Endocrine disrupters may kill salmon at sea

A study by researchers with the Department of Fisheries and Oceans and Environment Canada has found that past spraying programs against the spruce budworm may be behind the disappearance of salmon at sea.

The spraying may be releasing endocrine disrupters which impair salmon’s ability to change from freshwater to saltwater fish. The discovery may explain why seemingly healthy young salmon leave their spawning rivers and then vanish at sea.
