bobbernumber3: "Why do bass fishermen insist on weight as a measure? I have no idea what a six-pound fish looks like. How many inches... that I get." Probably because there are so many Bass tournaments especially in the south , and they go by total weight , a 6lb bass is about 21" maybe a hair longer. i generally weigh the nicer fish we catch. some fish can be deceive . this one surprised me last winter. just over 25" and came up 7lb-8oz thats generally a 27" to 27 1/2" walleye.

Looks to be right on for average fish. Fattys will weigh a little more, and the anorexic will weigh less.The laker chart does seem a bit heavy. I wish more people used these(or owned accurate scales). I hear some crazy tales about huge fish. There are WAY too many 5# smallys ,10# walleye, and 20# pike reported. Two years ago a guy who we met on Crooked was talking about all of the 5-6 lb smallmouth they were catching. He had one of the bigger ones on a stringer and when he showed it to me I knew it was not the 6 1\4 he claimed (MAYBE 4#). When I asked him if he measured it he said he had and it was 20 inches. Since it was NOT a fat fish I think his scales must have seen better days! Another fella told us he had caught over 100 smallmouth over 5# in 6 trips and his largest was about 8#. These guys need these charts!

Geo, I couldn't agree more about any legitimate trophy needing to be weighed on a scale. The key here as I stated in my previous post was that I have seen way too many fish weighed on inaccurate scales. I have a pile of scales at home both spring and digital that started weighing fish heavy. I check them regularly with certified weights.In both of the cases In my last post the guys HAD been weighing their fish, and were obviously off by a mile.I think that knowing a 7# smally needs to be around 24 inches or a 5# needing to be around 21.5 would help keep these guys honest or at least let people know when their scale needs to be replaced.In other words someone saying they know how much their fish weighed because they weighed it is completely meaningless unless you know the scale is accurate. Two different scales is a good idea.

Page down and present is some charts that I think are excellent length weight charts of many fish.


fish weight


Now like you know,fish from different waters will have different plumpness or condition factor. Off coarse your fish will always weight more? Right? I do know lake trout and smallmouth can weight maybe = or - 20%.


I like the lake trout and a few others and have printed them off for my personnel use. "



The only LEGITIMATE 5lb smallies up there are those put on a scale.


I have seen way too many 7lb smallies, based on the formulas.


No thanks. I take a digital scale, and buddy takes a digital scale. Any serious fish gets weighted on both.


Later,


Geo

That's a fatty for sure!

"



Don't know that I agree. I have a bunch of digitals that are WAY off, several high end scales. I have a Chatillon spring scale that is certifiable as well as a couple of Bogas that are also certifiable and always check right on when tested. Not too many digitals are, and the weights bounce around so much in waves it is hard getting an accurate reading and peak reading is always way heavy. They are getting better. If any scale gets rust or corrosion it will become inaccurate."
True, i found most digital scales (newer) to be within an ounce or 2 , i always check mine against something certified. always has been with in an ounce.

I agree, these are good charts. That makes a 30" walleye about 9#, a 40" pike about 15# and a 20" smallmouth about 4#. I'd say that is very consistent with my experiences in canoe country. My biggest BW lake trout have been in the 34-36" range and were not as heavy as the chart indicates.

There's a fill-in-the-blank calculator for the Ontario Angler awards program. Walleye and pike only need length entered, but bass and trout need girth as well, though the formulas are the same. (You could write down or memorize the formula for use on trips. e.g., Walleye = length cubed/2700) FISH WEIGHT CALCULATOR --Goose

Why do bass fishermen insist on weight as a measure? I have no idea what a six-pound fish looks like. How many inches... that I get.
