If only 2% of the bear taken are over 500lbs, then you best be prepared. Can't count on shooting a small one.
If you are hunting in Maine with an outfitter over bait, you are likely to take a 150lb cookie-cutter. We only take about 3000 bears a year so there are a lot more mature boars out there.
The average mahi mahi might be 2-5 pounds. But I'm not trolling offshore with 6lb test.
