Breeding method of crucian carps

Abstract

The invention discloses a breeding method of crucian carps. The breeding method comprises the following steps: (1) excavating a fish pond, wherein one or more terraces with certain slopes are arranged in the fish pond, and water plants are planted on the terraces; (2) breeding fry, wherein 30-50 fry are stocked in each square metre, sufficient fry are put once, tidy specification of fishes out of the pond each time can be guaranteed, and intensive breeding and selling are facilitated; when the water temperature is stabilized to 10 DEG C or above, crucian carp fry can be stocked, wherein the crucian carp fry account for 80%, and carps, grass carps and silver carps totally account for 20%; (3) raising the fry. According to the breeding method disclosed by the invention, the crucian carps have a good living place and a clean water flow in the fish pond, the fry are scientifically fed with a green feed, so that the fry can play in the water, the moving amount of the fry is improved, the constitutions of the fry are strengthened, the ingestion capacity of the fry is improved, the diseases of the fry are reduced, and the rapid growth of the fry is promoted.

Description

technical field [0001] The invention belongs to the technical field of cultivation of fish, mussels, clams, lobsters, sponges, pearls, etc., and in particular relates to a method for cultivating crucian carp. Background technique [0002] In the breeding process of aquatic products such as fish, they usually rely on natural water resources by rivers, lakes or coasts for stocking. This method of farming is low in cost, but in the event of natural disasters, river pollution, storms or sudden changes in weather, It will cause fish to die or run away on a large scale, resulting in heavy losses for fish farmers. There is another method of breeding and stocking fish by digging ponds. By adding artificial feeding bait, the rapid growth of fry can be promoted. This kind of stocking The grown fingerlings have low nutrient content, poor taste, and low economic value. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a method for ...
