Certainly, in the Newfoundland and Labrador context, and I believe also in other regions, fishing enterprises tend to be multi-species, which means they can fish groundfish, shellfish, pelagics, etc. Not all of those fisheries are individual quota fisheries, so in some instances, a harvester who will have access to crab, for example, with an IQ—you're absolutely right—would be limited by the amount of fish associated with that, but they could then potentially use that same vessel to fish in a competitive fishery for which there is no individual limit.
In that instance, a larger vessel would put that individual participant at a distinct competitive advantage against other participants who are not using the same size vessel. Further, there have been some concerns expressed about competition, even in IQ fisheries, because a larger vessel is able to carry more gear and is able to fish in potentially more challenging environmental conditions, thereby perhaps having competitive access to preferential grounds. Not only is competition an issue in competitive fisheries, but there are also some competitive advantages that a larger vessel would confer over a smaller vessel.
