River Otters have been observed preying on adult Sockeye Salmon
(Oncorhynchus nerka) in Lake Ozette and the Ozette River (Haggerty and others 2009a), which is a cause for concern because Lake Ozette Sockeye Salmon
are a unique evolutionary significant unit of Sockeye Salmon
and are listed as Threatened under the US Endangered Species Act (ESA) due to low and declining population numbers (64 FR 14528, 25 March 1999).
They have reported declines in salmon spawning in the headwaters and the possible extirpation of one type of sockeye salmon
that spawns in Tanada Lake and attribute these changes to increased noise, water pollution, and other changes in spawning areas caused by human activities.
Specifically, rates of mortality of juvenile sockeye salmon
infested with gill lice increased in relatively warm (23[degrees]C) water.
Summary: TEHRAN (FNA)- When migrating, sockeye salmon
typically swim up to 4,000 miles into the ocean and then, years later, navigate back to the upstream reaches of the rivers in which they were born to spawn their young.
In the study, scientists examined 56 years of fisheries data documenting the return of sockeye salmon
to the Fraser River in British Columbia - and the route they chose around Vancouver Island showed a correlation with changes in the intensity of the geomagnetic field.
In addition, there are clear linkages between ex-vessel prices for sockeye salmon
from Alaska and the supply of Chilean pen-reared coho and steelhead shipped into Japanese markets.
Meanwhile, Waitrose said sales of sockeye salmon
nearly trebled, and yellowfin tuna was up nearly a half, while tomatoes, salads and ice cream were popular.

The miraculous sockeye salmon
run in western Canada's Fraser River watershed in the summer and fall of 2010--indeed the biggest run in 97 years--still has fishers, researchers and fishery managers baffled.
