An artificial breeding pond for reducing the occurrence of digestive tract diseases in loach

Abstract

The invention provides an artificial breeding pond capable of reducing incidence of digestive tract diseases of loach and relates to the aquaculture field. The slope-protected pond has the area of 2000m<2> to 3000m<2>, is rectangular in the length-width ratio of 2: 1 or 3: 2, and 80cm-150cm deep; the thickness of sludge at the bottom of the pond is not more than 30cm; the bottom of the pond is inclined towards a drain outlet and provided with a fish pit connected with the drain outlet; the area of the fish pit is 5% of that of the bottom of the pond; the fish pit is 30cm lower than the bottom of the pond; a water inlet is formed 20cm under the surface of the bank of the pond; the surface of the bank of the pond is 150cm wide; the water inlet is formed form a pvc (polyvinyl chloride) pipe and has the diameter of 30cm to 40cm, and a filter screen formed by use of fine-mesh cloth for intercepting harmful organisms is mounted at the orifice of the pipe; the drain outlet is in the bottom of the fish pit at the bottom of the pond diagonally opposite to the water inlet; the drain outlet is provided with a sluice valve against the bank of the pond and also an anti-escape net. A medicine soil layer is paved in the artificial breeding pond capable of reducing the incidence of digestive tract diseases of the loach; a traditional Chinese medicine composition blended with the medicine soil layer can be slowly released into water to prevent and treat digestive tract diseases of loach seedlings and reduce the incidence of digestive tract diseases; the medicine soil layer is blended with clay, and after the medicine soil layer contacts with water, the medicine is slowly released, and the clay is capable of controlling slow release of the medicine.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an artificial culture pond for reducing digestive tract diseases of 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 ...

Problems solved by technology

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 utilization rate of feed 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 restricts the growth rate of loach. Healthy development of aquaculture

In the prior art, for the cultivation of loach seedlings, there is a problem of high mortality of loach seedlings, and digestive tract diseases are one of the main factors for the death or slow growth of loach seedlings
