With Argyll and the Isles fairly substantially implicated in this, the conservation body, Salmon & Trout Association Scotland [STAS] have issued a call for urgent action, following the latest aggregated sea lice data published by the Scottish Salmon Producers Organisation [SSPO].
These data show that in the first quarter of 2014, sea lice numbers on farmed salmon were still out of control in a number of regions – just when migrating juvenile salmon and trout are going to sea for the first time, through the polluted waters.
The second quarter of every year is when the main migrations to sea of juvenile wild salmon and sea-trout occur.
During this period they are at their most vulnerable to damaging and often fatal infestations of sea lice emanating from fish farms.
The latest SSPO quarterly sea lice report [for January to March 2014], reveals that average lice numbers were over thresholds, often very considerably over, in almost 50% – 14 out of 30 – of regions for which data is reported by the industry.
Particular hotspots, for the fifth quarterly report in a row, include ‘Kennart to Gruinard’ in Wester Ross where there are seven farms operated by two companies, Wester Ross Fisheries Limited and Scottish Sea Farms Limited.
Although three of the sites were fallow during the latest quarter, the farms at Ardmair, Corry and Tanera [two sites, 1 and 2], collectively breached industry sea-lice standards and will have been producing juvenile sea-lice in numbers that would threaten the survival of any migrating young wild salmon and sea-trout leaving the rivers of Wester Ross for the first time.
This will almost certainly include wild salmon from the Special Area for Conservation on the Little Gruinard River, where Atlantic salmon are strictly protected under European law.
Sea-lice have been over the threshold in this part of Wester Ross for 15 straight months now. Despite three area-wide sea-lice treatments last year, one this year – and a staggering 32 other treatments for lice within a 15 month period, the industry here still cannot get its sea-lice problem under control.
Other regions also had sea lice levels well over the thresholds for treatment, threatening migrating wild salmon and sea-trout with lethal infestation. These include several in Argyll:
- Loch Long and Croe [Argyll and the Isles]
- Awe and Nell [Argyll and the Isles]
- Add and Ormsary [Argyll and the Isles]
- Mull, Islay and Jura [Argyll and the Isles]
- Inchard to Kirkaig North,
- Kishorn and Carron,
- Morar to Shiel,
- Skye and small isles [North],
- East of Lewis
- North Uist
- South Uist
- Shetland East.
Hugh Campbell Adamson, Chairman of the Salmon & Trout Association [Scotland] [S&TAS], says: ‘In Norway, the fish farmers have been read the riot act over lice. In Scotland, they have been invited to trade dinners and cosy chats. All the assurances and promises made in recent months by the Minister, for example during the passage of the Aquaculture and Fisheries Act through Holyrood, ring rather hollow.
‘There are regions of Scotland where the fish-farmers demonstrably cannot control sea-lice on farmed fish. The industry also includes serial offenders, who seem either unwilling or incapable of controlling their sea lice but, collectively, the industry does not seem prepared to deal with its own ‘bad apples’.
‘In both cases, the Minister must now act. For him to say that he is keeping the situation ‘under review’ is no longer credible. He should direct Scottish regulators to require prolonged fallowing of entire regions where sea lice are out of control [and not just the odd farm for a few weeks]. Then there should be a thorough examination of whether fish-farming can continue in these regions.
Given the particularly appalling track record in Loch Broom and Little Loch Broom, the S&TA is already very clear that we should now stop current farming fish in Two Brooms completely’.
Guy Linley-Adams, Solicitor to the S&TA(S) Aquaculture Campaign, said: ‘What is very concerning is that each new set of data suggests increased sea lice resistance to the cocktail of drugs used to control sea-lice. It also seems in some regions the use of wrasse as ‘miracle’ cleaner fish has been rather over-hyped.
‘We would ask Ministers again to consider ordering a cull of all the fish in the very worst affected regions – for example, between Kinlochbervie and Gruinard Bay. This is the kind of decisive action taken by the Norwegian authorities when they were faced with a similar problem. This should then be followed by the fallowing of these farms until such time as a proven solution is identified.
‘The question is whether Ministers are prepared to provide any protection whatsoever for wild salmon and sea-trout in the worst affected regions, or whether they will continue to protect the salmon farmers, come what may’.
Paul Knight, S&TA’s CEO and Co-Chair of the NGOs attending the 31st Annual Meeting of the North Atlantic Salmon Conservation Organisation [NASCO] says: ‘This set of data is especially topical as the NASCO meeting is showing a stark difference in the attitude of Scotland and Norway in lice management.
‘Norway seems determined to take tough decisions in an attempt to protect wild salmon, while the Scottish Government consistently turns a blind eye to industry failures to adhere to internationally recognised environmental standards.
‘Meanwhile, the SSPO continues to be in denial over the impact of sea lice emanating from fish farms on wild fish.
There is little doubt that Scotland is out on a limb amongst its NASCO colleagues by failing to protect wild salmon and sea trout from the dangers of poorly operated aquaculture.’
