temperature rises to 20°C. Disinfect the first-class rough ponds and clear ponds to cultivate good water quality, and put 7-8.5 dynasties overwintering fish fry until early May, and the specifications can reach about 10-12 dynasties. At this time, the water temperature has stabilized above 20°C, and the fish species are transferred to the second-class standard rough pond that has been sterilized in clear ponds and cultivated with good water quality, and cultivated for one month to make the fish species reach about 50-100 grams;

[0039] (2) Big pond farming

[0040] In the first ten days of June, transfer the fingerlings to the grow-out ponds that have been disinfected and cultivated with good water quality. 1,800 seedlings per mu are used to match 30 bighead carp, 40 silver carp, 5 grass carp, and 3 h...

Abstract

The invention discloses a method for breeding three batches of tilapia within one year. The method comprises the steps of: setting an aquaculture pond into a primary coarse pond, a secondary coarse pond and a developing pond according to the ratio of 1 to 4 to 16 under specifications of the tilapia at different growth stages, and feeding the tilapia of which the specifications respectively are 7-8.5chao (Chinese character) (2-4cm), 10-12chao (5-15g) and 50-200g into the primary coarse pond, the secondary coarse pond and the developing pond according to the density of 40,000 per mu (unit area), 8,000 per mu and 1,800 per mu. According to the method, by two-stage coarse marking and three-stage breeding, a water body of the pond is fully utilized; the unit mu yield is greatly improved; the breeding cost is reduced; and the tilapia can be supplied in balance all the year around, and the breeding risk is reduced.

Description

technical field [0001] The invention relates to a cultivation method for raising three tilapias a year, in particular to an energy-saving and ecological cultivation method for raising three tilapias a year suitable for implementation in Guangdong and Hainan, and belongs to the technical field of aquaculture. Background technique [0002] China's annual tilapia production accounts for almost 50% of the world's annual output of 3 million tons of tilapia, which is mainly used for processing and export. In recent years, due to the impact of other species, the competition in the international tilapia market has intensified, and the export volume has been affected to a certain extent. At present, there are mainly two farming models for tilapia: one is the intensive farming model, with a single species and high breeding density, and the full-feeding model is adopted. It is difficult to improve the yield and quality, and it will also bring high risks. The second is the three-dimens...
