Maybe I'll fine-tune that point of view.
We have seasonal closures. When two whales are observed in the same area within a certain amount of time, they will close until November. They'll go through the season and close the area for the full year.
A lot of times no whales are seen. For instance, a week after the last sighting there were no whales, but we will still keep those areas closed for the full season. We're slowing down the fishery and are not actually protecting the whales.
For those kinds of things, optimization can be done to help.
