Channel catfish, a non-native species to New Brunswick, has been confirmed in Grand Lake, Queens County. This is the result of an illegal introduction into the province. This freshwater fish species belongs to the Ictaluridae (Catfish) family and is a voracious eater. Their diet can include crayfish, frogs, fish, and snails. They grow much larger than the native bullhead, averaging 36-61 cm (14-24 in) and larger, compared to the bullhead’s 20-26 cm (8-14 in). Their larger size and varied diet could result in outcompeting the native bullhead and impact native populations of preyed on species.
