Any ideas why mission and echo perch are light for their length. Last year on first ice I caught a 14.5" perch and it only waighed in at 1.3lbs! THat one I know was sick, fairly skinny and skagily, but this year again caught 13.5"- went 1.3, and echo a 13 1/8" went 1.2 I know a guy caught a 13 1/2" at barrier and went 1lb10oz. Echo guy I know caught a 14" last weekend and I weighed with my digital- 1.4lbs, +.1lb for water loss- still only 1.5lbs for a 14"! whats going on?
