OHTF liaise closely with the Aquaculture industry and its some 70 sites throughout the Western Isles, aiming to ensure healthy and thriving wild fish populations along side a sustainable industry.
The potential negatives effects arising from fish farms are mainly attributed to sea lice and escaped farm fish. It is a key function of the Trust, with our interactions taking on many forms including; sea lice monitoring (post smolt sweep netting), assisting the WIDSFB with planning responses as a statutory consultee, representing wild fisheries on Area Management Agreements (AMA's) and working partnerships. There are currently two Area Management Agreemements - Loch Erisort and Loch Roag, established in October and November 2014 respectively.
Area Management Agreements
Within each AMA there is a group of designated individuals representing aquaculture and wild fishery interests. This is known as the Area Management Group (AMG). The AMG for each area meets biannually.
The purpose of the Area Management Agreements is to promote local industry and wild fisheries interests throughout the west coast and Western Isles and cover a range of objectives, including:
single year class management and synchronised production/fallowing cycles
Synchronised lice treatments
zero ovigerous salmon lice, particularly during the critical wild smolt migration period (Feb – June)
vaccination of smolts against furunculosis
preparation of containment and contingency plans to minimise escapes
adherence to industry Codes of Practice
regular monitoring and information exchange between AMA partners
preparation of catchment management plans
adherence to disease control mechanisms in wild fisheries
possibility of augmenting with biological control using wrasse cleaner fish
OHFT are actively seeking better regulation of the Aquaculture industry by lobbying alongside other Boards and Trusts from the Aquaculture zone and Fisheries Management Scotland. We are awaiting the outcome of the recent Rural Economy and Connectivity AMA's report.
