Freshwater Vannamei shrimp farming

Freshwater culture of Vannamei Shrimp update 21 June 2017

One of our team members Mr Fabio is currently doing an consultancy job for freshwater Vannamei shrimp farming in Brazil.

The small 27ha farm has open outdoor 3ha ponds and in remodeling for intensive greenhouse and linned ponds. All outdoors ponds are stopped due WSSV outbreak and I'll start over with new preparation procedures. The new set-up has a nursery, pre-growout and growout ponds. All of them with greenhouse and hdpe bottom cover. In this farm we will practice freshwater culture super intensive for vannamei.
