Plastic Particles in the Gastrointestinal Tract of Some Commercial Fish Species Inhabiting in the Gulf of Bejaia, Algeria
Summary
Researchers documented plastic particle ingestion in six commercial fish species from the Gulf of Bejaia, Algeria, finding plastic in 58.63% of 249 examined fish gastrointestinal tracts with an average of 8.45 items per fish, predominantly blue and red fibers across demersal, benthopelagic, and pelagic species.
In the present study we report for the first time, the presence of plastic particles on the gastrointestinal tracts of the examined commercial fish species: Sardinella aurita (n=60), Sardina pilchardus (n=60), Pagellus acarne (n=45), Trachurus trachurus (n=38), Boops boops (n=40), Sparus aurata (n=6).The sampled fish species (n=249) inhabiting in demersal, benthopelagic and pelagic marine ecosystems (Gulf of Bejaia) were examined to test eventual differences in micro and macro plastic particles.Overall, results showed that 58.63% of gastrointestinal tracts were contained plastic particles.An average 8.45 ± 14.69 items per fish were recorded.The most common morphotype particles were fiber (85%) whereas dominant colors of plastic debris were the blue and the red among three types of particle colors.Our results shows that are no significant differences between females and males specimens in terms of ingested plastic particles.The highest abundance of plastic particles in fish gastrointestinal tracts was recorded in wet season.
