Summary
The first of three reports from Grant Sonnex in Alaska, following the last great Salmon run. Sockeye Salmon begin their migration in Bristol Bay, where they must dodge fishermen’s nets to reach the freshwater rivers where they spawn. Elsewhere, Philippa reviews this year's northward Gray Whale migration. They left their Mexican nursing lagoons in spring and have now reached their summer feeding grounds off the coast of Alaska but climate change seems to be affecting calf production.
