Embodiment 1

[0036] A method for ecological cultivation of freshwater shrimp and cress, comprising the following steps:

[0037] (1), pond treatment

[0038] Every pond selects the common earth pond of 5 mus as breeding pond, digs into the rectangular pond that depth is 1.2m, and the pond bottom is slope surface, digs out a width along the pond width direction at the bottom of slope surface and is 3m, and depth is 0.5m. Ditch, remove excess silt at the bottom of the pond, dry the pond in mid-to-late May until the bottom of the pond turns white, hard and cracks, then inject water to 10cm, and disinfect the water in the aquaculture pond;

[0039] (2) Selection and stocking of shrimp seedlings

[0040] Before the freshwater shrimp breeding season, collect high-quality wild freshwater shrimp from the Taihu Lake water system. The body length of female shrimp is more than 5cm, and the body length of male shrimp is more than 5.5cm. They are hybridized with local freshwater shrimp to obtain shrim...

Embodiment 2

[0061] A method for ecological cultivation of freshwater shrimp and cress, comprising the following steps:

[0062] (1), pond treatment

[0063] Every pond selects the common earthen pond of 8 mus as the breeding pond, digs into the rectangular pond of 1.5m in depth, and the bottom of the pond is a slope, digs a width of 5m along the width direction of the pond at the bottom of the slope, and is 0.6m in depth. Ditch, remove excess silt at the bottom of the pond, dry the pond in mid-to-late May until the bottom of the pond turns white, hard and cracks, then inject water to 15cm, and disinfect the water in the aquaculture pond;

[0064] (2) Selection and stocking of shrimp seedlings

[0065] Before the freshwater shrimp breeding season, collect high-quality wild freshwater shrimp from the Taihu Lake water system. The body length of female shrimp is more than 5cm, and the body length of male shrimp is more than 5.5cm. They are hybridized with local freshwater shrimp to obtain sh...

Embodiment 3

[0086] A method for ecological cultivation of freshwater shrimp and cress, comprising the following steps:

[0087] (1), pond treatment

[0088] Every pond selects the common earth pond of 7 mus as breeding pond, digs into the rectangular pond that depth is 1.4m, and the pond bottom is slope surface, digs out a width along the pond width direction at the bottom of slope surface and is 4m, and depth is 0.55m. Ditch, remove excess silt at the bottom of the pond, dry the pond in mid-to-late May until the bottom of the pond turns white, hard and cracks, then inject water to 12cm, and disinfect the water in the aquaculture pond;

[0089] (2) Selection and stocking of shrimp seedlings

[0090] Before the freshwater shrimp breeding season, collect high-quality wild freshwater shrimp from the Taihu Lake water system. The body length of female shrimp is more than 5cm, and the body length of male shrimp is more than 5.5cm. They are hybridized with local freshwater shrimp to obtain shri...

Abstract

The invention discloses an ecological breeding method for freshwater shrimps and cress and a preparation method thereof, and relates to the technical field of aquaculture. The ecological breeding method comprises the following steps: (1) pond treatment; (2) shrimp larvae selection and stocking; (3) cress cultivation; (4) floating bed preparation and planting; (5) feedstuff feeding; and (6) harvesting and fishing. According to the ecological breeding method disclosed by the invention, construction and arrangement of the ecological environment of a pond are reasonably performed, so that the double-win situation of cress planting and freshwater shrimp breeding is realized, and the cress and the freshwater shrimps are promoted mutually to grow.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an ecological breeding method for freshwater shrimp and cress. Background technique [0002] In the process of conventional freshwater shrimp farming, aquatic plants such as Elodea and Hydrilla verticillium are generally used to purify pond water quality and provide places for green shrimp to avoid habitats. In addition, in the conventional breeding method, in the process of using aquatic plants such as Elodea and Hydrilla verticillium, the concentration of the water body is low due to the overgrowth of aquatic plants, the fertility in the water body is excessively absorbed by aquatic plants, or the water quality is corrupted due to the death of aquatic plants due to poor management. It has a considerable impact on the high yield of freshwater shrimp. Contents of the invention [0003] The purpose of the present invention is to provide a kind of ecological cultivation meth...
