Microplastics and pesticides are emerging contaminants in the marine biota, which cause many harmful effects on aquatic organisms, especially fish. Fish is a staple affordable food source, rich animal protein, along with various vitamins, essential amino acids, minerals. Exposure of fish to microplastics, pesticides, nanoparticles generates ROS induces oxidative stress, inflammation, immunotoxicity, genotoxicity, DNA damage alters gut microbiota, thus reducing growth quality Changes behavioral patterns, swimming, feeding habits were also observed under exposures above contaminants. These affect Nrf-2, JNK, ERK, NF-κB, MAPK signaling pathways. And Nrf2-KEAP1 signalling modulates redox status marinating enzymes Effects found modulate antioxidant enzymes, including superoxide dismutase, catalase, glutathione system. So, protect health from contribution nano-technology or nano-formulations was researched. A decrease nutritional population significantly impacts human diet, influencing traditions economics worldwide. On other hand, traces microplastics habitat water can enter humans by consuming contaminated may result serious hazards. This review summarizes stress caused due nano-particle contamination exposure their impact health. As rescue mechanism, use management disease discussed.

Aquatic ecotoxicity of glyphosate, its formulations, and co-formulants: evidence from 2010 to 2023

Environmental Sciences Europe, Journal Year: 2024, Volume and Issue: 36(1)

Published: Feb. 6, 2024

Abstract Glyphosate (GLY), the most widely used herbicide active ingredient (AI) in world, is frequently detected aquatic environments where it can affect non-target organisms. Globally, more than 2000 commercial GLY-based herbicides (GBHs) are to control weeds. Non-target organisms exposed complex pesticide formulations under real environmental conditions, but co-formulants contained GBHs classified as so-called inert and inactive ingredients terms of their biological effects. The main objective this comprehensive review compile results ecotoxicological studies on side-effects GLY, GBHs, formulating agents. Based demonstrated for a variety plant animal organisms, oxidative stress appears be major trigger these adverse effects, affecting integrity DNA other biochemical functions. Furthermore, there evidence impairment various physiological behavioral Adverse effects GLY have been observed even at very low concentrations. There also differences sensitivity tested, with similar lifestyles, habitats or identical taxa. typically investigate short-term single exposure GLY/GBH species, whilst reality multiple applications together pesticides common during cropping cycle. Moreover, interactions between GLY/GBHs contaminants rarely studied. Higher toxicity compared alone has often observed, demonstrating that highly toxic own markedly increase GBH formulation. possible impurities such heavy metals, cause additional problems environment food safety. widespread massive use leads increased hazards. In addition, need revision risk assessment system emphasized. According studies, current pollution by problematic cannot considered environmentally sustainable. It is, therefore, necessary least tighten permitted forms use.

Ameliorating effects of natural herbal supplements against water-borne induced toxicity of heavy metals on Nile tilapia, (Oreochromis niloticus)

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: Sept. 29, 2024

Abstract The efficacy of herbal supplements in mitigating heavy metals (HMs) toxicity was investigated using a widely grown fish, the Nile tilapia ( Oreochromis niloticus ). experiment conducted over two phases: during stress phase, experimental fishes were exposed to sub-lethal concentrations HMs, including lead, cadmium, zinc, and copper for 15 days; following which feeding given 70 days ameliorate their effects. Seven groups established: control negative group (CON−ve), positive (CON+ve, without any treatment), five with supplementation 1% turmeric (TUR), cinnamon (CIN), ginger (GIN), garlic (GAR), mixture (MIX), respectively. A total 315 distributed evenly tanks (15 per tank, triplicates). results revealed that exposure HMs led significant p < 0.05) alterations all tested parameters, i.e., liver damage growth reduction. supplements, especially MIX groups, ameliorated harmful effects restored fish growth, digestibility, carcass composition, health. In conclusion, study demonstrated effective reducing HMs-linked tilapia. Future studies pertaining mechanisms facilitated by various bioactive substances-linked tolerance are warranted.

Unstable outdoor farming conditions weaken fish's health status and immunity, leading to high susceptibility infectious diseases low productivity. Feed additives have been applied recently enhance the growth performance well-being of striped catfish. This study evaluated effects ginger (Zingiber officinale) on performance, digestive enzyme activity, antioxidative response, antibacterial capacity Control three test diets were supplemented with rhizomes powder at 0.5 %, 1 1.5 %. After 90 days, catfish fed dietary was marginally increased, highest being in group receiving % (p < 0.05). However, feed conversion ratio reduced following same trend, lowest fish Fish had hormone level than remaining groups The carcass composition, including total protein lipids, meaningfully affected by ginger, while ash fibers unaffected. Amylase, protease, lipase activities significantly higher control. protein, albumin, globulin 0 Superoxide dismutase, catalase, glutathione peroxidase regardless dose.

Abstract The investigation of the toxic potential a newly introduced herbicide, Florpyrauxifen-benzyl (FPX), on Nile tilapia ( Oreochromis niloticus ) was aim this study. For 96 h, median lethal concentration (LC 50 assessed in fish juveniles using Probit analysis following exposure to five concentrations FPX (2–3 ppm). investigating some mechanisms toxicity, were allocated into three groups (0, 0.27 and 0.54 ppm FPX) cut-off intervals at 7 15 days. Liver malondialdehyde (MDA) reduced glutathione (GSH) levels assessed. In addition, superoxide dismutase (SOD) catalase (CAT) evaluated both transcriptional enzymatic activity levels. Histopathological effects liver erythrocytic nuclear abnormalities (ENAs) monitored too. 96h-LC found be 2.61 ppm, revealing tilapia. Concentrations induced oxidative stress by altering activities antioxidant enzymes their transcripts. genotoxic effect evidenced significant P < 0.05) increase micronuclei (MNs) ENA frequencies. Significant histopathological alterations observed concentrations, with highest FPX. Results suggest that may exert oxidative, genotoxic, non-targeted species such as if it is used improperly. Although could an indicator for materials aquatic habitat, future studies other organisms, or durations are recommended.
