"Fish, which have escaped from a cormorant's (Phalacrocorax carbo sinensis (L.) grasp and/or which could not be swallowed due to their size, suffer from various injuries resulting in consecutive infections and subsequent increased mortality. A computer assisted image analysis was applied to describe the extent of such injuries. Two-year-old mirror carp, Cyprinus carpio L. (TL 200 - 300 mm, W 200-300 g) showed injuries ranging over approximately 10% of the total body surface. Immediately after wounding, the damaged epithelium (scars) cover 5 - 35 %, and deeper sub-dermal wounds, caused by the beak tip pervading into muscle tissue, cover an area of 1- 2 % of the total body surface. On the side impacted by cormorant lower mandible, extensive areas of epidermal contusions (scars) occur. As the time progresses, these ratios change - deeper necroses represent up to 10 % of total body surface and healing epithelial scars comprise just 1 - 2 %.
