SYLLETA has developed MACROBLOCK, a potentially disruptive, cost effective and environmentally safe antifouling technology that also offers a way to control sea lice. MACROBLOCK combines foul release (slippery) and antifouling technologies to give a long lasting, easy maintenance solution to the biofouling problem. SYLLETA team hassuccessfully completed full-scale field trials of three 100-meter cage nets treated with MACROBLOCK I.
