Teleost (bony) fishes represent the most abundant taxonomic group of vertebrates. They are found in all conceivable types of aquatic environment and are extremely diverse behaviourally. Behavioural ecology of teleost fishes reviews the recent advances in knowledge of behavioural strategies and tactics of habitat selection and space use, foraging, predator avoidance and evasion, and reproduction among the teleost fishes. It proposes new directions and approaches for future research. It also considers the impact of individual behaviour on population and community ecology.
