“…Thus our findings of increased plastic abundance during the wet season are supported by the seasonal increase in regional river pollution emissions. Similar findings from the other side of the world indicate that the increase in rainfall during the hurricane season in Banderas Bay, Mexico also likely leads to an increase in the contribution of plastic debris from land-based sources via river emissions (Pelamatti et al, 2019).…”

“…Even with these higher estimates, we are likely to be underestimating the amount of plastic intake, as our abundance estimates are limited to free-floating plastics and do not include any plastics ingested by plankton (Cole et al, 2013;Setälä et al, 2014). Plastic levels have not been characterized in many other manta ray (Pelamatti et al, 2019) and whale shark feeding grounds, but despite this general lack of comparisons, we think that large filterfeeders in Indonesia are likely to be feeding in more heavily polluted waters than most other locations throughout their range (Germanov et al, 2018).…”

“…The durability of plastic items, and the distance and time taken to 'arrive' at the sampling locations, as well as the rates of vertical migrations through biofouling, might explain the differences in the plastic 'signatures' of the different locations that we investigated (e.g., more hard plastic fragments in KM than MB). Follow-up studies characterizing the polymers types present in the microplastics can help link the plastic debris to consumer goods and help to identify their origin (Rios et al, 2010;Reisser et al, 2013;Pedrotti et al, 2016;Pelamatti et al, 2019).…”

Microplastics in Indonesian Megafauna Habitats ray egested material confirmed plastic ingestion, the consequences of which might include exposure to toxic plastic additives and adhered persistent organic pollutants. Communicating this information to communities who stand to benefit from healthy megafauna populations might help local governments as they work toward reducing plastics in the marine environment.

During rainy season, a various type of litter can enter the ocean through rivers. This is a significant contributor to the amount of marine litter in the waters. In order to access the type, composition, and density of the litter during rainy season, this study was conducted in Manado Bay, North Sulawesi. The observation was done on the litter stranded on the beach, and they were classified into two different size groups, macro (>2,5 cm)- and meso (0,5-2,5 cm)-sizes. Malalayang Beach and Bailang Beach were chosen for the location of the study. Litter type, composition, and density was evaluated according to National Marine Litter Monitoring Guide. The result showed that there were 7 types of macro-size and 6 types of meso-size marine litter in Malalayang Beach and it was dominated by glass and ceramic for both sizes. In Bailang Beach, 9 types of macro-size and 7 of meso-size were found, and it was dominated by plastics. It can be concluded that various type of marine litter present in Manado Bay, both macro- and meso- sizes, during the rainy season. The highest composition was the glass and ceramics type. However, the highest density was the plastic type.---Pada musim hujan, berbagai jenis sampah dari daratan masuk ke perairan pantai melalui sungai. Hal ini merupakan penyumbang signifikan bagi jumlah sampah laut di perairan. Untuk menilai jenis bahan, komposisi, dan kepadatan sampah laut pada musim hujan, penelitian ini dilakukan di Teluk Manado, Sulawesi Bagian Utara. Pengamatan dilakukan terhadap sampah laut yang terdampar di pantai (beach litter), berukuran makro (> 2,5 cm) dan meso (0,5-2,5 cm), di dua lokasi, yaitu Pantai Malalayang dan Pantai Bailang. Sampah laut dievaluasi menggunakan Pedoman Nasional tentang Pemantauan Sampah Pantai. Hasil penelitian menunjukkan, sampah laut jenis plastik, kaca & keramik, busa plastik, kertas & kardus, logam, karet, kayu, kain, dan bahan lainnya, baik berukuran makro maupun meso ditemukan di perairan. Di Pantai Bailang, komposisi sampah laut berukuran makro dan meso didominasi oleh jenis bahan plastik; tetapi, di Pantai Malalayang didominasi oleh jenis kaca & keramik. Demikian juga untuk kepadatan sampah laut di Pantai Bailang, jenis bahan plastik mendominasi, baik sampah berukuran makro maupun meso. Sedangkan di Pantai Malalayang, jenis kaca & keramik mendominasi kepadatan sampah laut pada semua ukuran. Selanjutnya, dapat disimpulkan, pada musim hujan, berbagai jenis bahan sampah laut berada di Teluk Manado, baik berukuran makro maupun meso. Komposisi terbesar untuk ukuran makro dan meso ialah jenis bahan kaca & keramik. Namun, kepadatan tertinggi untuk ukuran makro dan meso ialah sampah jenis bahan plastik.

“…Indonesia contributes to about 14% of the global annual plastic pollution in the marine environment (Lebreton et al 2017; Germanov et al 2019) with highest input recorded during the wet season compared to the dry one(Germanov et al 2019). Similarly, a signi cant quantity of plastics debris is also found in a similar foraging area Bahia de Banderas, Mexico, during the wet season due to river inputs(Pelamatti et al 2019).…”

Abundance and typology of microplastics (MPs) were measured in 12 water samples collected from two whale sharks feeding areas of the Gulf of California (Bahía de los Angeles (BLA) and Bahia de La Paz (LAP)). The concentration of MPs was 0.47 MPs/ m3 in BLA and 0.63 MPs/ m3 in LAP. Overall, films were the most abundant type of MPs (41%; n = 74) followed by line (37%; n = 68), fragments (20%; n = 36) and pellet (2%; n = 3), with significative differences between the types of microplastics. Theoretical ingestion rate per hour of MPs for the species was determined to be 288.58 and 386.82 in BLA and LAP, respectively. In faecal samples collected directly from animals of LAP (n = 3), 67% of the MPs were films, 25% were fragments, and 8% were lines. Results from this study indicate that MPs are common in the feeding areas of this endangered species and that whale sharks are likely ingesting MPs from filtering the surface water.
