Collection was done during the period from May 2001 to March 2005. Eight species were studied for morphometric measurements and ratios, cytogenetic patterns and protein polymorphism. Morphometric measurements taken included the total length (L), standard length (SL), depth (D), interorbital width (IOW), eye diameter (ED), peduncle length (PL) and peduncle depth (PD). Measurements and ratios revealed significant differences between members of the species collected at the two freshwater systems. The cytogenetic study revealed a chromosome complement of 2n= 56 for Hydrocynus species members and 2n= 42 for Alestes species members. Chromosomes were found to vary in structure within

  • A Guide to the Parasites of African Freshwater Fishes
    A Guide to the Parasites of African Freshwater Fishes Edited by T. Scholz, M.P.M. Vanhove, N. Smit, Z. Jayasundera & M. Gelnar Volume 18 (2018) Chapter 2.1. FISH DIVERSITY AND ECOLOGY Martin REICHARD Diversity of fshes in Africa Fishes are the most taxonomically diverse group of vertebrates and Africa shares a large portion of this diversity. This is due to its rich geological history – being a part of Gondwana, it shares taxa with the Neotropical region, whereas recent close geographical affnity to Eurasia permitted faunal exchange with European and Asian taxa. At the same time, relative isolation and the complex climatic and geological history of Africa enabled major diversifcation within the continent. The taxonomic diversity of African freshwater fshes is associated with functional and ecological diversity. While freshwater habitats form a tiny fraction of the total surface of aquatic habitats compared with the marine environment, most teleost fsh diversity occurs in fresh waters. There are over 3,200 freshwater fsh species in Africa and it is likely several hundreds of species remain undescribed (Snoeks et al. 2011). This high diversity and endemism is likely mirrored in diversity and endemism of their parasites. African fsh diversity includes an ancient group of air-breathing lungfshes (Protopterus spp.). Other taxa are capable of breathing air and tolerate poor water quality, including several clariid catfshes (e.g., Clarias spp.; Fig. 2.1.1D) and anabantids (Ctenopoma spp.). Africa is also home to several bichir species (Polypterus spp.; Fig. 2.1.1A), an ancient fsh group endemic to Africa, and bonytongue Heterotis niloticus (Cuvier, 1829) (Osteoglossidae), a basal actinopterygian fsh.

  • 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.

The project was conceived as the Slow Food Foundation and FAO independently manage various activities in Africa with different approaches, but in this case saw a common interest and mutually beneficial objectives. Given the distinctive features of the Slow Food Foundation’s approach to its activities in many countries of the Global South—in Africa, South America and Asia—and as a result of its common interest with the FAO regarding some activities in the agrifood area, there have been significant collaborative efforts in recent years. This project is a practical expression of the shared aims. To optimally coordinate activities, attention has focused on West Africa, in particular 4 countries: Sierra Leone, Guinea Bissau, Mali and Senegal. West Africa has some of the poorest regions on the continent.

  • Introduction to Fisheries Management
    LECTURE NNOTE ON FIS 201 (2Units) INTRODUCTION TO FISHERIES MANAGEMENT PREPARED BY DR (MRS) IKENWEIWE N. BOLATITO AQUACULTURE AND FISHERIES DEPARTMENT UNIVERSITY OF AGRICULTURE,ABEOKUTA 1 INTRODUCTION ICTHYOLOGY is the scientific study of fish. Fish, because of the possession of notochord belong to the phylum chordata. They are most numerous vertebrates. About 20,000 species are known to science, and compare to other classes, aves 98,600species and mammals 8600species, reptiles 6,000 spandamphibians 2,000species.Fish also in various shape and forms from the smallest niamoy17mmT.L the giant whale shark that measures 15m and heights 25 tonnes. Fish are poikilothermic cold blooded animals that live in aquatic environment Most fish , especially the recent species, have scales on their body and survive in aquatic environment by the use of gills for respiration. Another major characteristic of a typical fish is the presence of gill slits which cover the gills on the posterior. (1) FISH TAXONOMY. Everyone is at heart a taxonomist whether by virtue or necessity or because of mere curiosity. 1. To know/identify the difference component in a fish population. That is to name and arrange. 2. To study the population dynamics in a population. (Number of each species in a population.) 3. Important in fish culture propagation – to know the species of fish that is most suitable for culture. 4. To exchange information to people in other parts of the world living known that both are dealing on the same species. 5. Reduce confusion as same Latin word generally acceptable worldwide are used while vernacular names differ form one location to another.
