First, I would say that in Canada we have a very distorted vision of aquaculture. We think it is only fish aquaculture. I always repeat that, worldwide, the largest crop produced in aquaculture—46%—is seaweed, mostly in Asia, which is why we in the western world don't know about that. Forty-six percent of aquaculture is seaweed and 43% is shellfish. We talk a lot about fish, but fish aquaculture is only 8.9%.
In the future, aquaculture will not be only fish production; it has to be fish, shellfish, and seaweed production. People will also have to consider eating shellfish and seaweed. In Asia, it's not complicated; in the western world, it is complicated.
We are working on substituting seaweed in fishmeal. At the present time in New Brunswick, there are several strategies. There is reducing fishmeal by using trimmings discarded from fish ponds. As a matter of fact, it's still good fish protein for the fish, so the use of trimmings reduces little-fish fisheries. Then there is a percentage that can be replaced by land plant proteins. And we are working on replacing or substituting a certain percentage—I don't think 100%, but a certain percentage—with seaweed. So a few percent of seaweed plus a few percent of land plants plus trimmings—all that together—reduces the percentage.
