Difference in catch rates under various depredation scenarios.

<p>Mean difference (Tukey’s honest statistical difference) in catch rates of the three main mammal scenarios to the no-mammal scenario around South Georgia. P—present, F—feeding. Originally 21 scenarios were calculated (orcas, sperm whales, fur seals: present/ absent, feeding/not feeding, and combinations of these) and the three most damaging scenarios to catch rates were chosen to be graphically represented. No-mammal-scenario average catch rates: Shag rocks = 300±0.06 g, North West = 233±0.05 g, North East = 276±0.07 g, South West = 253±0.05 g, and South East = 272±0.08 g of toothfish/hook. Stars denote difference between mammal scenarios.
