Dr Eckel – Germany’s pioneer in functional feed additives – is constantly working on new solutions to provide reliable solutions for premium aquaculture feed. Dr Eckel now releases Anta®Ox Aqua – the all-natural feed additive for intensive Shrimp production.

Shrimp farmers from around the world have the same goal to keep their production system in a balance. Endemic pathogens and epidemic diseases (like EMS/AHPN caused by Vibrio parahaemolyticus) constantly put this balance at risk.

In the past it was commonplace to keep farming system in balance by the preventive use of antibiotics. Customers and retailers in Europe, the US and other markets become more and more sensitive to the abundance of antibiotic drugs usage in animal production. Hence, shrimp farmers need alternative tools to keep their animals healthy.

Functional feed additives are alternative way to strengthen the natural defence mechanism of the animals and therefore to keep the production system in balance. The farmer recognizes this by high growth rates, good feed conversion and low mortalities.

Lab results reconfirmed in large-scale field trials
Anta®Ox Aqua can directly decrease the bacterial infection and increase the survival rate of Pacific White Shrimp. This was confirmed in feeding trial in the lab as well as in the pond. Trials conducted in cooperation with the renowned Kasetsart University in Thailand gave spectacular results under laboratory conditions. The protective and immune-stimulating effects of Anta®Ox Aqua at the cellular level were measured and visualized (Niyamosatha et al. 2015).

In follow-up pond trials conducted under supervision of Kasetsart University of Bangkok these results have now been confirmed under commercial farming conditions in South-East Asia. Anta®Ox Aqua significantly reduced the number of Vibrio bacteria in the hepatopancreas (Fig 1). EMS is known to cause necrotic cells in the hepatopancreas of shrimp.
