Impeding Effect of Polystyrene Microplastic Pollutants on Hg2+ Uptake Potential of Aspergillus flavus
AI summary Read the abstract
Agricultural waste products like rice husks can boost fish immunity and growth when added to their diet. This matters because healthier farmed fish mean safer food for humans and less need for antibiotics in aquaculture. The study shows we can use abundant farm byproducts to improve both fish health and food security.
Pathogen and stress-related morbidities are the main challenges in tilapia farming.Improving the immune health is an effective approach to protect tilapia against these pathogens.Phenolic content and antioxidant activity of rice husk (RH), sugarcane bagasse (SB), and corn cob (CC) evaluated by Folin-Ciocalteau assay and DPPH assay revealed high total phenolic content and antioxidant activity in RH compared to CC and SB.LCMS analysis of RH, SB, and CC exhibited the presence of hydroxybenzoic acid and hydroxycinnamic acid in agricultural waste samples.Effects of RH, SB, and CC on growth performance, gut microbial flora, innate immunity, and hematology of hybrid red tilapia (Oreochromis aureus X Oreochromis mossambicus) were evaluated in 91 days feeding trial with a test diet supplemented with 10% RH, SB, CC to basal diet (BD) ingredients in optimum conditions of growth.Growth performance data was recorded at an interval of 13 days.At the end of feeding trial, fish gut microflora, skin mucus bactericidal activity, blood serum lysozyme, and bactericidal activity against Shigella sonnei, and hematological parameters were evaluated.Significant difference in growth performance of red tilapia fed with experimental diets was observed.RGR (relative growth rate) was lowest in BD (380.79 ± 46.26) and observed highest in RH (554.01 ± 83.24).Lactobacillus count was increased in all experimental groups.Decrease in Salmonella sp., Shigella sp., and E. coli count was observed in CC.All experimental groups showed enhanced serum bactericidal activity against Shigella sonnei.SB group showed the highest serum bactericidal activity.Skin mucus bactericidal activity was also highest in SB.Least skin mucus bactericidal activity was presented by BD. Results of research work indicated that RH, SB, and CC have bioactive ingredients that positively influenced the growth performance, innate immune response, and hematology of red tilapia.Agricultural by-products are abundant biomass and rich in bioactive and nutraceutical compounds, therefore these are good candidates for maintaining redox balance, health status and growth performance in fish.

New insights into the inhibitory role of microplastics and heavy metals in antibiotic resistance dissemination within marine aquaculture systems
AI summary Read the abstract
This review of lab studies suggests that microplastics and heavy metals in fish farms don't always make antibiotic resistance worse, as commonly assumed. Under certain conditions, like salty water and aged plastic particles, they may actually trap metals and reduce the spread of resistant bacteria. However, this protective effect is fragile and still needs to be confirmed in real ocean farms before we know if it truly helps limit antibiotic resistance risks to seafood and human health.
A combined hazard to mariculture: Quality and safety impairment associated with intestinal barrier disruption in fish co-exposed to environmentally relevant microplastics and antibiotics
AI summary Read the abstract
Tiny plastic particles in ocean fish farms can act like sponges, soaking up antibiotics and making it easier for fish to absorb them, damaging their gut health and reducing their nutritional quality. In this study, farmed fish exposed to both microplastics and a common antibiotic had more of the drug build up in their edible muscle, though levels were still within safe limits for human consumption based on current estimates. The findings suggest that microplastic pollution could be quietly amplifying other contamination problems in our seafood, highlighting a need for closer monitoring of farmed fish as microplastic pollution continues to rise.
A review of microplastic pollution in aquaculture: Sources, effects, removal strategies and prospects
AI summary Read the abstract
This review examines how microplastics contaminate fish farms through environmental inputs and aquaculture equipment, affecting water quality and the health of farmed seafood. Since contaminated aquaculture products are a direct pathway for microplastics to reach the human diet, reducing plastic pollution in fish farming is important for food safety.
Effect of Microplastic Amendment to Food on Diet Assimilation Efficiencies of PCBs by Fish
AI summary Read the abstract
Goldfish fed food mixed with PCB-contaminated microplastics absorbed only slightly more PCBs than fish fed just PCB-contaminated food without microplastics. This suggests that microplastics may not significantly increase the amount of PCBs that fish absorb from their diet, though they do act as carriers.
