This is completely garbage…

This is completely garbage. There is no scientific basis for this. The only basis for this to appeal to the Ontario Federation of Anglers and Hunters to get rid of what they see as a "pest" bird that causes them inconvenience. Already this species have been damaged in North America through mismanagement:

"Despite the many studies indicating that cormorant diet in recent decades was largely nonnative forage fish and that cormorants have not negatively impacted the bass population in the Beaver Archipelago, cormorant control measures were implemented in 2007, specifically to protect bass. "

An action like this taken under the pretense of "conservation" actually damages the environment and ecosystems that are linked intricately to this species of Double Crested Cormorants. Additionally, there is very little impact to the long term proliferation of this species, but irreparable harm done to other interconnected species that ironically the lobbyist such as the OFAH rely on.

Basically, this is a politically expedient, ill (or not) thought out decision that has lasting and harmful environment impact. This is not projecture or rhetoric, this type of government action has been shown (in the above link) as being harmful at worst and ineffective at best.
