Here is a link to some good standard weight tables for various species of sport fish. Thanks to good efforts by a Pond Boss Forum member: DNickolaus. Tables are especially good because they include smaller sizes of the fish.

I see that the post I made many years ago linking to some great relative weight (Wr) charts is no longer available at those links.
These old links NOW DO NOT WORK: Weight Length Chart 1 of 3 -- BG, PS, CP, BC, WC, RBS, YP & WE Weight-Length Chart 2 of 3 -- Muski, NP, Am. Shad, Brown-Rainbow-Brook Trout. Weight-Length Chart 3 of 3 -- LMB, SMB, SB, CC & Brown Bullheads Regards,

3-26-2023 Note: These links are no longer working. I am trying to dig them up and save them to my computer, THEN post them here. I should be able to do that if I can figure out how to convert a PDF file to a JPG image. Look below, I was able to do it.
Thank you Ken!! I was sorry to see them disappear. Glad to have them back!!
Here is relative weight calculator from Univ Alabama for some common pond fish.
