Abstract

A pond watercress planting type grass carp high-yielding breeding method comprises pond construction, pond disinfection, grass carp fingerling breeding, watercress planting, feed selection, feeding method, watercress fertilization, planting and breeding management and disease control. According to the pond watercress planting type grass carp high-yielding breeding method, a large number of feed is fed in the process of high-density grass carp breeding, the quality of the water is corrupted, the eutrophication of a water body is produced, the nitrogen, the phosphorus and the potassium in the eutrophic water body can be absorbed by the watercress, and accordingly the water body is purified and the effective development space is provided for the high-yielding breeding of the grass carp; meanwhile the watercress which is high in nutritional value is harvested and part of the watercress can provide the feed for the grass carp during harvest; the operation is simple, the management is convenient, and the economic benefits are good.

Description

technical field [0001] The invention relates to the technical field of aquaculture models, in particular to a method for planting watercress in ponds to raise high-yield grass carp. Background technique [0002] Grass carp: English name: Grass carp, commonly known as grass carp, white carp, grass carp, and mixed fish, inhabits rivers and lakes in plain areas, and generally likes to live in the middle and lower layers of water and areas with many aquatic plants near the shore. It is lively, swims quickly, and feeds in groups. It is a typical herbivorous fish. Because of its simple feeding habits, wide sources of bait, rapid growth, and high yield, it is often used as the main breeding object for pond farming and lakes, reservoirs, and rivers. Since 1958, when the technology of artificial induced spawning and fertilization and hatching was successful, the source of fry and fingerlings has been easy, and it has become the main intensive breeding target in my country, and it is...
