Eco friendly biofouling prevention
A replicated, controlled study in Tasmania, Australia in 1995 (Hodson et al., 2000) found that fouling organisms were less abundant and they could be more easily removed from silicon coated nets compared to untreated nets. After 163 days of immersion, there was less fouling on the white silicon coated nets (1.9 kg/m2) compared to uncoated white (7.8 kg/ m2) and black (8.5 kg/ m2) nets. Fouling organisms were also removed more easily from silicon nets compared to untreated nets; 15.3% of the fouling was removed from the silicone coated nets, but only 3.0% and 3.6% was removed from the white and black nets respectively. Three netting types were immersed adjacent to a cage of a salmon farm; a white silicon coated net (coated with Veridian 2000), uncoated white netting and uncoated black netting. Panels were placed on the nets to allow removal without disturbing the integrity of the net structure. After 140 days of immersion, nine panels (three replicates per net type) were removed to quantify ease of fouling removal and fouling composition. Panels were cleaned with a water jet held 30 cm away for 10 seconds to quantify ease of removal of fouling organisms.
