Diet composition of loggerhead sea turtle Caretta caretta in the Adriatic Sea
We performed a general necropsy on 54 loggerhead turtles with CCLn-t = 25.0 – 70.0 cm (mean: 40.9 cm, SD: 9.1) found dead-stranded or incidentally captured dead by fisheries in the eastern Adriatic Sea (Croatia and Slovenia), and isolated digestive tract content by rinsing through a fine-mesh sieve. Food item samples were later identified and wet weighed for each identified taxon. Total wet weight (w.w.) of individual samples ranged from 0.29 to 959.46 g (mean: 198.6, SD: 202.2). The following taxa were recorded: Porifera, Anthozoa, Scyphozoa, Sipuncula, Gastropoda and Bivalvia, Cephalopoda, Polychaeta, Crustacea, Insecta, Bryozoa, Ophiuroidea, Echinoidea, Tunicata, Pisces, Algae and Spermatophyta. Three highly ranked prey groups included Crustacea (26.6%), Anthozoa (25.7% w.w.) and Mollusca (Gastropoda and Bivalvia, 22.3%) whilst all other taxa accounted for 25.4% w.w. These three taxa also had the highest occurrence (92.6, 61.1 and 94.4%, respectively), and present the most important prey in diet of loggerheads in the Adriatic Sea.
