Greenland/Labrador Wild Salmon Collapse; Since 1990, #s Have Gone From From 8 Million To 1-2 Million
EDIT
Nothing does make sense, at least not yet, about what has been happening to Atlantic salmon since 1990. Until 1989, an estimated eight to 12 per cent of Atlantic salmon survived their journeys from home rivers to northern waters off Labrador and Greenland, to then come back and spawn. In 1990, that plummeted to between one and four per cent.
The total population crashed too — from an estimated eight million salmon alive on either side of the Atlantic to between one- and two-million fish. It hasn’t gotten better since.
“The timing of that is concurrent with the major cod collapse and a major shift in oceanographic and climate patterns,” said Edmund Halfyard, a research scientist for the Nova Scotia Salmon Association.
“We’ve seen evidence of this shift in everything from phytoplankton and capelin up to large commercial fish species and even predators like gannets and seals. Everything shifted at about the same time period. It’s a new ocean.” This story isn’t about gannets or cod, although they’re important too. It’s about salmon because their lives rely on both the health of land and sea.
