In the domain of decision-support tools for the management of marine ﬁsh resources, considerable attention has been paid to the development of models explaining how ﬁsh stocks change over space and time. In most models, ﬁshing effort is assumed to be exogenous and determined by factors such as management. Increasingly, there has been a call for bio-economic models to also account for the dynamics of ﬁshing ﬂeets, recognizing that ﬁshers respond to changing environmental, institutional and economic conditions. A growing literature has sought to explicitly model the endogenous determinants of the capacity of ﬁshing ﬂeets, the intensity of its use and its temporal and spatial allocation across ﬁshing opportunities. We review this literature, focusing on empirical applications of the behavioural models that have been put forward to explain and predict observed ﬂeet dynamics. We ﬁnd that although economic factors are usually included as a dominant driver in most studies, this is often based on the use of proxy variables for the key economic drivers, for which adequate data are lacking. Also, while many studies acknowledge that social and social–psychological factors play a signiﬁcant role in explaining observed ﬁshing behaviour, their inclusion in ﬁshing ﬂeet dynamic models is still very limited. Progress in this domain can only be achieved via the development of multidisciplinary research programmes focusing on applied quantitative analysis of the drivers of ﬁshing ﬂeet dynamics.
