The fracture energy of a material can be calculated using an impact test. The opercles the great sculpin (Myoxocephalus polyacanthocephalus) and Chinook salmon (Oncorhynchus tshawytscha) were dissected, cut into uniform sizes with a laser, and subjected to a Chapry Impact test. The cross sectional areas of broken samples were used to calculate the fracture energy of the material. The mean of the nobone trials was 0.8124 m with a standard deviation of 0.00176. . Maximum and minimum values for fracture energy of acellular bone were 2877.63 J/cm2 and 1940.308 J/cm2, respectively. Maximum and minimum values for fracture energy of cellular were 2643.25 J/cm2 and 1663.49 J/cm2, respectively. The fracture energies of the acellular and cellular bone were not significantly different (p=0.3483).en-USAcellular, Cellular, Bone, Impact Test, Pendulum, Fracture EnergyOther
