VANCOUVER - First Nations say they're afraid that diesel fuel spilled from a sunken tug off British Columbia's central coast is affecting their food supply and other wildlife.

They point to the discovery of dead animals in the area.

The tugboat Nathan E. Stewart was carrying over 200,000 litres of diesel when it ran aground and sank about 28 kilometres from Bella Bella on Oct. 13.

A situation report says the volume of the spill is still being calculated based on what has been recovered or cleaned up, but current estimates show 105,000 litres of fuel leaked.

The report says wildlife assessment teams have spotted a dead humpback whale, a seal, a sea otter and crabs in the past week.

Kelly Brown, director of the Heiltsuk Integrated Resource Management Department, says it is “disturbing” to see the community's food and marine life being so severely affected
