The folk knowledge of fish is described in detail for the two areas. The author identified 100 species from the Lllalaba River and 97 species from Lake Tanganyika. Songola fishermen n:nya subgroup) along the Lualaba (upper reaches of the Z'lire, formerly the Congo) River have lOB vernacular names and 12 inclusive folk categories of fish, consisting of six levels of categorization. There are 18 series of "growth fishe" fish which have two to four di fferent vernacular names according to their life-cycle stages. All the "growth fishes" of the Enya are large-sized fishes and their names change by growth size. The thresholds for the different names seem to be related to the mesh sizes of traditional fishing nets. Bwari fishermen of northern Lake Tanganyika have a simpler system of folk classification than the Songola-Enya. They have 79 vernacular' fish names and -1 inclusive folk categories, consisting of three levels. There are A "growth fishes". They were diverse in body size and a small clupeid ndagaa, one of the most. abundant and important fishes for the l.ake Tanganyika fishermen, has as many as four life-cycle stages that determine its market price. The difference in the folk knowledge of t,he fish between these two peoples might be understood by t.he difference in the composition of the fish fauna of the two areas; in Lake Tanganyika whi Ie small-sized cichl id species (called inclusi>'ely as .LENDA by the Bwari) are abundant., it is the ndaga8 that prevails in today's catch. A comparison of the fish names among 15 peoplcs of Central Africa suggested that fish nomenclatures of Bantu societies have little similarity between independent water systems. I found only two stems havin~ a universal distrilJulrion in Central Africa: .nJ·ik. for electric catfish and .sembe for lung-fish. Fishermen of Central Africa have an accurate and rather objective knowledge of fish on which they are dependent. As l'el, some of the fishes are regarded as sJlecial. Some nre regarded as tahoo, ot.hers used as charm medicine. lIaving an intermediate character hetween fish lIud ot.her creatures (bird or tree) and hllving anomalous features are good reasons to r'egard t.hem as speciaL Where do all these differences come from? In order to consider the problems concerning the comparative ecology and epistemology of African peoples more properly, we must. he equipped with a better knowledge on the environment (fallna and flora), I inguistics, and ethnography. Key Words: Ethnosciences, Folk classification, Freshwater fish, Lualaba River, Lake Tanganl'ika, Bembe, Bwari, Enya, Songola, Vira. 2 Fish I\nowled!{'! of Songola'" Bwari (Y. ANKF.I) \. Introduction 1.1 The pu I'pose and the methods of study This paper aims to describc thc folk knowledge of African freshwater fish for two groups of fishing people. one living along the Lualaba River and the other on the coast of Lake Tanganyika (Fig. 1). Relatively few works ha\'c been puhl ishpd concerning t.he el.lllloichl.hyoJogy (or the st.udy of the folk knowledge uf rish) dpspite today's flourishing folk biological stndies (1'01' example, GOSSf' , 1961, 1962; Morrill, 1967; Anclen,on, 1969; Ilulmer el ai., 1975; Akimichi, 1978). This study also comparps the folk classification systems between the Lualaba and Lake Tanganyika, two of the great waleI' systems in tropical Africa. Such a compal'ison will shed light on the relationship between the fish fauna, the folk knowledge of it, and the ecollomy dependent on African freshwater fish. Specimens of fish were collected in the research villages or bought at near'hy markets. They were shown to I' i shermen, when fresh, to get i II formation on the folk knowledge of them. They are then stored in the Laborat.ory of Animal Ecology (Facult.y or Scipnces, Kyoto University) using lahels from the 1979 expedition. Fish specimclIs 1'1'011 t.he Lualaba River were identified IIsing Bollienger (1909-1916) and ot.her referencp works (Nicholas & Griscom, 1937; Poll, 1957, 1!l;J9, 1967, 1971, 1973, 1976; Poll f< Gosse 1963; Gilnter, 1973; Gery, 1977; Banister & Bai ley, 1979), and revised by CI.OFFA 1-3 (Daget et aJ. 1980-). Specimens from Lake Tanganyika were identified using Poll (1953 and 1956) Rnd Brichard (1978). Drs. Kenji TAKA~lJRA and Kosaku YAMAOKA helped to identfy the species and rev ise t.he scientific names.

They are a fishln/{ sub~roup of the Songola, and are different from the famous Enya fisherml'n of Klsangani (Ankei, 1984). Supplementary information was obtained durin~ a four months' stay in 1983. For the purpose of comparison, i also collected vernacular fish names of two other sub~rollps of t.he Songola who live in areas remot.e from t.he Lualaba River: the Kuko and the Binja. The area on Lake Tan/{any i ka was on the northwestern shore of t.he lake. near Uv i ra and Baraka in the Sous-Region du Sud-Kivu.

Although there is no information extant for the B\~ari language, it is probable that it corresponds to so-called "kabwari" (J-56) of Guthrie (1967).

  • Artisanal Fisheries in the SE Brazilian Coast: Using Fisher Information Towards Local Management
    Artisanal fisheries in the SE Brazilian coast: using fisher information towards local management A. Begossi Nepam Unicamp, CP 6166, Campinas, S.P. 13081-970, Brazil Abstract Coastal artisanal fisheries in SE Brazil are located close to huge urban centers, such as Rio de Janeiro and São Paulo cities. Many of these fisheries are also adjacent to Atlantic Forest remnants. The growth of tourism, and associated recreational fishing, along with pollution in the coastal waters, increased the chances of impact on species and on artisanal fishing. Some fish species are located close to shore, such as species of Serranidae (groupers, such as Epinephelus and Mycteroperca) and seem vulnerable to the impact from fishing and from pollution. Other species, such as from the family Centropomidae (snooks, Centropomus spp.) are found in estuarine environments, and are also a target of recreational fishers, being subject to pollution coming from coastal rivers. In order to have more information on fishing for species of Serranidae and Centropomidae, I marked the fishing spots used by artisanal fisheries in different communities found in the SE Brazilian coast. The spots were marked using GPS Garmin III and V and Magellan. Maps of the fishing spots used to catch Serranidae and Centropomidae were drawn (103 fishing spots for groupers and 36 for snooks). Such maps are based on local fisher information, and they show the area used to fish the Serranidae and Centropomidae. Such data are important to designate areas for artisanal fisheries, and to evaluate the pressure on species of Serranidae and Centropomidae. Keywords: Centropomus, Epinephelus, grouper, Mycteroperca, fishing, Brazil, snook.

  • 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.
