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?

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?

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?

• Prevents dolphin deaths

Illegal Gill Nets Recovered, 2002-03

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?
