Embodiment

[0017] In this embodiment, taking the Hubei region as an example, the first-generation fish fry bred by crossbreeding wild crucian carp and domestic crucian carp at one age are used as cultured fry. When raising seedlings, the fish species cultivated in that year are first put into the rice fields. Before the flowers come out, the fish are stocked in separate ponds according to male and female. Once the seeds eat the grass, they will develop prematurely and will not grow up, and the fish fry produced will grow slowly. For the seedling paddy field selected, plow the rough field in early winter (the first plow is a plow, and the second plow is called a rough field), remove some lime for disinfection, and plow the rough field again at the end of winter, then pour about 1 foot of water. Loosen branches around the field for fish to spawn, and build a glyph-shaped shade shed at the same time. The length and width of the shade shed are 8 feet each, and they are 1 foot away from the w...

Abstract

The invention discloses a breeding method for a crucian carp in a paddy field. The breeding method comprises the following steps: selecting a local wild crucian carp and a domestic crucian carp, hybridizing the selected local wild crucian carp and the domestic crucian carp, putting a hybridized first-generation crucian carp into the paddy field, and breeding the first-generation crucian carp; reasonably controlling water quantity, water temperature and oxygen during breeding, putting a fry into an early paddy field, feeding the fry for two days after one week, and performing circulation until paddy is flowering, so that the fry can eat pollen dropping into water of the paddy; when in-season paddy needs draining, moving the fry into a middle-season paddy field and a later-season paddy field in order, feeding the fry for two days after one week until the paddy is flowering, and feeding is not needed after the fry eats the pollen. The kind of the crucian carp bred by the breeding method, disclosed by the invention, in the paddy field specifically eats flowers of standing grains, so that the survival rate for the breeding and the yield are high, the meat quality is good, and the economic benefit is significant.

Description

technical field [0001] The invention relates to a rice field breeding method for crucian carp, which belongs to the field of agriculture or breeding. Background technique [0002] As a method of three-dimensional agriculture, fish farming in rice fields has attracted attention. In recent years, there have been successful reports of fish farming in rice fields. But in the disclosed paddy field fish culture report, only utilize the water surface of paddy field, promptly utilize paddy field to replace pond simply, carry out original stocking in a suitable place to breed. The known paddy-fish culture method lacks scientific management, and the fry species are poor, the survival rate is low, and the yield is not high. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a paddy field breeding method for crucian carp. According to the characteristics of the paddy field itself, the method selects high-...
