We have a number of things that we use. We go with landing slips, and then there are mandatory log books and we ask people to record what they're catching.
I'll highlight one other thing, which we do with the FSRS, the Fishermen Scientist Research Society. We provide a number of fish—I think it's 180 or something like that across Atlantic Canada—with two to five extra traps each, and we make those different types of traps so they capture everything. We can actually look to see how many smaller lobster there are. We do all kinds of tests on them: we tag them and check the eggs, the gender, the length, the number of V-notches, etc. That has actually been enormously useful, because the challenge with only working with the commercial fishermen is that you only get the legal sized lobsters. That tells you what that subset is, but now we have this other piece that gives us a broader sense.
Also, we do vessel-based surveys in a number of areas that catch lobster as bycatch, and we use that information as well. So we do have information coming from a number of sources as well as some of the pure research.
