An Analysis of Primary and Secondary Production in Lake Kariba in a Changing Climate

Ndebele-Murisa PhD, Biodiversity and Conservation Biology Department, University of the Western Cape Analysis of temperature, rainfall and evaporation records over a 44-year period spanning the years 1964 to 2008 indicates changes in the climate around Lake Kariba. Mean annual temperatures have increased by approximately 1.5oC, and pan evaporation rates by about 25%, with rainfall having declined by an average of 27.1 mm since 1964 at an average rate of 6.3 mm per decade. At the same time, lake water temperatures, evaporation rates, and water loss from the lake have increased, which have adversely affected lake water levels, nutrient and thermal dynamics. The most prominent influence of the changing climate on Lake Kariba has been a reduction in the lake water levels, averaging 9.5 m over the past two decades. These are associated with increased warming, reduced rainfall and diminished water and therefore nutrient inflow into the lake. The warmer climate has increased temperatures in the upper layers of lake water, the epilimnion, by an overall average of 1.9°C between 1965 and 2009. -
The Freshwater Herring of Lake Tanganyika Are the Product of a Marine Invasion Into West Africa
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Open Marine Archive Marine Incursion: The Freshwater Herring of Lake Tanganyika Are the Product of a Marine Invasion into West Africa Anthony B. Wilson1,2¤*, Guy G. Teugels3, Axel Meyer1 1 Department of Biology, University of Konstanz, Konstanz, Germany, 2 Zoological Museum, University of Zurich, Zurich, Switzerland, 3 Ichthyology Laboratory, Royal Museum for Central Africa, Tervuren, Belgium Abstract The spectacular marine-like diversity of the endemic fauna of Lake Tanganyika, the oldest of the African Great Lakes, led early researchers to suggest that the lake must have once been connected to the ocean. Recent geophysical reconstructions clearly indicate that Lake Tanganyika formed by rifting in the African subcontinent and was never directly linked to the sea. Although the Lake has a high proportion of specialized endemics, the absence of close relatives outside Tanganyika has complicated phylogeographic reconstructions of the timing of lake colonization and intralacustrine diversification. The freshwater herring of Lake Tanganyika are members of a large group of pellonuline herring found in western and southern Africa, offering one of the best opportunities to trace the evolutionary history of members of Tanganyika’s biota. Molecular phylogenetic reconstructions indicate that herring colonized West Africa 25–50MYA, at the end of a major marine incursion in the region. Pellonuline herring subsequently experienced an evolutionary radiation in West Africa, spreading across the continent and reaching East Africa’s Lake Tanganyika during its early formation. While Lake Tanganyika has never been directly connected with the sea, the endemic freshwater herring of the lake are the descendents of an ancient marine incursion, a scenario which may also explain the origin of other Tanganyikan endemics. -

Parasites of Coral Reef Fish: How Much Do We Know? with a Bibliography of Fish Parasites in New Caledonia
Belg. J. Zool., 140 (Suppl.): 155-190 July 2010 Parasites of coral reef fish: how much do we know? With a bibliography of fish parasites in New Caledonia Jean-Lou Justine (1) UMR 7138 Systématique, Adaptation, Évolution, Muséum National d’Histoire Naturelle, 57, rue Cuvier, F-75321 Paris Cedex 05, France (2) Aquarium des lagons, B.P. 8185, 98807 Nouméa, Nouvelle-Calédonie Corresponding author: Jean-Lou Justine; e-mail: [email protected] ABSTRACT. A compilation of 107 references dealing with fish parasites in New Caledonia permitted the production of a parasite-host list and a host-parasite list. The lists include Turbellaria, Monopisthocotylea, Polyopisthocotylea, Digenea, Cestoda, Nematoda, Copepoda, Isopoda, Acanthocephala and Hirudinea, with 580 host-parasite combinations, corresponding with more than 370 species of parasites. Protozoa are not included. Platyhelminthes are the major group, with 239 species, including 98 monopisthocotylean monogeneans and 105 digeneans. Copepods include 61 records, and nematodes include 41 records. The list of fish recorded with parasites includes 195 species, in which most (ca. 170 species) are coral reef associated, the rest being a few deep-sea, pelagic or freshwater fishes. The serranids, lethrinids and lutjanids are the most commonly represented fish families. Although a list of published records does not provide a reliable estimate of biodiversity because of the important bias in publications being mainly in the domain of interest of the authors, it provides a basis to compare parasite biodiversity with other localities, and especially with other coral reefs. The present list is probably the most complete published account of parasite biodiversity of coral reef fishes. -

Whose Commons? Fishermen, Developmentalists and Conservationists on Lake Malawi Anne Ferguson Department of Anthropology Michiga
WORKSHOP IN POLITICAL THEORY AND POLICY ANALYSIS 513 NORTH PARK INDIANA UNIVERSITY BLO DMINGTON, IN 47408-3895 U S > Whose Commons? Fishermen, Developmentalists and Conservationists on Lake Malawi by i Anne Ferguson Department of Anthropology Michigan State University Bill Derman Department of Anthropology . Michigan State University , Richard Mkandawire j Department of Rural Development Bunda College of Agriculture, University of Malawi September 15, 1990 Paper prepared for the First International Association for the Study of Common Property: "Designing Sustainability on the Commons", Duke University: September 3-7-30, 1990 Draft. Please do not cite without agreement of | the authors I. Introduction Fish from Lake Malawi are a major source of animal protein for large numbers of people in Malawi and Mozambique, two of Sub- Saharan Africa's poorest countries. It is estimated that fish, supplied by a dynamic and diverse small-scale African fishing industry, contribute seventy percent of animal protein consumed by Malawians per year (Alimoso et al. 1990). In this paper we briefly discuss the scale and social organization of fishing and what we have learned about use rights in the southern and central portions of Lake Malawi. We propose that the open access fishing which exists in these areas has not significantly harmed fish stocks to date, although problems may be emerging. An equal, if not greater, threatjto the fish, fishing and the ecology of Lake Malawi than that posed by open access small-scale fishing originates from developmentalists— internal and external actors advocating large-scale, capital intensive exploitation of the fish and the development of an international tourism industry. -

FINAL REPORT EXTERNAL EVALUATION of the Research, Monitoring and Development Project of Fisheries in the Cahora Bassa Reservoir – Phase II 2007-2010 Republic of Mozambique Ministry of Fisheries JUNE , 2010 Final Report: External Evaluation of the Research, Monitoring and Development Project of Fisheries in the Cahora Bassa Reservoir – Phase II EXECUTIVE SUMMARY I. INTRODUCTION The Research, Monitoring and Development Project of the Fisheries in the Cahora Bassa Reservoir – Phase II (a.k.a., Phase II or Project in this Evaluation) is a collaborative effort between ICEIDA and the Ministério das Pescas (MP, or Ministry of Fisheries) of the Government of Mozambique (GoM). Within MP, the Instituto Nacional de Investigação Pesqueira (IIP) is the implementing institution and is responsible for promoting scientific management of fisheries resources in Mozambican waters. ICEIDA commissioned an independent Evaluation of the Phase II Project in June 2010. This report presents the findings of the Evaluation Team. The Phase II Project was formulated in 2006 and implemented in 2007 as a complementary continuation of the very successful Phase I, conducted 2003–2005 that principally concerned the kapenta fishery and capacity development at Cahora Bassa. The objective of Phase II was stated as: The Project is a research-based project aimed at producing management options for the three fisheries, the semi-industrial, the Artisanal and the sport fisheries on the Cahora Bassa reservoir with the objective of minimizing fisher conflict and at the same time optimizing the harvest from Cahora Bassa. The specific objectives were defined in the Project Document (PD) as: 1. Strengthening the infrastructure and research facilities of the IIP delegation in Songo; 2. -
