Summary

For almost two decades Little Galloo Island (LGI)has supported the largest colony of double-crested cormorants (Phalacrocorax auritus) in the eastern basin of Lake Ontario. Cormorant nest counts on the island since the early 1990's have averaged about 5,000 per year reaching a high of 8,400 in 1996. Johnson et al. (2008) estimate that cormorants from LGI alone have consumed 400 million fish since 1992. The proliferation of cormorants in the eastern basin of Lake Ontario has coincided with declines in two important recreational fish species, smallmouth bass and yellow perch. Lantry et al. (2002) and Burnett et al. (2002) provide convincing evidence linking cormorant population increases to declining eastern basin smallmouth bass and [...]
