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. -
A Review of On-Farm Feed Management Practices for North African Catfish (Clarias Gariepinus) in Sub-Saharan Africa
463 A review of on-farm feed management practices for North African catfish (Clarias gariepinus) in sub-Saharan Africa Thomas Hecht1 Department of Ichthyology and Fisheries Science Rhodes University, Grahamstown South Africa Hecht, T. 2013. A review of on-farm feed management practices for North African catfish (Clarias gariepinus) in sub-Saharan Africa. In M.R. Hasan and M.B. New, eds. On-farm feeding and feed management in aquaculture. FAO Fisheries and Aquaculture Technical Paper No. 583. Rome, FAO. pp. 463–479. ABSTRACT This review considers feed management practices for North African catfish (Clarias gariepinus) in sub-Saharan Africa. Clariid catfish production in the subcontinent is increasing exponentially, particularly in Uganda. Semi-intensive pond culture is still the most prevalent production system, while intensive tank culture is becoming more popular in peri-urban areas in Nigeria. Total production in these two countries now exceeds 178 000 tonnes annually. Catfish are now commonly spawned and their larvae reared in hatcheries for ten to 14 days, after which they are reared in nursery ponds or in tanks. Extensive rearing of larvae, after yolk sac absorption, in ponds is now less often practiced than in the past. Where it is still practiced, successful larval rearing and satisfactory survival rates depend mainly on adequate fertilization schedules. Feed management practices in hatcheries are closely matched with the physiological and endocrinological ontogeny of the fish. For optimal survival and growth, live food (mainly Artemia) is required for the first five days after the start of exogenous feeding, after which the fish can be weaned onto a dry starter feed. -

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. -

Malawi 5 Animal Science Department, Bunda College, Box 219 Lilongwe Abstract A study to determine preference and acceptability of roasted, fried and boiled Oreochromis spp, (Chambo), Rhamphochromis spp (Ncheni) and Bagrus meridional is (Kampango) from Lake Malawi was conducted in Oc tober 2002, at Bunda College. A sensory panel of 73 people from Bunda College community responded to a structured questionnaire and carried out a sensory evaluation on unidentified fish samples to determine the most preferred fish species. Results from a structured questionnaire showed that Chambo was the most pre ferred species at the market, while the sensory evaluation revealed that most people (65% and 93%) ranked Ncheni as first choice for taste and preference, respectively. Results suggest that while people perceive Chambo as the best fish and hence escalating its demand and therefore its price, Chambo may not be the best in terms of taste.

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. -
