West River – Sheet Harbour Hosts Atlantic Salmon Spawners!
As the year comes to a close, we can count our
blessings and reflect upon positive developments of 2009. This year we saw an important chapter in the ongoing survival struggle
of Nova Scotia’s wild Atlantic salmon. The following is from an October 20, 2009 press release by the Atlantic Salmon
Federation.
This fall Atlantic salmon researchers
and conservationists released 332 ready-to-spawn salmon into West River - Sheet Harbour at undisclosed locations near Sheet
Harbour, just in time for spawning season. This was one in many steps of a long-term program undertaken by the Atlantic Salmon
Federation (ASF), and the Nova Scotia Salmon Association (NSSA), and other partners to restore wild Atlantic salmon to the
river after their numbers were decimated by the effects of acid rain.
In 2005, ASF, NSSA and other partners installed
Canada's first lime doser, on the West River at Sheet Harbour to help mitigate against the damage caused to the river
and its fish populations by acid rain. This Norwegian-built doser automatically distributes lime to neutralize the acid
in the water. Since the doser's introduction four years ago, the water has gradually improved and has now reached
a pH balance that can support salmon again. There are even reports of juvenile salmon having been seen in the limed
parts of the river that have not seen fish for decades because of the river's high acidity levels.
In addition
to the ready-to-spawn salmon, for the first time since the acid mitigation program began, researchers stocked the river with
35,000 unfed salmon fry, the progeny of wild 2007 smolts, reared to maturity at the Fisheries and Oceans Coldbrook Biodiversity
Facility. They were released in areas where no salmon have been found due to low pH. The spawners were also raised at
the biodiversity facility from salmon caught two years ago as part of the facility's gene banking program.
For a second consecutive year, researchers also implanted some West River smolts with acoustic tags to follow
their migration movements from the river to the ocean as part of ASF's ocean tracking program to determine why so many
salmon are failing to return to their birth rivers. Researchers estimate that 2,500 smolts migrated from the West River
this year.
Lewis Hinks, ASF's NS Regional Director, says, "We are excited that after many years
of planning, raising money, and working to restore West River - Sheet Harbour, that we have reached these milestones.
We still have a lot of work ahead, but hopefully, next year, we will find thousands of salmon fry in the river. That
will make it all worthwhile."
George Ferguson, VP, NSSA, and West River Program Manager, agrees and
adds, "We are gradually returning this river to a healthy state; that bodes well for Nova Scotia's 53 other acid-impacted
rivers. We many have to restore them one at a time, but at least, we know that with hard work and diligence they can
be restored."
Merry Christmas
