The long-distance migrations we hear about are mostly for very large species that undergo very long migrations. Tuna, being one of them, crosses the Atlantic on a regular basis a couple of times a year. Most of the stocks we deal with in this region, cod, flatfish, and capelin, will undertake migrations that may be on the order of several thousands of kilometres, but they won't necessarily cross the ocean, per se.
We've seen very little evidence that the cod stock in our region, for instance, actually influences anything we see in Greenland. Along our shelf, from Labrador to here, we do see those kinds of interactions. We do see that kind of migration. But for most of the species, the migrations are a little bit more restrained, and the broad-scale dispersal from one country to the next tends to be very close to the boundary most of the time.
