a 10 hour day equals 600 minutes. To catch 100 fish in a day that means you caught(cast, hook, reel in, un-hook, release) a fish on the average of every 6 minutes. Factor in pee breaks, getting hung up, retying lures, food/drink breaks, and that is almost an impossible task. If two guys are in the boat, then it is 12 minutes per fish(assuming each angler caught 50 each), which is still an incredible feat. Kudos to anyone that can accomplish it.
