Aquaculture induced erosion of tropical coastlines throws coastal communities back into poverty

Shallow tropical coastlines harbour unique mangrove ecosystems, which support livelihoods and provide a natural barrier against coastal flooding. Non-sustainable land-use practices, such as large-scale clear cutting of mangroves for aquaculture, ground water withdrawal and alteration of river flows, result in rapid subsidence. The collapse of aquaculture production, due to pollution and disease, ...

Measurement of the amount of DissolvedOxygen

Dissolved Oxygen (DO) is the term used for the measurement of the amount of oxygen dissolved in a unit volume of water. In water quality applications, such as aquaculture (including fish farming) and waste water treatment, the level of DO must be kept high. For aquaculture if the DO level falls too low the fish will suffocate. In sewage treatment, bacteria decompose the solids. If the DO level is ...

Intensive Aquaculture - What Are the Benefits? - Case Study

Land-based aquaculture involves farming fish and shrimp in contained tanks or ponds by pumping in water. It is usually characterized by significant land use, high water consumption and low productivity. AquaLifeNet has developed a system of free-standing fish tanks and mini-RAS biological filters that make intensive land-based fish farming possible even in places where land and water are ...
