Biofouling Blamed for Fish Farm Failure

Biofouling Blamed for Fish Farm Failure

22-Oct-2018

Biofouling has again been recognised as one cause for failure of a fish farm at Port Stephens, NSW.

Nets on pens had not been cleaned since they were installed, leading to a large buildup of barnacles and weed causing structural problems in heavy seas.

“The condition of the pens in terms of excessive biofouling on both predator and inner nets would have contributed significantly to the weight of the overall fortress pen,” the interim report reads.

ClearSignal® is a clear non-toxic rubber-like coating that resists biofouling as a result of the non-stick properties of the coating itself. ClearSignal® utilizes advanced material technologies to achieve its properties and performance. The product is permanent coating that is designed to last the life of the platform or instrument it is protecting. Unlike anti-fouling systems that rely on active biocides and whose effectiveness degrades with time, ClearSignal remains 100% effective for the intended life of the instrument. ClearSignal is optically clear – compatible with optical transducers, instruments housings retain all instruments markings and identification features.
