DescriptionThe River Redhorse, a rare sucker, was angled in the Trent River at Trenton by Geoff Bernardo in 1997. He correctly identified the fish, which is difficult to do even for professional biologists. Bernardo brought the fish (4.0 kg or 8.73 lbs, 73.7 cm or 29 in) to the ROM to be positively identified. He had not only angled a Canadian record-sized River Redhorse (which has since been superceded by a fish that is 0.7 kg heavier), but more importantly, discovered a new population of this species—the first from the Lake Ontario watershed. \\r\\n\\r\\nThe Committee on the Status of Endangered Wildlife in Canada considers this species as Special Concern—particularly sensitive to human activities or natural events but not an Endangered or Threatened species. Later fieldwork in the area by the ROM and the Ministry of Natural Resources indicated that there was a healthy population, including the example pictured here. The river redhorse has club-like throat teeth, which enable it to crush and eat mussels, like the exotic zebra mussel that are common throughout the Trent River.
