Checklist of the marine fishes from metropolitan France

Philippe Béarez, Patrice Pruvost, Eric Feunteun, Samuel P. Iglésias, Patrice Francour, Romain Causse, Jeanne De Mazieres, Sandrine Tercerie & Nicolas Bailly
A list of the marine fish species occurring in the French EEZ was assembled from more than 200 references. No updated list has been published since the 19th century, although incomplete versions were available in several biodiversity information systems. The list contains 729 species distributed in 185 families. It is a preliminary step for the Atlas of Marine Fishes of France that will be further elaborated within the INPN (the National Inventory of the Natural...

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...

Comparison of feeding apparatus and feeding intensity of the European sardine (Sardina pilchardus) off Morocco in two Atlantic upwelling areas with different seasonal activity

Kenza Ouakka, Ahmed Yahyaoui, Hakim Mesfioui, Salah El Ayoubi & Jilali Bensbai
This study investigates the feeding intensity and the morphology of the feeding apparatus (gill rakers) of the European sardine Sardina pilchardus (Walbaum, 1792) in two hydro-dynamical contrasting areas of the eastern boundary upwelling system off Morocco. North, one area is characterized by a summer upwelling while South, the other area is more productive with a strong and almost permanent upwelling. Fish from both areas differ in their feeding intensity, fish condition and gill raker number...

CHIPS: A database of historic fish distribution in the Seine River basin (France)

Sarah Beslagic, Marie-Christine Marinval & Jérôme Belliard
The evolution of freshwater fish distribution and long term change in the composition of fish assemblages in rivers are currently the subject of various ecological studies. These studies usually focus on a relatively short range of time, rarely exceeding the last few years. However, this interval is far too short to understand in what extent human societies impact their environment. In order to study interactions between human activities and rivers and their fish assemblages over...

Rym Ennouri, Sami Mili & Lassaad Chouba
L’objectif de cette étude est de comparer les niveaux de contamination en métaux (Cd, Pb, Hg, Cu et Zn) d’une espèce benthique, le rouget de vase (Mullus barbatus), et une d’espèce pélagique, la sardinelle (Sardinella aurita) du golfe de Tunis. L’accumulation saisonnière des cinq éléments considérés a été suivie dans le muscle, le foie, les branchies, le cerveau et les gonades durant l’année 2006. Pour les deux espèces étudiées, le site préférentiel d’accumulation du Cd...

First record of Carolines parrotfish (Calotomus carolinus) and king angelfish (Holacanthus passer) around the Clipperton Atoll-La Passion Island (North-Eastern Tropical Pacific)

Eric Clua & Serge Planes
A mission on the Clipperton atoll (Eastern Tropical Pacific) in August 2018 allowed the unprecedented capture and identification of an adult individual of Carolines parrotfish (Calotomus carolinus) and a juvenile of king angelfish (Holacanthus passer).

A redescription of Stiphodon pulchellus (Herre, 1927) (Gobiidae: Sicydiinae)

Ken Maeda, Tetsuo Yoshino & Katsunori Tachihara
Stiphodon pulchellus (Herre, 1927) is redescribed based on 29 specimens collected in the Philippines. In addition, a neotype is designated using a specimen collected by Herre near the type locality (Dumaguete, Negros Oriental) and identified by him. Stiphodon olivaceus Watson & Kottelat, 1995 is considered to be a junior synonym of S. pulchellus. Despite being strikingly similar to Stiphodon imperiorientis, S. pulchellus can be distinguished by the size, number, and arrangement of black spots on...

L’âge de Coryphaena hippurus a été estimé par otolithométrie en se basant sur l’examen des microstries journalières de la sagitta. Au total, 120 otolithes ont été extraits de juvéniles collectés sur les côtes tunisiennes pendant la campagne de pêche 2005 (août à décembre). La longueur à la fourche des échantillons est comprise entre 24 et 65 cm. Le nombre d’accroissements journaliers varie de 53 à 230 chez les femelles et de 62 à 239 chez...

Redescription and phylogenetic position of the fossil killifish †Carrionellus diumortuus White from the Lower Miocene of Ecuador (Teleostei: Cyprinodontiformes)

Wilson J.E.M. Costa
†Carrionellus diumortuus from the Lower Miocene of Loja, southern Ecuador, is the type species of †Carrionellus, the only American cyprinodontiform genus uniquely containing fossil species. It was first considered as a member of the cyprinodontid tribe Cyprinodontini, a group comprising extant taxa geographically restricted to North and Middle America, but recently it has been tentatively placed in the Neotropical family Anablepidae. †Carrionellus diumortuus is herein redescribed on the basis of examination of the type series....

Dispersal of land-locked larval Ryukyu-ayu, Plecoglossus altivelis ryukyuensis, in the Fukuji Reservoir, Okinawa Island

Tatsuya Kawakami & Katsunori Tachihara
The dispersal of larval land-locked ryukyu-ayu, Plecoglossus altivelis ryukyuensis , which originated from an amphidromous form on amami-oshima island, was investigated from November 2000 to april 2001 in the freshwater Fukuji reservoir. a total of 232 larvae were collected at three stations at different distances from the mouth of the San- numata river. They were most abundant at the station closest to the San-numata river (Station1; 76.3% of total catch) and their distribution in the...

Influence of salinity on larval development of Sicyopterus lagocephalus (Pallas, 1770) (Gobioidei)

Céline Ellien, Pierre Valade, Jérôme Bosmans, Laura Taillebois, Nils Teichert & Philippe Keith
The widely distributed amphidromous goby Sicyopterus lagocephalus needs drastic change of habitat to fulfil its life-cycle: adults live and spawn in rivers, where eggs hatch in pro-larvae that have to reach the sea in a narrow temporal scale, to acquire marine characteristics, and begin their oceanic dispersal as planktonic larvae. Post-larvae return to rivers where they recruit and grow to the adult reproductive stage. Such a life-cycle raises the question of salinity changes between these...

Description of Melanotaenia salawati, a new species of rainbowfish (Melanotaeniidae) from Salawati Island, West Papua, Indonesia

Kadarusman, Sudarto, Jacques Slembouck & Laurent Pouyaud
Melanotaenia salawati n. sp. is described from 16 specimens collected at Salawati Island in the Raja Ampat Group lying immediately west of the Bird’s Head Peninsula in West Papua (Indonesia). Melanotaenia salawati is allied to M. batanta and M. fredericki. Melanotaenia batanta occurs in the central part of Batanta, an island just north of Salawati while M. fredericki is found on the westernmost portion of the Bird’s Head Peninsula. The trio have a similar general...

Reproductive parameters of the commercially exploited deep-water shark, Deania calcea (Centrophoridae)

Rafaela Barros Paiva, Ana Neves, Vera Sequeira & Leonel Serrano Gordo
Little information is available on the reproductive parameters of the commercially exploited deep shark Deania calcea (Lowe, 1839). Samples were obtained from deep-water longlines operating at depths around 1450 m in the Portuguese continental slope between September 2008 and July 2009. Both the male and female reproductive tracts were morphologically and histologically analysed. Females were more numerous than males, which may be related to possible sex segregation by depth/geographical area and/or fishermen preference for females...

First record of Polydactylus mullani (Polynemidae) from the Sultanate of Oman

Philippe Béarez, Sophie Kerneur & Hiroyuki Motomura
The Arabian blackspot threadfin, Polydactylus mullani, is an endemic species of the Arabian Sea, occurring along the Indian and Pakistani coasts. Its presence is recorded here for the first time at the south-western end of the Gulf of Oman. It could be that P. mullani was confused until now with Polydactylus sextarius as, until 2001, the former species was regarded only as a subspecies of the latter. However, P. mullani is not mentioned in any...

Bruno Chanet, Martine Desoutter & Sergey V. Bogorodsky
New collection of Egyptian sole, Solea aegyptiaca Chabanaud, 1927, from the Gulf of Suez (Red Sea, Egypt) confirm that this species is an anti-Lessepsian species. Migrations of teleostean fishes through the Suez Canal are discussed.

Note on the terminal nerve in chimaeroid fishes (Holocephali; Chimaeridae)

Martin Licht & Peter Bartsch
William Locy in 1905 on page 63 of his morphological and embryological account “On a newly recognized nerve connected to the fore-brain of selachians” mentions the “new nerve” or “supernumerary nerve” as it was termed before that time, tentatively traced upon dissection of the brain of Chimaera monstrosa. The terminal nerve as designated by Locy has never been mentioned for holocephalan fishes since, though new interest arose more recently with description of the terminal nerve...
