From the early 1940s up the late 1980s, several morphology-based classifications were proposed [8][9][10][11]. However, since our publication in 2006, which summarized and analyzed available morphological characters [12], several molecular phylogenies were published [13][14][15][16][17], but, to my best knowledge, no new morphological characters have been described. The aim of the present study is to try to demonstrate that the tremendous development of aquaculture in the
ABSTRACT: Systematics is traditionally based on morphological characters to both define species and establish classifications. In the past decades, partly due to the advent of molecular biology, traditional systematics has declined while molecular systematics has tremendously increased. This results in that fewer funding are generally provided to traditional systematics, particularly for searching new morphological characters. Aquaculture, the farming of aquatic animals, has increased exponentially in the past decades, providing today more than half of fish consumed worldwide, and is expected to continue to rise. Aquaculture requires controlling the life cycle of the farmed fish in captivity, including the rearing of early life stages. Therefore, by coupling systematics and aquaculture, it could be possible to bring new funds and facilities to the former to study the early life stages of numerous fish species and to the latter it would offer a conceptual framework to perform comparative ontogeny. Together, this could help improving our knowledge on the early life stages that could be useful for both taxonomists and zootechnicians.

However, a recent molecular-based phylogenetic analysis showed that Gaidropsarus ensis and G. argentatus , which represent species of Onogadus in the sense of Svetovidov (1986a), form a separate clade among the species of Gaidropsarus analysed (Francisco et al. 2014). This reinforces our assumption tthat Onogadus should be recognised as a separate genus. ABSTRACT: Reconstruction of fossil teleost faunas can provide important information on palaeoenvironments, palaeogeography and evolution, and otoliths are particularly useful for that purpose. Here we present an otolith-based fish fauna from the middle Miocene of the Eastern Paratethys, i.e. the Karagaily section of the Mangyshlak Peninsula in Western Kazakhstan, and report on the accompanying nannoplankton, foraminifera, molluscs and ostracods. A total of 30 teleost species are described and figured, including ten new species: Alosa paulicrenata n.sp., Morone? bannikovi n.sp., Centracanthus pobedinae n.sp., Genyonemus? karagiensis n.sp., Trewasciaena
suzini n.sp., Parablennius
prokofievi n.sp., Aphia djafarovae n.sp., Neogobius udovichenkoi n.sp., Ponticola zosimovichi n.sp., Pomatoschistus bunyatovi n.sp. Nannoplankton and gastropods indicate a Konkian (late Badenian, early Serravallian) age for this fish assemblage. The dominance of Gadidae and Gobiidae, together with the composition of the nannoplankton, indicates an inner-neritic to coastal environment with high productivity. The Konkian fish fauna of the Eastern Paratethys shows a high degree of autonomy relative to approximately contemporaneous fish faunas from the Central Paratethys and other European basins. This confirms that the Konkian was a time of limited faunal exchange between the Central and Eastern Paratethys, while a marine connection may have persisted between the Central Paratethys and the northern Mediterranean. We conclude that the fish fauna reported here records an early endemic development in the Eastern Paratethys during the middle Miocene (Konkian). The disappearance of Bregmacerotidae and Gonostomatidae (Bonapartia) during the preceding stage of the Karaganian and the first appearance of Palimphemus minusculoides in the Konkian are important biostratigraphical markers.Article · Aug 2015 +1 more author...ABSTRACT: A new microstomatid oceanic species, Nansenia boreacrassicauda spec. nov., is described from the temperate and sub-arctic Atlantic Ocean. The new species is part of the “stubby caudal peduncle” group and includes the northernmost record of any Nansenia species close to the Arctic Circle. The new species is putatively most similar to the Mediterranean Nanse-nia iberica, distinguished by a smaller caudal peduncle length/depth ratio, a smaller predorsal distance, more gill rakers, a different lateral line scale type and distribution. Extended Nansenia species distributions and specimens that show ex-tralimital characters in relation to previous works are presented, addressing the current problematic taxonomic issues prev-alent in pencil smelts and closely related genera. The new species is described due to increased collecting and taxonomic efforts off Greenland and is not necessarily related to ocean temperature changes. Full-text · Article · Sep 2015}
