Method for comprehensive cultivation of procambarus clarkii in paddy field

Abstract

The invention discloses a method for comprehensive cultivation of procambarus clarkii in a paddy field, which includes paddy field selecting, paddy field planning, young procambarus clarkia putting-in, feeding management, daily management, adult procambarus clarkia catching, juvenile procambarus clarkia putting-in, parent procambarus clarkia retaining and rice planting. Waste discs are hung in theannular ditches dug in the paddy field and in the 'cross'-shaped or groined field ditches in the middle to drive away water birds, so that water birds are prevented from preying on procambarus clarkia and damaging rice panicles. In addition, the excrement of procambarus clarkia provides high-quality fertilizer for the growth of rice. Therefore, the ecological environment of the paddy field is improved, and the rice yield is increased. Moreover, the procambarus clarkia seldom gets ill because of the sufficient dissolved oxygen in the water in the paddy field, which is conducive to greater economic benefits. The reasonable design and application of the annular ditches and the field ditches brings convenience to feeding and catching. The planting of rice will not be affected. Good harvest isachieved for both rice and procambarus clarkii.

Description

technical field [0001] The invention relates to a method for cultivating crayfish, in particular to a comprehensive method for cultivating crayfish in paddy fields. Background technique [0002] The scientific name of freshwater crayfish is Procambarus clarkii, referred to as crayfish, and it is a species of freshwater crayfish. Crayfish belong to the phylum Arthropoda, Crustacea, Decapod, Pseudoclawidae, and the genus Slippery Crayfish in taxonomy. From the structural point of view, there are no obvious spines on the body surface of crayfish. There are 13 somites in the head and chest, and 7 somites in the abdomen. The body surface is covered with chitin carapace. That is the first pair of walking legs, the other 4 pairs of walking legs are not as strong as the first pair, 1 pair of large antennae, 2 pairs of small antennae, 4 pairs of swimming legs in the abdomen, born in the 2nd to 5th abdominal segments, tail and The tail leg of the sixth abdominal segment develops into...

Problems solved by technology

[0003] According to the characteristics of the appeal, crayfish is one of the rare economic shrimp species in the world. It belongs to tropical animals. It is impossible to reproduce and hatch in the environment. In addition, due to the sharp increase in market demand in recent years, the natural resources of crayfish have decreased sharply and the price has gradually increased. Therefore, artificial scientific breeding is required to meet market demand. In order to consider economic benefits, although The scale and area of ​​paddy field comprehensive breeding are rapidly increased, but the rice paddy cultivation method and model are improper, and the lobsters are relatively scattered, so it is not convenient to catch lobsters, and it is also prone to crayfish escape and predator predation. The survival rate and output of crayfish are affected, and farmers cannot be guaranteed to obtain corresponding economic benefits
