Atlantic salmon numbers drop for second year

The number of wild Atlantic salmon returning to North American rivers dropped 15 per cent in 2017 compared to the year before, reports the Atlantic Salmon Federation. Its latest report says only half of the 84 rivers it monitored met minimum requirements to sustain this species of fish.

The biggest decline was in Canada’s easternmost province of Newfoundland and Labrador.

Multi-year declines cited

Comparing year-to-year declines doesn’t give the whole pictures, said federation Neville Crabbe to Canadian Press. “When you pull back the lens and look at what’s happened since the 1970s, we’ve had multidecadal declines in wild Atlantic salmon populations throughout North America.”

The federation is going to raise the issue at a summit of the North Atlantic Salmon Conservation Organization taking place this week in Portland, Maine in the United States. It will ask national government delegations to take steps in their home waters to improve the situation. Among them, the federation will ask delegations to minimize or eliminate threats from open-net salmon farms, to prevent salmon fishing among threatened and endangered populations, and to ensure that all river fisheries are conducted sustainably.

Some conservation measures already helping

There are rivers that have relatively healthy returns thanks to conservation measures already in place. There is hope numbers will increase as a grateful federation lauded Greenland fishermen for recently agreeing to end their commercial fishing for 12 years, which should affect the return of salmon to North America.

Netiquette
When you express your personal opinion in an online forum, you must be as courteous as if you were speaking with someone face-to-face. Insults and personal attacks will not be tolerated. To disagree with an opinion, an idea or an event is one thing, but to show disrespect for other people is quite another. Great minds don’t always think alike—and that’s precisely what makes online dialogue so interesting and valuable.

Netiquette is the set of rules of conduct governing how you should behave when communicating via the Internet. Before you post a message to a blog or forum, it’s important to read and understand these rules. Otherwise, you may be banned from posting.
