The objective of this work was to determine aspects of reproductive biology of Blue tang surgeonfish, Acanthurus coeruleus. 496 specimens were sampled, between January 2013 and December 2015, out of which, 235 were male and 261 were female. Sexual ratio did not significanlty differ among genders, and a ratio of 1.11 females per 1 male was found. Total length frequency distribution ranged from 14 to 41.7 cm with predominance of females in the 24-32 cm classes and of males in the 26- 32 cm classes. The estimated allometric coefficient (2.7695), suggests that the species presents negative allometric growth. According to the GSI and the gonads histological analysis, the reproductive period of the species occurs from June to January with periods of greater reproductive activity from August. The oocyte diameter-frequency distribution analysis revealed a multimodal distribution, confirming the evidence of multiple spawning and batch fecundity varied from 20000 to 55000 oocytes. Spawning frequency estimates, based on the hydrated oocytes (HO) method indicated that the species spawns once every 3.8 days, while the estimates based on the post-ovulatory follicle (POF) method indicated a spawning every 3.4 days, during a 6-month spawning season lasting from August to January.

    NOTE A hybrid surgeonfish, Acanthurus triostegus x A. polyzona, from Mauritius JOSEPH H. ROWLETT Division of Insects, Field Museum of Natural History, 1400 South Lake Shore Drive, Chicago, IL 60605, USA & Department of Organismal Biology and Anatomy, University of Chicago, 1027 East 57th Street, Chicago, IL 60637, USA E-mail: [email protected] Abstract An unusually patterned surgeonfish representing a likely hybrid of Acanthurus triostegus and A. polyzona was collected and photographed from Mauritius. The specimen possesses an intermediate number of black bars (8) relative to its parent species (6 & 9, respectively), as well as having facial markings showing characteristics of both taxa. This represents the first report of a hybrid for either species. Key words: coral reef fishes, Indo-Pacific Ocean, ecology, biogeography, endemism Citation: Rowlett, J.H.

Journal of the Ocean Science Foundation, 30, 39–42. doi: http://dx.doi.org/10.5281/zenodo.1256848 The surgeonfishes of Acanthurus are a diverse, circumtropical group associated with coral reef ecosystems, where they play a dominant ecological role as herbivores (Marshell & Mumby 2015), detritivores (Tebbet, Goatley & Bellwood 2017), and, less commonly, zooplanktivores (Friedman et al. 2016). Hybridization is a well- documented phenomenon in this genus and is particularly common in so-called biogeographic “suture zones” (DiBattista et al. 2016, Payet et al. 2016), where allopatric sister species narrowly overlap. Documented examples include A. leucosternon x A. nigricans and A. tennenti x A. olivaceus in the eastern Indian Ocean (Hobbs & Allen 2014) and A. lineatus x A. sohal at Socotra, western Indian Ocean (DiBattista et al.

  • Acanthuridae
    click for previous page ACANT 1983 FAO SPECIES IDENTIFICATION SHEETS FISHING AREA 51 (W. Indian Ocean) ACANTHURIDAE Surgeonfishes, tangs, unicornfishes High-bodied, compressed fishes with a single folding lancet-like spine (Acanthurinae) or one or two bony plates usually bearing sharp keels (Nasinae on side of caudal peduncle. Mouth small, the premaxilla not protractile; teeth in a single row, variable in shape with genus, but never caniniform or molariform. A continuous, unnotched dorsal fin with 4 to 9 spines preceding the soft rays; anal fin with 2 or 3 spines preceding the soft rays; pelvic fins with 1 spine and 3 soft rays (Naso and Paracanthurus) or 1 spine and 5 rays (Acanthurus, Ctenochaetus and Zebrasoma); caudal fin truncate to lunate. Scales small. Colour: often brown or grey, but some species very colourful. Surgeonfishes and unicornfishes are most often found on or near coral reefs or rocky areas. All of the genus Zebrasoma, all but two of the species of Acanthurus and many of the Naso are herviborous; they graze diurnally on benthic algae, sometimes on seagrasses. The species of the genus Ctenochaetus feed primarily on detritus. The Ctenochaetus and one group of Acanthurus have a thick-walled, gizzard-like stomach. These fishes ingest more sediment with their food than species with thin-walled stomachs. Probably this serves to assist in the trituration of algal particles. Two of the Acanthurus, the single species of Paracanthurus and several of the Naso are zooplankton-feeders. The surgeonfishes and unicornfishes are not of great commercial value, though in insular and coastal regions with coral reefs they may be locally important.

SANTOS Genetic Fingerprinting Laboratory, Research and Ecological Assessment Division, National Fisheries Research & Development Institute, Quezon City, Metro Manila, Philippines E-mail: mudjiesantos@gmail Abstract Acanthurus albimento is described as a new surgeonfish from northeastern Luzon from six specimens collected during extensive fish-market surveys in the Philippines. The new species is characterized by a distinctive white band below the lower jaw; many irregular, wavy, thin, blue lines on the head; a brown-orange pectoral fin with a bluish tinge on the outer membrane of the rays and a dark band on the posterior margin; a narrow rust-orange stripe along the base of the dorsal fin; and a large blackish caudal spine and sheath with the socket broadly edged in black. An analysis using the mitochondrial cytochrome c oxidase subunit 1 (COI), supported by an independent multi-locus analysis, suggests phylogenetic affinities with an Acanthurus clade that includes A. auranticavus, A. bariene, A. blochii, A. dussumieri, A. gahhm, A. leucocheilus, A. maculiceps, A. mata, A. nigricauda, and A. xanthopterus; a clade that shares a suite of color characteristics. Based on the sampling history in the region, the new species may be a limited-range endemic in the westernmost Pacific Ocean, which is unusual for members of this genus.

  • Acanthurus Triostegus Bruno Frédérich1*, Orphal Colleye1, Gilles Lepoint2 and David Lecchini3
    Frédérich et al. Frontiers in Zoology 2012, 9:8 http://www.frontiersinzoology.com/9/1/8 RESEARCH Open Access Mismatch between shape changes and ecological shifts during the post-settlement growth of the surgeonfish, Acanthurus triostegus Bruno Frédérich1*, Orphal Colleye1, Gilles Lepoint2 and David Lecchini3 Abstract Background: Many coral reef fishes undergo habitat and diet shifts during ontogeny. However, studies focusing on the physiological and morphological adaptations that may prepare them for these transitions are relatively scarce. Here, we explored the body shape variation related to ontogenetic shifts in the ecology of the surgeonfish Acanthurus triostegus (Acanthuridae) from new settler to adult stages at Moorea Island (French Polynesia). Specifically, we tested the relationship between diet and habitat shifts and changes in overall body shape during the ontogeny of A. triostegus using a combination of geometric morphometric methods, stomach contents and stable isotope analysis. Results: After reef settlement, stable isotope composition of carbon and nitrogen revealed a change from a zooplanktivorous to a benthic algae diet. The large amount of algae (> 75% of stomach contents) found in the digestive tract of small juveniles (25–30 mm SL) suggested the diet shift is rapid. The post-settlement growth of A. triostegus is highly allometric. The allometric shape changes mainly concern cephalic and pectoral regions. The head becomes shorter and more ventrally oriented during growth. Morphological changes are directly related to the diet shift given that a small mouth ventrally oriented is particularly suited for grazing activities at the adult stage. The pectoral fin is more anteriorely and vertically positioned and its basis is larger in adults than in juveniles.
