considers the possible consequences at the population and community level of the
behavioural ¯exibility shown by individual ®sh. The chapter also emphasizes themes
that recur throughout the volume, the importance of size-dependent processes and the
associated ontogenetic niche shifts in the ecology of ®shes.
There is variation in the quality of the chapters, but the overall aim of the book is
achieved. Senior undergraduates and postgraduates will ®nd valuable, critical reviews.
The suggestions for future research will appeal to all seeking research projects for
Behavioural Ecology of Teleost Fishes does point up a weakness in the current
programme of behavioural ecology. Few of the experimental or ®eld studies have
suf®cient time spans to demonstrate that individual variations in behaviour do have
consequences for the components of ®tness, especially reproductive success. Given the
importance of understanding the factors that govern demographic processes in ®shes,
there is an urgent need to demonstrate the links between individual behaviour and
population consequences that most who study the subject believe exist. The long-term
study of brown trout (Elliott, 1994), with its analyses of the consequences of
territoriality, points the way.

We all think we know what is wrong with ®sheries and what could be done to solve the
problem. What we do not know is how to devise measures that bring about catch
limitation that are respected by the ®sher. An irritant is the uncertainty attached to any
estimate of stock size or predictions of stock dynamics. This uncertainty makes it easy
for different players in the game to argue that we do not yet know enough about a ®shery
to make proper recommendations for regulation. In 1994 a symposium was organized by
the editors of this book to provide an opportunity for people to get together to discuss
®sheries management as opposed to ®sheries science. The perspective was to be global
