    A new catfish from Sierra Leone Gordon Jon Howes Zoology Department, British Museum (Natural History), Cromwell Road, London SW7 5BD A collection of freshwater fishes from Sierra Leone made by Dr A. I. Payne contained three specimens of a previously undescribed dwarf catfish. At first sight these small fishes (33-5- 36 mm SL) were thought to be the juveniles of a Synodontis species, but closer examination showed many significant differences. Furthermore, dissection of two specimens revealed that they were adult females, having ripe ovaries. In overall morphology the new catfish appears closer to members of the Mochokidae sensu lato than to those of any other siluroid family, (see p. 168). The possibility that these fishes belonged to the dwarf mochokid genus Microsynodontis was dispelled when comparisons were made with species of that genus. MOCHOKIELLA gen. nov. Fishes of a small size with a shallow body (depth 25-5-27-9 of SL). Head broad (almost equal to its length) with dorsal profile sloped, snout rounded, ethmoid with narrow rostral process. Nostrils widely separated, the posterior situated midway between the anterior nostril and the orbital rim. Anterior nostril tubular. Mouth small, lower lip developed only at the corners of the mouth. Premaxillary teeth short and conical, in a broad patch. Dentary teeth like those on the premaxilla, set in a broad semi-crescentic band. Vomerine teeth absent. One pair of maxillary and two pairs of mandibular barbels. The maxillary barbel long, reaching to the tip of the cleithral process. Outer mandibular barbel extending to halfway along the cleithral process, the inner reaching to the base of the pectoral spine.

Imaobong Emmanuel Ekpo Department of Fisheries and Aquatic Environmental Management, University of Uyo, P. M. B. 1017, UYO – 520001, Akwa Ibom State – Nigeria. Corresponding address: [email protected] ; +234-8026073996. Abstract Fish species were investigated for 12 calendar months from March 2009 – February 2010 forthnightly using traps, gillnets and cast nets from three sampling stations in Ikpa River. Ornamental fish species were sorted out from the pooled samples. The findings revealed that of the 2307 fish specimens sampled, 1074 specimens made up of 38 species and 19 families were of indigenous ornamental fish. The highest contributing family in terms of number of species is Cichlidae (10 species) whereas Schilbeidae (593 specimens; 55.21%) is the highest contributor in terms of total number of specimens sampled. This is followed by Mochokidae and Mormyridae with 4 species each and Cichlidae with 158 specimens (14.70%). At the species level, the highest contributor is Physalia pellucida (577 specimens; 53.72%) and is followed by Erpetoichthys calabaricus (60 specimens; 5.59%). The least contributors were Heterobranchus bidorsalis, Periophthalmus barbarus and Pelvicachromis pulcher (1 specimen; 0.09%). Twelve families recorded only one species each. These great potentials of ornamental fish have been left unexploited and hence, undeveloped.

  • Molecular Investigations of the Diversity of Freshwater Fishes Across Three Continents
    Molecular Investigations of the Diversity of Freshwater Fishes across Three Continents by Malorie M. Hayes A dissertation submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Doctor of Philosophy Auburn, Alabama August 8, 2020 Keywords: Enteromius, Barbus, sub-Saharan Africa, phylogenetics, systematics, Pteronotropis, conservation genetics, Trichomycterus, Guyana Copyright 2020 by Malorie M. Hayes Approved by Jonathan W. Armbruster, Chair, Professor and Director Auburn University Museum of Natural History Department of Biological Sciences Jason E. Bond, Professor and Schlinger Chair in Insect Systematics University of California, Davis Scott R. Santos, Professor and Chair of the Department of Biological Sciences at Auburn University John P. Friel, Director of the Alabama Museum of Natural History Abstract Fishes are the most speciose vertebrates, and incredible diversity can be found within different groups of fish. Due to their physiological limitations, fish are confined to waters, and in freshwater fish, this is restricted to lakes, rivers, and streams. With a constrained habitat like a freshwater system, it can be expected that freshwater fish will show varying levels of diversity depending on a suite of characteristics. Within this dissertation, I examine the diversity of three fish groups: the speciose Enteromius of West Africa, the population genetic diversity of Pteronotropis euryzonus in Alabama and Georgia, and the unexpectedly species rich Trichomycterus from the Guyana highlands. I use molecular methods and geometric morphometrics to determine the systematics of the species and uncover the hidden diversity within their respective groups. When it comes to diversity, the small barbs of Africa are vastly understudied and require a taxonomic revision.

  • A Guide to the Parasites of African Freshwater Fishes
    A Guide to the Parasites of African Freshwater Fishes Edited by T. Scholz, M.P.M. Vanhove, N. Smit, Z. Jayasundera & M. Gelnar Volume 18 (2018) Chapter 2.1. FISH DIVERSITY AND ECOLOGY Martin REICHARD Diversity of fshes in Africa Fishes are the most taxonomically diverse group of vertebrates and Africa shares a large portion of this diversity. This is due to its rich geological history – being a part of Gondwana, it shares taxa with the Neotropical region, whereas recent close geographical affnity to Eurasia permitted faunal exchange with European and Asian taxa. At the same time, relative isolation and the complex climatic and geological history of Africa enabled major diversifcation within the continent. The taxonomic diversity of African freshwater fshes is associated with functional and ecological diversity. While freshwater habitats form a tiny fraction of the total surface of aquatic habitats compared with the marine environment, most teleost fsh diversity occurs in fresh waters. There are over 3,200 freshwater fsh species in Africa and it is likely several hundreds of species remain undescribed (Snoeks et al. 2011). This high diversity and endemism is likely mirrored in diversity and endemism of their parasites. African fsh diversity includes an ancient group of air-breathing lungfshes (Protopterus spp.). Other taxa are capable of breathing air and tolerate poor water quality, including several clariid catfshes (e.g., Clarias spp.; Fig. 2.1.1D) and anabantids (Ctenopoma spp.). Africa is also home to several bichir species (Polypterus spp.; Fig. 2.1.1A), an ancient fsh group endemic to Africa, and bonytongue Heterotis niloticus (Cuvier, 1829) (Osteoglossidae), a basal actinopterygian fsh.

MORITZ* AND K. E. LINSENMAIR Lehrstuhl fur¨ Tiero¨kologie und Tropenbiologie, Theodor-Boveri-Institut, Universita¨t Wurzburg,¨ Am Hubland, 97074 Wurzburg,¨ Germany (Received 2 May 2006, Accepted 6 February 2007) Brevimyrus niger is reported to breathe atmospheric air, confirming previous documenta- tion of air breathing in this species. Air is taken up by rising to the water surface and gulping, or permanently resting just below the surface, depending on the environmental conditions. # 2007 The Authors Journal compilation # 2007 The Fisheries Society of the British Isles Key words: elephantfishes; Osteoglossomorpha; weakly electric fish. The Mormyridae consists of 201 weakly electric fishes endemic to Africa (Nelson, 2006). They belong to the Osteoglossomorpha among which air-breathing behaviour is known from several families. All genera of the Osteoglossidae are able to breathe atmospheric air utilizing their swimbladder as a respiratory organ, i.e. Heterotis niloticus (Cuvier) (Luling,¨ 1977), Arapaima gigas (Schinz) (Luling,¨ 1964, 1977). Similarly, Pantodon buchholzi Peters (Schwarz, 1969), which is the only member of the Pantodontidae, and the members of the Notopteridae (Graham, 1997) are air-breathers. A close relative to the mormyrids, Gymnarchus niloticus Cuvier, the only member of the Gymnarchidae, is also well known to breathe air (Hyrtl, 1856; Bertyl, 1958). In the remaining two families within the Osteoglossomorpha air breathing has never been reported from the Hiodontidae (Graham, 1997) and only for a single species, Brevimyrus niger (Gunther),¨ within the Mormyridae (Benech & Lek, 1981; Bigorne, 2003).

EMJDs aim to foster cooperation between higher education institutions and academic staff in Europe and third countries with a view to creating centres of excellence and providing a highly skilled 21st century workforce enabled to lead social, cultural and economic developments. All EMJDs involve mandatory mobility between the universities in the consortia and lead to the award of recognised joint, double or multiple degrees. The SMART programme represents a collaboration among the University of Trento, Queen Mary University of London and Freie Universität Berlin.

  • Global Catfish Biodiversity 17
    American Fisheries Society Symposium 77:15–37, 2011 © 2011 by the American Fisheries Society Global Catfi sh Biodiversity JONATHAN W. ARMBRUSTER* Department of Biological Sciences, Auburn University 331 Funchess, Auburn University, Alabama 36849, USA Abstract.—Catfi shes are a broadly distributed order of freshwater fi shes with 3,407 cur- rently valid species. In this paper, I review the different clades of catfi shes, all catfi sh fami- lies, and provide information on some of the more interesting aspects of catfi sh biology that express the great diversity that is present in the order. I also discuss the results of the widely successful All Catfi sh Species Inventory Project. Introduction proximately 10.8% of all fi shes and 5.5% of all ver- tebrates are catfi shes. Renowned herpetologist and ecologist Archie Carr’s But would every one be able to identify the 1941 parody of dichotomous keys, A Subjective Key loricariid catfi sh Pseudancistrus pectegenitor as a to the Fishes of Alachua County, Florida, begins catfi sh (Figure 2A)? It does not have scales, but it with “Any damn fool knows a catfi sh.” Carr is right does have bony plates. It is very fl at, and its mouth but only in part. Catfi shes (the Siluriformes) occur has long jaws but could not be called large. There is on every continent (even fossils are known from a barbel, but you might not recognize it as one as it Antarctica; Figure 1); and the order is extremely is just a small extension of the lip. There are spines well supported by numerous complex synapomor- at the front of the dorsal and pectoral fi ns, but they phies (shared, derived characteristics; Fink and are not sharp like in the typical catfi sh.
