  • new records of species of philometra nematoda philometridae from marine fishes off new caledonia including p cephalopholidis sp n from Cephalopholis sonnerati serranidae
    Parasitology Research, 2015
    Co-Authors: František Moravec, Jean-lou Justine
    Abstract:

    Two different species of Philometra Costa, 1845 were collected from marine perciform fishes, the tomato hind Cephalopholis sonnerati (Valenciennes) (Serranidae) and the painted sweetlips Diagramma pictum (Thunberg) (Haemulidae), from off New Caledonia, South Pacific. Nematodes (only males) from the gonad of C. sonnerati represent a new taxon, P. cephalopholidis sp. n., which is mainly characterized by almost equally long spicules (length 186–228 μm), the shape and structure of the gubernaculum with a dorsally lamellate distal tip, and the structure of the caudal end. The nematodes (only gravid females) from abdominal tissues of D. pictum may represent an undescribed species, but, because of the absence of conspecific males, they could not be specifically identified. Philometra cephalopholidis is the sixth nominal species of this genus recorded from fishes off New Caledonia and the thirteenth species of these parasites described from fishes of the family Serranidae.

  • bucephalidae digenea from epinephelines serranidae perciformes from the waters off new caledonia including neidhartia lochepintade n sp
    Parasite, 2013
    Co-Authors: Rodney A Bray, Jean-lou Justine
    Abstract:

    Many bucephalid species, mainly of the subfamily Prosorhynchinae, have been described from epinepheline serranids (groupers) throughout the World’s Oceans. In this paper eight named prosorhynchine species are described and/or illustrated from epinepheline fishes from New Caledonia. Neidhartia lochepintade n. sp. in Epinephelus chlorostigma differs from other Neidhartia spp. in various combinations of distinct body-size, rhynchus size, previtelline and pre-mouth distance, post-testicular distance, cirrus-sac reach and egg-size. Other species are: Neidhartia haywardi Bott, Miller & Cribb, 2013 in Plectropomus leopardus ; Neidhartia tyleri Bott, Miller & Cribb, 2013 in Plectropomus leopardus and Plectropomus laevis ; Prosorhynchus freitasi Nagaty, 1937 in Plectropomus leopardus and Plectropomus laevis ; Prosorhynchus robertsthomsoni Bott & Cribb, 2009 in Cephalopholis argus ; Prosorhynchus longisaccatus Durio & Manter, 1968 in Cephalopholis urodeta , Epinephelus areolatus , Epinephelus cyanopodus and Epinephelus maculatus . Prosorhynchus luzonicus Velasquez, 1959 and Prosorhynchus sp. B. in Epinephelus coioides ; Prosorhynchus serrani Durio & Manter, 1968 in Variola albimarginata and Variola louti ; Prosorhynchus sp. A in Epinephelus morrhua ; Prosorhynchus sp. immature in Epinephelus coeruleopunctatus . The new combination Neidhartia longivesicula (Bilqees, Khalil, Khan, Perveen & Muti-ur-Rehman, 2009) (Syn. Prosorhynchus longivesicula ) is formed. Evidence from this paper and earlier molecular studies indicates that there are numerous morphologically similar prosorhynchine species in serranids, most of which show a high degree of host-specificity.

  • Two new species of Bothriocephalus Rudolphi, 1808 (Cestoda: Bothriocephalidea) from marine fish off Australia and New Caledonia
    Systematic parasitology, 2009
    Co-Authors: Roman Kuchta, Tomáš Scholz, Jean-lou Justine
    Abstract:

    Two new species of bothriocephalidean tapeworms, Bothriocephalus australis n. sp. from the flatheads Platycephalus bassensis Cuvier (type host) and P. aurimaculatus Knapp off southern Australia and B. celineae n. sp. from a hybrid serranid Cephalopholis aurantia (Val.) × C. spiloparaea (Val.) from off New Caledonia, are described. B. australis is unique in the possession of the combination of the three characters: an elongate, obliquely situated cirrus-sac; a wide genital atrium surrounded by chromophilic cells; and a well-developed apical disc. B. celineae is typified by the presence of a low number of testes per segment (14–26), forming one or two incomplete longitudinal bands on each side of segment, and the small size of the strobila (total length 24 mm) which consists of less than 100 segments.

  • diplectanum parvus sp nov monogenea diplectanidae from Cephalopholis urodeta perciformes serranidae of new caledonia
    Acta Parasitologica, 2008
    Co-Authors: Jean-lou Justine
    Abstract:

    Diplectanum parvus sp. nov. is described from the coral reef fish Cephalopholis urodeta collected off New Caledonia, South Pacific, and is the first diplectanid described from this fish. The new species has a very small male copulatory organ (24 μm in length) and a minute body (246 μm in length) and is close to D. nanus Justine, 2007 from which it can be distinguished by the shape of dorsal bars and various measurements. These species belong to a group of diplectanids found in groupers (Serranidae, Epinephelinae), characterised by small funnel-shaped male copulatory organs and no sclerotized female organs. The attribution of these parasites to Diplectanum Diesing is provisional. Other parasites are briefly listed.

  • Diplectanum parvus sp. nov. (Monogenea, Diplectanidae) from Cephalopholis urodeta (Perciformes, Serranidae) of New Caledonia
    Acta Parasitologica, 2008
    Co-Authors: Jean-lou Justine
    Abstract:

    Diplectanum parvus sp. nov. est décrit du poisson de récif corallien Cephalopholis urodeta pLché en Nouvelle-Calédonie, et est le premier Diplectanidae décrit de ce poisson. La nouvelle espèce a une organe copulateur mâle (long de 24 μm) et un corps (long de 246 μm) très petits et est proche de D. nanus Justine, 2007 dont elle peut eêtre différenciée par la forme des barres dorsales et diverses mesures. Ces espèces appartiennent B un groupe de Diplectanidae parasites de mérous (Serranidae, Epinephelinae), caractérisés par des organes copulateurs mâles petits en forme d’entonnoir et l’absence d’organes sclérifiés femelles, qui sont attribués provisoirement B Diplectanum Diesing. Les autres parasites sont brièvement mentionnés.

  • Spatial distribution and diet of Cephalopholis fulva (Ephinephelidae) at Trindade Island, Brazil
    Neotropical Ichthyology, 2012
    Co-Authors: Flavio Do Nascimento Coelho, Hudson T. Pinheiro, Robson Guimarães Dos Santos, Cristiano Queiroz De Albuquerque, Agnaldo Silva Martins
    Abstract:

    In this study we analyze the population structure and diet of the coney Cephalopholis fulva at Trindade Island, Brazil, through direct observation with SCUBA diving in 11 reef sites around the Island, up to 50 m deep. Diet was based on 77 individuals collected with speargun. Mean population density and biomass were estimated at 29 individuals/100 m2 and 13 kg/100 m2, respectively. This species is regularly distributed along the costal environments of the Trindade Island, with no significant differences in densities and biomass detected among the different collection habitats (reef crest, reef slope, and reef plateau). However, significantly higher densities were observed micro-habitats with greater structural complexity, which may offer more shelter and food to C. fulva. Four food item groups were identified from the gut contents of C. fulva: Annelida, Crustacea, Teleostei, and Testudinata. It is the first record of predation of the green turtle Chelonia mydas hatchlings by the coney. Trindade Island seems to present the densest concentration of C. fulva in all Brazilian and Caribbean ecosystems inhabited by this species. Scarcity of competitors, predators, and fishing pressure may explain the high densities observed in the Island.

  • Age and growth of coney (Cephalopholis fulva ), from the central coast of Brazil
    Journal of the Marine Biological Association of the United Kingdom, 2006
    Co-Authors: Júlio Neves De Araújo, Agnaldo Silva Martins
    Abstract:

    Coney (Cephalopholis fulva) otoliths were collected from 1997 to 1999 off the central coast of Brazil. Analysis of the edges of otoliths sections suggests that one translucent and one opaque zone are formed once a year. Coney age and size-ranges were 2-25 years and 172-428 mm total length (TL) respectively. The von Bertalanffy growth equation was TL t =316(1-e -0.138(t+5.301) ). The maximum age observed in this study is well above that previously reported for coney.

  • Species-specific profiles and risk assessment of perfluoroalkyl substances in coral reef fishes from the South China Sea.
    Chemosphere, 2017
    Co-Authors: Chang-gui Pan, Yinghui Wang, Ruijie Zhang, Xueyong Huang, Chaoshuai Wei, Wei-quan Wang, Weibin Zeng, Zhenjun Qin
    Abstract:

    Abstract The contamination profiles of sixteen perfluoroalkyl substances (PFAS) were examined in coral reef fish samples collected from the South China Sea (SCS) where no information about this topic was available in the literature. The results revealed that six PFAS were found in coral reef fish samples from the SCS. Perfluorooctane sulfonate (PFOS) was the most predominant PFAS contaminant detected in most of the samples, with the highest concentration value of 27.05 ng/g wet weight (ww) observed in Cephalopholis urodelus. Perfluoroundecanoic acid (PFUnDA) and Perfluorotridecanoic acid (PFTrDA) were the second and third dominant PFAS, respectively. Mean PFOS concentrations in muscle of seven coral reef fish varied from 0.29 ng/g ww in Lethrinus olivaceus to 10.78 ng/g ww in Cephalopholis urodelus. No significant linear relationship was observed between PFOS levels and coral reef fish traits (length, weight) collected in this region. Average daily intake of PFOS for the seven coral reef fishes ranged from 0.79 ng/kg/d for Lethrinus olivaceus to 29.53 ng/kg/d for Cephalopholis urodelus. The hazard ratio (HR) values for human consumption of PFOS-contaminated coral reef fishes ranged from 0.04 to 1.48, with Cephalopholis urodelus having the highest HR value of 1.18 (higher than 1) among the species, indicating frequent consumption of Cephalopholis urodelus might pose potential health risk to local population. The present work have provided the first hand data of PFAS in coral reef fishes in the SCS and indirectly demonstrated the existence of low level PFAS pollution in the SCS in China.
