A pond for artificially breeding loach

Abstract

The invention discloses a pond for artificially culturing misgurnus anguillicaudatus, and relates to the field of aquaculture. The slope-protected pond is 2,000-3,000 square meters in area and is rectangular, the length-width ratio is 2:1 or 3:2, the pond depth is 80-150 centimeters, and the thickness of sludge at the bottom of the pond does not surpass 30 centimeters; the bottom of the pond inclines towards a water outlet, a fish pit connected with the water outlet is arranged, is 5 percent the area of the bottom of the pond and is 30 centimeters lower than the bottom of the pond; a water inlet is formed 20 centimeters below the bank surface of a pond bank, and the bank surface of the pond bank is 150 centimeters in width; the water inlet is made of a PVC (Polyvinyl Chloride) pipe, and is 30-40 centimeters in diameter; a filter screen which is made of dense screen cloth and is used for intercepting pests is arranged on a pipe orifice; the water outlet is formed in the bottom of the fish pit at the bottom of the fish pond obliquely opposite to the water inlet; a gate valve is arranged at the water outlet close to the pond bank; an escape-proof net is arranged. In the pond for artificially culturing misgurnus anguillicaudatus provided by the invention, a medicinal soil layer is paved, and a blended Chinese medicinal composition can be used for inhibiting and killing major pathogenic bacteria of misgurnus anguillicaudatus and has good prevention and control effects on bacterial diseases of misgurnus anguillicaudatus; the medicinal soil layer and clay are blended, the pesticide effect can be released out slowly after contact with water, and the clay has the effect of controlling the release of the pesticide effect.

Description

technical field

[0001] The invention relates to the field of aquaculture, in particular to a pond for artificially cultivating loach. Background technique

[0002] Loach (Misgurnus anguillicaudatus) has high nutritional and medicinal value. It has a large demand in the domestic and foreign markets, and the price is relatively good. The artificial breeding has high profits and quick results, and the breeding prospect is promising. The breeding area of ​​loach in China is 15 million to 20 million square meters, mainly concentrated in Jiangsu, Henan, Hubei, Shandong, Anhui and Sichuan, and the breeding mode is mainly pond seine farming with soil. At present, the main factor that restricts the efficiency of loach farming is that the growth rate of loach is slow, and the annual growth rate is difficult to reach more than 3 times; the feed utilization rate is extremely low, and the bait coefficient is generally between 4.0 and 6.0, and some even as high as 8.0, which seriously res...
