Abstract

The invention relates to a rice and freshwater grouper symbiotic culture method. The method comprises the steps that a certain rice field is selected, ridge integration is conducted, ditches with a certain gradient are dug, cobblestones are laid, and disinfection is conducted; base fertilizer is scattered, deep ploughing is conducted, and water diversion and field cultivation are conducted; rice seedlings are planted, and foliar fertilizer is sprayed; freshwater grouper fries are put into traditional Chinese medicine liquid which is prepared by adding water into honeysuckle, houttuynia cordata and coptis chinensis and then conducting boiling together for medicated bath; when new seedling leaves grow from the rice seedlings, the freshwater grouper fries are put; water in the rice field is flowing water, and the water level is controlled to be deepened by 5 cm in the flowering and grain filling stages of rice; and the traditional Chinese medicine liquid which is prepared by adding the water into the honeysuckle, the houttuynia cordata and the coptis chinensis and then conducting boiling together into the flowing water at regular intervals to prevent and treat plant diseases and insect pests. According to the method, the freshwater groupers and the rice are subjected to symbiotic culture, the freshwater groupers which are delicious in meat quality and comparable to wild freshwater groupers in body form can be produced, the utilization efficiency of the rice field can be improved, and the method has good economic value and social benefits.

Description

technical field [0001] The invention relates to the technical field of fish culture, in particular to a symbiotic culture method for rice and freshwater grouper. Background technique [0002] The freshwater grouper is spincup-shaped with upper mouth; there are eight black stripes on both sides of the body, and there is a darker pigment block in the center of the vertical black stripes; the pectoral fins are light yellow, the pelvic fins, dorsal fins, and anal fins have black stripes, and the caudal fin is black The stripes are perpendicular to the body; except for the black and white stripes, the body surface of the adult fish is slightly yellow, and the body color changes adaptively with the external water environment and the reproductive period; when breeding, the body color of the male fish is darker, and the body color of the female fish is lighter , with yellow, pelvic fin pectoral, caudal fin round tail, with genital process; juvenile fish eye orbit is red, adult fish ...
