Embodiment Construction
[0032] A kind of ecological breeding method of river crab, freshwater shrimp, wheat ear fish high-efficiency polyculture, comprises the following steps:
[0033] (1) Pond conditions
[0034] Choose a pond with sufficient water source, fresh water quality, no pollution, convenient drainage and less silt, with an area of 10 mu and a slope ratio of 1:2.5. There is a beach in the pond, 1m deep, accounting for one-third of the pond area. The ditch is 1.8m deep, accounting for two-thirds of the pond area. The pond inlet and outlet are arranged diagonally, and the outlet is lower than the water inlet and is located at the bottom of the pond mouth;
[0035] (2) Construction of anti-escape facilities
[0036] The height of the anti-escape facility is 50cm, and the inclination angle is 15 degrees. The inner side of the wooden stick is buried in the soil 25cm, compacted and compacted, the double-layer plastic is punched with holes, and fixed on the wooden post with iron wire;

Abstract
The invention discloses an ecological breeding method for efficient polyculture of river crabs, freshwater shrimps and pseudorasbora parva. The method comprises preparing conditions of a pond, constructing escape-preventing facilities, airing and sterilizing the bottom of the pond, applying fertilizer to the pond, planting water plants, putting in snails, putting in fingerlings, regulating and controlling water quality, throwing in feed and the like. According to the ecological breeding method, the situation that siniperca chuatsi feed on freshwater shrimps in the breeding mode of shrimps, crabs and siniperca chuatsi in the past is avoided, so that the output of the freshwater shrimps is increased greatly, and the recapture rate of the freshwater shrimps is high; the pseudorasbora parva play a role as a scavenger by feeding on residual feed, so that water quality pollution is reduced greatly, water quality is improved, and the growth of river crabs, freshwater shrimps and pseudorasbora parva is boosted. According to the ecological breeding method, the output and quality of river crabs, freshwater shrimps and pseudorasbora parva are improved remarkably, death rate is lowered, feed waste is reduced, breeding cost is lowered, breeding benefit is improved, income of fishermen is increased, and efficiency improvement of the fishery industry is realized.
Description
technical field [0001] The invention relates to an ecological breeding method for highly efficient polyculture of river crabs, freshwater shrimps and wheat cods, and belongs to the technical field of aquaculture. Background technique [0002] River crabs are deeply trusted by consumers because of their delicious meat and rich nutrition, especially large-sized river crabs are in short supply in the market; due to the reduction of natural production, the production of artificial breeding is not high, which can never meet the market demand, and the price is stable at 80 yuan / kg; wheat ear fish has become more and more popular because of its delicious meat, and the market price has been rising steadily, reaching 28 yuan / kg. At present, the common shrimp, crab and fish farming models are mostly mandarin fish, and mandarin fish feed on green shrimp, which greatly reduces the production of green shrimp, making the recapture rate low, thereby reducing the breeding benefits.
