“…However, in other cases, riverine (Andrade et al 2019) and estuarine (Vendel et al 2017) fish had no differences among functional groups. In ecosystems where there is more movement across habitats, such as within an estuary, variation in exposure and consumption may obscure the potential role of feeding guild on microplastic ingestion (Ferreira et al 2019). Differences among feeding guilds was indicated in cases when prevalence of microplastics was high (such as with 100% in our study and 99% in Mizraji et al 2017).…”

“…It is unclear whether the wide range reported for the prevalence of microplastics is due to ecological (riverine vs. lacustrine), watershed land-use, or cultural differences. Ontogenic diet shifts have not been substantially explored in fishes but have been found to influence fish microplastic concentrations in estuaries (e.g., Ferreira et al 2019). Fish −1 ) compared to those reported in other freshwater research (e.g., up to 20 No.…”

“…Studies of microplastic concentrations in fish have been conducted primarily in marine systems (de Sá et al 2018), and far less is understood about fish microplastic concentrations in freshwater systems, particularly lacustrine systems. Trophic level differences have been noted in marine (e.g., Nelms et al 2018) and estuarine (e.g., Ferreira et al 2019) systems, with varying amounts of microplastics in different fish tissues (Su et al 2019). In a study of freshwater fish in three tributaries to Lake Michigan, ecological and morphological traits corresponded with microplastic abundance in gastrointestinal tissues, indicating that functional feeding group might influence microplastic consumption (McNeiush et al 2018).…”

The emergence of microplastics as a potential contaminant requires understanding the distribution and potential consumption of microplastics across ecosystems and species. Freshwater environments are known to have high concentrations of microplastics, but very little is known about the concentrations of microplastics within lacustrine fish. The very high prevalence and numbers of microplastics in two fish species in agricultural reservoirs in this study indicates that lacustrine fish may be at high risk of microplastic contamination. AbstractMicroplastics in the environment can impact feeding and physiological functions of organisms. Most studies have focused on marine systems, and studies of lacustrine organisms are less common. We examined microplastic concentration in 72 gizzard shad and 24 largemouth bass from two agricultural reservoirs in the midwestern U.S.A. with differing shoreline development. Microplastics were found in 100% of the fish, with 1-49 No. Fish −1 , independent of shoreline development. Bass had higher concentrations overall than shad. For bass, microplastics were more concentrated in the guts rather than gills, but the opposite was the case for shad, suggesting that feeding guild may influence where microplastics accumulate in fishes. The prevalence and concentrations reported here are greater than reported in marine systems and higher than reported in riverine studies. Our results underscore the ubiquitous distribution of microplastics and suggest that lake ecosystems in agricultural landscapes may be particularly susceptible to microplastic contamination.

“…Snooks (Centropomidae) are one of the most important living resources exploited by American coastal fisheries, with annual landings of ≈ 13,000 tons on the east side of the continents 23 . Adult snooks are usually found in the outermost portion of the estuary 24 but also use habitats with greater structural complexity and migrate towards the inner habitats of the estuary in search of food and shelter 25 . Earlier stages are usually associated with nursery grounds in the mangrove creeks and upper estuary 24,26 .…”

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.

Microplastics (MPs) have attracted global concern because of their harmful effects on marine biota; their toxic properties can negatively impact aquatic ecosystems. Fish is an essential source of protein for humans, playing a crucial role in daily food intake. Until recently, MPs were addressed primarily as environmental pollutants, but they are now increasingly recognized as contaminants in the food supply. The present review has comprehended the current knowledge of MP contamination in freshwater and marine fishes of Asia, including 112 peer‐reviewed sources from 2016 to 2023. The review recorded 422 Asian fishes (345 marine and 77 freshwater) to be contaminated with MPs. Clarias gariepinus and Selaroides leptolepi have shown maximum MP contamination in the freshwater and marine environments of Asia, respectively. Omnivorous and carnivorous fishes exhibited higher susceptibility to ingesting MPs. Benthopelagic, demersal, and reef‐associated habitats were identified as more prone to MP accumulation. In both freshwater and marine environments, China has the highest number of contaminated species among all the countries. Pollution indices indicated high MP contamination in both freshwater and marine environments. A prevalence of fibers was recorded in all fishes. Black‐ and blue‐colored MPs of <500 µm–1 mm size were found dominantly. Polyethylene terephthalate and polyethylene were recorded as the prevalent plastic polymers in freshwater and marine fish, respectively. Overall, the review served as a comprehensive understanding of MP concentrations and variations between species, between feeding habits, and between geographic locations, which can be pivotal for addressing pressing environmental challenges, protecting human health, and fostering global sustainability efforts in the face of escalating plastic pollution.
