Problems solved by technology

[0002] Freshwater shrimp is also known as river shrimp. The cultivation technology of freshwater shrimp belongs to relatively mature artificial aquaculture technology, especially the pond culture of freshwater shrimp is the most. The freshwater shrimp is tender in quality, delicious in taste, rich in nutrition, and has medicinal value. It is favored by people. Freshwater shrimps live widely in lakes and ditches. They like to inhabit shallow waters. They are omnivorous animals. The larvae are mainly plankton. Farming output is based on pond farming. In order to improve the utilization rate of ponds and farming benefits, polyculture will be considered during breeding. There are existing examples of polyculture of...

Abstract

The invention belongs to the technical field of agricultural culture, and particularly relates to a freshwater shrimp and tortoise polyculture method. A culture pond is 1.5m in depth, a plurality of movable reversed-A-shaped nets are arranged in a polyculture pond, and Sibin Bian-stones are arranged in sealed parts in the reversed-A-shaped nets. Compared with the prior art, the freshwater shrimp and tortoise polyculture method has the following advantages: with the adoption of the reversed-A-shaped nets, tortoises are limited within a certain growth area, while freshwater shrimps can shuttle in multiple areas, in this way, the freshwater shrimps can be prevented from being caught and eaten by the tortoises and can also drive the tortoises to move to be lively; in corresponding stages, appropriate amounts of young shrimps and young tortoises are thrown into the culture pond, respective growth areas are rationalized, and the shrimps and the tortoises can grow in the respective growth areas healthily; and the freshwater shrimps can eat residual feeds of the tortoises, so that the water quality is adjusted effectively, the pond space is used effectively, and the economic benefits of tortoise and freshwater shrimp culture are raised.

Example Embodiment

[0023] Example 1
[0024] Such as Figure 1-2 As shown in the figure, for breeding in a breeding farm in Anhui, a pond of about 2 acres is selected. The width of the breeding pond is about 25 meters and the length is about 53 meters. The width of the inverted A net is set to 25 meters. When the A-type net is in the open state, the span on both sides of the top is 16m, and the distance between the adjacent sides is 1.5m. Three inverted A-type nets are set in the pond, and the fixed sides of the inverted A-type nets on both sides and the pond side The distance is 1m;
[0025] A breeding method for polyculture of green prawns and tortoises. The depth of the breeding pond is 1.5m. A number of movable inverted A-type nets are set in the polyculture pond, and the sealed part of the inverted A-type net structure is equipped with Sibin Bianstone;
[0026] (1) In mid-May, the initial state of the inverted A-type net was set up with two overlapping nets in the vertical direction. Shrimp seedlings were put into the pond at a density of 50,000 fish/mu, and mixed pellet bait A was fed;
[0027] The protein content of the mixed granular food A is 15-18%, and the raw material contains 13.5% of the total weight of the raw material.
[0028] (2) In the first ten days of June, the inverted A-type net was in an open state to form an inverted A-type net structure. The tortoise seedlings were placed in the platform structure above the tortoise seedlings at a density of 200 per acre. The mixed pellet bait B was fed every time. Adjust the water quality with a water quality regulator every 6 days;
[0029] The protein content of the mixed granular bait A is 18-20%, and the raw material contains 16.5% of the total weight of the raw material.
[0030] The water quality regulator is prepared from the following parts by weight of raw materials: potassium iodide 18-24, squid paste 16-20, papain 8-12, polyepoxysuccinic acid 8-12, povidone iodine 8-12, seaweed Extract 10-15, puerarin 5-8, D-isoascorbic acid 7-10, dextran 15-22;
[0031] (3) Catch the blue prawns in early October, remove the inverted A-type net, feed the mixed pellet feed C, and adjust the water quality with the water quality regulator A;
[0032] The protein content of the mixed pellet C is 25-28%, and the raw material contains solanum grass equivalent to 18% of the total weight of the raw material;
[0033] (4) To catch turtles in late October, and clean or repair ponds and inverted A-type nets.
[0034] Wherein, the mesh of the inverted A-type net can allow shrimp seedlings to pass through, but not turtle seedlings.
[0035] Wherein, the body length of the shrimp larvae is 1 cm, and the body length of the tortoise larvae is 200-250 g; during fishing, the body length of the shrimp larvae is about 4 cm, and the size of the tortoise is about 680 g.
[0036] Using the method of the present invention, the average feed coefficient of the tortoise is 1.52, the survival rate is 95.8%, the average feed coefficient of the blue shrimp is 1.76, the survival rate reaches 96.4%, the survival rate and the feed coefficient both reach a high level, and the economic benefits are significant.
