Description

Pond water treatment facilities of tilapia breed usefulness

Technical Field

The utility model belongs to the technical field of tilapia breeding equipment technique and specifically relates to a pond water treatment facilities of tilapia breeding usefulness.

Background

Tilapia is a tropical fish, originally produced in Africa, and is one of the worldwide breeding varieties. Tilapia has the advantages of food impurity, fast growth, strong adaptability, less diseases, high male rate, high population yield, good meat quality and the like, and is one of excellent breeding varieties recommended by food and agriculture organizations of the United nations. The good market prospect of tilapia is the current aquaculture, especially the current domestic aquaculture breed in fresh water aquaculture.

Tilapia mossambica is used as tropical fish, in China, the main breeding places of the Tilapia mossambica are subtropical and tropical areas in the Guangdong and Hainan areas, the optimum growth temperature of the Tilapia mossambica is 15-30 ℃, and the Tilapia mossambica is bred at the temperature in the interval, so that the Tilapia mossambica can grow quickly, and the survival rate of the Tilapia mossambica; however, in the subtropical and tropical areas in Guangdong and Hainan provinces of China, the temperature is generally lower than 15 ℃ in winter, and the tilapia is easy to freeze and hurt after the temperature is lower than 15 ℃, so that farmers can lay a heat-insulating film on the surface of a fish pond to ensure that the tilapia successfully overwinter, however, in order to improve the economic benefit and reduce the breeding risk, the small farmers can breed poultry such as ducks and geese on the sides of the fish pond, the excrement of the ducks and geese is thrown into the fish pond to reduce the feed investment so as to improve the economic benefit of breeding the tilapia, however, the tilapia is only opened to digest the excrement at a proper temperature, and the tilapia is closed at a low temperature, so that the excrement is gathered in the fish pond, the fish pond water becomes turbid and even smells, so that the fish pond water is 'fat over', in the environment, the tilapia is easy to lack oxygen when the fish pond water is added at low temperature, the death rate of the tilapia is very high due to the oxygen lack in the environment, and the fish pond water is useless even if a plurality of oxygenation devices are used for supplying the fish pond. To solve the problem, the growth of tilapia can be stabilized only by desalting pond water and then preserving heat, however, a water treatment device for desalting pond water is lacked in the prior art, and a pond water treatment device for tilapia culture is provided aiming at the defect.
