Eleotris (Teleostei: Eleotridae) of the Indian Ocean: an overview with the description of three new species

Marion I. Mennesson & Philippe Keith
Recent research studied the complexity of the taxonomy of the genus Eleotris (Teleostei: Eleotridae) highlighting the presence of cryptic species in the Indo-Pacific area. Eleotris species are one of the most common fish in lower and medium parts of insular freshwater streams. Here we studied specimens from several localities in the Indian Ocean and we described three new species (Eleotris diamsoi, E. sahanaensis, and E. valadei), and we redescribed E. pellegrini Maugé 1984, E. vomerodentata Maugé, 1984 and E. soaresi...

Deduced primary structures of three vitellogenins and specific binding to putative multiple ovarian receptors in white perch (Morone americana)

Benjamin J. Reading, Naoshi Hiramatsu, Takahiro Matsubara, Akihiko Hara & Craig V. Sullivan
Three complete cDNA s encoding different forms of vitellogenin (vtg) were cloned from a white perch (Morone americana) liver cDNA library. The two longest cDNA s encoded Vtgs with a complete suite of yolk protein domains that, based on comparisons with vtg sequences from other species, were categorized as VtgAa and VtgAb. The shorter cDNA encoded a Vtg that lacked a phosvitin domain, had a shortened C-terminus, and was categorized as VtgC. Ligand blots and...

Motility activation and subpopulation analysis in Solea senegalensis spermatozoa

Elsa Cabrita, Felipe Martinez-Pastor, Florbela Soares & Maria Teresa Dinis
Computer Assisted Sperm Analysis (CASA) has been successfully applied in the study of fish sperm motility. Once these spermatozoa are characterized it is possible to group in homogeneous subpopulations with similar motility patterns. This analysis could have further implications for the selection of appropriate husbandry conditions during reproductive season. Solea senegalensis sperm was colleted weekly from 44 fish during May-July. The effect of pre-dilution solutions and the composition of the motility activating solutions were analyzed....

Length-weight, length-length and a proposed empirical standard weight equations for the Italian endemic cyprinid species Sarmarutilus rubilio

Daniela Giannetto, Giuseppe Maio, Laura Pompei, Stefano Porcellotti & Massimo Lorenzoni
Length and weight data of 21,040 specimens of the Italian endemic species Sarmarutilus rubilio (Bianco & Ketmayer, 2014) were collected throughout the area of distribution of the species and used to cal- culate total length-weight (TL-W), standard length-total length (SL-TL), fork length-total length (FL-TL), and standard weight (Ws) equations. The SL-TL equation was TL = 1.153 SL + 4.121; the FL-TL equation was TL = 1.037 FL + 0.288. The log-transformed TL-W equation was: log10W...

Allozymic variability in European anchovy Engraulis encrasicolus ( L .) along the Moroccan coasts

Khalil Chahdi Ouazzani, Touria Benazzou & Malika Chlaida
Allozyme variation was used to investigate for the first time the genetic structure of European anchovies, Engraulis encrasicolus (Linnaeus, 1758), along the Moroccan coasts. A total of 420 individuals were collected at 11 sites during the anchovy spawning period of 2012. Eleven loci were tested, among them only LDH* [E.C:1.1.27] and PGM * [E.C:] were polymorphic. Statistical analysis results showed no significant differentiation between samples (overall FST = 0.0077, p = 0.13). Genotypic proportions were...

Long term monitoring of coral and fish assemblages (1983-2014) in Tiahura reefs, Moorea, French Polynesia

René Galzin, David Lecchini, Thierry Lison de Loma, Charlotte Moritz, Valeriano Parravicini & Gilles Siu
Coral reefs are one of the most diverse ecosystems on Earth and sustain millions of people worldwide. However, coral reefs are temporally dynamic and fragile systems subject to ever increasing disturbances of anthoropogenic and natural origins. Understanding the patterns and trajectories of changes through time is urgently needed to estimate the resilience of coral reefs. To ascertain these patterns, we depend on the availability of long-term datasets, which are seldom available. In this study, we...

New insights into the chromosomal differentiation patterns among cichlids from Africa and Madagascar

Catherine Ozouf-Costaz, Jean-Pierre Coutanceau, Céline Bonillo, Hervé Mercot, Yves Fermon & Chantal Guidi-Rontani
To increase understanding of the chromosomal diversity among cichlid species, karyotypes of 19 species of Cichlidae belonging to 15 genera (Paratilapia polleni, Chromidotilapia guntheri guntheri, Hemichromis fasciatus, Steatocranus irvinei, Stomatepia pindu, Altolamprologus compressiceps, Julidochromis transcriptus, Neolamprologus tetracanthus, N. brevis, Gnathochromis permaxillaris, Eretmodus cyanostictus, Astatoreochromis alluaudi, Haplochromis callipterus, H. paludinosus, Nimbochromis livingstonii, N. polystigma, Pseudocrenilabrus multicolor victoriae, P. philander and Ctenochromis horei) were investigated for the first time. In spite of the variation in the karyotypes...

Jakov Dulčić, Branko Dragičević, Pero Ugarković & Pero Tutman
The 10th October 2016, a specimen of Micropterus salmoides was caught by trammel net in the Mala Neretva River (Adriatic drainage system of Croatia). This is the first occurrence of the Largemouth black bass in this river, and by the way, in the hydrographic drainage system to the Adriatic Sea.

Annotated checklist for fishes of the Main Nile Basin in the Sudan and Egypt based on recent specimen records (2006-2015)

Dirk Neumann, Henriette Obermaier & Timo Moritz
The results of several short ichthyological surveys on the Nile Basin in Sudan between 2006 and 2015 are presented. In attempting to represent major type localities and recently observed variability, we complement known field records with records of a reference collection of recent fish bones collected during the 1980s and records of aberrant cichlids populations in Egypt observed at El Fayum and in lakes of the Nile Delta. From 133 native species in the Republic...

Using body mass index (BMI) to estimate mercury contamination of the blue shark (Prionace glauca) and the shortfin mako (Isurus oxyrinchus)

Sebastian Biton Porsmoguer, Ivan Dekeyser, Daniela Banaru, Marc Bouchoucha & Françoise Marco-Miralles
Blue shark (Prionace glauca) and shortfin mako (Isurus oxyrinchus) specimens were caught in the North-eastern Atlantic Ocean by Spanish and Portuguese longliners. They are considered as top-predators, particularly susceptible to bioaccumulate mercury (Hg). The Hg mean levels in blue shark and shortfin mako were 0.4 (SD = 0.3 mg kg-1) and 0.5 (SD = 0.9 mg kg-1), respectively. The body mass index (BMI) was tested to demonstrate the accumulation of Hg in these two top-predators,...

Otolith shape differences between Micropogonias manni and M. altipinnis (Sciaenidae)

Lina-Maria Duque-Vélez, Philippe Béarez & Raphaël Cornette
Sagitta morphology is much used in sciaenid systematics, as well as in archaeological, paleontological and ecological studies. Although morphometric characteristics of sagitta (length, height, thickness, weight,…) are useful to discriminate some marine and freshwater species, they are not fully conclusive in the case of Micropogonias altipinnis and M. manni. In order to give new elements for characterizing and discriminating these species we propose here to apply the geometric morphometry technique to sagittae of these species...

The detection of weakly developed plicidentine in teleost teeth using 3D tomography

Damien Germain, Jorge Mondéjar-Fernández & François J. Meunier
The detection of weakly developed plicidentine in ground sections can be difficult, because these structures cannot always be resolved by analysing two-dimensional thin-sections. X-ray tomography followed by 3D virtual modelling allows the non-destructive study of the spatial morphology of these important structures. Here, we illustrate dentine folds in the pulp cavity of the teeth in three teleost fishes, Arapaima gigas (Osteoglossiformes), Hoplias aimara (Characiformes) and Lophius piscatorius (Lophiiformes), and add data from a lepisosteid, Lepisosteus...

Fishing at Qal’at al-Bahrain, archipelago of Bahrain, from the Early Dilmun (2200 BC) to the Middle Islamic period (13-16th centuries AD)

Justine Vorenger
Excavations have taken place at the site of Qal’at al-Bahrain in Bahrain, Arabo-Persian Gulf, since the 1950’s. They have revealed significant architectural remains and a rich assortment of material, including ceramics, metal objects, figurative representations, inscriptions, seals, and botanical and faunal remains, which include a large number of fish bones. Its exceptional stratigraphy, which extends from the Early Dilmun (ca. 2200 BC) to the Middle Islamic period (13-16th centuries AD), enables us to study and...

Amphidromous life cycle of Eleotris fusca (Gobioidei : Eleotridae), a widespread species from the Indo-Pacific studied by otolith analyses

Marion Isabelle Mennesson, Hélène Tabouret, Christophe Pécheyran, Eric Feunteun & Philippe Keith
Eleotris fusca is a widespread amphidromous fish found in the Indo-Pacific area. Its life cycle is characterised by a marine pelagic larval phase allowing the species to disperse in the ocean and then to recruit to remote island rivers. In order to examine its migratory history and pelagic larval duration (PLD), otolith microchemical and microstructural analyses were undertaken on 100 specimens collected in the rivers of four areas: Mayotte, Reunion Island (Indian Ocean), Vanuatu and...

Invalidity of Gasterosteus gymnurus (Cuvier, 1829) (Actinopterygii, Gasterosteidae) according to integrative taxonomy

Gaël P.J. Denys, Matthias Geiger, Henri Persat, Philippe Keith & Agnès Dettaï
The three-spined stickleback Gasterosteus spp. is a model organism largely used in biology. Four species have been described in Europe: G. aculeatus, G. gymnurus, G. islandicus and the extinct G. crenobiontus. Our integrative taxonomy study, including 194 specimens, demonstrates that these taxa are distinguishable neither with the mitochondrial COI marker nor the morphological characters like lateral plates, supposed to differentiate them. Thus, we invalidate Gasterosteus gymnurus, and we consider it as junior synonym of Gasterosteus...

A revised...

Three new species of Lentipes from Indonesia (Gobiidae)

Philippe Keith, Renny K. Hadiaty, Nicolas Hubert, Frédéric Busson & Clara Lord
Three new species of Lentipes (L. argenteus, L. ikeae and L. mekonggaensis), freshwater gobies, are described from streams of Sumatra, Java, Bali and Sulawesi (Indonesia). They differ from other species of the genus by a combination of characters including an urogenital papilla lacking lateral lobes and retractable into a sheath-like groove, the number of pectoral fin rays, the number of scales, tricuspid teeth in the upper jaw, and a specific body colour in males.
