    Evolution and speciation in the Haplochromis (Pisces, Cichlidae) of Lake Victoria (2021)
    In:  http://aquaticcommons.org/id/eprint/16966 | 4230 | 2021-02-20 20:50:59 | 16966 | National Fisheries Resources Research Institute, Uganda

    Description: The species flock of cichlid fishes in Lake Victoria comprises two endemic Tilapia, about seventy endemic Haplochromis and four endemic monotypic genera with strong aplochromis affinities. In addition there are six Haplochromis and one monotypic genus with a somewhat wider distribution; however, only one of these species, the nilotic H. multicolor, extends beyond the Edward-Victoria drainage basins. The smaller Haplochromis species flocks in Lakes Edward and Kivu are closely related to that of Victoria, but even including these species the whole complex shows less taxonomic, morphological and ecological diversity than the flocks of Haplochromis and Haplochromis-like species in Lake Nyasa.

    Fish remains from the Mumba Cave, Lake Eyasi (2021)

    Description: Through the courtesy of Dr. U. LEHMANN of the Geologisches Staatsinstitut, Hamburg, I have been able to examine the fish remains collected froPl the Mumba Cave by Professor KOHL-LARSEN'S 1938 expedition. Fish remains were obtained from the third (Homo sapiens; late Stone Age) and fifth ('Africanthropus'; Stillbay) strata, and comprise vertebrae, neurocranial fragments and fin spines. The majority are slightly mineralized (as measured by their hardness and weight) and are lightly coloured, but a small proportion are dark brown in colour and are more heavily mineralized. Fossils from anyone depth usually show some intergradation in hardness and coloration, but specimens in the "pale-soft" category predominate. In general, the bones are well preserved and consequently a high proportion (over 98%) can be identified generically. But, since specific characters are not clearly reflected in any of the elements preserved, it is impossible to name the species present.

    On two species of cichlid fishes from the Malagarazi River (Tanganyika), with notes on the pharyngeal apophysis in species of the Haplochromis group (2021)
    East African Fisheries Research Organisation | Jinja, Uganda

    Description: The material described in this paper was collected during a survey of the fish and fisheries of the Malagarazi River and swamps carried out in August and September, 1952, by members of the East African Fisheries Research Organisation and the Inland Fisheries Officer (Kigoma). Previous records of Cichlid fishes from the Malagarazi River have been published by David (1937) and Poll (1946 and 1948). These included Haplochromis burtoni (Ganither)'and H. malagaraziensis David from the upper reaches of the river, and Tilapia karomo Poll from the delta. The present collection was made at Uvinza and Iragala on the open river and at Katare on one of the numerous swamps. Besides the one new species described below, Horei burtoni and H. horei were collected at Irangala, and a species of Serranochromis at Uvinza and Katare. Two apparently new species of Haplochromis were collected in all three areas and will be described at a later date.

    A collection of fishes from the Aswa river drainage system, Uganda (2021)
    In:  http://aquaticcommons.org/id/eprint/19668 | 4230 | 2020-11-09 03:37:58 | 19668 | National Fisheries Resources Research Institute, Uganda

    Description: The collection described below was made in April 1960 by the Uganda Game and Fisheries Department, and came from tributaries of the upper Aswa river about 20 miles north of Soroti. The Aswa rises on high ground in the western region of Karamoja and joins the Nile about 30 miles north of Nimule. For part of its course the river flows close to Lake Kyoga and some of its tributaries in this area arise near streams draining into Kyoga. Thus, it is an area of some zoogeographical interest since, like Lake Albert, it can be looked upon as an incursion of the Nile into a zone characterized by the large number of endemic or geographically restricted species occurring in bodies of water isolated both from one another and from the Nile.

    Description: Fish-remains collected from deposits at Ishango (Lake Edward) and the Semliki valley by Dr. J. DE HEINZELIN'S 1960 expedition, have increased considerably our historical knowledge of East African fishes. The collections are of especial value since their temporal range extends over the entire Pleistocene period, a time when the great lakes of Africa were undergoing extensive topographical changes and their faunae were subject to the vicissitudes of changing climate and hydrography. Indeed, the Pleistocene may be looked upon as a critical phase in the evolution of the present-day East African fish-fauna from an earlier and possibly pan-African type. Many taxonomists and evolutionists have been attracted by the biogeographical problems which these lakes present. But, attempts to explain the often curious distribution of families and genera within the area have been hampered by the lack of an adequate palaeontological background.

    The fishes of Uganda (2021)

    Description: The fishes of Uganda have been subject to considerable study. Apart from many purely descriptive studies of the fishes themselves, three reports have been published which deal with the ecology of the lakes in relation to fish and fisheries (Worthington (1929a, 1932b): Graham (1929)). Much of the literature is scattered in various scientific journals, dating back to the early part of thecentury and is difficult to obtain in Uganda. The more recent reports also are out of print and virtually un obtainable. The purpose of this present survey isto bring together the results of these many researches and to present, in the light of recent unpublished information, an account of the taxonomy and biology of the many fish species which are to be found in the lakes and rivers of Uganda.Particular attention has been paid to the provision of keys, so that most of the Fishes may be easily identified.
