You're very right on that. There are a number of invertebrate fisheries that have been around for a while. Lobster is one fishery, but there are others that have been newly developed as a response to declining traditional groundfish fisheries mostly. So these are things like sea cucumbers, sea urchins, snow crabs, rock crabs, other crabs. Hagfish is another species that has been newly developed. Those mainly started in the eighties. For a number of these fisheries, I have a student who looked into seven stocks that have only 20% of the population knowledge factors that you need to do a proper scientific stock assessment, which we do for most finfish species. There is some knowledge on the fishery and how much is caught, but the basic biomass, like how much is out there, where are these species, how do they respond to exploitation, is often lacking.
I just compared the research documents on the sea cucumber fisheries for the west coast and the east coast, and they have both been around for roughly ten years. The west coast has 160 pages, very detailed, good knowledge, a good assessment. The east coast has 30 pages, but it reads mostly as we don't know this, we don't know this, we don't know this. So it's very risky.
