"Cormorants grasp prey fish by sharp tip of the beak with the tendency to hit the proximal body area behind gill cover (operculum). They emerge with the prey on water surface before swallowing it head forwards. Fish, which escaped from cormorant\u00B4s grasp and/or which could not be swallowed due to their big size, suffer from various deep injuries resulting in consecutive infections and subsequent mortality. The computer assisted image analysis was applied to describe the time dependent course of injury infection and progress. Two-year-old mirror carp ( 250 mm TL, 200 g W) which escaped from cormorant\u00B4s beak grasp had injuries ranging over approximately 10% of the total body surface. Immediately after wounding, the damaged epithelium makes about 8 %, and deeper under-epithelial wounds caused by beak tip represent the area of 1- 2 % of the total body surface. With the time progress, these ratios change - deeper necroses represent up to 10 % body surface and healing epithelium makes just 1 - 2 %. Major par"@en . "516131" . "2"^^ . "3"^^ .
