We've been using three science vessels, the Needler, the Templeman, and the Teleost. And whatever vessel we use, we have to calibrate the fishing tools to actually figure out how they compare. We used to use the Needler in the southern gulf; now we're using the Teleost. And there was a period of calibration.
We're expecting a new vessel in a couple of years. At that point in time, in order to ensure the time series, we will have to calibrate the tools as well. Even if we were to change the fishing gear, we would have to calibrate the old one with the new one, because you want to ensure that you're not managing noise; rather, you're managing a real fishing effort.
