Evonik and Vland develop AQUAVI to improve water quality in aquaculture

AF FEAGDeveloped by Evonik and the Qingdao Vland Biotech Group, AQUAVI ProPond is part of a system solution from Evonik Animal Nutrition for shrimp in aquaculture that can reduce the need for marine feed sources and significantly improve water quality and animal health

Evonik and the Qingdao Vland Biotech Group have developed an innovative product, AQUAVI, for improving water quality in aquaculture. It is tailored primarily to the requirements of shrimp farming in ponds

The new AQUAVI ProPond, is the result of about two years of joint development work and is to be launched in China. Vland will be responsible for production and Evonik for exclusive marketing.

It includes four components that are finely tuned to each other: AQUAVI ProPond, AQUAVI Met-Met, omega-3 fatty acids DHA and EPA from Veramaris algae oil, and AMINOShrimp.

AQUAVI ProPond consists of three strains of bacteria that effectively remove ammonia, nitrate and nitrite from the water. Ammonia arises from the excretions of the animals. It can have acute and chronic toxic effects and is therefore a critical parameter for water quality. Nitrate and nitrite are also harmful to animals in higher concentrations.

Dr Emmanuel Auer, head of the Animal Nutrition business line at Evonik, said,“Our common goal is to make global aquaculture, which we need to feed the world's growing population in a healthy way, more sustainable. Strategic partnerships will move us forward faster in doing so.”

Dr Christoph Kobler, head of RD&I for the Animal Nutrition business line at Evonik, commented, “Our new additive is suitable for improving the animals' living conditions by breaking down toxic compounds, for keeping animals healthy, and for reducing environmental impact caused by too frequent water exchanges.” 

Vland is a technology company based in Qingdao, China, specialising in enzymes, probiotics and animal health. Probiotics are already a central component of Evonik's Gut Health Solutions program. Both companies have their own bacterial strain libraries, which served as a starting point for joint work on a probiotic solution for improving water quality in shrimp farming.

AQUAVI Met-Met is a methionine product specially developed for shrimp, which makes it possible to feed these animals almost without fish meal. Veramaris algae oil provides the omega-3 fatty acids DHA and EPA necessary for healthy shrimp development, replacing fish oil in the feed. Both products thus help to protect marine fish stocks and preserve marine biodiversity.
