The role of environmental stress in fish health: A review
AI summary Read the abstract
This review examines how environmental stressors including temperature changes, pesticide contamination, microplastics, and algal blooms affect fish health. Researchers found that these factors substantially influence fish growth, reproduction, respiration, and metabolic function. The study emphasizes the need for new strategies to address the growing impact of environmental changes on aquatic ecosystems and the global fish economy.
Fish are regarded as a crucial indicator of alterations in the aquatic environment due to their position at the apex of the food chain. Monitoring these alterations is crucial for identifying modifications in the aquatic ecosystem. The principal elements influencing fish health are temperature, pH, dissolved oxygen, salinity, pesticide contamination, microplastics, and algal presence. These elements substantially influence fish health regarding development, reproduction, respiration, oxygen stress, and the internal enzymes associated with digesting and other metabolic functions. Alterations in global environmental conditions and anthropogenic pollutants result in modifications to fish populations, their lives, and their behavior and mobility, therefore directly or indirectly affecting the world economy and overall environmental equilibrium. This study presents a comprehensive analysis of the environmental alterations and determinants influencing fish health. It aims to elucidate impending environmental issues impacting fish, necessitating the development of methods and strategies to deal with these changes.

Effects of microplastics, pesticides and nano-materials on fish health, oxidative stress and antioxidant defense mechanism
AI summary Read the abstract
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
AI summary Read the abstract
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.
