Environment committee  Biomagnification is the process where a hydrophobic contaminant, but also mercury, increases up a food chain with each trophic level. The predator has more than the prey; its predator has even more, and that's why we call it biomagnification.

Environment committee  I don't know about the water quality in Toronto harbour. I haven't heard of major algal blooms there, but there are nearshore fouling issues all along the north shore of Lake Ontario. We had funding for some time from OPG because of the nuclear power plants being clogged by nears

Environment committee  The Humber River bloom, and so forth, yes.

Environment committee  There isn't one right now, but I could imagine having imaginative fisheries scientists in the room and asking what eats mussels and what can we do in terms of management of the fishery to enhance those species. That's not even being discussed as far as I'm aware. It's not even be

Environment committee  Probably not. I wouldn't advocate it.

Environment committee  I'll just add a little bit. I know that my conservation authority, and I think all of them in Ontario, do receive provincial funding as well as from the municipal governments and raise their own money. What would really help them is if they were eligible to be industrial partners

Environment committee  Yes, I expect those data are available, but I can't speak to them.

Environment committee  That's a difficult question. Fish habitat, as Dr. Chow-Fraser is talking about it, is mostly spawning habitat in wetlands and tributaries and so forth, so those are critical habitats that have to be protected for fishery production. I was talking about the growth of fish in t

Environment committee  I don't know, but I don't think there's an analogous situation in Canada to the Great Lakes and their issues. So I don't know; I can't cite a jurisdiction that takes a more holistic view. I think it's more commonly done in Europe. The Europeans are very aware that the fish stock

Environment committee  I can only concur. It's all about habitat. I mean, fisheries management; it's a bit of a strange term. We can manage people, and we can do what we can do to fix the habitat. We really can't manage fish. They do what they want.

Environment committee  Yes.

Environment committee  Certainly, there are more sophisticated models that we could apply now. On the other hand, they are also very data hungry models. I don't know whether for a research program data could be collected to supply a more sophisticated model for an area in the Great Lakes. It's common

Environment committee  Of the returning fish, 85% are wild, but they're still stocking huge numbers of fish into the lake, and those fish are simply starving.

Environment committee  When there is too much phosphorus and you get blooms of those same algae that are harmful to humans, they are also unsuitable food for those zooplanktons. They can't feed on them and they're toxic. In some cases it's because if there are not enough top predators those alewives

Environment committee  I would like to see the mandate of the Great Lakes Fishery Commission broadened to managing the whole fishery, not just the native species as they focus on now, and I would like to see the management of the water quality, which is mostly given to the IJC and the management of the
