The degradation of coated, steel fish hooks exposed to simulated and actual sturgeon body fluid was evaluated using the mechanical methods of several grades of commercial fish hooks were examined using characteristic deformation and fracture strength through stress-strain curves. Most current research on fish hooks is done in tension. We developed a novel approach which involved designing a mounting method to better simulate the mechanical forces expected in a sturgeon gizzard. The mechanical properties are correlated with the degradation exposure and the nature of the coating materials.
