Dr. Jim Quinn of McMaster…

Dr. Jim Quinn of McMaster university is an expert biologist in cormorant ecology. He believes that the population has plateaued naturally so this intrusion into a natural system is unnecessary and excessive.
He also points out that the birds mostly feed on problem fish, ie invasive species like alewife and gobies.
Colonies often also contain other birds such as herons that would terrorized by cormorant hunting.
Colonies are often near heavily populated areas eg Hamilton harbour. Hunting would be dangerous to people nearby.
Human intervention often backfires. Please refer to the knowledge of experts like Dr. Quinn. Natural systems are under enough stress from habitat degradation and climate change without more interference from hunters.
