Formulas for detemining approximate weight by using length and girth:

This is and approximate weight based on measurements it is not exact!  

Length (L), Girth (G), Fish Type Factor (FT)

If a girth is not taken the default value Fish Girth = 0.58 x L

• Trout, Steelhead     Weight= L x G x G / FT-900
• Salmon     Weight= L x G x G / FT-800
• Redfish     Weight= Lx G x G / FT-800
• Sunfish, Bluegill, Rock Bass     Weight= L x L x L / FT-1200
• Bass     Weight= L x L x G / FT-1200
• Bluefish     Weight= L x G x G / FT-900
• Pike     Weight= L x L x L / FT-3500
• Striped Bass     Weight= L x L x L / FT-2200
• Walleye     Weight= L x L x L / FT-2700
