Coastal predation
Legal & illegal nettingDolphins & seals
• Catching 8,000 fish
• 130 dolphins
• 15 netting stations
• 700 common seals
• 300 grey seals
• Catching ? fish
180,000 salmon 80,000 sea trout

The SAC Conundrum
• Salmon (PREYPREY) are declining
• Common seals (PREDATORPREDATOR) are declining
• Bottlenose dolphins (PREDATORPREDATOR) are declining
• Common and grey seals (PREDATORPREDATOR) are protected in the Moray Firth by Conservation Order (2002-2004) due to PDV outbreak
WHICH SPECIES TAKES PRIORITY?
![Page 10: Integrating Salmon and Sea Trout within Management of the Moray Firth Dr. James Butler (Director, Spey Fishery Board)](https://reader038.fdocuments.in/reader038/viewer/2022110101/56649e755503460f94b76ecc/html5/thumbnails/10.jpg)
What actions are impossibleimpossible?
1. Culling dolphins
• SAC population declining
• Source of tourist income (£720,000 per year)
2. Culling common seals
• SAC population declining
• Contribute to tourist income

What actions are possiblepossible?
1. Targeting problem seals in river mouths?
• Most damage done by few problem animals?
• Grey seals not in decline and outwith common seal SAC
• Management plan for Moray Firth seals needed
• Process begun by Scottish Executive pre-PDV but stalled
• Appropriate methods: lethal or non-lethal?

What actions are possiblepossible?
2. Reduce salmon netting?
• Declining surplus
• Mixed-stock interceptory fisheries
• Would reduced catch buffer dolphin and seal predation?
• BUT economic impact on traditional activity?
![Page 13: Integrating Salmon and Sea Trout within Management of the Moray Firth Dr. James Butler (Director, Spey Fishery Board)](https://reader038.fdocuments.in/reader038/viewer/2022110101/56649e755503460f94b76ecc/html5/thumbnails/13.jpg)
What actions are possiblepossible?
3. Reduce pelagic fishery?
• Pelagic fish are basic diet for all predators in Moray Firth
• Would reduced catch benefit salmon and sea trout feeding?
• Would reduced catch buffer dolphin and seal predation on salmon and sea trout?
• BUT difficulties of dealing with North Sea fisheries policies

What actions are possiblepossible?
4. Relocate salmon aquaculture?
• No risk of disease or escapes on wild salmon and sea trout
• Scottish Executive Aquaculture Strategy and TWG reviewing location of salmon farms
• No current salmon farm production in Moray Firth
• Relocate freshwater salmon farm cage sites?

Dolphin deaths from illegal gill nets
Fishery Board patrols
• Reduces salmon losses
• Prevents dolphin deaths

Possible Moray Firth action
1. Seal management plan?
2. Review salmon netting?
4. Relocate salmon farms?
3. Review commercial pelagic fisheries?
5. Expand Operation Fish Net?
