“…In the rivers, once fragmented into smaller particles, these polymers can be ingested, intentionally or accidentally, by many animals, especially the ichthyofauna (Lusher et al 2013, Cardozo et al 2018, Azevedo-Santos et al 2019. In Brazil, the presence of plastic in the digestive tract of fish was first recorded in estuarine ecosystems (Possatto et al 2011, Dantas et al 2012, Ramos et al 2012 and then in freshwater ones (Silva-Cavalcanti et al 2017.…”

This is the first study to report the plastic ingestion by Prochilodus lineatus in Brazilian fluvial ecosystems. We examined 32 individuals collected in two contrasting lotic environments: the highly polluted Tietê River and its much less degraded tributary, Peixe River. Most individuals, 71.88%, contained plastic in their digestive tract, with averages of 3.26 and 9.37 particles per individual in the tributary and main river, respectively. The blue color was predominant among the observed plastic particles and size ranged from 0.18 to 12.35 mm. Plastic ingestion must be accidental, predominantly, since the species has an iliophagous eating habit. As this species is regionally the most important fishery resource, potential adverse effects of this type of contamination may be transferred to human consuming populations. Mitigation measures against pollution are urgent in the Tietê River basin.

“…Also, this issue has the potential of negatively affecting commercial fishing (Possatto et al, 2011;Foekema et al, 2013). The direct and indirect impacts of plastic ingestion, such as false satiation and blockage of the digestive tract can also be sources of disturbance in life story traits and general health condition of crustaceans (Watts et al, 2015;Welden and Cowie, 2016;Bordbar et al, 2018;Jabeen et al, 2018), as well as in other groups of organisms (Lavers, 2016;Cardozo et al, 2018;Clukey et al, 2018;Forrest and Hindell, 2018).…”

The aim of this study was to investigate the plastic consumption by the rocky shore crab Pachygrapsus transversus and its effects in the species feeding activity. Specimens were collected monthly from August 2019 to January 2020 in a coral reef located in the north-eastern Brazilian coast, taken to the research laboratory, where they had their stomach removed, degree of fullness determined for each stomach and presence/absence of plastic debris assessed. Frequencies of occurrence of each degree of fullness were compared between sexes and contaminated/non-contaminated individuals. At total, 209 specimens were sampled and high levels of plastic contamination were detected: 47.4% of the sample had plastic fibres in the foregut. All contamination consisted only of nylon filaments, suggesting that irregularly discarded fishing equipment is the source. The frequencies of contaminated individuals among sexes did not differ. However, differences were detected in the comparison between degrees of fullness, demonstrating that there is significant influence of plastic ingestion in the stomachs volume. It is possible that the discrepant frequencies of occurrence of gut fullness were due to false satiation effects and blockage of the digestive tract provided by the fibres.

“…This is likely a consequence of higher microfilaments availability, coinciding with the peak in the fishing activity in the estuary 7 . Indeed, fishes are regularly reported with microfilament contamination that originates from fishing gear 44,50,51 .…”

The dynamics of microfilament (<5 mm) ingestion were evaluated in three species of snooks. The ingestion of different colours and sizes of microfilaments were strongly associated with the spatio-temporal estuarine use and ontogenetic shifts of snooks. Their feeding ecology was also analysed to assess dietary relationships with patterns of contamination. All species were highly contaminated with microfilaments. The highest ingestion of microfilaments occurred in the adults, when fishes became the main prey item and also during the peak of fishing activities, in the rainy season. This suggests that trophic transfer, in addition to periods of high availability of microfilaments are important pathways for contamination. The ingestion of microfilaments of different colours and sizes was likely influenced by input sources. Blue microfilaments were frequently ingested, and appear to have both riverine and estuarine inputs, since they were ingested in all seasons and habitats. Purple and red microfilaments were more frequently ingested in the lower estuarine habitats. The length of microfilaments was also associated with environmental variability. Longer microfilaments were ingested in habitats with greater riverine influence, the opposite was observed for shorter microfilaments. Therefore, microfilament contamination in snooks are a consequence of their ecological patterns of estuarine uses through different seasons and life history stages.
