PREFACE
Little is known about how or when physiological characteristics of fish confer any selective advantage in the wild. Research over the past few decades has demonstrated that most whole-animal physiological measurements have extensive variability within individuals and populations of a given species. Whether this variability is, in turn, related to fitness of individuals in the field is poorly known for most animals and environments. However, knowledge of biological factors that control recruitment of individual fish and their ancestors to the reproducing population could vastly improve management models for economically important fishes and should be an important element of any ecosystem approach to future fisheries management. Moreover, although links between environmental constraints, performance, physiological and biochemical support of performance and behaviour can be elucidated in laboratory studies, we can only start to understand their interactions, ecological significance and implications for management of fish in the wild through nascent field studies. Recent developments in technology have allowed many studies evaluating the success of animals of known physiological phenotype to be gauged under natural or near-natural conditions. This symposium focuses on studies of this nature.
