Overview

Fish are aquatic, gill-bearing vertebrates that constitute the most diverse group of vertebrate animals, spanning jawless, cartilaginous, and bony lineages across marine and freshwater environments. As ectotherms adapted to life in water, they exhibit specialised physiology for gas exchange, osmoregulation, buoyancy, and sensory perception, and they occupy positions throughout aquatic food webs from primary consumers to apex predators. In marine and fisheries science, fish are studied both as components of ecosystems and as exploited resources, making their population dynamics, reproduction, growth, and responses to environmental stressors central concerns. The peer-reviewed research collected here reflects this breadth, addressing the factors affecting wild populations such as Atlantic salmon, the design of broader and more sustainable approaches to fisheries management, and the structure of pelagic food webs linking krill, fish, and higher predators. A further strand examines anthropogenic pressures on fish, including the toxicological effects of heavy metals, pesticides, and herbicides, the impact of underwater sound and organic pollutants, and the molecular and species-level assessment of freshwater fish. Applied work on aquaculture, fish culture systems, dietary protein, and the nutritional properties of fish-based products extends the topic toward food security and production. Together these studies frame fish as organisms of ecological, economic, and human-health significance within the aquatic sciences.
