Multi-species fish foraging associations occur whenever individuals of one or more species forage in association with one another. Although common, the theoretical background regarding foraging benefits and predator avoidance for multi-species fish foraging associations is sparse and poorly developed. However there is a vast literature on multispecies foraging associations in birds, and on the formation of single-species fish shoals, which proposes that these associations increase food availability and reduce the risk of predation, compared with foraging alone. In this review paper we assess the role these factors play in determining multi-species foraging associations in fishes. A case study of foraging in the tropical benthic carniverous goatfish, Parupeneus barberinus, is used to illustrate the importance and complexity of multi-species foraging associations to reef trophodynamics. From a review of the entire available literature of multi-species fish foraging associations, that comprises less than 45 papers, these associations could be categorised into two main types, attendant associations and shoaling associations. Attendant associations are small, comprising one or two nuclear individuals of one species that lead foraging activities, and several associate or attendant fishes. By contrast, shoaling associations are large, and the distinction between the fishes that lead foraging activities and those that attend is less clear. Attendant associations can be further divided into 4 subtypes: following and scavenging; interspecific joint hunting; hunting by riding; and aggressive mimicry. This classification is a first attempt to provide a comprehensive framework to enable the systematic evaluation of the ecological significance of these associations, and evolutionary forces that drive them.
