Révision critique d’un catalogue des types de poissons du Muséum national d’Histoire naturelle – Familles des Triacanthidae, Balistidae et Monacanthidae

Monique Beaunier, Martine Desoutter & Patrice Pruvost
Critical revision of catalogue of types of fishes in Museum national d’Histoire naturelle. Family Triacanthidae, Balistidae and Monacanthidae. This catalogue is dedicated to three families of the order Tetraodontiforms: the Triacanthidae, the Balistidae and the Monacanthidae. These families are mainly present in tropical seas. The MNHN type specimens for these groups were published by Y. Le Danois in 1961. The latter work bears many errors and was not completely respectful of the International Code of...

Spatiotemporal patterns in marine fish and cephalopods communities across scales: using an autoregressive spatiotemporal clustering model. A study of fish and cephalopods of the Eastern English Channel

Katyana A. Vert-pre, Thomas Trancart & Eric Feunteun
In marine ecology, spatial and temporal fish community structure is important to understand ecosystem’s responses to anthropogenic and environmental factors. Although spatial distribution patterns and fish time series of abundance have been studied in the past, little research has addressed the impact of spatial scale on mapping spatiotemporal patterns. To achieve this goal, the first step is to develop a method describing spatiotemporal communities statistically. At three spatial resolutions, from 1043 km2 to 522 km2,...

Occurrence of Sebastes mentella (Scorpaeniformes: Sebastidae) off the Galician coast (NW Spain) (North-eastern Atlantic)

Olaya Fernández-Zapico, Juan Carlos Arronte & Susana Ruiz-Pico
The capture of a mature male of Sebastes mentella off the Galician coast, northern Spain is reported. This record represents the most southerly record for this species in the north-eastern Atlantic. Its presence could be a case of vagrancy from the Irminger Sea related to the reproduction migrations of this species.

Hasan Fazli, Gholamreza Daryanabard, Abdolrassoul Salmanmahiny, Shahram Abdolmaleki, Gholamali Bandani & Mohammad Ali Afraei-Bandpei
This paper examines the changes in biomass and condition index in relation to stock enhancement of Kutum (Rutilus frisii kutum) in Iranian waters of the Caspian Sea during 1991-2011. Over this period, the condition factor of female and male Kutum showed decreasing trends. The average condition factor declined from 1.48 in 1991-1992 to 1.29 in 2010-2011 for females and from 1.40 in 1991-1992 to 1.20 in 2010-2011 for males. The instantaneous coefficient of natural mortality...

Current genetic status of common carp (Cyprinus carpio L.) introduced into Tunisian reservoirs

Manel Louati, Lilia Bahri-Sfar, Klaus Kohlmann & Oum Kalthoum Ben Hassine
In order to enhance and develop inland fisheries and to create exploratory ichthyic stocks in reservoirs, the introduction of freshwater fishes in Tunisia began since the 1960s. However, stocking programs are usually conducted without any following assessment of the potential success of the exercise. Within the context of studying the genetic status of introduced populations, this paper describes the genetic variation of two domesticated varieties of common carp, scaly and mirror, introduced into five Tunisian...

Molecular evidence for the paraphyly of Pseudancistrus sensu lato (Siluriformes, Loricariidae), with revalidation of several genera

Raphaël Covain & Sonia Fisch-Muller
The genus Pseudancistrus is widely distributed in rocky, fast-flowing habitats of rivers draining all sides of the Guiana Shield and the northern slope of the Brazilian Shield. Initially diagnosed as having an “interoperculum” weakly evertible and lacking elongate odontodes, the definition of Pseudancistrus was subsequently expanded to include species with long, evertible cheek odontodes. Within Pseudancistrus sensu lato were included the already available genera Guya­nancistrus and Lithoxancistrus. To evaluate the relevance of such a grouping,...

A new species of amphidromous goby, Stiphodon alcedo, from the Ryukyu Archipelago (Gobiidae: Sicydiinae )

Ken Maeda, Takahiko Mukai & Katsunori Tachihara
A new goby species, Stiphodon alcedo , is described from 27 specimens collected in Okinawa and iriomote islands of the ryukyu archipelago, Japan. This species can be distinguished from its congeners by having a pointed, but not filamentous, first dorsal fin in males, nine soft-rays in the second dorsal fin, 15-17 rays in the pectoral fin, the number of teeth, and unique sexually dimorphic colouration. The new species is considered to have recently colonised the...

Impact of parasitism by nematodes on gonadal anatomy of Pagellus erythrinus (L.)

Nassima Saadi, Jean-Paul Trilles, Rachid Amara & Zouhir Ramdane
Nematode larvae (stages 3 and 4) infect various marine teleost fish. 297 specimens of Pagellus erythrinus (Teleostei: Sparidae) from the east coast of Algeria were examined for their parasitic nematodes between November 2015 and April 2017. Five nematode species were collected and identified: Hysterothylacium aduncum (Rudolphi, 1802), H. fabri (Rudolphi, 1819), H. sp., Cucullanus cirratus Müller, 1777 and Philometra filiformis (Stossich, 1896). Among them, three species (H. fabri, C. cirratus and P. filiformis) are reported for the first time in...

A new species and three new records of gobiid fishes from the Red Sea

Sergey V. Bogorodsky, Marcelo Kovačić & John E. Randall
Tomiyamichthys dorsostigma is described as a new species of goby from two specimens collected in the Gulf of Aqaba. It was first identified as T. fourmanoiri Smith, 1959, known from one specimen from Madagascar. It differs in having a longer head, the penultimate dorsal soft ray longest, longer paired fins, and in colour pattern. T. dorsostigma is more similar to another closely related species, T. smithi (Chen & Fang, 2003), differing in colour pattern and...

A first checklist of gobies from Crete with ten new records

Marcelo Kovačić, Marin Miletić & Nafsika Papageorgiou
The checklist of gobiids from Crete includes 17 species. The published data on gobies from Crete have so far been scarce. Ten species are the new findings from the present research. Two species, Corcyrogobius liechtensteini and Gammogobius steinitzi, from the north coast of Crete, represent the first finding of these species outside the north-western Mediterranean and the Adriatic Sea. It is expected that the actual gobiid biodiversity of Crete is much higher.
