Abstract

The invention discloses a breeding method of crawfishes. The method comprises the following steps of selection of a breeding pond; disinfection treatment; water culture; aquatic plant transplantation;shrimp seed putting, wherein 1-3 days before shrimp seed putting, duckweed is put according to the amount of 40-50 kg / mu at first, and spiral shells are put according to the quantity of 50-100 kg / mu;then the shrimp seeds are put according to the density of 100-120 thousand / mu; feed putting, wherein crawfish feed is used as breeding feed, the putting amount of feed every day is 10-20% of the total quantity of the crawfishes, and feed putting is conducted three times in the morning, in the afternoon and in the evening; in the breeding process, traditional Chinese medicine decoction is put onceevery month, and the putting amount is 10-20 kg / mu, wherein the traditional Chinese medicine decoction is formed in the mode that radix astragali, radix codcnopsitis pilosulas, rhizoma atractylodis,grifola and liquorice are matched according to a specific proportion and water is added to the mixture for decoction. According to the breeding method of the crawfishes, the survival rate of the crawfishes can be effectively increased.
