Salmon officials confirm first application of rotenone in Miramichi watershed

After years of protest, a pesticide has been released in the Miramichi watershed as part of a project to eradicate the invasive smallmouth bass. Salmon conservation groups confirm Sept. 8 marked the first application of Noxfish II, a chemical that includes rotenone. It was released in Lake Brook and approximately 15 kilometres of the Southwest Miramichi River.

The project to eradicate invasive smallmouth bass from Miramichi Lake by using rotenone is now underway, according to people who oppose the plan. On Thursday, Indigenous opponents of the project were again canoeing on the lake to prevent workers from pouring the toxin into the water. This is what prevented the project from going ahead last year, because the chemical can't be applied when there are people on the water. There are also unconfirmed reports of an arrest. According to multiple sources, including opponent and cottage-owner Barb Hildebrand, one of the people camping on the beach in the hopes of waylaying the project was arrested by provincial peace officers Thursday and accused of theft.

Chemical spraying to kill invasive bass is back on for Miramichi watershed

After opponents stopped the project last year, chemical spraying to wipe out an invasive bass population in Miramichi Lake is set to take place later this summer. Last year's attempt to eradicate smallmouth bass was halted because Wolastoqey grandmothers and mothers concerned about the environmental impact of the spray took to the lake in canoes. It is unsafe to spray rotenone, the fish-killing pesticide being used, when people are on the water.

A plan to begin applying the fish-killing pesticide rotenone to sections of the Miramichi watershed has been delayed by at least one day, the Atlantic Salmon Federation says. Earlier this year, the Department of Fisheries and Oceans gave the green light to eradicate smallmouth bass, an invasive species, by spraying sections of the Miramichi watershed beginning on Tuesday. The Atlantic Salmon Federation and the North Shore Micmac District Council have been pushing for the project to protect salmon for several years now, and originally hoped it would go ahead last summer. The federation has said smallmouth bass threaten salmon and trout by taking over their food and habitat.

DFO considers release of toxins to control an invasive species in Miramichi Lake

Officials at Canada's Department of Fisheries and Oceans are weighing in on a troublesome question. Should they allow a healthy lake to be poisoned — even temporarily — to avert a potential disaster for the Miramichi River's wild Atlantic salmon? That question became urgent this fall with the discovery of dozens of smallmouth bass had appeared in Miramichi's southwest branch.
