    Ontario's current Fishing Regulations Summary lists the Nipigon River and Lake Nipigon under FMZ 6, where pike is open all year. This pack's existing brook_trout entry is tagged FMZ 9 — flagging that zone-assignment discrepancy for follow-up rather than silently resolving it; verify both zone tags against the current Ontario Fishing Regulations Summary.
