Thank you for the question.
Logbooks for bait fisheries are indeed mandatory, and data is being reported. However, the data isn't considered very reliable, which could affect the confidence interval that you mentioned earlier.
We don't think that we're getting many logbooks. We do follow up, but it's almost impossible to check when a fisherman picks up their bait nets, since they often do so on a lobster fishing trip. It's impossible to ensure that all landings are reported. It depends on how the fishery is managed.
