“…All examined samples in this study were adult fishes. Ferreira et al (2018) found that adult fishes had the most contaminated ontogenetic phase; they ingested almost all organisms whose guts have been contaminated with microplastics. Ramos et al (2012) also found that the higher number of microplastics were in adult, subadult, and juvenile phase respectively.…”

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.

“…Ingestion of microplastics by fish can be affected by their feeding habits. Filter-feeding fish can ingest microplastics during filtration (Fossi et al, 2014) while trophic transfer and initiative predation are both potential pathways for microplastics to enter predators and opportunistic feeders (Ferreira et al, 2018;Grigorakis et al, 2017;Lu et al, 2016;Ory et al, 2018). In finless porpoise, unintentional ingestion of microplastics has been speculated as the avenue for microplastics found in neonatal porpoise (Xiong et al, 2018).…”

It is vital to understand processes of microplastic ingestion and egestion by aquatic organisms in order to evaluate the potential effects and impacts of microplastics in aquatic ecosystems. In this study, goldfish (Carassius auratus) was used to investigate ingestion and egestion of polyethylene (PE) microplastics and how these processes were affected by size, color, and shape of microplastics. Results showed that goldfish ingested white PE microplastics only in the presence of fish feed and that microplastics larger than 2 mm were rejected even after being ingested. However, in the presence of food, more green and black microplastics were ingested compared with red, blue, and white microplastics while significantly higher amounts of microplastic films were ingested compared with fragments and filaments. Microplastics ingested by goldfish were egested within 72 h. However, the egestion rate of filaments was the lowest among all tested microplastic shapes. The presence of food appeared to reduce film and filament residues in fish after 72 h. Results of this study imply that different features of microplastics result in different exposure risks for fish. Thus, the specific features of microplastics (e.g. their shape, color, and size) should be considered in future ecotoxicological studies.

“…Observations of bait-fi sh gut contents at St. Helena showed that they have also ingested plastic. Our work shows a worrying state of the environment in these proposed and new MPAs, where plastics are now entering the food chain, as already seen elsewhere [2,7,8]. Policy needs to catch up with high and escalating risks from plastic pollution.…”

“…Inshore zooplankton entanglement in microplastics varied from 1.8-48.7 zooplankton m -3 . Recent literature has highlighted this bioaccumulation threat for giant plankton feeders such as rays and whalesharks [2,7]. Around St. Helena they are prominent ecosystem components -iconic and key targets for regional conservation.…”
