Abstract
The invention discloses a high-yield crayfish breeding method. The high-yield crayfish breeding method comprises the following steps: S1, pond preparation; S2, stocking of young shrimps: young shrimps are subjected to stocking in two batches, in the first batch, the young shrimps are bred at the end of February, the young shrimps are bred according to the specification of 100-120 young shrimps per jin and 30-50 jin per mu, and the young shrimps are harvested from March to April; in the second batch, the young shrimps are bred in the middle ten days of June according to the specification of 60-80 young shrimps per jin and 80-120 jin per mu, and the shrimps are harvested from July to December; and S3, feeding management: the young shrimps are fed with common crayfish compound feed from February to April; the young shrimps are fed with high-temperature-period crayfish compound feed from June to September; and the young shrimps are fed with common crayfish compound feed from October to December. According to the method, the crayfish breeding cycle is adjusted according to market requirements, the whole year is divided into two breeding stages for breeding large-size crayfishes, and the annual breeding benefits of the crayfishes can be effectively improved.
Description
technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-yield crayfish breeding method. Background technique [0002] Crayfish (scientific name: Procambarus clarkii) is a crustacea, decapod, and crayfish family aquatic animals, also known as Procambarus clarkii, red crayfish and freshwater crayfish. It is a freshwater economic animal and is widely welcomed by people because of its delicious meat. Crayfish has become an important economically farmed species in China in recent years. [0003] At present, the general benefit of crayfish farming is low, mainly due to the impact of the high temperature season in the second half of the year, resulting in less crayfish production in the second half of the year, and the size of shrimp is smaller. Such crayfish are low in price and low in breeding benefits; therefore, the existing Crayfish farming is mainly concentrated in the first half of the year, and it is easy to grow large-si...
