Rice field fish culture method

Abstract

The invention discloses a rice field fish culture method, and belongs to the technical field of aquatic product culture. The rice field fish culture method comprises the steps of rice field selection,fish ditch excavation, water inlet and drainage system construction, heightening, widening and tamping of ridges, fish grass planting on the ridges, fish fry putting, feeding, rice field fertilization and management. According to the method, land resources are sufficiently and reasonably used, production management is scientific, and the method has the characteristics of high grass carp survivalrate, low morbidity, high yield and good quality; and grass carps take tender grass in a rice field, fish grass on the ridges, rice foot leaves, duckweeds and insects as main food, so that green and ecological breeding is achieved, meanwhile, the manual weeding cost is saved, the light transmission between rice is enhanced, diseases and insect pests of the grass carps and the rice are reduced, theecological environment of the rice field is effectively improved, and finally the obtained grass carps are ecological rice field grass carps which are tender and compact in meat quality, free of fishy smell, strong and slender in body shape and yellow in fish scale.

Description

technical field [0001] The invention relates to the technical field of raising aquatic products, in particular to a method for raising fish in paddy fields. Background technique [0002] Traditional paddy field fish farming methods either simply use paddy fields instead of fish ponds for primitive stocking without scientific management, or dig shallow ditches or water dams in paddy fields, both of which are difficult to breed in paddy fields Grass carp achieves a double harvest of fish and rice, and the fish species are relatively single, mainly carp and crucian carp. Fish must be raised when rice is harvested. The growth time of fish is short and the comprehensive economic benefits are low; Optimizing the ecological environment while improving the land use rate, scientifically and rationally growing in rice fields, high survival rate, low disease incidence, high yield, high economic benefits, tender and firm meat without fishy smell, strong and slender body, yellow scales ...
