We examined the occurrence of marine debris in the gastrointestinal tract of 54 loggerhead sea turtles (Caretta caretta) found stranded or incidentally captured dead by fisheries in the Adriatic Sea, with a curved carapace length of 25.0-79.2 cm. Marine debris was present in 35.2% of turtles and included soft plastic, ropes, Styrofoam and monofilament lines found in 68.4%, 42.1%, 15.8% and 5.3% of loggerheads that have ingested debris, respectively. The dry mass of debris per turtle was low, ranging from <0.01 to 0.71 g, and the ingestion was not significantly affected by sex or body size (all p>0.05). Marine debris averaged 2.2 ± 8.0% of dry mass of gut content, with a maximum of 35% found in a juvenile turtle that most likely died due to debris ingestion. Considering the relatively high occurrence of debris intake and possible sub-lethal effects of even small quantities of marine debris, this can be an additional factor of concern for loggerheads in the Adriatic Sea.
我们检查了在亚得里亚海被渔业搁浅或偶然捕获死亡的 54 只红海龟（Caretta caretta）的胃肠道中海洋碎片的发生情况，其弯曲甲壳长度为 25.0-79.2 厘米。在 35.2%的海龟中发现了海洋碎片，包括软塑料、绳索、泡沫塑料和单丝线，分别在摄入碎片的海龟中发现了 68.4%、42.1%、15.8%和 5.3%。每只海龟的碎片干质量较低，范围为<0.01 至 0.71 克，并且性别或体型大小对摄入碎片的影响不显著（所有 p>0.05）。海洋碎片平均占肠道内容物干质量的 2.2±8.0%，在一只幼龟中发现的最大比例为 35%，这只幼龟很可能因摄入碎片而死亡。考虑到摄入碎片的相对较高发生率，以及即使是少量海洋碎片可能产生的亚致死影响，这可能是亚得里亚海红海龟的另一个关注因素。
