Rice field ecological planting and breeding method

The invention relates to a rice field ecological planting and breeding method. By means of the rice field ecological planting and breeding method, Procambarus clarkii are bred and rice is planted in a rice field circularly. The rice field ecological planting and breeding method includes the steps of preparation of the rice field, putting of shrimp seeds, feeding of shrimps, rice cultivation, management of the rice field, fishing for shrimps and reservation of parent shrimp seeds. Circular grooves of the rice filed are disinfected and grass is planted in the circular grooves immediately after the circular grooves of the rice field are finished, the reservation of parent shrimp seeds is mainly carried out in the later period of finishing, and parent shrimps are guaranteed to be reserved in the field for breeding parent shrimps of the next year. The rice field ecological planting and breeding method has the advantages that the Procambarus clarkii are reserved after rice is harvested, and the rice field does not need to be turned over, ploughed or harrowed, planting and breeding are jointly carried out continuously and the utilization rate of farmlands is high; fertility of the farmlands is uniform; worm eggs are eaten by the shrimps so that diseases and insect pests of the rice can be prevented; the survival and breeding environment of the shrimps is stable, and the yield is high; the structure of the rice field is favorable for breeding and growth of the shrimps; chemical inorganic fertilizer and chemical pesticides are not used, so that the natural ecological environment is effectively protected.

Breeding method and pond for improving commercial specification and yield of procambarus clarkii in pond

The invention provides a breeding method and a pond for improving the commercial specification and the yield of procambarus clarkii in the pond. The breeding method comprises the following steps: drying the pond under the sun; putting young procambarus clarkii into the pond for the first time; performing catch rotation on commercial procambarus clarkii for the first time; putting young procambarus clarkii into the pond for the second time; performing catch rotation on commercial procambarus clarkii for the second time; and thoroughly draining water of the pond, and catching all commercial procambarus clarkii. The pond comprises a circular groove which is digged along the periphery of the pond, wherein the circular groove has an upper bottom width of 6 to 10 meters, a lower bottom width of 1 to 5 meters, a depth of 0.8 to 1 meter, a ridge height of 0.8 to 1 meter and a slope ratio of 1: 3; the area of the circular groove accounts for 20 to 30% of the total area of the pond; the a region, located at the inner side of the circular groove, of the pond is piled with a central enclosed beach; and the distance between the water level of the pond and the central enclosed beach is in a range of 10 to 70 cm. The invention has the following beneficial technical effects: by adopting the method provided by the invention, 200 to 250 kg of commercial procambarus clarkii can be harvested in two seasons, wherein the proportion of the commercial procambarus clarkii with a specification of 40 g or more reaches 60 to 70%.

Procambrus clarkii indoor artificial propagation method

The invention provides a procambrus clarkii indoor artificial propagation method, belonging to the freshwater shrimp breeding technical field. The method includes the following steps: 1) sorting and group matching of parent procambrus clarkii; 2) temporary culture of the parent procambrus clarkii; 3) induction concentrated synchronous oviposition; 4) artificial incubation and sorting of spawning procambrus clarkii; 5) cultivation of young procambrus clarkii. The procambrus clarkii indoor artificial propagation method ensures that procambrus clarkii can be successfully propagated indoors by artificially regulating the propagation condition of procambrus clarkii. The method is simple and has strong feasibility, the spawning rate thereof reaches 84%, fertility rate reaches 90%, hatching rate reaches 86%, survival rate reaches more than 80%, the situation that procambrus clarkii postlarvae can be obtained only by natural propagation under the existing condition is changed, the problem that procambrus clarkii postlarvae is scare is solved, and stable and batch postlarvae production capacity is formed. Meanwhile female procambrus clarkiis synchronously lay eggs in a relative concentrated way while natural propagation is in droves and postlarvae can not be quantitatively obtained in time; postlarvae stocking can be carried out ahead of time; and postlarvae specification is relatively uniform.
