A deepwater threadfin, Polydactylus longipes (Perciformes: Polynemidae), from Vanuatu: new record from the South Pacific

Hiroyuki Motomura, Patrice Pruvost & Romain Causse
A specimen of Polydactylus longipes, previously known only from three type specimens from the Philippines, was collected off Vanuatu at a depth of 300-360 m. This specimen is the first record of P. longipes from outside the Philippines, being an approximately 5000 km southeastward range extension from the type locality. The depth of capture revealed P. longipes to be the deepest occurring member of the family. Apparent morphological changes due to allometric growth are also...

Morphological identification of two sympatric species of Trichiuridae, Aphanopus carbo and A. intermedius, in NE Atlantic

Manuel Biscoito, João Delgado, José A. González, Sérgio Stefanni, Víctor M. Tuset, Eduardo Isidro, Antonio M. García-Mederos & Dalila Carvalho
The black scabbardfish has been subjected to a commercial fishery in the waters of the archipelago of Madeira for more than 150 years, which is probably the oldest deep-sea commercial fishery in the world. Over this period the presence of two sympatric species (Aphanopus carbo Lowe, 1839 and A. intermedius Parin, 1983) in the area has been ignored, mainly due to the difficulty in separating the two species using external morphological characters. The need for...

First record of two deep-water fish, Bellottia apoda and Symphurus ligulatus in the Turkish Mediterranean Sea

M. Emilia Gramitto, Mehmet C. Deval & İsmet Saygu
Bellottia apoda Giglioli, 1883 and Symphurus ligulatus (Cocco, 1844) are recorded for the first time in the Eastern Mediterranean (Bay of Antalya, Turkey). Meristic and morphometric characters of the specimens are given. These findings extend eastward the distribution range of B. apoda and confirm the presence of S. ligulatus in the Levant Basin of the Mediterranean Sea.

Is the African armoured searobin (Peristedion cataphractum, Peristediidae) stock off the south Sicily and North African coasts a “unit stock”?

Teresa Bottari, Giandomenico Nardone, Paola Rinelli & Sergio Ragonese
Distribution, abundance, biological traits and growth of Peristedion cataphractum L., 1758 coming from two areas of the Strait of Sicily were analysed. The two investigated areas correspond to the north (A-area) and south (B-area) of the midline located between South Sicily and North Africa. Both published and new elaborated parameters were estimated from data gathered in autumnal experimental bottom trawl surveys; the surveys in the B-area, in particular, were carried out between 1997 and 2004....

Circulation and hydrography over the Kerguelen Plateau

Young-Hyang Park & Frédéric Vivier
The Kerguelen Plateau is the largest near-meridional submarine plateau lying across the Antarctic Circumpolar Current (ACC), affecting significantly the large-scale circulation and pathways of the different water masses across the plateau. This has important implication not only for the local primary productivity and marine ecosystem, but also for the meridional overturning circulation of the Southern Ocean. We give here a short review of the circulation and hydrography as well as the ACC transport over and...

History of whaling, sealing, fishery and aquaculture trials in the area of the Kerguelen Plateau

Guy Duhamel & Richard Williams
The exploitation of marine resources on the Kerguelen Plateau only began in 1790 (18th century) after the discovery of the northern Kerguelen Islands in 1772. Salted fur seal (Arctocephalus gazella) skins was the first product to be commercialized by Nantucket (USA) and London (UK) ship-owners, mainly on the Kerguelen Islands, and by the early 19th century the seal colonies were decimated. The sealing gangs shifted to extracting oil from the blubber of elephant seals (Mirounga...

Biodiversity of the benthos off Kerguelen Islands: overview and perspectives

Nadia Améziane, Marc Eléaume, Lenaïg G. Hemery, Françoise Monniot, Arzhela Hemery, Mélyne Hautecoeur & Agnès Dettaï
The Kerguelen Plateau possesses a very diverse benthic fauna. Over the years, the number of species recorded from the Kerguelen has substantially increased. From 172 species reported by Arnaud (1974), the total number of species has increased dramatically to 735 (Jouventin et al., 1996) and then to 960 in the present study. This area is particularly vulnerable to human activities and global climate change. Coastal benthic ecosystems are likely to be heavily impacted. However, these...

Description of a new deep-sea Lantern Shark Etmopterus viator sp. nov. (Squaliformes: Etmopteridae) from the Southern Hemisphere

Nicolas Straube, Guy Duhamel, Nicolas Gasco, Jürgen Kriwet & Ulrich K. Schliewen
Lantern sharks (Etmopterus spp.) constitute a regular by-catch in longline fisheries conducted along the north-eastern Kerguelen Plateau shelf in depths of 600 to 1700 m. Kerguelen lantern sharks are morphologically close to E. granulosus, E. sp. B, South African E. cf. granulosus, and E. litvinovi. However, molecular phylogenetic analyses support the hypothesis that they represent a distinct cryptic species, which is in line with morphological characters separating the species from its Southern Hemisphere congeners. The new species is...

Foraging habitats of top predators, and Areas of Ecological Significance, on the Kerguelen Plateau

Mark A. Hindell, Mary-Anne Lea, Charles-André Bost, Jean-Benoît Charrassin, Nick Gales, Simon Goldsworthy, Brad Page, Graham Robertson, Barbara Wienecke, Malcolm O’Toole & Christophe Guinet
Avian and mammalian predators play a key role in the Kerguelen Plateau ecosystem, both with respect to structuring the marine community and its response to anthropogenic influences, such as climate change and commercial fisheries. A powerful way to determine regions of particular ecological importance is to identify Areas of Ecological Significance (AES): regions that are utilized by multiple predator species. Such concentrations of foraging activity are indicative of enhanced primary and/or secondary productivity. These are...

Performance across extreme environments: comparing waterfall climbing among amphidromous gobioid fishes from Caribbean and Pacific Islands

Heiko L. Schoenfuss, Takashi Maie, Sandy M. Kawano & Richard W. Blob
Amphidromous gobioid fishes have colonized streams on tropical and subtropical volcanic islands across the globe. Such streams are often characterized by steep gradients, high velocity currents, and even waterfalls as in-stream obstacles; however, the ability to climb waterfalls has evolved in many goby species, allowing juveniles returning from the ocean to penetrate upstream reaches. Past studies of Hawaiian gobioid fishes have identified two functionally differ - ent climbing techniques that were characterized by differing kinematics:...

A review of distribution, field observations and precautionary conservation requirements for sicydiine gobies in Australia

Brendan C. Ebner, Paul A. Thuesen, Helen K. Larson & Philippe Keith
The tropical Indo-Pacific is considered the centre of sicydiine goby diversity. Nevertheless, these amphidromous gobies have only occasionally been recorded in Australia, and this probably relates to the existence of limited suitable habitat (perennial streams that drain steep coastal mountain ranges and enter the sea via poorly developed estuaries). We provide new records of the distribution of sicydiine gobies within Australia, and review the Australian biogeography of the group to confirm at least seven species...

A goby-fry fishery in the northern Colombian Pacific Ocean

Gustavo A. Castellanos-Galindo, Gian Carlo Sanchez, Beatriz S. Beltrán-León & Luis Zapata
Migrations between freshwater and marine environments are a common strategy among gobies of the Sicydiinae sub-family. Sicydiinae post-larvae occur in high density to the extent of supporting artisanal fisheries. Here, we document for the first time in the tropical eastern Pacific Ocean (Colombia), an artisanal fishery based on sicydiine post-larvae (Sicydium salvini) returning to relatively short and steep rivers of the coast. The migration and harvesting is comparable to that of sicydiines elsewhere in the...

Fishes of São Tomé – Results of the expeditions of Fernando Frade (1954) and Fernando Correia da Costa (1955)

Armando J. Almeida & Maria Judite Alves
This paper presents data on the fishes collected during two field missions in the coastal waters of São Tomé Island (Gulf of Guinea, eastern-central Atlantic Ocean) promoted by Junta de Investigações do Ultramar, Portugal in 1954 and 1955. 57 fish species were identified; they belong to 32 currently valid families.

A taxonomic review of Satanoperca (Teleostei: Cichlidae) from French Guiana, South America, with description of a new species

Sven O. Kullander
The new species Satanoperca rhynchitis occurs in French Guiana in the Oyapock, Approuague, Comté, Kourou, Sinnamary and Iracoubo river drainages. It is distinguished from congeneric species in particular by lower meristics and a longer snout, probably also by red lips in life. Samples of Satanoperca from Amapá state in Brazil fall into two groups, one probably representing the Amazonian S. jurupari, and the other resembling S. rhynchitis but with shorter snout. Species assignation of Amapá...

Resorption of scales in Atlantic salmon (Salmo salar) during its anadromous migration: a quantitative study

Adnane Kacem, Jean-Luc Baglinière & François J. Meunier
Resorption processes in the scales of Atlantic salmon, during its anadromous migration are known since 1935, but have never been quantified. In fact, the ellipsoid form of the ascending salmon scale resorbs into an irregular highly deformed shape in spawning salmon. The aim of this study is to quantify the changes of both anterior and posterior scale areas using image analysis techniques. Salmon scales were sampled taking into account the sex and sea age of...

Scorpaenopsis rubrimarginatus, a new species of scorpionfish from Réunion, southwestern Indian Ocean (Teleostei: Scorpaenidae)

Ronald Fricke, Patrick Durville & Thierry Mulochau
The scorpionfish Scorpaenopsis rubrimarginatus n. sp. is described based on a single specimen from 80 m depth off Réunion, southwestern Indian Ocean. The new species is characterised within the Scorpaenopsis cotticeps lineage, which comprises small and short-snouted species with the upper opercular spine divided into two or more points (two points in S. rubrimarginatus), by a combination of the following characters: 16 pectoral-fin rays, 23 lateral-line scales, 42 scales in longitudinal series on body, the...

Histological study of the median lingual dental plate of the Cretaceous fish †Palaeonotopterus greenwoodi (Teleostei: Osteoglossomorpha) from the Kem-Kem beds, Morocco

François J. Meunier, Didier Dutheil & Paulo M. Brito
We describe the histology of the lingual dental plate of an extinct Notopteridae, †Palaeonotopterus greenwoodi, from the Cenomanian Kem-Kem Beds in Morocco. The lingual dental plate is bulky. Its regular and more or less smooth crushing surface does not exhibit any teeth externally. The plate is composed of several superimposed layers of side-by-side teeth. The teeth are attached to each other by a small amount of cellular bony tissue that may contain some vascular canals....

Morphological and genetic variations of Diplodus vulgaris along the Tunisian coasts

Myriam Kaouèche, Lilia Bahri-Sfar, Ibtissem Hammami & Oum Kalthoum Ben Hassine
In order to characterize populations of Diplodus vulgaris (Geoffroy St.-Hilaire, 1817) along the Tunisian coasts and to test the prospective role of geographical barrier of the Siculo-Tunisian Strait, we performed a study of morphological and genetic variability of samples collected in six sites distributed on each side of the Strait. Two types of morphological descriptors, 25 truss elements and six complementary conventional linear measurements, and genetic markers (allozymes of four enzyme systems) were used. Multivariate...

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...

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.

Invasive Carassius spp. in the Tiber River basin (Umbria, Central Italy): population status and possible interactions with native fish species

Antonella Carosi, Lucia Ghetti & Massimo Lorenzoni
The purpose of the research was to analyse the distribution, abundance and growth of Carassius spp., a taxon which includes non-native species introduced into the water bodies of the Umbrian portion of the Tiber River basin during the late 1980s. Additionally, the study estimated the relative weight for Barbus tyberinus, Squalius lucumonis and Sarmarutilus rubilio to investigate the presence of competitive interactions between Carassius spp. and these native species that characterize the middle and lowland...
