he almost incessant storms that battered swathes of the British Isles this winter have
helped to illustrate the need to err on the side of caution when it comes to keeping your fi sh contained, with at least two considerable weather-related es- cape incidents – one in Shetland and one in Ireland’s Bantry Bay – occurring, which accounted for the loss of almost 400,000 fi sh between them. However, as is becoming
increasingly apparent, a far more precise science is required than purely beefi ng up all specifi ca- tions of ropes, nets, moorings and anchors. Indeed, there are far more technical considerations required to survive a 50-year storm, and it is interesting to read how fi ne-tuning can often be more important than merely increasing your specs – with innovations such as Mørenot’s Flexilink system offering useful alternatives to the steel-based status quo that has dominated
mooring systems for several decades.
PREDATION As well as the weather the
other main threat is, of course, from predators – with seals being the most widespread problem facing marine sites in Scotland – and it is clear that there have been a number of advances in this area too. Hvalpsund’s recent trials in Tasmania, where seal- based predation is rife, appear to offer a long-term solution to the
