Maidenhead Aquatics Datasheet Lake
Maidenhead Aquatics Datasheet Lake Tanganyika Cichlids Lake Tanganyika is the deepest lake in Africa, and holds a very different assemblage of species to both Lake Malawi and Lake Victoria. There are many sub-groups of fish in this lake, all with different behaviour, environments and overall appearance. Tanganyikan cichlids also need hard, alkaline water with a pH around 8.0. They are usually must less aggressive and do not need to be overcrowded. However, they are not suitable for keeping in a community tank, and should not be mixed with the more boisterous Malawi's and Victorian's. Many species are small, so they can easily be kept in very small tanks, providing the water is kept free of pollution. SHELL DWELLERS Some species, such as many Neolamprologus species breed and take shelter in the shells of large aquatic snails. Many of these fish are fully grown at sizes of around 4cm (1%M), and can be kept alongside other larger species. For their size they are very aggressive and when breeding will often bite hands entering the tank for cleaning purposes. CAVE SPAWNERS Julidochromis, Variabilichromis, Altolamprologus and some Neolamprologus species spawn in crevices between rocks or in caves. Many of these form strong pair bonds, and have protracted parental care. Some species, for example, lay around 300 eggs. The young fry are guarded not only by both parents, but also by the previous generation of fry (older brothers and sisters). MOUTH BROODERS Some species, such as Tropheus and Xenotilapia are mouth brooders. Tropheus lay around 30 eggs which are kept in the female's mouth for around 30 days. -

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. -
Out of Lake Tanganyika: Endemic Lake Fishes Inhabit Rapids of the Lukuga River
355 Ichthyol. Explor. Freshwaters, Vol. 22, No. 4, pp. 355-376, 5 figs., 3 tabs., December 2011 © 2011 by Verlag Dr. Friedrich Pfeil, München, Germany – ISSN 0936-9902 Out of Lake Tanganyika: endemic lake fishes inhabit rapids of the Lukuga River Sven O. Kullander* and Tyson R. Roberts** The Lukuga River is a large permanent river intermittently serving as the only effluent of Lake Tanganyika. For at least the first one hundred km its water is almost pure lake water. Seventy-seven species of fish were collected from six localities along the Lukuga River. Species of cichlids, cyprinids, and clupeids otherwise known only from Lake Tanganyika were identified from rapids in the Lukuga River at Niemba, 100 km from the lake, whereas downstream localities represent a Congo River fish fauna. Cichlid species from Niemba include special- ized algal browsers that also occur in the lake (Simochromis babaulti, S. diagramma) and one invertebrate picker representing a new species of a genus (Tanganicodus) otherwise only known from the lake. Other fish species from Niemba include an abundant species of clupeid, Stolothrissa tanganicae, otherwise only known from Lake Tangan- yika that has a pelagic mode of life in the lake. These species demonstrate that their adaptations are not neces- sarily dependent upon the lake habitat. Other endemic taxa occurring at Niemba are known to frequent vegetat- ed shore habitats or river mouths similar to the conditions at the entrance of the Lukuga, viz. Chelaethiops minutus (Cyprinidae), Lates mariae (Latidae), Mastacembelus cunningtoni (Mastacembelidae), Astatotilapia burtoni, Ctenochromis horei, Telmatochromis dhonti, and Tylochromis polylepis (Cichlidae). The Lukuga frequently did not serve as an ef- fluent due to weed masses and sand bars building up at the exit, and low water levels of Lake Tanganyika. -

Depth Segregation and Diet Disparity Revealed by Stable Isotope Analyses
Hata et al. Zoological Letters (2015) 1:15 DOI 10.1186/s40851-015-0016-1 RESEARCH ARTICLE Open Access Depth segregation and diet disparity revealed by stable isotope analyses in sympatric herbivorous cichlids in Lake Tanganyika Hiroki Hata1*, Jyunya Shibata2,3, Koji Omori2, Masanori Kohda4 and Michio Hori5 Abstract Background: Lake Tanganyika in the African Great Rift Valley is known as a site of adaptive radiation in cichlid fishes. Diverse herbivorous fishes coexist on a rocky littoral of the lake. Herbivorous cichlids have acquired multiple feeding ecomorphs, including grazer, browser, scraper, and scooper, and are segregated by dietary niche. Within each ecomorph, however, multiple species apparently coexist sympatrically on a rocky slope. Previous observations of their behavior show that these cichlid species inhabit discrete depths separated by only a few meters. In this paper, using carbon (C) and nitrogen (N) stable isotope ratios as markers, we followed the nutritional uptake of cichlid fishes from periphyton in their feeding territories at various depths. Results: δ15N of fish muscles varied among cichlid ecomorphs; this was significantly lower in grazers than in browsers and scoopers, although δ15N levels in periphyton within territories did not differ among territorial species. This suggests that grazers depend more directly on primary production of periphyton, while others ingest animal matter from higher trophic levels. With respect to δ13C, only plankton eaters exhibited lower values, suggesting that these fishes depend on production of phytoplankton, while the others depend on production of periphyton. Irrespective of cichlid ecomorph, δ13C of periphyton correlated significantly with habitat depth, and decreased as habitat depth became deeper. -

Alloparental care in clownfishes Binu Varghese Marine Products Exports Development Authority, Kochi, India Parental care in clownfishes is well known, mouthing and fanning are the important behaviours apart from defending eggs from predators. They fan the egg mass using pectoral and caudal fins and thus provide necessary water movement to the densely packed clutch and thus help in faster removal of metabolic wastes (Figure 1). Clownfishes also remove unfertilized and unhealthy eggs from the clutch (egg batch).
