Fisheries committee  I don't think a new name would help. It depends on the action. We need the resources; we need the people. There are many people who will give you way too much good advice, so you need people who can really sort those out. There was a good question earlier about a 1,000 random pro

Fisheries committee  Could I make a comment on that?

Fisheries committee  I don't disagree with anything we just heard there, except I want to point out that when you talk about Russia and others, they are producing a different species in the hatcheries—these huge numbers. They are not doing this with the chinook and coho. They have some hatcheries for

Fisheries committee  Maybe I could start again, gentlemen. I think the best example is in Russia. They have a very large pink and chum hatchery program. In 2000 they lost 40% of their catch in one year. Their hatcheries didn't change in any way, but the ocean environment was so much different that th

Fisheries committee  It was a concern of mine, but I think it's a bit dated now because the trawl fisheries that you're talking about and their effect on salmon were in the extreme North Pacific and in the Bering Sea. The Bering Sea pollock used to be the largest fishery in the world. It was highly p

Fisheries committee  I wouldn't say enough to do the adapting. We have developed the tools you could use. Now it's a matter of how you implement them. But there's not a great deal of additional money in the enhancement program, where they want to spend more money, so there's been slow take-up of some

Dr. Brian E. Riddell

Fisheries committee  I can maybe start on this. I think what you're perceiving is correct. In the scientific community, there is very definitely a split. Recent COSEWIC decisions about west coast salmon really criticized industrial-scale hatcheries. These are the large mega hatcheries, not the commu

Fisheries committee  If a tool was mentioned, I don't think it was about the chemical analyses we're doing, but probably more in the context of major hatcheries. Major hatcheries are seen as a management tool. As you just heard, they can produce large numbers of fish. But the intention in doing that

Fisheries committee  We've only really investigated at that degree of detail for one virus, and that was the piscine orthoreovirus. It's the one that's been in the media many times, related to the heart and skeletal muscle inflamation disease. We have done a very careful genetic study of its origin,

Fisheries committee  I'm not sure what you're referring to from PSF in the Nass. We've not done that. If there was such a study, it was a very old review. There are many factors involved with this, because the Nass Valley is also very much less developed. There's a huge difference there, to start w

April 14th, 2021Committee meeting

Dr. Brian E. Riddell

Fisheries committee  Well, unfortunately, what we're talking about here really is a mix of biology, sociology and cultures. This is not a straightforward thing that you should do this, yes or no. You could certainly do elements of this, and I have been promoting the consideration of mass marking, bec

April 14th, 2021Committee meeting

Dr. Brian E. Riddell

Fisheries committee  Well, I think it could be improved, but I mean hatcheries can have very different objectives. The major hatcheries that the salmon enhancement program has built were built to provide fish to commercial fishing and also to recreational fishing as they changed the species compositi

Dr. Brian E. Riddell

Fisheries committee  I think we can work within whatever system of bureaucracy we have in place. We really must have the commitment to the resources, and we can then develop the plan just the way Josh said. You could have regional committees that really know their environment. The limitation of that

Dr. Brian E. Riddell

Fisheries committee  It's an interesting question. Canada is a very small player in the hatchery production game. The massive programs in Japan and Russia and in elements of Alaska really produce a hundredfold times more fish than we do in that. The problem is that the fish will mix in the ocean. Wh
