“…Most non-biocidal alternatives seal net surfaces under wax-or resin-based coatings. The aim is to reduce surface structure and texture to create a less favourable settlement surface in addition to increasing resilience to net cleaning (Swain and Shinjo 2014;Edwards et al 2015;Baum et al 2017). Alternative net materials such as HDPE ('Dyneema') or PET monofilaments ('Kikko net') are also used with similar intention.…”

“…Alternative net materials such as HDPE ('Dyneema') or PET monofilaments ('Kikko net') are also used with similar intention. While this technology can delay the onset and reduce the accumulation of biofouling compared to regular, uncoated raschel-knitted nylon nets (Edwards et al 2015;Baum et al 2017), they do not outperform conventional copper coated nets (Edwards et al 2015;.…”

Biofouling in marine aquaculture: a review of recent research and developments

et al. 2019

View full text Add to dashboard Cite

Biofouling in marine aquaculture is one of the main barriers to efficient and sustainable production. Owing to the growth of aquaculture globally, it is pertinent to update previous reviews to inform management and guide future research. Here, the authors highlight recent research and developments on the impacts, prevention and control of biofouling in shellfish, finfish and seaweed aquaculture, and the significant gaps that still exist in aquaculturalists' capacity to manage it. Antifouling methods are being explored and developed; these are centred on harnessing naturally occurring antifouling properties, culturing fouling-resistant genotypes, and improving farming strategies by adopting more sensitive and informative monitoring and modelling capabilities together with novel cleaning equipment. While no simple, quick-fix solutions to biofouling management in existing aquaculture industry situations have been developed, the expectation is that effective methods are likely to evolve as aquaculture develops into emerging culture scenarios, which will undoubtedly influence the path for future solutions.

“…Our findings corroborate reports that nets made from other materials with a smooth surface (e.g., HDPE or polyethylene terephthalate monofilament) are less susceptible to biofouling and are easier to clean (Edwards et al., 2015). Therefore, we recommend using HDPE nets because they have a smaller surface area upon which biofouling organisms can settle, and they are easier to keep clean than Nylon (Baum et al., 2017; Edwards et al., 2015).…”

Research into Piscirickettsia salmonis biofilms on materials commonly used in salmon farming is crucial for understanding its persistence and virulence. We used the CDC Biofilm Reactor to investigate P. salmonis (LF-89 and EM-90) biofilm formation on Nylon, Stainless steel (316L), Polycarbonate and High-Density Polyethylene (HDPE) surfaces. After 144 h of biofilm visualization by scanning confocal laser microscopy under batch growth conditions, Nylon coupons generated the greatest biofilm formation and coverage compared to Stainless steel (316L), Polycarbonate and HDPE.Additionally, P. salmonis biofilm formation on Nylon was significantly greater (p ≤ .01) than Stainless steel (316L), Polycarbonate and HDPE at 288 h. We used Nylon coupons to determine the kinetic parameters of the planktonic and biofilm phases of P. salmonis. The two strains had similar latencies in the planktonic phase; however, LF-89 maximum growth was 2.5 orders of magnitude higher (Log cell ml −1 ). Additionally, LF-89 had a specified growth rate (µmax) of 0.0177 ± 0.006 h −1 and a generation time of 39.2 h. This study contributes to a deeper understanding of the biofilm formation by P. salmonis and elucidates the impact of the biofilm on aquaculture systems.

“…While uncoated nets can be utilised for this strategy, the addition of a non-biocidal coating may help to protect the net from UV radiation damage and abrasion by frequent cleaning. The use of such coatings serves to seal the surface of the net, resulting in reduced surface roughness and, potentially, colonisation rates (Baum et al 2017). Reduced surface roughness can also help to improve removal of biofouling organisms (Hodson et al 2000;Swain & Shinjo 2014).…”

Towards cost‐effective biofouling management in salmon aquaculture: a strategic outlook

Biofouling is an ongoing challenge for marine salmon aquaculture, impacting farming operations, fish health and welfare. Current mitigation strategies employed in Norway and Scotland rely mainly on the use of antifouling coatings and reactive removal of biofouling. These approaches are not only costly and of limited efficacy, but also pose active risks and likely contribute to mortality of fish during grow‐out at sea. Given the inefficiencies of current biofouling management approaches and the industry’s objectives for growth and sustainability, a strategic assessment of future avenues for biofouling management is needed. We here present such an assessment and outline three novel biofouling management strategies that, once implemented, could facilitate improved fish health and welfare, reduced environmental impacts and benefits to the public perception of fish farming. These strategies are based on: (i) efficient antifouling coatings; (ii) antifouling combined with intermittent cleaning; and (iii) grooming of nets. We discuss the advantages, challenges and research and development needs associated with the realisation of these strategies. Drawing on experiences from agricultural systems and invasive species management, we show how the costs involved in the implementation of new strategies will over time be offset by the direct and indirect benefits arising from a reduction in environmental and fish health impacts and an increase in the industry’s social licence to operate.
