The behaviour, ecology and management of predators and their prey both in the sea and in fresh water are described with particular attention to top predators, including seals, cetaceans, birds, fish and man. The methods employed by predators to capture their prey and the strategies developed by prey to evade capture are discussed. The role of predators in governing the population dynamics of prey species, and in determining the structure of ecosystems are examined and the impact of man, both as a harvester and manager of aquatic ecosystems, is considered.
