Abstract This chapter explores the fi shery and biological implications of exploiting
aggregating marine fi shes, their general importance to subsistence, commercial, and
recreational fi sheries and the possible consequences of losing them. We synthesize
and examine empirical data from a wide range of taxa to determine whether, when
and why fi sh spawning aggregations need to be targets of management. We examine
the socioeconomic importance, costs and benefi ts of exploiting reef fi sh aggregations for both extractive and non-extractive (e.g. tourism and reproductive output)
purposes. We provide recommendations and guidance for future research, education, management and conservation planning for aggregating species.

This chapter explores the fi shery and biological implications of exploiting aggregating marine fi shes, their general importance to subsistence, commercial, and recreational fi sheries and the possible consequences of losing them. We synthesize and
examine empirical data from a wide diversity of species range of taxa to determine
whether, when and why fi sh spawning aggregations need to be targets of management. Although we focus on reef fi shes, we extensively use relevant or important
examples from non-reef species, where informative, because many share the same
problems of perception and lack of management; particularly illustrative examples
