In the January 2015 edition of InfoSuperior’s podcast, or audio interview series, Nipigon Bay Remedial Action Plan Coordinator Jim Bailey speaks with Rob Swainson, a former fisheries biologist with the Ontario Ministry of Natural Resources and Forestry (MNRF) who worked extensively on the Nipigon River. The interview touches on the importance of the Nipigon River to area residents as well as the restoration efforts made to assist fish populations, including coaster brook trout.
As a high-profile game fish with an international reputation, coaster brook trout are a unique variant among brook trout, not only because of their large size and silvery colour, but also their migration into tributaries for spawning in the fall.
Coasters migrate from rivers to a freshwater lake and back for spawning. Therefore they spend a significant portion of their life in Lake Superior’s Nipigon Bay. Named for their affinity to the coastal waters of Lake Superior, coasters are known for their large size and silvery colour while in the lake. They are highly prized by anglers. The world record brook trout (weighing in at 14.5 pounds) was in fact a coaster brook trout caught in the Nipigon River on July 21st, 1915. This catch still remains as one of the oldest unbroken fishing records.
During the spawning season, coasters regain the typical brook trout colouration and migrate up tributary rivers and creeks to spawn. It is at this time, when they are staging and spawning, that coaster brook trout are particularly vulnerable. Their large size and white leading-edged fins make them highly visible in the tea-coloured waters of the Nipigon River and it’s tributaries, creating easy targets for predators and anglers alike.
The status and range of coaster brook trout has been drastically reduced due to a variety of pressures, including habitat alteration, swings in water level due to hydro-electric power generation, pollution, exploitation and competition from introduced species including Pacific salmon and brown trout. The last remaining stronghold for coaster brook trout is Nipigon Bay, which contains almost half the known remaining coaster rivers and streams.
