These measures already exist. For example, places that are 20 fathoms deep or less are the best places for lobster fishing. Those measures are not really the same as the measures established for places that are 20 fathoms deep or more.
I am sure that some of my colleagues will be better able to inform you than I am about these measures, because they are people engaged in lobster fishing. That is actually one of the good options that the department chose, to show that, in fact, they can be flexible in managing these measures. It is an example that works.
