Poisoning invasive smallmouth bass to save the Miramichi River’s Atlantic salmon
Outdoor Canada is pleased to present Blue Fish Radio—podcasts about the future of fish and fishing in Canada. The program, produced and hosted by Lawrence Gunther, is dedicated to sharing first-hand angling knowledge, scientific discoveries and supporting local champions who protect and enhance their waters.
The Miramichi Salmon Association is one of several groups looking to eradicate invasive smallmouth bass from the Miramichi Lake and River. New Brunswick’s Miramichi watershed was once home to world-record runs of Atlantic salmon, but the population of this iconic species is now considered well below conservation levels. Making matters worse, in 2008, smallmouth were found in Miramichi Lake, where they had almost certainly been introduced illegally. And a decade later, these hardy, prolific bass were found in the Miramichi River.
Since then, both government and conservation groups have tried to eradicate the bass using methods such as netting and electrofishing, but those efforts have failed to contain the population. Today, scientists believe that the bass could do irreparable damage to native wild Atlantic salmon populations in the Miramichi.
In this episode of Blue Fish Radio, producer/host Lawrence Gunther talks to Mark Hambrook (above) from the Miramichi Salmon Association, who explains the plan to use the piscicide rotenone to eradicate these unfortunate bass and, hopefully, give the salmon a chance to recover.
