What's biting
Not enough anglers have shared catches here lately. A species shows for a week once at least 5 anglers share catches of it.
From anglers who chose to share their catches in HuntGrid Fishing, each counted once, counts rounded to the nearest 5, published 3 days after the week ends and never changed. Never a spot, time or name.
