Between 2014 and 2016, experimental seine fishing was carried out in various sectors of the Saint-François River to detect the presence of small fish at risk (sand darter, channel darter) and to estimate the area of habitat suitable for their presence.
Although these species have been located in several places and some of these suitable habitats are present in sufficient quantity, it appears that some subpopulations do not include enough individuals to be viable in the long term. A number of threats may hinder the recovery of these species, including habitat modification by recreational boating, altered river flows, water pollution, biological control of insects, etc.
