Freshwater fish weight calculators for Largemouth Bass, Muskie, Pike, Walleye, and Trout. The weight results will be extremely close to the actual weight of the fish. At the bottom of the page is a saltwater fish calculator for big game fish such as Marlin, Swordfish, Wahoo etc.
For some saltwater fish such as Grouper you will get a closer weight calulation by using a freshwater fishing calculator for the freshwater fish that most closely resembles the body dimensions of the saltwater fish you want a weight for. In this case a Grouper would resemble the body style of a Largemouth Bass even though a Grouper can grow much larger.
