Book Description

Surveys for black redhorse (Moxostoma duquesnei) and spotted gar (Lepisosteus oculatus), both Threatened fish species, were undertaken by Fisheries and Oceans Canada during the summer of 2002 to determine their current status at sites where they had been historically present. Boat electrofishing, backpack electrofishing, fyke netting and trap netting were used during the sampling. At sites where they were historically present, black redhorse were captured at 2 of 7 Thames River sites (the Middle Thames River and Medway Creek), all 3 Maitland River sites (including Belgrave Creek), and 4 of the 7 Grand River sites. They were also caught at the following sites where they were not collected historically: in 3 of 14 Nith River sites; and, 1 of 2 Conestoga River sites. The spotted gar was detected at 13 sites: 7 sites in Rondeau Bay; and, 6 sites in Point Pelee National Park.
