Prawn & Shrimp Aquaculture

Helping aquaculture improve productivity and sustainability to meet the nutritional needs of a growing population.

We source more marine protein from aquaculture farms than from oceans, lakes and rivers.

 The significance of this for the sustainability of wild marine stocks is heightened by growing concern over the depletion of these stocks from over-fishing. Aquaculture farming is a rapidly growing industry that is particularly important to the nutritional needs of the developing world, but it needs to improve efficiency and sustainability.

Your challenges

As developing countries begin to adopt more sophisticated farming techniques, the downstream effects will become more pronounced. This is important across all forms of food production and, particularly, aquaculture.

Aquaculture can be an environmentally negative activity where uneaten food and waste material from the animals being farmed turns into sludge. To make this industry more sustainable, aquaculture operators need to find a way to efficiently break down these polluting sludges, as well as increase yields through lower disease and higher feed / product efficiencies.


Calix has developed AQUA-Cal+, a water conditioner that safety addresses disease and pollution, delivering improved feed performance and yield.

It has already begun to transform prawn and shrimp farming, as well as fin fish farming. As well as improving water conditions, it reduces stress on the animals and leads to increased harvest weight and survival rates, while reducing energy costs and protecting the environment.

Calix is able to offer better service, reliability and performance to its customers because it controls the entire production process from mining of raw materials, processing and production.

Calix owns and operates a mine in South Australia as well as production, testing facilities and manufacturing plants. The ability to hydrate our high surface area MgO in our patented, close-to customer facilities creates multiple benefits for our customers and local communities.

Our AS/NZS ISO 9001 certified quality system and safety, health and environmental management system are vital elements of our engineering and quality services.


Calix’s solutions are manufactured using Calix Technology, which involves grinding minerals to particles around one thousandth of a millimetre in size, and then “flash” heating them in a very short time at up to 1.000 degrees Celsius. As trapped gases in the mineral “bubble out” of the particles, we snap freeze them in a very high energy state, leaving a very porous, honey-comb-like structure.

New materials produced by Calix Technology are proving to have similar properties to highly active nano-materials, without the safety concerns and high cost, but with all the benefits. This means it has the high reactivity of nano-material, without the potential health and handling issues.

Calix has its own direct delivery, service and support capabilities and also has an established a network of local distributors and partners that can provide the best solution for your specific needs and ensure you receive excellent customer service and support.
