Table 1.  Listing of damage assessment from all turtle carcasses used in the trials. The “assess” column refers to whether the carcass should be used to assess carcass damage.   Carcass damage should only be assessed the first time a carcass is used. The “score of severity” refers to an evaluation of the damage incurred on the carcass. 1 = slight or none, 2 = moderate, 3 = severe.  Shading signifies carcasses that can be used for damage assessment.
