Smallmouth bass numbers no longer identified
There is not any estimate of the dimensions of the smallmouth bass inhabitants within the lake, however Crabbe stated the quantity is “beside the point” as it takes only a handful of the invasive fish to start out a inhabitants.
“The risk stays the similar whether or not you will have six or 6,000,” Crabbe stated. “A inhabitants estimate is insignificant.”
A 2018 file through DFO stated the inhabitants in Miramichi Lake is most likely small, since catch charges from strategies equivalent to electrofishing and gill nets have been low.
Whilst there’s an odour related to the rotenone product, Crabbe stated it will be short-lived.
