The Government of Ontario…

The Government of Ontario says it is responding to concerns about too many cormorants, depleted fish stocks and environmental damage. But those concerns are largely just anecdotes, complaints from a small, radical segment of the fishing community, and unsubstantiated claims that were debunked long ago. There is no substantive body of evidence proving that cormorants are depleting fish stocks or causing any ecological problems whatsoever.

The reality is that cormorants are a natural part of Ontario’s rich biodiversity and an ecologically beneficial species, being major predators of invasive fish species, like round gobies and alewives, attracting other waterbirds to their nesting sites, and serving other important functions in the ecosystems they inhabit.

Radical cormorant-haters have already attacked colonies under cover of night, destroying nests, stomping on chicks and killing adults. Once the proposed changes to the law come into effect, these people will be given free rein to destroy as many cormorants as they want. It wouldn’t take very many people very long to wipe out most cormorants in the province, leaving just a tiny remnant of their population in a few protected areas. And driving them back to near extinction or even worse in Ontario is a real possibility.

Cormorants are beneficial because their diet consists of very large numbers of primarily invasive fish, such as alewives and round gobies, as well as other non-commercial, non-forage species. The mass killing of cormorants will damage the environment and disrupt natural ecosystem processes.
