Abstract:

Observations of investigations for plastic ingestion in loggerhead turtles (Caretta caretta), stranded or bycaught on the coastline of North Cyprus (Eastern Mediterranean). A total of 135 loggerhead turtles were sampled spanning a period of 11 years (2012-2022). During necropsy, the entire gastrointestinal tract was removed and initial contents weighed. The contents were grossly examined then rinsed through a 1 mm mesh sieve to separate and remove the plastic for classification and dietary items for storage and analysis. Ingested plastic was classified using a system outlined in Duncan et al. (2019, doi:10.1038/s41598-019-48086-4; 2021, doi:10.3389/fmars.2021.699521) which builds upon the Fulmar Protocol and MSFD (Marine Strategy Framework Directive) Marine Litter Report 2011 (Descriptor 10) toolkits (Galgani et al., 2014, doi:10.1016/j.marenvres.2014.02.003; van Franeker et al., 2011, doi:10.1016/j.envpol.2011.06.008).
