The LDH could differ in fish that are fresh versus fish that are frozen. During the experiment test tubes were supposed to be placed in a beaker of ice, but if they were not that could affect your LDH results. When using a homogenizer, pieces of white muscle tissue can get caught in the end of it and if not cleaned after every use can contaminate the next test tube. If I did this experiment again, I would use species that have a habitat closely related to lizard-fish. Shrimp and croaker fish have similar habitats to lizard-fish, but are not always found in the same places. I would choose a species that closely resembles lizard-fish to see if the LDH activity was close to each
