Fishery Aeration Services
It is generally accepted that fish suffer if the dissolved oxygen (DO) concentrations fall below about 4mg/l and have to come to the surface to breathe. Recently Aquarius Marine Group Ltd of Glastonbury reduced the size of their 'AQUAERATOR' to suit shallow fishing lakes. The patented device, with no moving parts, mixes small air bubbles with the near bed water at the base of a vertical outlet tube. The buoyant mixture of air and water is designed to rotate whilst rising up the tube, causing a great deal of turbulence, which facilitates the mixing of oxygen into oxygen deficient water.

Overview Services
Bed water is a higher density than surface water, thus successful aeration and mixing require a device on the bottom. The Aquaerator is scientifically proved to aerate and mix water bodies. It has been designed to minimise running costs, as the 'bubble plume' rises naturally to the surface, whereas many competitors are forcing air downwards, which is expensive. The new Fishery Aquaerator is successfully oxygenating bedwater at Cross Drove Fishery, Hockwold, Avalon Fishery, near Glastonbury and Bristol Water Blagdon Trout Fisheries.
Aquaerator Systems are designed for each application depending upon the size, shape and constituents in the water body. This also determines the compressed air flow rate used to feed the Aquaerators through air lines. The ecology of the bed is not disturbed as low DO bed water is removed by entering the base horizontally and its density is reduced by mixing. This expanding plume of water rises above each Aquaerator, entraining the still ambient water near the surface. The plume of over 50l/sec spreads radially over the surface releasing the air bubbles to the atmosphere.
