Circulating water high-density fish culture device and method thereof

Abstract

The invention provides a circulating water high-density fish culture device and a fish culture method thereof. The circulating water high-density fish culture device comprises a culture pond, a pressurizing and oxygenating device, an oxygen source and a plurality of purifying and filtering devices, wherein the pressurizing and oxygenating device and the oxygen source are both connected with the culture pond, the culture pond is connected to the first purifying and filtering device, the last purifying and filtering device is connected with the pressurizing and oxygenating device, sewage in theculture pond is discharged into the first purifying and filtering device, the sewage is subjected to multiple purification and filtration through the sewage filter of each purifying and filtering device to form culture water, and the culture water is supplemented to the culture pond through the pressurizing and oxygenating device, so that the water level of the culture pond is always kept at a setwater level. The circulating water high-density fish culture device has the function of simultaneously achieving oxygenation in two modes, the oxygenation problem under different conditions is solved, the characteristic of high-density circulating water is achieved, and the circulating water high-density fish culture device can be suitable for fresh water and seawater fish culture environments.

Description

technical field [0001] The invention relates to the technical field of fishery water treatment equipment, in particular to a circulating water high-density fish farming device and a method thereof. Background technique [0002] The development of intensive high-density farming technology will play an important role in the future aquaculture industry. There is great potential to develop high-density freshwater fish farming by utilizing lakes, reservoirs and river ditches. Suitable freshwater fish farming methods include cage fish farming, pen fish farming and running water fish farming.
