Diversity of Bugulidae (Bryozoa, Cheilostomata) colonizing artificial substrates in the Madeira Archipelago (NE Atlantic Ocean)

“…Bryozoans represent a group of colonial invertebrates in benthic ecosystems and can be commonly found in fouling assemblages [66,67]. The transportation of fouling communities in ship hulls is considered a significant and ancient vector for the introduction of non-indigenous species at a global scale [68,69].…”

The impact and control of biofouling in marine aquaculture: a review

“…Historically, the aquaculture industry has borrowed antifouling (AF) technologies from other marine industries which focus on chemical AF technologies. AF paints to control biofouling are commonly used on surfaces in marine transport, oil and gas industries (Yebra et al 2004;de Nys and Guenther 2009;Du¨rr and Watson 2010). These paints leach biocidal compounds such as heavy metals and organic biocides onto the surface, producing a thin, toxic layer which prevents the onset of biofouling.…”

Drag on hydroid-fouled nets — An experimental approach

“…Increased biological growth has a negative impact on operations since it adds considerable weight to farming and culture equipment, threatens the stability of suspended culture systems, and reduces the lifespan of mooring lines (Braithwaite and McEvoy, 2004;De Nys and Guenther, 2009). Furthermore, biofouling also decreases the water exchange across nets, causing a reduction in water quality within enclosures and subsequently fish health (Braithwaite et al, 2007;Cronin et al, 1999;Dürr and Watson, 2009). Especially, since cleaner fish efficiency decreases when biofouling is present, leading to higher lice infections in the cultured salmon (Kvenseth, 1996).…”
