Abstract

Northern pike (Esox lucius) were stocked in and sampled from two diked Lake Erie wetlands from 1985 to 1987 to determine if there was selection for common carp (Cyprinus carpio), a nuisance species, and what effect a closed, shallow water environment would have on survival, growth, and reproduction of northern pike. In both wetlands, feeding was selective for soft-rayed prey, mainly carp and goldfish(Carassius auratus). There was also positive selection for larger soft-rayed prey versus spiny-rayed prey. The survival rate (13 percent) for West Marsh was low, but growth was greater than reported in the literature, and stocked northern pike successfully reproduced. In Darr Marsh, survival was not measured, growth was high, and there was no evidence of reproduction when sampling ended in summer.
