Trap and Transport of large American eels in Upper St. Lawrence River – Implications for Turbine Mortality Mitigation
Based on morphometric characteristics and silvering indices there are no differences between wild migrants and transported silver eels captured in the Quebec fishery. Evaluation of migration rates between transported and reference silver eels show that after 3 years there is no difference in the overall migration rate. While some differences exist between wild migrating and T&T eels, overall migrating T&T eels had a normal rate of gonadal maturation and similar body fat content as wild migrants.
A criticism of T&T is the inability to capture and transport large numbers of yellow eels. Currently, up to 2200 large yellow eels can be captured per year by commercial fishers in Ontario waters of the upper St. Lawrence River and Lake Ontario.
