Awaiting seal pro nets but delayed due to covid issue, predator nets seal blind have been considered but not thought appropriate (further details to follow); They have a licence to dispatch. Dispatched in Loch Roag area.
Emailed update; "All nets have seal blinds fitted as standard, and this will be applied to the Seal Pros when they are deployed.
Predator nets are not used due to the damage that they can do to wildlife, plus the difficulty in keeping them clear of growth which has an impact on the water flow to the fish. A site like Taranaish, with a history of AGD which can escalate quickly would not be suitable for predator nets, for health and welfare reasons". [Original PDF]
