Abstract | A large volume of data is available on the biology of Acetes. In this review, we collate and synthesise information published since the genus was established by H. Milne Edwards in 1830. The review focuses on the morphology, anatomy, taxonomy, zoogeography, phylogeny, reproduction, moulting, growth, survival, morphometrics and allometry, ecology, behaviour, chemistry and physiology, food and feeding, predation, fisheries, fisheries products and processing, and on the role of Acetes in aquaculture. Some aspects of Acetes biology are still in need of study, and fundamental gaps in knowledge still exist. The anatomy of Acetes has generally been little studied, with most relevant previous work directed towards taxonomic diagnosis, resulting in a lack of basic biological data. Intrageneric relationships have been examined, but a phylogenetic tree of the family Sergestidae remains to be constructed. There are extensive data on spatiotemporal distributions of Acetes, but no reliable estimates of age are available and no studies have been made on the age structures of Acetes populations. Much information is available on the length structures of Acetes populations, and has generally been presented as a time series of histograms; further analyses have not been attempted. Study of population dynamics in Acetes has also been severely hampered by the unsubstantiated acceptance of an assumption that multiple generations may occur. Despite good documentation of swarming, little is known about the causes of this behaviour in Acetes. Although they account for at least 13.5% of the world's crustacean fisheries production, and are the largest zooplankton-based fisheries in the world, the fisheries for Acetes are largely unknown to the western world. Fishing gear is primitive, few reliable catch and effort data are available, and product-processing techniques are generally small-scale. Acetes individuals are highly gregarious, but the lack of understanding of its swarming behaviour is an impediment to effective exploitation and management of the fisheries. |
