Water physicochemical factors and oxidative stress physiology in fish, a review
This review examines how water quality factors like temperature, oxygen levels, pH, and pollutants (including microplastics) affect oxidative stress in fish. Oxidative stress disrupts normal cell function and can reduce fish growth, reproduction, and disease resistance. Since fish are a major protein source for many people, understanding these environmental stressors is important for both fish health and food safety.
The effects of environmental changes on the endocrine regulation of feeding in fishes
This review examines how environmental changes, including pollution and temperature shifts, disrupt the hormonal systems that control feeding and digestion in fish. Pollutants like microplastics and heavy metals can interfere with appetite-regulating hormones, leading to changes in feeding behavior and energy balance. These effects on fish health are relevant to humans because disrupted fish growth and development can reduce the nutritional quality and safety of fish as a food source.
Effects of microplastics, pesticides and nano-materials on fish health, oxidative stress and antioxidant defense mechanism
This review examines how microplastics, pesticides, and nanoparticles harm fish by causing oxidative stress, DNA damage, immune system disruption, and changes in gut bacteria. Since contaminated fish is a major pathway for microplastics and pesticides to enter the human diet, declining fish health and quality directly affect food safety and human nutrition worldwide.
A fishy tale: the impact of multiple stressors on host behaviour, physiology, and susceptibility to infectious disease
This PhD thesis studied how multiple stressors — including microplastics, chemicals, and disease — combine to affect fish behavior, physiology, and vulnerability to infections in freshwater habitats. Freshwater fish face converging threats that are driving population declines faster than any other vertebrate group.
Plastics in our water: Fish microbiomes at risk?
This review examined how microplastics and leached plasticizers affect the gut microbiomes of freshwater and marine fish, summarizing evidence for dysbiosis and reduced microbial diversity and discussing potential consequences for fish immunity, metabolism, and environmental fitness.
Global meta‐analysis reveals diverse effects of microplastics on freshwater and marine fishes
This systematic review and meta-analysis examines the effects of microplastics on fish in both freshwater and ocean environments. The findings show that microplastics reduce feeding, impair digestion, slow growth, and weaken immune function in fish, which is concerning because contaminated fish are a major food source for people worldwide.
Effects of microplastics in freshwater fishes health and the implications for human health
This review examines how microplastics affect the health of freshwater fish, which are a major protein source for billions of people. Fish ingest microplastics that accumulate in their guts, gills, and tissues, leading to inflammation, oxidative stress, and disrupted growth. Since microplastics in fish tissue can transfer to humans through the food chain, this is relevant to both ecosystem and human health.
Impacts of microplastic accumulation in aquatic environment: Physiological, eco-toxicological, immunological, and neurotoxic effects
This review summarizes how microplastics build up in fish and other aquatic life, causing damage to their immune systems, nervous systems, and overall health. When fish eat microplastics, the particles move up the food chain and can eventually reach humans through seafood consumption. The authors also discuss strategies for removing microplastics from water and reducing plastic pollution.
Effects Of Microplastics On Fish Physiology
This review examines how microplastic exposure affects fish physiology, covering accumulation patterns in different tissues, effects on organ function including liver and gill damage, antioxidant responses, and potential reproductive health consequences from both solo and combined contaminant exposures.
Assessing the Effects of Microplastics on Freshwater Fish
This review examines the growing body of research on how microplastics affect freshwater fish, documenting evidence of ingestion, tissue damage, immune system impairment, and gastrointestinal obstruction across multiple species. Researchers highlight that microplastics from personal care products and degraded plastic goods are accumulating in freshwater ecosystems at concerning rates. The study warns that combined with existing threats like overfishing and habitat loss, microplastic pollution could accelerate population declines in vulnerable fish species.
