Records of the eels Kaupichthys atronasus (Chlopsidae), Phyllophichthus xenodontus (Ophichthidae), and Gorgasia preclara (Congridae) from the Red Sea

David G. Smith, Sergey V. Bogorodsky & Ahmad O. Mal
Kaupichthys atronasus Schultz, 1953 is recorded from two specimens from Egypt and Saudi Arabia. Phyllophichthus xenodontus Gosline, 1951 is recorded from two specimens collected from Egypt. Geographic variation in this species is discussed. Gorgasia preclara Böhlke & Randall, 1981 is recorded from a photograph taken of a live individual at Dahab, Egypt.

Three new records of Gobiidae from Malta with morphology, colouration and identification of the smallest known juveniles of two small gobiid speciesof two small gobiid species

Marcelo Kovačić, Juan Jose Bonello & Julian Evans
Individuals of small juvenile gobies, some of them just 10 mm long, were collected during a study on infralittoral cobble bed fauna around the Maltese Islands between July and September 2011. These represent the first records of three gobiid species for Malta, including Gobius couchi Miller & El Tawil, 1974 and the smallest known juveniles of Millerigobius macrocephalus (Kolombatović, 1891) and Zebrus zebrus (Risso, 1827). Morphology and colouration, including diagnostic features and photographs, are provided...

Aspects qualitatifs et quantitatifs de l’alimentation de Clarias buettikoferi (Siluriformes ; Clariidae) dans la forêt des marais Tanoé-Ehy (Côte d’Ivoire)

Yao Aristide Konan, Mamadou Bamba & Tidiani Koné
L’alimentation du poisson-chat Clarias buettikoferi Steindachner, 1894 a été étudiée dans la forêt des marais Tanoé-Ehy (Côte d’Ivoire). Les poissons ont été capturés mensuellement à l’aide de filets verveux et de filets maillants entre mars 2012 et février 2013. Au total, 208 poissons ont été capturés, de longueur standard et de poids variant entre 90 mm et 260 mm LS et entre 7,3 g et 132 g, respectivement. L’indice de vacuité général était de 14,4%,...

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...

First record and new depth range extension of the curled Picarel, Centracanthus cirrus (Sparidae) from the Sea of Marmara, Turkey

M. Levent Artüz & Nerdin Kubanç
The presence of the Centracanthus cirrus Rafinesque, 1810 in the West part of the Sea of Marmara, on 1000 m depth, was reported on the base of the capture of one female of 116 mm standard length. The fish was caught using a beam-trawl deployed on the coast of Uçmakdere (Sea of Marmara). This is the first reliable record in the Sea of Marmara and new depth extension for this species.

Possible collapse of reef shark populations in remote coral reef ecosystems in the Coral Sea (Western Pacific)

Eric Clua & Thomas Vignaud
The decline of meso-predators such as reef sharks is a concern as such species can have important ecological roles in maintaining reef ecosystem resilience. Two field trips conducted in August 2010 and November 2011 to the Chesterfield archipelago (Coral Sea) allowed us to assess the abundances and average sizes of medium-bodied Carcharhinidae with a specific focus on grey reef shark (Carcharhinus amblyrhynchos), through fishing (46 hours of accumulated effort) and underwater visual censuses (25 hours...

Morphological and histological data on the structure of the lingual toothplate of Arapaima gigas (Osteoglossidae; Teleostei)

François J. Meunier, Paulo M. Brito & Maria Eduarda C. Leal
The pirarucu, Arapaima gigas (Osteoglossidae) has a basibranchial toothplate that supports a great density of teeth and helps the food transfer from the oral cavity towards the oesophagus. The lingual teeth appear early during ontogeny of the hyoid and branchial skeleton. On the basibranchial toothplate the teeth are closely set but without any connection, contrary to the “coalesced teeth”. The lingual teeth are 4 mm long and 1.0 to 1.5 mm wide; they are constituted...

Range extension and re-description of Synagrops argyreus (Perciformes, Acropomatidae)

Artem M. Prokofiev & Werner Schwarzhans
Since its first description by Gilbert and Cramer (1897) (originally as Melanostoma argyreum), Synagrops argyreus was considered to be endemic to Hawaii. New data from the southern Indian Ocean in the Madagascar Channel and the Coral and Tasman Seas reveal a considerable wider geographical distribution of the species, adding to the growing number of pseudoceanic species with a wide distribution pattern in the Indo-Pacific.

Âge, croissance et reproduction du sar tambour Diplodus cervinus cervinus (Sparidae) des côtes de l’Est algérien

Farid Derbal & M. Hichem Kara
L’âge, la croissance et la reproduction du sar tambour, Diplodus cervinus cervinus (Lowe, 1838), ont été étudiés sur les côtes de l’Est de l’Algérie, à partir de 190 spécimens. En utilisant la méthode scalimétrique, nous avons pu identifier 13 groupes d’âge dans la population échantillonnée (9,8 < Lt < 52,7 cm ; 19 < Mt < 2100 g). Les paramètres de la croissance sont Lt∞ = 68,83 cm, K = 0,105 et t0 = –0,747,...

First record of Dactylopterus volitans (Dactylopteridae) in the Eastern English Channel

Kélig Mahé, Eric Foucher, Romain Elleboode, Samuel P. Iglésias & Alain Tetard
This is the first record of the flying gurnard Dactylopterus volitans (Linnaeus, 1758) in the Eastern English Channel. One specimen was caught on 24 November 2011 in the Bay of Seine. It measured 47 cm and weighed 840 g. Based on the sagittal otolith, this specimen was 4 or 5 years old. Another specimen has been observed in the Western English Channel by a fisherman of Granville on 10 October 2012.

Domestication level of the most popular aquarium fish species: is the aquarium trade dependent on wild populations?

Fabrice Teletchea
Aquarium fish trade has strongly increased in the past decades to become one of the most popular hobbies globally. Historically, all aquarium fish traded were wild-caught. Then, an increasing number of fish species have been produced in captivity. The main goal of the present study is to apply the concept of domestication level to the hundred most popular aquarium fish species in Europe and North America. The levels of domestication of freshwater aquarium fish species...

Spinal deformities in Amazon sailfin catfish Pterygoplichthys pardalis (Siluriformes: Locariidae), an introduced fish in the Palizada River (Southeastern Mexico)

Armando T. Wakida-Kusunoki, Luis E. Amador-Del Ángel & Claudia Moreno-Miranda
The Amazon sailfin catfish Pterygoplichthys pardalis (Castelnau, 1855) is an introduced species in the Palizada River (Southeastern Mexico). Since 2008, we performed investigations on the populations of this species. In June and November 2012, and in February and March 2013, we captured ten specimens, which displayed kyphosis and scoliosis of the spinal column, diagnosed by high resolution X-ray. This is the first report of axial skeleton deformities in the genus Pterygoplichthys.

Revision of the Pelvicachromis taeniatus-group (Perciformes), with revalidation of the taxon Pelvicachromis kribensis (Boulenger, 1911) and description of a new species

Anton Lamboj, Daniela Bartel & Emiliano Dell’Ampio
Sixty-six specimens of seven populations of the Pelvicachromis taeniatus-group are compared and examined, using molecular and anatomical-morphological methods as well as coloration patterns. Accordingly, the taxon P. taeniatus is restricted to populations from Benin and Nigeria. For most populations from Cameroon the old taxon P. kribensis is revalidated and specimens from the Wouri River are described as a new species, P. drachenfelsi sp. nov. Species diagnosis is based on molecular characters and coloration patterns –...
