Dietary Silica Nanoparticle Ameliorates the Growth Performance and Muscle Composition of Stinging Catfish, Heteropneustes Fossilis
Summary
Despite its title referencing nanoparticles and aquaculture, this paper studies the effects of dietary silica nanoparticles on catfish growth performance — not microplastic pollution. It examines whether silica nanoparticle feed supplements improve fish weight gain and muscle composition, and is not relevant to microplastics or human health.
Silica nanoparticles (Si-NPs) are increasingly prevalent in various industrial applications, potentially impacting aquaculture. The study investigated the effects of dietary Si-NPs on growth performance and its repercussions on muscle compositions in Stinging catfish, Heteropneustes fossilis (H. fossilis). In this study, four isonitrogenous diets containing Si-NPs (0, 1, 2, and 3 mg/kg) were fed to juvenile H. fossilis for 60 days. Several growth indices (weight gain, WG; percent weight gain, %WG; length gain, LG; and specific growth rate, SGR), feed utility parameters (feed conversion ratio, FCR; feed conversion efficiency, FCE; and protein efficiency ratio, PER) and survival rate was assessed at the end of the feeding trial. This study showed significant effects of Si-NPs (2 mg/kg) in the growth and muscle composition of H. fossilis. However, Si-NPs did not significantly affect the feed utility of H. fossilis. The findings of this study recommended that Si-NPs can be effectively supplemented into the diets of H. fossilis for better production.

Microplastics in aquaculture environments: Sources, pollution status, toxicity and potential as substrates for nitrogen-cycling microbiota
Researchers reviewed microplastic pollution in aquaculture systems, finding concentrations as high as 362 particles per liter in water and nearly 125,000 per kilogram in sediment, with microplastics accumulating in farmed fish and shellfish and potentially reaching humans through the food chain.
Protective efficacy of dietary natural antioxidants on microplastic particles-induced histopathological lesions in African catfish (Clarias gariepinus)
Researchers tested whether dietary natural antioxidants could protect African catfish from tissue damage caused by microplastic ingestion. Fish fed microplastics alone showed significant kidney, liver, and intestinal damage including cellular necrosis and tissue fibrosis, while fish receiving lycopene, citric acid, or chlorella alongside the microplastics showed substantially reduced tissue injury. The study suggests that natural antioxidant supplementation may help mitigate the harmful effects of microplastic exposure in aquaculture species.
New insights into the impact of polystyrene micro/nanoplastics on the nutritional quality of marine jacopever (Sebastes schlegelii)
Researchers investigated how polystyrene micro- and nanoplastics affect the nutritional quality of marine jacopever fish (Sebastes schlegelii), finding that nanoplastics reduced nutritional quality more severely than microplastics. Despite no notable impact on intestinal microbiota function, both particle types impaired lipid and protein metabolism pathways.
