The parasitic isopod Anilocra physodes, as a novel food source for the lizardfish Synodus saurus (Synodontidae)

Pauline Narvaez, João P. Barreiros & Marta C. Soares
During a wide project carried out on the behavior and reproduction of the Atlantic lizardfish Synodus saurus in the Azores (NE Atlantic), specimens of the ectoparasitic isopod Anilocra physodes were discovered in various stomachs contents of these piscivorous predatory fish. This intriguing result allowed us to conclude for the first time that fish species can ingest their own parasites, which becomes doubly beneficial, since it releases them from parasites but it is also a new...

Comparative histology of caniniform teeth in some predatory ichthyophagous teleosts

Megann Texereau, Damien Germain & François J. Meunier
In the present study, the combined use of classical histological and 3D reconstruction methods allows us to characterize the structural organization of different types of dentine in five species of predatory teleosts. The examination evidences the presence of vasodentine and of plicidentine in the perciform Dissostichus eleginoides Smitt, 1898 and the presence of osteodentine in three other species of Perciformes without any plicidentine, Thyrsites atun (Euphrasen, 1791), Sphyraena guachancho Cuvier, 1829, Lepidopus caudatus (Euphrasen, 1788),...

Vlasta Bartulović, Jakov Dulčić, Ivan Bogut, Jerko Pavličević, Edhem Hasković & Branko Glamuzina
On 17 April 2010, one specimen (m) of freshwater bream (total length TL = 43.8 cm, weight W = 1046.8 g) was captured with a trammel net near the settlement Mihalj, Mala Neretva River (Adriatic drainage system of Croatia). This is the first record of the freshwater bream in this river and consequently for the Adriatic drainage system as a whole.

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...

Description of three new species of dwarf Glossogobius from New Guinea and northern Australia

Douglass F. Hoese, Gerald R. Allen & Renny K. Hadiaty
The current paper describes three, highly distinctive, new species of Glossogobius from southern New Guinea and northern Australia. The species differ from other species of Glossogobius in the combination of small size (maximum size to 50 mm SL), strong sexual dimorphism in mouth and fin sizes and reductions of nape scales and head pores in two of the species. The new taxa are known from small rivers and streams at elevations of less than 100...

Evidence of late migrant smolts of Atlantic salmon (Salmo salar) in the Loire-Allier System, France

Hélène Imbert, Patrick Martin, Jocelyn Rancon, Vincent Graffin & Sylvie Dufour
Smolts of Atlantic salmon Salmo salar of the Loire-Allier system have to perform an exceptional distance of 900 km to reach the ocean from the upstream spawning grounds, while being subjected to connectivity disruption induced by the presence of dams as well as fluctuating climatic conditions. In order to successfully perform their marine entry, smolts should reach the estuary within a limited suitable period. This study concerns smolt emigration dates from upper Allier, and arrival...

Histological study of the jaw teeth in the Devonian actinopterygian †Cheirolepis canadensis (Whiteaves)

François J. Meunier, Olga Otero & Michel Laurin
†Cheirolepis bears two series of teeth on its jaws: one with sharp caniniform teeth and a second one with smaller teeth. The good preservation of the fossil material from Miguasha (Canada) has allowed a histological study of the various tissues of teeth and jaws. Caniniform teeth are composed of a core of orthodentine with an apical cap of acrodine. The walls of the pulp cavity show incipient folds located at the tooth base. These folds...

Comparative osteological study of three species of distinct genera of Haplotilapiini (Cichlidae)

Katrien Dierickx, Wim Wouters & Wim Van Neer
In palaeontological and archaeozoological studies dealing with tilapia remains, identifications are usually limited to the level of the tribe Tilapiini (now called Haplotilapiini). In the present study, dry skeletons of Oreochromis niloticus (Linnaeus, 1758), Oreochromis aureus (Steindachner, 1864), Sarotherodon galilaeus (Linnaeus, 1758) and Coptodon zillii (Gervais, 1848) were analysed with the aim of defining morphological characters on a series of isolated skeletal elements. Eighteen different skeletal elements that have good chances of being well preserved...

Premier signalement de Pseudanthias bicolor (Serranidae) sur différents habitats artificiels à La Réunion

Mathieu Pinault, Julien Wickel, David Guyomard, Ronald Fricke & Jean-Pascal Quod
Malgré le nombre élevé d’études réalisées sur les peuplements ichtyologiques des zones récifales de l’île de la réunion au cours des quarante dernières années, l’anthias bicolore Pseudanthias bicolor (ran -dall, 1979), précédemment recensé à Maurice et aux Maldives dans l’océan indien, n’a jamais été observé sur les récifs coralliens de l’île. Deux spécimens de cette espèce ont été photographiés récemment sur des habitats artificiels lors de suivis scientifiques en plongée sous-marine. La présente étude, fondée...

Comparative morphology and mechanical properties of the lepidotrichia of climbing and non-climbing Hawaiian gobioid fishes

Natalia K. Taft, Benjamin N. Taft, Hailey Henck, Kelly M. Diamond, Heiko L. Schoenfuss & Richard W. Blob
Many gobioid fishes from tropical islands exhibit amphidromous life histories, in which juveniles migrate from the ocean to upstream freshwater habitats. However, upstream reaches are blocked by waterfalls on many islands. In some species, juveniles climb these waterfalls with the aid of an adhesive sucker formed from fusion of the pelvic fins. Adults of some species may also climb waterfalls to return upstream if they are dislodged by pulses of high flow. Several structural features...

Hatching success in brackish water of Perca fluviatilis eggs obtained from the western Baltic Sea

Emil A. F. Christensen, Mikkel Skovrind, Morten T. Olsen, Henrik Carl, Peter Gravlund & Peter R. Møller
Estuaries are important spawning areas for many freshwater and marine fishes. This is also the case for Baltic populations of European perch Perca fluviatilis, an important commercial species in most of Europe. There is, however, inconsistency in the literature between the maximum salinity tolerance of the eggs in vivo, and the salinities at which some populations spawn in situ (7 vs. 9.6‰). In the present study, hatching success of perch was determined in vivo for...

Does depth become a permissive factor for reproductive habitat selection in the reef-associate damselfish Chrysiptera cyanea?

Tatsuki Fukuoka, Satoshi Imamura, Yuki Takeuchi, Muhammad Badruzzaman, Sung‑Pyo Hur, Selma Bouchekioua & Akihiro Takemura
The sapphire devil Chrysiptera cyanea (Quoy & Gaimard, 1825) is a reef-associated damselfish. Because this species exhibits repeated active reproduction in shallow seas during the spawning season, it is hypothesized that there is a preferred depth for successful reproduction. The aim of this study was to clarify whether the reproductive activity of the sapphire devil is influenced by habitat depth. In a field survey, many individuals could be seen in shallow areas (0-1.5 m), but...

A new species of Belobranchus (Teleostei: Gobioidei: Eleotridae) from Indonesia

Philippe Keith, Renny K. Hadiaty & Clara Lord
A new species of Belobranchus, a freshwater Eleotridae, is described from streams of Indonesia. It differs from the other only species belonging to the genus by a combination of characters including the scales in transverse forward series (22-28 versus 27-35), in transverse back series (18-21 versus 20-23), in predorsal scales (16-23 versus 21-34), and the in vivo general colour pattern. Particularly the caudal fin is never spotted but generally translucent with some yellow or reddish...

Monophyly of the genus Liopsetta (Pleuronectidae)

Elena Voronina & Bruno Chanet
A phylogenetic analysis of 15 flatfish species based on 40 morphological characters was conducted to determine the interrelationships of the genera Liopsetta, Pleuronectes and Pseudopleuronectes. The results indicate that Liopsetta forms a monophyletic lineage defined by the reduction of the infraorbital sensory canal of the ocular side, small scale size and small body size. The monophyly of Pseudopleuronectes (including P. obscurus) is supported by the interrupted coronal commissure and of Pleuronectes by the presence of...

New biological data on Fistularia commersonii in the central Mediterranean Sea

Luca Castriota, Manuela Falautano, Pietro Battaglia, Alberto Oddo & Franco Andaloro
Preliminary data on age, growth and diet of bluespotted cornetfish Fistularia commersonii Rüppell, 1838 (Fistulariidae) in the central Mediterranean Sea are provided. In the study area, this invasive Lessepsian fish showed piscivorous behaviour, focusing mainly on labrids, clupeids and sparids. Prey composition suggests that bluespotted cornetfish explores various habitats for hunting. Prey fishes were mainly juveniles and their size showed positive correlation with predator size. Estimated by vertebrae readings, ages of bluespotted cornetfish, having sizes...

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.

S7 characterization of Western European pikes Esox spp. (Actinopterygii, Esociformes

Gaël P.J. Denys, Théo Lauga, Giovanni B. Delmastro & Agnès Dettaï
The comparison of a 1635 bp fragment of the first intron of the S7 ribosomal protein coding gene, a commonly used phylogenetic marker, for specimens from the three European pike species Esox aquitanicus, Esox cisalpinus and Esox lucius highlights diagnostic sites and indels constituting molecular synapomorphies. Both the sequence alignment and the phylogenetic tree discriminate these three species, even with a short sequence fragment. Three Esox lucius haplogroups can be separated. These haplogroups might correspond...

Major fishery events in Kerguelen Islands: Notothenia rossii, Champsocephalus gunnari, Dissostichus eleginoides – Current distribution and status of stocks

Guy Duhamel, Patrice Pruvost, Michel Bertignac, Nicolas Gasco & Mélyne Hautecoeur
The large-scale trawl exploitation targeting virgin stocks of marbled notothenia (Notothenia rossii) off the Kerguelen Islands occurred after the discovery by the Soviet Union scouting fishing fleet of the fishing grounds in the early 1970’s. The fishery shifted to icefish (Champsocephalus gunnari) and grey notothen (Lepidonotothen squamifrons) when overexploitation on the shelf and surrounding banks resulted in the sharp decline in the catches of marbled notothenia. The creation of the French EEZ in 1978 closed...

Dietary comparison of pike-perch, Sander lucioperca (Linnaeus, 1758) and catfish, Silurus glanis Linnaeus, 1758 in Sidi Salem dam reservoir (Tunisia)

Houda Djait, Lilia Bahri-Sfar, Houcine Laouar, Néjiba Missaoui & Oum Kalthoum Ben Hassine
Sidi Salem dam (Northern Tunisia) hosts two introduced predatory fish species: the pike-perch, Sander lucioperca, and the catfish, Silurus glanis. We examined the stomach contents of 162 S. glanis and 547 S. lucioperca specimens sampled along two years from four different stations in the dam reservoir. Both species were found to feed mainly on teleost fishes, with the cyprinids Sarmarutilus rubilio and Scardinius erythrophthalmus as the main preys. One species of crustacean and insect larvae...
