First insights into karyotype evolution within the family Mormyridae

Catherine Ozouf-Costaz, Jean-Pierre Coutanceau, Céline Bonillo, Laurent Belkadi, Yves Fermon, Jean-François Agnèse, Chantal Guidi-Rontani & Didier Paugy
The chromosomal diversity within six species of Mormyridae belonging to six different genera (Gnathonemus petersii, Marcusenius moorii, Ivindomyrus obdenboschi, Brienomyrus sp., Stomatorhinus walkeri and Petrocephalus microphthalmus) is investigated for the first time. These species have a conserved diploid chromosome number of 2n = 50 (except G. petersii 2n = 48) but different chromosome formulae, essentially involving pericentric inversions. C-banding has been used for the localization of heterochromatin. For a deeper interspecific comparison, several molecular markers...

Age, growth and mortality of the comber, Serranus cabrilla (Serranidae) in the Edremit Bay (NW Aegean Sea, Turkey)

Hatice Torku-Koç, Dilek Türker-Cakir & Jakov Dulčić
Age, growth and mortality of comber, Serranus cabrilla (L., 1785) were determined from 595 specimens collected on the northwestern Aegean coasts of Turkey from September 1997 to September 1998. Fork length ranged from 8.6 to 22.3 cm, while weight varied between 10.5 and 163.7 g. The von Bertalanffy growth equation was fitted on the basis of mean length-at-age data resulting in parameters values of L∞ = 33.6 cm (S.E. = 0.46), K = 0.111/y (S.E....

Étude du régime alimentaire des gobies du genre Pomatoschistus (P. microps et P. minutus) dans l’estuaire de la Gironde (France)

Stéphanie Pasquaud, Michel Girardin & Pierre Élie
L’étude du régime alimentaire des gobies du genre Pomatoschistus (P. minutus Pallas et P. microps Krøyer), dans l’estuaire de la Gironde, a été réalisée sur des échantillons formolés de l’année 2001, ceci en deux stations distinctes, une en zone oligohaline et l’autre en zone mésohaline. L’analyse des tubes digestifs a révélé que ces deux espèces basent essentiellement leur alimentation sur des proies pélagiques (copépodes) et sur l’hyperbenthos (stade mysis de crustacés, mysidacés, amphipodes, isopodes, poissons)....

Amanda Vaccani, Tatiane Fernández & Natalie Freret-Meurer
The present study reports the Hippocampus patagonicus Piacentino & Luzzatto, 2004 occurrence in shallow rocky reefs. We found two individuals in two different Guaíba Island beaches, Sepetiba Bay, Rio de Janeiro, Brazil. We recorded two adults with similar dimensions as reported in other studies with the same species. Usually, they are not found in shallow waters, but the present study reports them associated with rocky reefs less than one meter deep. This is the first...

Feeding close to fishing lights may be dangerous for the larvae of the smallest freshwater fish of Europe

Lambros Tsounis, Grigoria Vasilopoulou & George Kehayias
Economidichthys trichonis is the smallest teleostean of Europe and is inhabited Lake Trichonis (Greece). Previous investigation concerning the feeding of the dominant fish of this lake (Atherina boyeri) revealed that the use of fishing lights in the purse seine fishery of this species may result to its increased predation upon the larvae of E. trichonis, which come close to light. This study investigates the diet of these larvae, to understand why they approach to the...

A new underground water explorer

Frank Vasseur & Frédéric Santoul
The European catfish, Silurus glanis Linnaeus, 1758, has largely colonized lakes and rivers in Western and Southern Europe over the past 40 years. Recent studies have highlighted a high inter-individual variability in the species with strong adaptations in trophic ecology or habitat use. We report here the first and unexpected occurrence of one European catfish individual in underground waters. One young (estimated body size of 80 cm-1 m) catfish was observed 25 m deep in...

The lungs of extinct and extant coelacanths: a morphological and histological review

François J. Meunier, Camila Cupello, Marc Herbin, Gaël Clément & Paulo M. Brito
This review deals with recent studies on the lungs of fossil and extant coelacanths with classical techniques (dissections, photonic histology) and modern techniques (SEM, X-ray tomography). This recent knowledge allows to attest the homology between: i) the large bony plates of the calcified organ of extinct coelacanths and the small plates that surround the lung of the extant coelacanth Latimeria; ii) the (supposed functional) lung covered with bony plates of extinct coelacanths and the vestigial...

Differential production and uptake of dual vitellogenins in Japanese medaka (Oryzias latipes)

Naoshi Hiramatsu, Mihoka Inoue, Hiroki Ideuchi, Toshiaki Fujita, Haruna Amano, Takahiro Matsubara, Craig V. Sullivan & Akihiko Hara
Differential production and uptake of two forms of vitellogenin (VgA/B and VgC) was verified in serum and oocytes, respectively, of Japanese medaka (Oryzias latipes). The ratio of the two types of Vg (VgA/B:VgC) in the serum of females varied with reproductive stage (range ~2:1-8:1). In males exposed to waterborne E2 for various durations or at various dosages, the induced Vg ratios were fairly constant (~2.4:1-3.4:1) except that VgC alone was detected after a very short...

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...

Osteometry and size reconstruction of the Indian and Pacific Oceans’ Euthynnus species, E. affinis and E. lineatus (Scombridae)

Anaïs Marrast & Philippe Béarez
Two neritic species of scombrids (Euthynnus affinis and E. lineatus) from the Indo-Pacific and the Eastern Pacific are today classed as commercially important. They have long been exploited and are common finds on coastal archaeological sites. Size reconstruction from isolated bones is interesting for both biologists and archaeologists. In archaeology, these studies make it possible to highlight fishing strategies. Therefore, we built an osteometric model for these two species, using 31 specimens of E. affinis (FL: 274 mm...

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...
