I'm not sure what the protocol is for using acoustic data to close or reopen a fishing area, but for sure we need to do the same thing for both actions, for closing it and reopening it. At the moment, acoustic detection works for detecting the presence of whales, but it's not used as a trigger to reopen an area when it's closed. That discrepancy might be problematic, yes.
