Occasional Papers of the Museum of Zoology University of Michigan
February, 2006 OCCASIONAL PAPERS OF THE MUSEUM OF ZOOLOGY UNIVERSITY OF MICHIGAN CHILOGLANIS PRODUCTUS, A NEW SPECIES OF SUCKERMOUTH CATFISH (SILURIFORMES:MOCHOKIDAE) FROM ZAMBIA By Heok Hee Ngl and Reeve M. Bailey1 ABSTRACT.- Chiloglaizis productus, new species, is described from the Lunzua River, which drains into the southern tip of Lake Tanganyika in Zambia. It is easily distinguished from congeners in having a color pattern consisting of a pale midlateral stripe on a purplish gray body and without any other distinct pale patches or bands, and by the nature of its sexual dimorphism in caudal fin shape: males have a produced caudal fin (vs. diamond shaped, forked or trilobate in males of otlicr sexually dimorphic congeners). Kcy words: Chiloglaninae, Lunzua River, Lake Tanganyika INTRODUCTION Suckermouth catfishes of the genus Chiloglanis Peters, 1868 are endemic to Africa and are easily recognized by a sucker or oral disc formed by the enlarged upper and lower lips and a naked body. A total of 45 nominal species of Chiloglanis have been recognized (Seegers, 1996). During an ichthyological survey in Zambia, the second author obtained material from the Lunzua River, tributary to the southern tip of Lake Tanganyika that is clearly different from described species. The description of this material as Chiloglanis productus, new species, forms the basis of this study. METHODS AND MATERIALS Measurements were made point-to-point using a dial caliper to the nearest 0.1 mm following the methods of Ng (2004) with the following addition: oral disc width is the widest transverse distance between the extremities of the oral disc. -

United Republic of Tanzania
1 United Republic of Tanzania GEOGRAPHY, CLIMATE AND POPULATION The United Republic of Tanzania consists of the mainland and Zanzibar, which is made up of the islands Unguja and Pemba. Its total area is 945 090 km2. The country is bordered in the north by Kenya and Uganda, in the east by the Indian Ocean, in the south by Mozambique and in the west by Rwanda, Burundi, the Democratic Republic of the Congo and Zambia. The Indian Ocean coast is some 1 300 km long, while in the northwest there are 1 420 km of shoreline on Lake Victoria, in the centre-west there are 650 km of shoreline on Lake Tanganyika and, in the southwest, 305 km of shoreline on Lake Malawi. The terrain comprises plains along the coast, a plateau in the central area, and highlands in the north and south. The northeast border with Kenya is dominated by Mt. Meru and Mt. Kilimanjaro. Southwards is the Central Plateau reaching elevations above 2000 m. The mountain range of the Southern Highlands separates the Eastern plateau from the rest of the country. Land cover is dominated by woodland, grassland and bushland which account for about 80 percent of the total land area. Cultivable area is estimated to be 40 million ha, or 42 percent of the total land area. In 2002, 13 percent of the cultivable area was actually cultivated, comprising 4 million ha of arable land and 1.1 million ha under permanent crops (Table 1). The climate varies from tropical along the coast to temperate in the highlands. -

(2010): “Hydrocynus vittatus is known from most of sub-Saharan Africa from Senegal to Ethiopia, and south to South Africa.” “Central Africa: Hydrocynus vittatus is found throughout the Congo River basin [Angola, Burundi, Cameroon, Central African Republic, Democratic Republic of the Congo, South Sudan, Tanzania, Zambia]. In Lower Guinea, it is found in the Cross and Sanaga basins [Cameroon, Nigeria].” 1 “Eastern Africa: This species is known from Lake Tanganyika [Burundi, Democratic Republic of the Congo, Tanzania, Zambia] and major affluent rivers, including Malagarasi river [Tanzania], as well as Lake Albert [Democratic Republic of the Congo, Uganda] and Murchison Nile [Uganda], Lake Turkana [Kenya] [Seegers et al. 2003] and Lake Rukwa [Tanzania]. It is also present in the Lower Shire river [Malawi, Mozambique], Rufigi and Ruaha Rivers [Tanzania]. According to Hopson and Hopson (1982) in the Turkana Basin [Kenya, Uganda, South Sudan] this species is principally riverine and ecological changes in the lake level have tended to inhibit incursions of H. vittatus into the lake. However, an erroneous identification by Worthington and Ricardo (1936) for H. forskahlii is also possible. In the latter case H. vittatus most likely does not occur in Kenya [Seegers et al. -

Box 1994 Dar es Salaam Summary The presence of wetlands in the various protected areas in Tanzania (national parks, game reserves, controlled areas and the Ngorongoro Special Conservation Area) is described. The value of tourism in wetlands and the problems of wildlife in wetlands is discussed. Recommendations for the management of wetlands in reserves emphasises the necessary involvement of people who live adjacent to these areas and are affected by management decisions. Introduction The reserved areas in Tanzania arc summarised in TabIc I. In Table 2 the conservation status of large freshwater wetlands of the Zaire River drainage and Lakes Tanganyika, Nyasa, and Victoria are shown. Table 3 shows the wetlands of the eastern Rift Valley and the eastern drainage -system. There are 56 controlled areas where wildlife exists alongside human activities such as farming and fishing. Laws governing wetlands If a wetland is within a national park or game reserve, then its management falls under the control of the Director of Wildlife. Hydropower dams are controlled by the Tanzanian Electricity Company (TANESCO). In some areas, for example the Bahi Swamps, the wildlife is under the control of the Director of Wildlife but the wetland is managed by the villagers. 61 Wetlands of Tanzania Table 1 Protected areas of Tanzania and their status, with reference to wetland conservation Protected areas Area Wetland system Features of significance (km2) National parks Arusha 137 Riverine, lacustrine, Ngurudoto Crater. -

Subsistence Fish Farming in Africa: a Technical Manual

Liberia, ASUR, 2006 - © Yves Fermon ii Subsistence fishfarming in Africa Subsistence fishfarming in Africa OBJECTIVES OF THE MANUAL Ö The objective of this manual is to explain how to build facilities that produce ani- mal protein — fish — using minimal natural resources and minimal external supplies. These fish are being produced for the purpose of subsistence. Ö It is possible to produce edible fish in a short time and at a low cost in order to to compensate for a lack of animal protein available in a community and to do so sustai- nably. However, facilities must be adapted to the environmental context. This manual is a guide for: ¾ Program managers and their technical teams; ¾ Managers at headquarters who are monitoring program success. This manual covers: Ö The different stages of starting of a «fish farming» program As soon as teams arrive on the ground, they must evaluate the resources available, the needs of the population, and existing supplies. This assessment is followed by the technical work of ins- talling fish ponds. When this is done, the next stage is to manage and monitor the ponds and the production of fish. Ö Constraints on field workers The determination of whether fish farming is appropriate in a particular location and if so, of which type, will depend upon many environmental variables.
