Indigenous knowledge use in identifying artisanal fishing zones is the core issue in this dissertation. It seeks, on one hand, to show the potentially of this knowledge and to establish the relationships between indigenous and scientific knowledge in fishing zones identification and, on other the hand, it is also a trend for alleviating those fishing zones surrounding beaches, estuaries and bays highly exploited by artisanal fishermen. Pushing artisanal fishermen upward offshore and/or into the open sea, they will fish more quality and high economic value fish contributing to enhance their income. By so doing, artisanal fishermen will uplift their living standard and, at the same time, they will contribute to sustainable artisanal fisheries management. Angoche District in Nampula province, north of Mozambique is the study area. The study was carried out to describe the logical sequence underlying on the process of identifying artisanal fishing zones using indigenous knowledge. The relationship between indigenous and scientific knowledge is treated with particular attention. The nature of the study is descriptive and analytical based on qualitative and quantitative data. The method used for data collection was face-to-face interviews using structured and semi-structured open-ended questions. Data on socioeconomic, traditional and cultural practices, technological and climate characteristics were collected, analyzed and discussed. Factors underlying artisanal fishing zones were studied. Spatial and non-spatial information for artisanal fishing zones identification was recorded applying Global Positioning Systems (GPS) and, later, processed and analyzed employing Geographical Information Systems (GIS). Finally, a map showing the localization and distribution of the identified fishing zones in the study area was produced. Results from the research show that identification of fishing zones offshore or open sea can be done simply based on local indigenous knowledge. The GIS technology employment facilitates the inclusion of indigenous knowledge into other knowledge which can be used for local decision making. Sustainable fisheries management can only be achieved by developing a science based on the priorities of local people, and creating a technological base that includes both traditional and modern approaches to problem-solving. / Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2007.

Magister Philosophiae - MPhil (LAS) (Land and Agrarian Studies) / Fish remains a vital source of food, income, nutrition and livelihoods for millions of people in Africa. This study investigated the modalities of trading in fish imported from sub-Saharan Africa into South Africa in the Cape Town Metropolitan area. The research analyses the opportunities and constraints faced by retail fish traders and importers regarding the South African and Southern African Development Community (SADC) policies that are in place, to ascertain how far the policies go in facilitating the intra-regional fish trade. In addition, the study analyses consumer factors underlying the attractiveness of imported fish, the channels used for importation as well as the types and forms of fish imported into South Africa. The study employs a qualitative approach using semi-structured interviews with purposively selected key informant retailers, traders and City of Cape Town officials to collect the information. Findings show that shop owners and traders face challenges in relation to obtaining the required documents for trading, sanitary and phytosanitary certification and tariff and non-tariff barriers at borders. Some of these challenges include long and tedious procedures to acquire documents, as well as the limitations placed on the amount of goods traders can import. Consumers (mostly from the diaspora) prefer the taste of fish that they are used to, thereby creating an increasing demand for imported fish. National and regional policies put in place do not facilitate the trade in fish as well as current municipal regulations for retailing imported fish and other food types. The study also raises critical questions about the implementation of sanitary and phytosanitary standards by officials in the food shops. The thesis concludes that is it critical for national and regional policies to be coordinated and harmonised for enhanced intra-regional fish trade, which could contribute towards increased food security, nutrition and livelihoods.

The South African mariculture industry is developing the rearing technology of indigenous fish species. Dusky kob (Argyrosomus japonicus) has high-quality flesh and a good market demand. Research is needed to determine the environmental requirements under which growth of dusky kob is optimised. This study assessed the effect of temperature, light intensity, feeding frequency and stocking density, respectively, on growth, feed conversion ratio (FCR) and survival of juvenile dusky kob within a weight range of 10-60 g fish⁻¹) in a series of four growth trials. The effect of temperature on growth and FCR was assessed at 14 temperatures from 17 to 28°C. The temperature for best growth was estimated to be 25.3 °C, while 21.4 °C was the temperature at which the best FCR was achieved. A growth trial testing the effect of light intensity on growth showed that light intensity did not affect growth in the range of 23 – 315 lx. Fish fed a restricted ration of 3.6% body weight per day (chapter 2) or 3.41% body weight per day (chapter 4) had a better FCR than fish fed to satiation. A trial to assess the effect of feeding frequency on growth and FCR showed that fish fed both two or three times daily grew better than those fed once daily. FCR was best in fish that were fed once or twice daily. Preliminary analysis of the results from a stocking density trial showed that stocking density in the range of 10 – 50 kg m⁻³ did not affect growth of juvenile dusky kob. It is recommended to culture dusky kob at a temperature of 25.3 - 21.4 °C at stocking densities up 50 kg m⁻³ to maximise growth. However, a study is needed to determine the environmental conditions needed to maximise profit under commercial conditions. The results allow the South African industry the opportunity to assess the culture potential of this species. In addition, the results will help develop protocols that can be used in other South African candidate aquaculture species such as silver kob, yellowtail, white-stumpnose and sole.

The main objective of this thesis is to provide an analysis of the economic logic behind fisheries policy and redistribution in South African. An examination of the institutional and organizational evolution reveals that South African fisheries policy followed the world trend in the movement toward quota management systems. However, it is argued that due to the peculiarities of the Apartheid political system, South Africa developed a unique and persistent structure of individual fishing rights that resulted in a transfer of power from the fisher to monopsonistic, and subsequently vertically integrated, fish processing companies. Problems, however, arose with the need to redistribute fishing rights to previously repressed racial groups. It is proposed that, within a specific form (TAC), the structure of individual fishing rights can be decomposed into four operational rules, namely, the right of participation, asset size, tradability and duration of term. Policy design is restricted to a feasible set of rules that impact on the flexibility of the system, the incentives facing private fishing companies and fishers, the efficiency of the fisheries management plan and finally the effect it has on a redistribution strategy. Within this analytical framework, South Africa's policy yields a very flexible system favourable to monopsonistic industrial organisation. However, by adding a redistribution constraint, this structure has a number of important effects. First, as new quota holders are added the information costs for effective fisheries management increase exponentially. Second, the transaction costs to private fishing companies are increased. Third, only the resource rent is redistributed (weak redistribution). Next, the micro to small vessel fisheries, the medium vessel fisheries and the large vessel fisheries are examined separately. The major aim is to determine, within the available data, the effect that a weak redistribution policy (redistribution of the resource rent), has on strong redistribution (redistribution of fishing capital and skills). The evidence definitely supports the analytical framework and suggests that fundamentally the structure of individual fishing rights, which evolved in response to a monopsonistic industrial organisation during the apartheid era in South Africa, works against strong redistribution. Also, that different fisheries face different constraints and that these should in certain instances be treated separately.

The developemnt of fisheries in Lake Victoria is faced with a myriad challenges including overfishing, environmental destruction, disappearance of certain indigenous species and pollution. All these problems can be located within the social, economic and political systems that exists today and in the past. This thesis, ‘Fishers and Fish Traders of Lake Victoria : Colonial Policy and the Development of Fish Production in Kenya, 1880-1978’, argues that the Luo fishers had their own indigenous techniques of fishing, modes of preservation and systems of management that ensured sustainable utilisation of fisheries. The thesis examines the role of the Luo fishers in the sustainable usage of the Lake Victoria fisheries. The British colonial settlers came up with new policies of plantation and commercial farming, taxation and forced labour, all of which encouraged the Luo fishers to partially break with their pre-colonial systems and create new ways of responding to the demands of the colonial state. The study argues that the coming of colonialism and its attendant capitalism introduced new fishing gear as well as new species, such as mbuta, that were inimical to the sustainable utilisation of the Lake Victoria fisheries. The colonial regime also introduced new practices of fisheries management such as scouts, licensing, closed seasons and the numbering of boats, practices geared towards ensuring the commercial production and development of the fisheries. This commercialisation led to cut-throat competition between Asian, European and African fish traders. The coming of independence in 1963 brought some changes, such as the provision of credit facilities, new technology, and attempts by the new African government to more effectively control and manage the fisheries. However, not much changed in terms of policy objectives, and most of the colonial policies remained unchanged. New industries were established around the fisheries, but most remained in the hands of Asians and a few African middlemen. The small-scale fishers continued to struggle against the commercialisation of fishery production, remaining voiceless and marginalised. The study recommends an all inclusive participatory approach to solve the problems currently affecting the Lake Victoria fisheries. / History / DLITT (History)

Sound management of information and data is an essential cornerstone for efficient and effective decision making. Structured, up to date and easily retrievable data from several heterogeneous sources is often required to effectively manage, monitor and predict resource quantities particularly for depleting resources such as fish. The documentation and management of fisheries data in most developing countries however poses great challenges. The main aim of this study therefore is to design an information system (IS) for Artisanal Fisheries management. The developed IS is supported by a database. Secondary data, from the provincial offices of Moma and Angoche in Mozambique, is used to test and populate the prototype database. The manner in which the database is developed demonstrates how in practice a database can be created as part of an information system. However, due to time restrictions, a complete database for the AF system could not be developed. To accomplish the objectives of the study, a model of the Artisanal Fisheries (AF) system was developed first. Based on standard system development approaches, the key components of the AF system that include; processes, data flows and data stores, were identified. The developed conceptual system was then used to identify critical data stores for the AF system and data models were subsequently developed. A prototype database to support the AF system was then implemented in MS Access. The motivation for this study is as a result of two observations made on information management which are a challenge in artisanal fisheries management in Moma-Angoche. These observations are; (i) the current information system lacks a structured approach and a database to document and archive data/information on the artisanal fisheries subsector; and, (ii) the high proportion of the data/information collected from different sources is not well processed, analyzed and is not user-friendly as yet. The Moma-Angoche Provincial Fisheries office was chosen because it is strategically suitable for research. This has been demonstrated by the amount of socio-economic artisanal fishing census data already collected and by the research on stock marine resources already carried out. As a result, the study area has become a pilot zone of integrated fisheries development projects. During the life cycle of the various projects, and even after their termination, the area remained an important zone where subsequent studies (for example baseline studies) were carried out. Furthermore, the existence of subsequent data available from those studies allows a good opportunity for data comparisons to be made. / Thesis (M.Env.Dev.) - University of KwaZulu-Natal, Pietermaritzburg, 2007.
