Yes. I actually recently published a paper with George Rose on the northern cod stock. We examined the survey data and we've shown that the northern cod stock actually is rebuilding at a fairly high geometric rate, but it's still at such low numbers that it's going to be a long time before it reaches high biomass again.
DFO research in the Gulf of St. Lawrence indicates that seal predation impacts on the western-southern Gulf of St. Lawrence cod stock are probably very high, and have caused the natural mortality rate to be about four times higher than it should be.
