Good containment is not just about purchasing the best possible equipment, but also ensuring that it is well maintained and regularly upgraded whenever required, says fish pen manufacturer Fusion Marine.
For example, the Argyll-based company has been busy over the last few months completing pen upgrades for a number of its customers. These include adding sinkers to pens for Scottish Sea Farms at their site on Lismore, and for Cooke Aquaculture Scotland in Orkney.
The Lismore project was aimed at improving net volume in a strong-current environment to ensure optimum quality of the salmon, whilst the Orkney project was a focused on tensioning across the base of the net to discourage seal attacks.
Fish pen upgrades have also recently been carried out for The Scottish Salmon Company at Stronachullin and for Dawnfresh at Braevallich.
According to Stephen Divers, managing director of Fusion Marine, steady progress is being made by both fish famers and suppliers towards complying with the new Scottish Technical Standard by improving the containment of existing infrastructure.
He added: “From our own perspective, we are continually involved in new development initiatives to enhance containment, especially given the future trend to move to more exposed offshore sites.
“This has included work to improve the performance of the fish farm pen flotation collar on high energy and exposed sea sites. We have also been developing new sub-surface components for sinker tube systems to minimise abrasion and other net integrity issues whilst meeting the operational needs of the customer.”
