Australia typically uses water to benefit our benefit our aquaculture resources through the use of keeping water clean for healthy fisheries. It can be extensive depending on the level of input and output per farming area and the stocking density. Intensive aquaculture involves intervention in the growing process, such as with supplemental feeding and water aeration (such as prawn farming), whereas extensive aquaculture allows the stock to grow on its own, using natural food sources and conditions. In Cambodia inland fisheries produce between 290,000 and 430,00 tonnes of fish generating a total value of US$150-200 million. Recent studies have found that this has attributed to Cambodia’s GDP by 16% far surpassing the importance of the ‘paddy-culture’ to their GDP.
Extensive routine quantity and quality monitoring of water takes place at all Water NSW catchment. In-flow and storage areas. This constant monitoring in Warragamba Dam provides Sydney with the highest quality water possible. This monitoring also allows management staff to be able to see which areas need more assistance with identifying what areas need help and where and what is causing issues. The information recorded can also aid in the public health department’s reporting and assessing of water quality. In Cambodia bio sand water filters and household units are built to produce drinking water from contaminated sources that is clean and safe to drink. In Cambodia there are over 19,000 filters in place that work to bring clean water to over 115,000 people. To boost the system people are being educated on basic maths, reading and writing skills as well as learning how to maintain the water filters.
