Green breeding method for fishes in paddy field

Abstract

The invention discloses a green breeding method for fishes in a paddy field. The method comprises the following steps: (1) selecting a paddy field and conducting earlier-stage treatment: selecting a paddy field which is convenient for irrigation and has hard ridges, and arranging a water inlet and a water outlet; (2) throwing in fry: introducing a fresh water source again into the paddy field when rice plants in the paddy field grow to 20-30cm; and (3) conducting breeding management: breeding lemna minor in the paddy field, wherein the lemna minor breeding area is 30-40% of the paddy field area, and throwing in granular fodder to the paddy field twice every day. According to the above steps, the breeding method accelerates the fish growth speed in the paddy field through reasonable arrangement of processes such as selecting the rice field, conducting earlier-stage treatment, throwing in the fry and conducting breeding management, and no any hormones or additives are added in the whole breeding process, so that bred fishes are green and healthy, and the edible value is high.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a green breeding method for fish in paddy fields. Background technique [0002] In order to improve the utilization rate of land resources, more and more people are cultivating fish in paddy fields while planting rice. However, in order to pursue economic benefits, some farmers often add some hormones to paddy fields during the breeding process to promote The rapid growth of fish makes a large amount of hormones remain in the body of the fish after it grows up, and its edible value is low. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a green breeding method for fish in paddy fields with fast fish growth and high edible value. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a green breeding method for fish in rice fields, co...
