A Simon Fraser University-led research team has found significant evidence that human activity in estuaries is impacting juvenile Pacific and Atlantic salmon. The team’s review of 167 peer-reviewed studies (from an initial search of 13,000) identified negative impacts from several stressors, including the effects of flood-protecting tidal gates, pollution and habitat modification.
Their results were published today in Global Change Biology.
Emma Hodgson, an SFU postdoctoral researcher at the time of the research and lead author on the paper, says the review is the first to synthesize what is known, and not known, about how human activities in estuaries may impact juvenile salmon.
“Risk can be defined by the severity of the impact and the certainty we have about whether that impact is likely—that certainty is based on the amount of evidence and…
