Obviously we have to obtain information relative to distribution, and past patterns of distribution are proving to be remarkably unreliable in today's environment. We're seeing fish move into areas where they haven't been in the past, and they're not in areas where they have been. We need to keep information current by having those sets take place.
That is one reason why we have sentinel fisheries, where you direct people on where to go. Even when the fishermen are fairly convinced--and most of the time, they are right--we still need to be able to ensure that we have credible information on the distribution.
Logbooks are one source, but with sentinel fisheries you get the catch over time, through a series of data. You also get the samples, etc., that you need. The test fishing on the west coast is absolutely essential.
