The European prawn culture divide – reviews and monologues..

Two different grow-out culture technologies are emerging at European RAS shrimp farms.

One is clearwater and the other leans towards a microbially managed biofloc.

The water can be made clear via a variety of different methods as it can be moved towards biofloc by other methods.

Both are zero discharge RAS technology capable – as should be for EU markets and regulations.

But which is “better”? Seemingly hybrid biofloc comes out less expensive in opex.

But why?

Reduced growth to 25 g in clearwater it seems.

But why?
