Use A Ruler To Weigh Your Fish (2024)

For panfish, bass, trout, pike, muskie and walleye

Yes, it is possible to get an approximate weight for many species of fish by measuring their lengths. To estimate the weight of your catch, measure the fish's total length - from tail to the mouth - then refer to the appropriate table below. The weights listed are based on averages of each fish species measured across New York State. For assistance in identification of your catch, obtain a reliable field guide or check out DEC's "Freshwater Fishes of New York".

Remember, if you wish to practice catch and release, a fish's length can be quickly marked on your fishing rod, landing net, boat seat, or any handy object that can be measured later when a ruler is available.
