Although similar to N. furcifer, N. christyi and N. buescheri in having an elongate body, strongly emarginate caudal fin, and vertical fins partly covered with scales, this species is distinguishable from them by its small orbit, light grayish-brown coloration of body, dorsal fin lacking a submarginal dark band, 37 longitudinal body scales, 8 gill rakers on lower limb of the 1st gill arch, and a long pointed snout. Neolamprologus is a genus of the family Cichlidae Neolamprologus longicaudatus sp. nov. in Lake Tanganyika, one of the Great Rift Valley (Figs. 1, 2) lakes in the central east Africa. Lake Tanganyika is famous for its remarkable endemism seen in the Neolamprologussp. "Kavalla" Konings and Dieckhof ,f cichlid fishes, and the genus Neolamprologus is also 1992:150, fig. (Milima Island, Zair e) . endemic to the lake. Neolamprologus is the largest Holotype.

Aggressive Behaviours of Territorial Cichlid Fishes Against Larger Heterospecific Intruders
African Swdy Monographs, 15(2): 69-75, October 1994 69 AGGRESSIVE BEHAVIOURS OF TERRITORIAL CICHLID FISHES AGAINST LARGER HETEROSPECIFIC INTRUDERS Masanori KOHDA Laboratory of Animal Sociology, Department of Biology, Faculty of Science, Osaka City University Sima Keita l\1BOKO Centre de Recherche en Sciences Nature/les, Station d'Uvira ABSTRACT Aggressive behaviours at nesting territories of cichlid fishes were observ ed in Lake Tanganyika. Subject fishes were Neolamprologus toae, Tropheus moorii, Ophthalmotilapia nasutus, Limnotilapia dardennii and Petrochromis po/yodon. They attacked and repelled various sized heterospecific fishes from the territories. Against much larger intruders. the fishes quickly approached and pecked them. The larger fishes never con ducted counter-attack, and left the territories. Such pecking beha\iour was regarded as a kind of attack, but greatly different from attacks in interspecific territorialities of cichlids re ported hitherto, which are usually organized in size-dependent dominance relationships. This paper discusses the domination of the nesting territory owners in a context of 'sym metry' of territoriality. Key Words: Territorial behaviour: Domination; Nesting territory: Territorial mosaic. INTRODUCTION Tropical waters usually include large numbers of fish species. In such habitats. fishes develop a variety of interspecific relationships (Lowe-McConnell, 1987; Hori, 1987, 1991; Kohda. 199la, 1991b). among which interspecific territoriality is common and has been studied by many authors (Miller, 1978; Kohda. 1993). In terspecific feeding territories of herbivorous damselfishes or cichlid fishes, as well as intraspecific ones, are arranged in a territorial mosaic (Keenleyside. 1979) and are usually organized by size-dependent dominance relationships (Myrberg, 1972: Keenleyside, 1979; Kohda, 1991, 1993; Kohda & Yanagisawa. -

www.nature.com/scientificreports OPEN Genome sequences of Tropheus moorii and Petrochromis trewavasae, two eco‑morphologically divergent cichlid fshes endemic to Lake Tanganyika C. Fischer1,2, S. Koblmüller1, C. Börger1, G. Michelitsch3, S. Trajanoski3, C. Schlötterer4, C. Guelly3, G. G. Thallinger2,5* & C. Sturmbauer1,5* With more than 1000 species, East African cichlid fshes represent the fastest and most species‑rich vertebrate radiation known, providing an ideal model to tackle molecular mechanisms underlying recurrent adaptive diversifcation. We add high‑quality genome reconstructions for two phylogenetic key species of a lineage that diverged about ~ 3–9 million years ago (mya), representing the earliest split of the so‑called modern haplochromines that seeded additional radiations such as those in Lake Malawi and Victoria. Along with the annotated genomes we analysed discriminating genomic features of the study species, each representing an extreme trophic morphology, one being an algae browser and the other an algae grazer. The genomes of Tropheus moorii (TM) and Petrochromis trewavasae (PT) comprise 911 and 918 Mbp with 40,300 and 39,600 predicted genes, respectively. Our DNA sequence data are based on 5 and 6 individuals of TM and PT, and the transcriptomic sequences of one individual per species and sex, respectively. Concerning variation, on average we observed 1 variant per 220 bp (interspecifc), and 1 variant per 2540 bp (PT vs PT)/1561 bp (TM vs TM) (intraspecifc). GO enrichment analysis of gene regions afected by variants revealed several candidates which may infuence phenotype modifcations related to facial and jaw morphology, such as genes belonging to the Hedgehog pathway (SHH, SMO, WNT9A) and the BMP and GLI families. -

Towards a Regional Information Base for Lake Tanganyika Research
RESEARCH FOR THE MANAGEMENT OF THE FISHERIES ON LAKE GCP/RAF/271/FIN-TD/Ol(En) TANGANYIKA GCP/RAF/271/FIN-TD/01 (En) January 1992 TOWARDS A REGIONAL INFORMATION BASE FOR LAKE TANGANYIKA RESEARCH by J. Eric Reynolds FINNISH INTERNATIONAL DEVELOPMENT AGENCY FOOD AND AGRICULTURE ORGANIZATION OF THE UNITED NATIONS Bujumbura, January 1992 The conclusions and recommendations given in this and other reports in the Research for the Management of the Fisheries on Lake Tanganyika Project series are those considered appropriate at the time of preparation. They may be modified in the light of further knowledge gained at subsequent stages of the Project. The designations employed and the presentation of material in this publication do not imply the expression of any opinion on the part of FAO or FINNIDA concerning the legal status of any country, territory, city or area, or concerning the determination of its frontiers or boundaries. PREFACE The Research for the Management of the Fisheries on Lake Tanganyika project (Tanganyika Research) became fully operational in January 1992. It is executed by the Food and Agriculture organization of the United Nations (FAO) and funded by the Finnish International Development Agency (FINNIDA). This project aims at the determination of the biological basis for fish production on Lake Tanganyika, in order to permit the formulation of a coherent lake-wide fisheries management policy for the four riparian States (Burundi, Tanzania, Zaïre and Zambia). Particular attention will be also given to the reinforcement of the skills and physical facilities of the fisheries research units in all four beneficiary countries as well as to the buildup of effective coordination mechanisms to ensure full collaboration between the Governments concerned. -

Breman2, Stephan Koblmüller6, Christian Sturmbauer6, Jos Snoeks1,2, Filip A. M. Volckaert1 & Tine Huyse1,2 The stunning diversity of cichlid fishes has greatly enhanced our understanding of speciation and radiation. Little is known about the evolution of cichlid parasites. Parasites are abundant components of biodiversity, whose diversity typically exceeds that of their hosts. In the first comprehensive phylogenetic parasitological analysis of a vertebrate radiation, we study monogenean parasites infecting tropheine cichlids from Lake Tanganyika. Monogeneans are flatworms usually infecting the body surface and gills of fishes. In contrast to many other parasites, they depend only on a single host species to complete their lifecycle. Our spatially comprehensive combined nuclear-mitochondrial DNA dataset of the parasites covering almost all tropheine host species (N = 18), reveals species-rich parasite assemblages and shows consistent host-specificity. Statistical comparisons of host and parasite phylogenies based on distance and topology-based tests demonstrate significant congruence and suggest that host-switching is rare. Molecular rate evaluation indicates that species of Cichlidogyrus probably diverged synchronically with the initial radiation of the tropheines. They further diversified through within-host speciation into an overlooked species radiation.
