Again, I'm not an aquatic biologist. I can't quantify the cod predation. This is a factor that has been mentioned. It has been studied. What I know is that there are different arguments for and against, so I do understand that it's part of the problem. It's part of the reason why cod are not recovering, but I certainly do not, as an expert in conservation, think that is the main driver.
