Problems solved by technology

In this work arrangement, farmers often experience: reduced oxygen concentration, which is insufficient for fish and / or shrimp; increased energy consumption and costs due to lower efficiency in harsh conditions; Increased risk of fish hypoxia due to malfunction; uneven oxygen distribution and water circulation due to fixed positioning and distribution of aerators, species of fish, pond shape and volume, and limited water flow in the pond; Problems associated with vertical water stratification and variable oxygen concentrations caused by photosynthesis and uneven fish distribution; reduced water exchange; and accumulation of organic solids (feces and feed residues) on the bottom of ponds when not drained efficiently and in a timely manner

Abstract

The invention provides a device for oxygenating a water body. The device comprises a Venturi tube supported along a path of the water body, a pump for conveying water to the Venturi tube and a dividedmanifold which is communicated with fluid in the Venturi tube and extends into the water body, wherein the Venturi tube receives pure oxygen mixed with water from the water body and is used for supplying an oxygenating mixture; the divided manifold is used for conveying the oxygenating mixture as propulsion into the water body. The invention further provides a related method.

Description

technical field [0001] This embodiment relates to a device and method for oxygenation of fish farms and ponds which may be located indoors or outdoors. Background technique [0002] Known aquaculture includes fish and / or shrimp farming in shallow ponds, eg in Asia and other countries. During this culture period, a lack of oxygen and solid waste accumulation will occur in the pond, both of which are key factors that can adversely affect the growth and health of the animals. [0003] Aquaculture farmers are known to use propeller wheel aerators, water wheel aerators, so-called paddle wheel aerators or blowers to add oxygen to pond water and to move, drive or circulate the water to remove solid waste therefrom. For example, it is known that for white shrimp (or tropical seawater fish), the suitable temperature of the water in the pond is in the range of 25°C to 30°C, wherein the salinity of the water is at a mass fraction of 5‰ to 35‰ per weight of pond water within range.
