“…The current results showed a high mortality rate in the NPs-exposed group compared to the control group, which demonstrated no deaths. A previous study on juvenile seabreams demonstrated that exposure to MPs (10-20 µm diameter) at a concentration of 5 µg of MP per gram of fish for 35 days increased the mortality rate among exposed fish [49]. The rise in the mortality rate in NPs exposed group may be attributed to intestinal blockage of the gut or tissue abrasions, which may cause lining epithelium injury, morbidity and mortality [50,51].…”

Contamination of the environment with nano- and microplastic particles exerts a threatening impact on the aquatic ecosystems and sustainable catfish aquaculture. The presence of nanoplastics has been found to have a detrimental impact on both aquatic and terrestrial ecosystems. The present study examines the effect of polystyrene nanoplastics (PS NPs) on the DNA, erythrocytes, oxidative status and renal histology of catfish, in addition to the potential protective effects of Chlorella vulgaris bioremediation and selenium to hinder this effect. Six equal groups of fish were used as follows: Group 1 served as a control group and received water free from PS NPs; Group 2 was exposed to PS NPs at a concentration of 5 mg/L; Group 3 was exposed to PS NPs (5 mg/L) + selenium (1 mg/kg diet); Group 4 was exposed to PS NPs (5 mg/L) + C. vulgaris (25 g/kg diet); Group 5 was supplemented with C. vulgaris (25 g/kg diet); and Group 6 was supplemented with selenium (1 mg/kg diet). The exposure period was 30 days. The results indicated that PS NPs induced oxidative stress by significantly elevating malondialdehyde activities and slightly reducing antioxidant biomarkers, resulting in DNA damage, increased frequency of micronuclei, erythrocyte alterations, and numerous histopathological alterations in kidney tissue. Selenium and C. vulgaris significantly ameliorated the oxidative/antioxidant status, reducing DNA damage, micronucleus frequency, erythrocyte alterations, and improving the morphology of kidney tissue. Nevertheless, further research is needed for a profound understanding of the mechanism behind the toxicity of nano-microplatics in aquatic systems.

“…Oryzias melastigma, the second most studied fish in this context, experiences physical impairment due to MPs ingestion, leading to growth inhibition, gut dysbiosis, weight reduction, compromised liver antioxidative condition, reproductive organ damage, and growth retardation. Another significant fish species, Sparus aurata, commonly consumed by humans, also encounters challenges due to MPs ingestion, resulting in stress, oxidative damage, behavioral alterations, compromised immune system functions, and survival difficulties [19], [20,14]. The toxicological consequences of MPs' presence can extend to fish populations, which holds noteworthy implications for humans who heavily rely on fish consumption as a staple of their diet.…”

Two marine fish species: Indian mackerel (Rastrelliger kanagurta) and finletted mackerel (Megalaspis cordyla), were collected from a local fish market near Thiruvalla in Pathanamthitta district, Kerala. Various types of microplastics (such as films, fibres, fragments, and lines) were identified using visual analysis conducted with the aid of light microscopy. This study unveiled a concentration (23%) of microplastics in gill tissues (Rastrelliger kanagurta) when compared to the skin (30%) In fish Rastrelliger kanagurta), indicating different pathways of uptake. Megalaspis cordyla had a greater percentage of microplastics in the skin (25%) than in the gills (22%); also indicating different pathways. There was an abundance of microplastics in the form of film at (25%) than in flake, granules, foam, fibre etc. which all stood at 10%, 10%, 10% and 20% abundance, respectively. Notably, Indian mackerels were found to harbour a more significant microplastic load than finletted mackerels, highlighting the existence of inter-species variations in contamination levels. To confirm the presence of polymers, the identified microplastics underwent Fourier-transform infrared (FTIR) spectroscopy analysis, a method that verified the molecular composition of micro plastics by analysing their infrared absorption spectra. Overall, these findings shed light on the prevalence of microplastic pollution in aquatic ecosystems and underscore the necessity for comprehensive strategies to mitigate its far-reaching repercussions.

“…Multiple mechanical impacts have been directly or indirectly linked to plastics including entanglement in macro-plastics (impeding mobility, leading to starvation or drowning), and the ingestion or inhalation of smaller plastic debris, such as micro-plastics (MPs) and nano-plastics (NPs; Welden, 2020). In fish, most ingested MPs and NPs are eventually excreted, but a small fraction can accumulate in organs and tissues (mainly in the intestine and liver) causing severe tissue damage and inflammation (e.g., Jovanović 2017;Wang et al, 2019;Araújo et al, 2019;Jacob et al, 2021;Marana et al, 2022).…”
