Abstract:
Abstract Following a study of gill pathology in African catfish (Clarias gariepinus) and Nile Tilapia (Oreochromis niloticus) from the Sanyati Basin of Lake Kariba, Zimbabwe, a similar survey was carried out in thirteen other common fishes of Lake Kariba. Gill tissues were dissected from the fish, preserved and prepared for histology. The prepared tissue sections were observed under a light microscope. Six histopathological lesions were observed, namely epithelial lifting, hyperplasia, lamellae fusion, parasitic cysts, oedema, and aneurysm. Epithelial lifting was prevalent in all fish species whilst aneurysm was only observed in two fish species. Synodontis zambezensis had the highest prevalence of gill lesions whilst Marcusenius microlepidotus, Brycinus imberi and Micralestes acutidens had the least prevalence of lesions. Most of these histopathological lesions were mild to moderate, and this is suggestive of good health of the fish species investigated. Seventy seven percent of the fish species were infected with monogenean ectoparasites. More research on fish health in Lake Kariba is recommended and future studies should aim to quantify these histological changes in relation to environmental conditions of the lake. This will enable histopathology to be used as a biomarker or predictor of water quality.

Abstract:
The objective of the study was to determine the quality and consumer preferences of Nile tilapia (Oreochromis niloticus) from two water bodies with different pollution levels and trophic states. Water quality assessment of the two impoundments was carried out. Fish were sampled from hypereutrophic Lake Chivero and oligomesotrophic Lake Kariba for proximate analysis, carcass quality, and sensory evaluation. Conductivity, dissolved oxygen, transparency, ammonia, total phosphates, reactive phosphates, and chlorophyll a were significantly different (P<0.05). Fish from Lake Kariba had significantly higher condition factors and lower fillet yields, while fish of length 10-20 cm, from Lake Chivero had significantly more fat. Lake Chivero fish were darker, greener, and less red while Lake Kariba fish were lighter, less green, and less red. Raw fish from Lake Kariba were significantly firmer, were less green and redder, had a stronger typical fish odour, and were more acceptable than Lake Chivero fish. Lake Chivero fish had a stronger foreign fish odour than their counterparts. No statistical differences were observed on fillet cooking losses, cooked fish sensory parameters, and acceptability. The fish could, however, not be safe due to possibility of toxins in water and feed (algae) which may bioaccumulate and ultimately affect other attributes of fish quality.

Abstract:
This paper deals with conservation issues and threats faced by the inshore fishery of Lake Kariba, where human actions such as poaching and introduction of alien species are threatening the indigenous species. Lake Kariba is a Man-made Lake that was created in 1956–58 and has undergone a number of changes from a eutrophic stage in its early years to the present oligotrophic state. Tied up with this were changes in hydrology, the initial filling phase being marked with high fish-yields, then the booming of the pestiferous Salvinia molesta, until 1971 marked the end of evolutionary changes and the beginning of the decline in nutrient status of the Lake.One of the two fisheries of Lake Kariba is described: the inshore fishery, which is the richer and more interesting in terms of diversity and conservation. This fishery is exploited by artisanal fishermen who use ‘primitive’ means. The fish species involved are vulnerable, as they take a long time to grow and have generally a low fecundity as compared with the ‘sardines’. The famous sport-fish Hydrocynus vittatus (Tigerfish) is, in particular, threatened by human activities.Fishery regulations and management laws are implemented by LKFRI — a Zimbabwe Government institute under the Department of National Parks & Wildlife Management. Whereas the regulations appear sound and reasonable, economic hardships and human population growth in the hinterland have caused changes in the attitudes of people. Fishing is an easy source of revenue, but policing it has become costly and difficult.

Abstract:
AbstractTwo new and one known species of Annulotrema Paperna & Thurston, 1969 are reported from the gills of the tigerfish Hydrocynus vittatus Castelnau, 1861, collected in Lake Kariba, Zimbabwe. The new species, Annulotrema pseudonili n. sp. and A. bracteatum n. sp., are described and distinguished mainly on the basis of features of the male copulatory organ (MCO). Annulotrema pseudonili n. sp. most closely resembles A. nili Paperna, 1973, but differs from it by possessing a more delicate MCO with a thin-walled base without a fibrous distal part. Annulotrema bracteatum n. sp. is most similar to Annulotrema ruahae Paperna, 1973, from which it differs by having an MCO composed of a longer copulatory tube and a leaf-shaped accessory piece enveloping the distal part of the tube. The presence of Annulotrema pikoides Guégan, Lambert & Birgi, 1988 on H. vittatus in Zimbabwe represents a new locality record for this parasite.

Abstract:
Abstract In this paper, monthly, maximum seasonal, and maximum annual hydrometeorological (i.e., evaporation, lake water levels, and rainfall) data series from the Kariba catchment area of the Zambezi River basin, Zimbabwe, have been analyzed in order to determine appropriate probability distribution models of the underlying climatology from which the data were generated. In total, 16 probability distributions were considered and the Kolmogorov–Sminorv (KS), Anderson–Darling (AD), and chi-square (χ2) goodness-of-fit (GoF) tests were used to evaluate the best-fit probability distribution model for each hydrometeorological data series. A ranking metric that uses the test statistic from the three GoF tests was formulated and used to select the most appropriate probability distribution model capable of reproducing the statistics of the hydrometeorological data series. Results showed that, for each hydrometeorological data series, the best-fit probability distribution models were different for the different time scales, corroborating those reported in the literature. The evaporation data series was best fit by the Pearson system, the Lake Kariba water levels series was best fit by the Weibull family of probability distributions, and the rainfall series was best fit by the Weibull and the generalized Pareto probability distributions. This contribution has potential applications in such areas as simulation of precipitation concentration and distribution and water resources management, particularly in the Kariba catchment area and the larger Zambezi River basin, which is characterized by (i) nonuniform distribution of a network of hydrometeorological stations, (ii) significant data gaps in the existing observations, and (iii) apparent inherent impacts caused by climatic extreme events and their corresponding variability.

Abstract:
Taylor’s power law (TPL), which states that the variance of abundance is a power function of mean abundance, has been used to design sampling of agricultural pests and fish species. We show that TPL holds for means and variances of abundance of accumulated fish samples in the fished and unfished areas separately of Lake Kariba (between Zambia and Zimbabwe), measuring abundance indices by number and weight separately. We use TPL parameters estimated from sequentially accumulated samples to update a stopping line of fixed precision 0.1 after each new sample from a sampling day. In these Lake Kariba data, depending on the sampling area and abundance measure, our updated stopping-line method requires 21% to 41% of the number of sampling days and 19% to 40% of the number of samples that are planned a priori and performed under systematic sampling. Our novel method yields mean abundance estimates similar to those from systematic sampling and provides a conservative approach to reaching a fixed sampling precision level with reduced sampling labor and time. Using mixed-effect modeling for cumulative means and variances with either number or weight from both fished and unfished areas, we find that fishing increases the slope of TPL. This study provides the conceptual framework and an empirical case study for implementing a sequential sampling method for fish assemblages of an inland lake. The possible limitations and applications of our method for sampling in other environments are discussed.

Abstract:
Small-scale fisheries play a significant role as a source of employment, livelihood strategy and contributor to food security. However, changes in climatic variables alter the productivity and distribution of marine and freshwater fish species, negatively affecting the livelihoods of fishery-dependent communities. This study seeks to identify small-scale fishers’ livelihoods and examine the impacts of climate change on livelihoods and food security of small-scale fishing households. The study was conducted in Sanyathi fishing basin in Lake Kariba, Zimbabwe. The Sustainable Livelihood Approach framework of the Department for International Development was used to define the small-scale fishers’ livelihood assets and activities. The study employed a mixed-method approach for data collection. A pretested, semi-structured questionnaire, focus group discussions and observations were used to collect data from the small-scale fishers. The data collected were subjected to descriptive and bivariate analysis. The present results indicate that fishing is the community’s primary livelihood activity. More than 62% of fishermen stated that fishing revenue is declining, owing to declining fish catches. Of participants, 98% recognised food purchases as the primary source of food. Therefore, 78% of the small-scale fishers perceive their households to be food insecure due to declining incomes from fisheries. These findings show the need for policymakers and development agencies to formulate strategies that specifically target fishing communities whose livelihoods rely on natural ecosystems.

Abstract:
Zimbabwe Peoples’ Revolutionary Army (ZIPRA) was the armed wing of Zimbabwe African People’s Union (ZAPU) which waged the war to liberate Zimbabwe. It operated from its bases in Zambia between 1964 and 1980. Umkhonto Wesizwe (MK) was ANC’s armed wing which sought to liberate South Africa from minority rule. Both forces (MK and ZIPRA) worked side by side until the attainment of independence by Zimbabwe when ANC guerrillas were sent back to Zambia by the new Zimbabwean government. This paper argues that the failure of ZIPRA and Umkhonto Wesizwe to deploy larger numbers of guerrillas to the war front in Zimbabwe (then Rhodesia) and South Africa was mainly caused by bio-physical challenges. ZAPU and ANC guerrillas faced the difficult task of crossing the Zambezi River and then walking through the sparsely vegetated areas, game reserves and parks until they reached villages deep in the country. Rhodesian and South African Defense Forces found it relatively easy to disrupt guerrilla movements along these routes. Even after entering into Rhodesia, ANC guerrillas had environmental challenges in crossing to South Africa. As such, they could not effectively launch protracted rural guerrilla warfare. Studies on ZIPRA and ANC guerrilla warfare have tended to ignore these environmental problems across inhospitable territories. For the ANC, surveillance along Limpopo River and in Kruger National Park acted more as impediments than conduits. ANC also had to cope with almost all challenges which confronted ZIPRA guerrillas such as the Zambezi, Lake Kariba and various parks which Rhodesians always used as a first line of defense but had a geographically difficult task in South Africa where the environment was not attractive for a guerrilla warfare.
