“…Coherent to this study, previous studies employing fish from Mugilidae family also reported the dominance of fiber particles in the GIT (Naidoo et al, 2016;Güven et al, 2017;Jabeen et al, 2017;Cheung et al, 2018;Halstead et al, 2018;Hastuti et al, 2019;McGregor & Strydom, 2020;Zhang et al, 2021b;Guilhermino et al, 2021;Saha et al, 2021;Nematollahi et al, 2021;Wootton et al, 2021;Kılıç & Yücel, 2022) The size of MPs is the main factor determining the ingestion potential of a particle. In fact, as the size of a MPs decreases, its bioavailability to the marine biota increases (Shim et al, 2018).…”

“…As a consequence of global microplastic pollution concern, a significant number of studies have been devoted to monitor microplastic pollution in the marine ecosystem and its interaction with marine biota. In this context, species belonging to the Mugilidae family were proposed as bioindicator species which might be used to understand both MPs pollution level in the sampling area and potential harm to the marine biota (Naidoo et al, 2016;Zhang et al, 2021b;Wootton et al, 2021;Reboa et al, 2022;Kılıç & Yücel, 2022). This study was designed to evaluate microplastic occurrence in the gill and GIT of Mugilidae (Chelon ramada) in the heavily urbanized region, İskenderun Bay.…”

Microplastic pollution in marine ecosystems has become a significant, global concern which attracting the attention of academics and policy makers. This study provides information regarding the microplastic occurrence in the gill and gastrointestinal tract (GIT) of Chelon ramada (Risso, 1827). A total of 158 MPs were extracted from the gill and GIT with a mean of 1.9±1.8 particle/individual in gill and 3.4±2.1 particle/individual in GIT. Fiber was the most commonly extracted microplastic type (79%), followed by fragments (16%), film (4%) and pellet (2%). Mean size of extracted MPs from the organs of Chelon ramada was found as 1251±1602 µm. Black, transparent, red and blue MPs were extracted from the organs and dominance of black and transparent MPs were observed in the gill and GIT, respectively. This study is providing the first data regarding the microplastic ingestion of Chelon ramada and the results obtained in this will help to understand the relationship between anthropogenic influences and microplastic ingestion.

“…This study provided the first published characterization record of microplastics by FT-IR in the gastrointestinal tract and gills in both pelagic and demersal fish in the eastern coastal water of Thailand. The proportion of fish to have ingested plastics (13%) was less than those recorded by [25], showing 36.5% of 504 fishes (five demersal and five pelagic species) from the English Channel, 33% of 122 catfish from Brazil [51], 35.5% of commercially caught fish across southern Australia [28], 33% of six fish species of commercial importance in central Chile [52], and 85.4% of 29 of the commercial fish species from the Bohai Sea in China [53]. However, results of this study presented a higher frequency of microplastic in fish found compared to other areas of Thai water [39].…”

“…Due to their characteristics (i.e., buoyancy, colors, sizes, and shapes), some plastic particles in the water column or on the seafloor may appear physically as natural food sources, resulting in accidental ingestion by fish [25,26]. Therefore, the ingestion of microplastics in aquatic organisms is of concern due to the physical and chemical harm to their bodies [27][28][29][30]. MPs can also be found in the food web, either in zooplankton or in the higher ingestion hierarchy and food supply, such as in humans [31][32][33].…”

Marine microplastic has been in the limelight recently. This study aimed to describe microplastic types ingested by 274 fish from Thailand’s eastern coast in 2020 and to compare the microplastic content among different feeding traits. The microplastics in the gastrointestinal tracts and gills were extracted, analyzed, and identified using FT-IR spectroscopy. Approximately 13.14% of the total specimen ingested microplastics, with an average of 0.14 items per individual. The detection frequency of microplastics was relatively high compared with other regions in Thailand but relatively low compared to global standards. Of the microplastic contaminated specimens, 56.41% had at least one piece of microplastic in their gastrointestinal tract. Pelagic (14.47%) species were found to have ingested more microplastics than the demersal (12.63%) group. Dominant aspects found included PET (as in polymers), fiber (as in shape), and black (as in color). However, microplastic numbers fluctuated with the size, weight, and feeding behavior of fish. This result suggested that the pelagic has a higher exposure risk and microplastic ingestion in relatively small quantities in a range of fish species. Our results indicated that the occurrence of microplastics in fish is not influenced by organism habitat or trophic level, although the characteristics of pelagic fish might significantly increase the chance of exposure to microplastics in pelagic species.

“…There exists a critical knowledge gap on the potential MP transfer to Australian consumers, which is of particular concern as many crustaceans are low-trophic-level scavengers or filter feeders and may be at higher risk of MP contamination [ 53 ]. Wooton et al [ 54 ] assessed the abundance of MPs from common commercial fishes, such as goatfish, sea mullet, paddle tail, and common coral trout, from Fiji and Australian fish markets. They reported that the MPs were more prominent in the fishes from Australia (61.6%) than Fiji (35.3%), with an average of 1.58 ± 0.23 pieces/fish and 0.86 ± 0.14 pieces/fish, respectively.…”

While plastics are already notorious for their accumulation in the environment, which poses environmental challenges, invisible microplastics (MPS) are an even greater challenge. This review focuses on consolidating the reports available on MP accumulation in edible marine and freshwater fishes, shrimps, and crabs. The reality as to whether MPs in these edible aquatic organisms are really a cause of high concern is questioned and discussed. While the entrails of aquatic organisms are reported to contain high levels of MPs, because these products are consumed after the removal of the entrails and gut area in the majority of cases, the MP threat is questionable. The existence of MPs in these aquatic sources is validated but their potency in harming humans, aquatic organisms, and other interlinked species is unassessed. To overcome the difficulty in tracing the movement of MPs in a bigger ecosystem, this review proposes laboratory-based pilot studies mimicking real-world conditions, which will help us to understand the kinetics of MPs in the food chain. The effects of MPs on human welfare and health are yet to be assessed, and this is another gap that needs attention.
