Water quality

Mazen Elsawaf, technical director of Maher fish farm in Saudi Arabia and a strong advocate of RAS, represents a new generation of ambitious young Egyptians in aquaculture.

Aquasend’s low maintenance water quality sensors are being used by an increasingly wide range of international aquaculture producers, as CEO, Kristin Elliott, explains.

The province of Tawi-Tawi in the Philippines was once ground zero for tropical seaweed cultivation, and the industry remains its economic lifeline to this day. Five decades after its inception, however, a thorough transformation is needed.

Black soldier fly producers are being invited to trial – for free – an innovative filtration system that uses microalgae, sometimes paired with oysters, to remove phosphorous and nitrates from their waste water.

Seakura has demonstrated that seaweed farms can be used as biological filters to absorb pollutants from desalination plants and ports.

A look at both the traditional and more cutting-edge fish farming systems currently in use Hungary.

Biofilters are commonly used in recirculation aquaculture systems (RAS), but their limitations mean that innovators are busy developing possible alternatives – such as electro-oxidation – or enhancements, such as electro-coagulation and UASB reactors.

The Shrimp Tech project, a collaboration between Dutch and Vietnamese partners, aims to help Vietnam’s struggling shrimp sector compete in the global markets by promoting sustainable farming practices.

Pond farming of Gracilaria seaweeds has seen steady growth in Indonesia over the past 30 years. While demand continues to grow, both seaweed farmers and upstream processors are aware that methods need to improve, as the industry hits environmental limits.

Vietnam’s Mekong Delta is slowly being transformed by groundwater extraction, overpopulation, pollution and climate change. Unsolved, this will dramatically reduce Vietnam’s aquaculture output and pose a serious threat to local and regional food security.

Despite its lack of coastline, shrimp production has proved lucrative for a small but significant number of farmers in Punjab for nearly a decade, but many of them are now facing an uphill struggle.

While most people on Mexico’s Caribbean coast are driven to despair by the severe blooms of Sargassum that have been dumped on their beaches, Paulina Zanela is looking to find ways of putting “kelp’s ugly sister” to good use.

A project that aims to grow tilapia and vegetables in aquaponics systems that use urban waste water has recently been launched in Italy.

Elizabeth Okullow, co-founder of AquaMnara, explains how she is providing African fish farmers with innovative tools, including IoT monitoring devices and pioneering market access strategies.
