“…Effects of microplastics on fish are different based on their type (Choi et al 2018). The majority of plastic particles in this study were fibers and it was similar to the results of previous studies (Lusher et al 2013;Philips and Bonner 2015;Rummel et al 2016;Bellas et al 2016;Guven et al 2017;Peters et al 2017;Pazos et al 2017;Baalkhuyur et al 2018;Bessa et al 2018;McGoran et al 2018;Compa et al 2018;Horton et al 2018), followed by fragment (Bessa et al 2018;Compa et al 2018;Horton et al 2018) or hard plastic (Guven et al 2017), and film (Horton et al 2018). Type of ingested microplastic is related to the feeding behavior of examined fish.…”

“…So that in the same species, there was no correlation between the numbers of ingested microplastics, either total body weight or total body length. Some other previous studies found similar results that there was no correlation between the amount of ingested microplastic and either fish length (Alomar et al 2017;Guven et al 2017;Pazos et al 2017;Vendel et al 2017;Digka et al 2018;Horton et al 2018), sex (Guven et al 2017;Horton et al 2018), total body weight (Peters et al 2016;Guven et al 2017;Pazos et al 2017;Halstead et al 2018;Pegado et al 2018), feeding habit (Guven et al 2017;Pazos et al 2017), or trophic level (Guven et al 2017;Pegado et al 2018). Chen et al (2017) even found that larval body length was significantly reduced by 6% due to nanoplastic ingestion by zebrafish (Danio rerio).…”

“…However, Guven et al (2017) stated that the number of ingested microplastic was not influenced by trophic transfer. The density of microplastics in habitat may be the main factor of microplastic ingestion (Guven et al 2017;Pazos et al 2017;Markic et al 2018). Microplastics were higher in pelagic fishes than in demersal fishes whereas there was not significantly different (Lusher et al 2013;Rummel et al 2016;Guven et al 2017;McGoran et al 2018).…”

Abstract. Hastuti AR, Lumbanbatu DTF, Wardiatno Y. 2019. The presence of microplastics in the digestive tract of commercial fishes off Pantai Indah Kapuk coast, Jakarta, Indonesia. Biodiversitas 20: 1233-1242. Microplastics in fishes have been reported in many studies due to their threat to marine fishes and human health. But only a few data exist on commercial fish for human consumption in Indonesia. This study revealed the presence of microplastics in the digestive tract of 9 commercial species collected from six sites along the Pantai Indah Kapuk coast. Ingested microplastics were identified using gut content analysis. Microplastic particles were counted and categorized by type, color, and size. 169 of 174 (97.13%) of examined fish had microplastics. A total of 2063 microplastic particles were collected with the average number of particles per individual of 12.21 ± 9.76. The highest number (20.0 ± 8.0 particles individual-1) was found in Sardinella fimbriata and the lowest one (4.9 ± 4.7 particles individual-1) was found in Oreochromis mossambicus. Majority of ingested particles were fibers (89.63%), followed by fragments (6.24%), films (4.13%) and no pellets were observed. In terms of color, the most abundant were transparent particles (79.20%), followed by blue (7.03%), red (3.54%), black (2.86%), green (2.71%), and others which were found in low number. The highest number of fibers by size was <20-100 µm (55.03%), films were 100 - 1000 µm (33.93%), and fragments were <100 µm (25.25%). Microplastics ingested per individual in each species were not correlated to total body length, total body weight, digestive tract length, digestive content weight, mouth height, and mouth length.

“…The dominance of fibers as the most abundant MP type is well founded in the literature. Fibers constituted the greatest proportion of MPs in fish from the Río de la Plata estuary (96%) [47] and in the North Pacific Gyre (94%) [49] ATR-FTIR spectroscopy was used to verify the visual selection of MPs. All of the analyzed MPs (approximately 10% of the 211 recovered MPs) were plastic polymers.…”

The presence of microplastics (MPs) in the world’s longest river, the Nile River, has yet to be reported. This small-scale study aimed to provide the first information about MPs in the Nile River by sampling the digestive tracts of two fish species, the Nile tilapia (Oreochromis niloticus, n = 29) and catfish (Bagrus bayad, n = 14). Fish were purchased from local sellers in Cairo, and then their gastrointestinal tracts were dissected and examined for MPs. Over 75% of the fish sampled contained MPs in their digestive tract (MP prevalence of 75.9% and 78.6% for Nile tilapia and catfish, respectively). The most abundant MP type was fibers (65%), the next most abundant type was films (26.5%), and the remaining MPs were fragments. Polyethylene (PE), polyethylene terephthalate (PET) and polypropylene (PP) were all non-destructively identified by attenuated total reflectance Fourier transform infrared spectroscopy. A comparison with similar studies from marine and freshwater environments shows that this high level of MP ingestion is rarely found and that fish sampled from the Nile River in Cairo are potentially among the most in danger of consuming MPs worldwide. Further research needs to be conducted, but, in order to mitigate microplastic pollution in the Nile River, we must act now.

“…The source of pollution especially the emergence of fibres is believed to have originated from domestic or industrial discharge nearby. Meanwhile, recent studies reported by Pazos et al [31] and Güven et al [32] indicated that the emergence of a new contaminant affects the multispecies of fishes collected in estuary and coastal areas, respectively. Fibres become the prevalent type of microplastics found in both areas.…”

The presence of microplastics (<1 mm) in wild and cage-cultured Asian sea bass (Lates calcarifer) was successfully studied. Fish samples were collected from Setiu Wetlands in October 2016. Microplastics were isolated from fish samples using the alkaline solution method (10 M of NaOH solution). Microplastics were sorted visually according to their shapes and colours after being observed under dissecting microscope. A total of 4,498 pieces of microplastics were identified and threadlike shape was the most abundant microplastic particles found during this study. The identification of functional groups in the composition of microplastics was achieved using Fourier transform infrared (FTIR) spectroscopy. Microplastics, with the presence of strong peaks at ʋ=3342 cm -1 (N-H str), 1510 cm -1 (N-H bend) and ʋ=1706 cm -1 (C=O str) are associated with the materials consist of polyamide. Additionally, peaks related to the polyvinyl alcohol groups are recorded at ʋ= 3321 -4323 cm -1 (O-H str), 1706 cm -1 (C=O str), 1219 cm -1 (O-H wag) and ʋ=1028 -1128 cm -1 (C-O str). The abundance levels of microplastics ingested by wild and cage-cultured fishes are statistically significantly different, p <0.05.
