Our fishing team this year entered our first derby, it was the fall LOC. We caught a 31.14 pound king and it got us a 10th place finish. We were 11th but for whatever reason we ended up 10th. Anyway, after we caught it, we fished another hour or so. Was that bad? We filled the cooler with water and by the time we got it to a scale it was about an hour and a half later. We didn't think it was as big as it was so we kept fishing. People tell me that a fish looses weight after it is caught. Is that true and if it is how much and how fast.
