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.

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...

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,...

Melanic hyper-pigmentation in the genus Lepidion (Gadiformes: Moridae)

Rafael Bañón, Juan Carlos Arronte, Wolf Isbert, Germán Coscelli & Francisco Sánchez
Two cases of melanic hyper-pigmentation in Lepidion lepidion are reported from two localities in Spanish Atlantic waters. A bibliographic search revealed the occurrence of this chromatic anomaly in two other Lepidion specimens, the first of them reported in the late 19th century. Macroscopically, the colour abnormality was characterized by the presence of numerous cutaneous irregular dark patches over the head, body and fins. Microscopically, melanosis corresponds to hyperplasia of dermal melanophores. Although the cause of...

A genetic method to differentiate Petromyzon marinus ammocoetes from those of the paired species Lampetra fluviatilis and L . planeri

Maria C. Urdaci, Catherine Taverny, Anne-Marie Elie & Pierre Élie
Petromyzon marinus and Lampetra sp. are protected by international conventions (Bern, 1979; Habitats directive, 1992). To estimate the abundance, and thus the precariousness of each population, it is advisable to distinguish the larvae of each species, because they may use the same environments in rivers. However, these larvae were indistinguishable on morphological criteria (oral disk, pigmentation, myomeres,…). We used a molecular method for discriminating between P. marinus and Lampetra sp. A 560 bp DNA fragment...

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.

Jakov Dulčić, Branko Dragičević, Lovrenc Lipej & Mauro Štifanić
On 12th May 2013, a specimen of Lobotes surinamensis (Lt = 342 mm, W = 845.32 g) was caught in Raša Bay (Northern Adriatic, southern coast of Istra Peninsula). This is the northernmost occurrence of this species in the Adriatic and Mediterranean Sea.

Feeding strategy and trophic ontogeny in Scorpaena maderensis (Scorpaeniformes: Scorpaenidae) from the Azores, NE Atlantic

Leonardo F. Machado, Donzília Nunes, Madaíl Ávila, Rui P. Vieira & João P. Barreiros
Feeding habits of Scorpaena maderensis Valenciennes, 1833 from the Azores archipelago were investigated. The stomach contents of 245 specimens, collected between August 1997 and July 1999, were analysed. Decapod crustaceans and teleost fishes constitute the main food items, revealing a high level of specialization by S. maderensis. Ontogenic shifts and seasonal changes in the diet composition were observed, unveiling the adaptability and opportunistic predatory behaviour of this scorpaenid.

Philippe Keith, Renny K. Hadiaty, Frédéric Busson & Nicolas Hubert
Sicyopus rubicundus n. sp., a sicydiine goby, is described from specimens collected in streams of Java and Bali (Indonesia). It differs from other species of this amphidromous genus by a combination of characters including a first dorsal fin with five spines in both sexes, a second dorsal fin with one spine and nine segmented rays, an anal fin with one spine and nine segmented rays, and a distinctive body colour in male.

Oxyeleotris colasi (Teleostei: Eleotridae), a new blind cave fish from Lengguru in West Papua, Indonesia

Laurent Pouyaud, Kadarusman, Renny K. Hadiaty, Jacques Slembouck, Napoleon Lemauk, Ruby V. Kusumah & Philippe Keith
Oxyeleotris colasi is the first hypogean fish recorded from West Papua. The habitat consists of a freshwater pool in the cave of Jabuenggara located in the heart of Seraran anticline in the limestone karst of Lengguru. The new species is most closely related to the blind cave fish O. caeca described by Allen (1996) from eastern New Guinea. The two troglomorphic species are hypothesised to be related to O. fimbriata, an epigean freshwater gudgeon that...

Sardinella aurita (Clupeidae) in Mar Chiquita coastal lagoon: morphological and DNA barcoding identification approaches

Ezequiel Mabragaña, Sergio M. Delpiani, Gabriela E. Blasina, Mariano González-Castro, Juan J. Rosso & Juan M. Díaz de Astarloa
Two specimens of Sardinella aurita were caught in Mar Chiquita coastal lagoon, Argentina, and identified by morphological and molecular features. The taxonomic status of the genus in the West Atlantic Ocean is not clear. Our results from DNA Barcoding are in accordance with those obtained with other molecular markers, which suggest conspecificity between S. aurita and S. brasiliensis.

The presence of the seahorse Hippocampus patagonicus in the Argentine Sea based on the cytochrome b sequence of mitochondrial DNA

Diego C. Luzzatto, Rodrigo Sieira, María G. Pujol & Juan M. Díaz de Astarloa
This study aimed at sequencing the mitochondrial cytochrome b gene (cyt b) of seahorses morphologically identified as Hippocampus patagonicus Piacentino {&} Luzzatto, 2004 from the two known localities where the species occur in the Argentine Sea (San Antonio Oeste and Mar del Plata). Based on the lack of substitutions within cyt b found between the individuals of both localities, the geographical range of H. patagonicus was extended up to the Northern limit of the Argentine...

First record of Kuhlia sauvagii Regan, 1913 (Perciformes) in Mayotte and Réunion islands, Western Indian Ocean

Pierre Feutry, Magalie Castelin, Henri Grondin, Corinne Cruaud, Arnaud Couloux & Philippe Keith
Kuhlia sauvagii Regan, 1913 was recently resurrected from synonymy with K. rupestris by morphological and meristic analyses. In this study, we sequenced the mitochondrial ND4 gene of these two species and used the results for molecular identifications among batches of Kuhlia. K. sauvagii, previously reported to be endemic in Madagascar, is reported here from Mayotte (Comoros) and Réunion (Mascarenes) islands, enlarging its geographical range in the Western Indian Ocean. The genetic identification method and dispersal...

Diversity and distribution of anostomoid fishes (Teleostei: Characiformes) throughout the Guianas

Brian L. Sidlauskas & Richard P. Vari
Fifty-six species or approximately 20% of the Neotropical characiform superfamily Anostomoidea (families Anostomidae, Chilodontidae, Curimatidae and Prochilodontidae) occur in the freshwaters of French Guiana, Guyana, and Suriname although these regions span only approximately 6% of the native range of this morphologically and ecologically diverse superfamily. As a result of the high diversity of anostomoids in the Guianas, the taxonomic and/or geographic boundaries of many species are poorly understood, particularly within the family Anostomidae. This contribution...

Douglass F. Hoese & Gerald R. Allen
Amphidromous species of the Glossogobius celebius complex found in lower reaches rivers of the eastern Indian Ocean and the western Pacific Ocean are reviewed. Glossogobius celebius is not as widely distributed as previously thought and is confined to the eastern Indian Ocean to eastern Indonesia. Three species are described as new species from Australia, New Guinea and various localities in the western Pacific. The species are distinguished on the basis of coloration, anal fin-ray and...

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...
