With regards to regulation changes, you're in the worst possible spot. You have to make potentially unpopular decisions based on what information you may or may not have, yet you want to keep fishermen happy and be able to fish yourself. I know how it feels and I don't envy your position. However, I do have a suggestion.

Perhaps someone could take the time to cut and paste or write up a detailed explaination specifically for this proposed regulation change. The information must exist in a report or a group or reports. It would be very interesting and informative to see what the data are saying that drive managers to make decisions. I'm sure to even think about drafting regulation changes, there has to be substantial justification backed by real data.
