Tunas are the ocean highly migratory species, Taiwan is the top countries of the tropical tunas fishery in the Indian Ocean, and the tropical tunas are the main target species of our country in Indian Ocean. There were no systematic arrangement of large-scale tuna longline fishery in the past. While assessing the resource assessment, there are only few information included and discussed .The Purpose of this research based on the large-scale fishing vessels¡¦ logbooks, and analyzed the catch, CPUE and fishing effort of tropical tuna longline vessels with geographical information system. Discuss the dynamic patterns of tropical tuna vessels, and try to research the factors influencing the vessels activities. The research focus on the whole Indian Ocean, and utilizes the geographical information system to analyze and research CPUE from 1970 to 2007(38 years) with annual tropical tuna catch. Then, select the steady times of the fishery activities from 1999 to 2003 and carry on the analysis of catch data. Second, choose the first 20 fishing vessels of annual Yellow-fin tunas and Big-eye tunas with largest catch in this period, regard these as the representative researching vessels. According to the navigation route of each vessel, the results of the analysis are derived: 4 patterns of Yellow-fin tuna, 3 patterns of Big-eye tuna. On the whole, there are 5 routes of Taiwan fishing boat of tuna longline fishing vessels in the Indian Ocean: 1. The fishing vessels go back to the equator across Arabian Sea from the equator. 2. The fishing vessels go back to the equator across southern Indian Ocean from Arabian Sea. 3. The fishing vessels go back to the equator across the Bay of Bengal from the equator. 4. The fishing vessels go back to the equator across the southern Indian Ocean from the equator and stay near the equator during the whole year. Finally, conclude that tuna longline fishery of Taiwan target tropical tunas in the Indian Ocean are dominated by factors such as international fish price, climate, walrus and the relationship with fishery cooperative countries, etc.. These factors lead to the 5 kinds of vessel dynamic ways in the Indian Ocean.

My dissertation traces how the interplay of trafficking and regulation shaped free trade in the Arabian Sea. It explores trafficking in the littoral region stretching from western India to the Swahili Coast, as it evolved under colonial regulation. British officials wanted commercial practices in the Arabian Sea to conform to their perception of free trade, but their dedication to laissez-faire policies prevented them from intervening directly in trade. But smuggling provided the perfect justification for intervention. Colonial regulation focused on four illicit arenas that structured free trade: labor, security, finance and transportation. The suppression of the slave trade would produce wage labor. The suppression of the arms traffic would eliminate violence from trade. The regulation of currency arbitrage would create a stable monetary standard. Finally, the regulation of shipping would develop a transportation system which could incorporate distance into the calculation of price. Yet these regulatory efforts were frustrated by merchant networks which exploited the gaps in the enforcement of these regulations. Merchants co-opted regulators, circumvented regulations and evaded policing in order to structure transactions to their own advantage. Thus my dissertation demonstrates how free trade in the Arabian Sea was framed through this intricate interplay of trafficking and regulation. / History

Coastal communities along the east African coastline rely on coral reefs and their associated resources for food security and income. However, increases in the frequency and severity of episodes of coral bleaching have resulted in mass coral moralities in many locations around the world including the western Indian Ocean (WIO). Reef corals obligately host dinoflagellate algal symbionts of the genus Symbiodinium. Coral bleaching is caused by the loss of these symbionts from the host, resulting from a variety of stresses, the major ones being increased seawater temperature and irradiance. The Symbiodinum genus is diverse and the distribution of symbionts is influenced by the host biology, external light environment and geographic location. Ten distinct clades of Symbiodinium have been identified. Although the Caribbean and Great Barrier Reef have been studied intensively with respect to Symbiodinium diversity in many locations in the WIO Symbiodinium diversity is unknown. The aim of this study was to determine diversity, distribution and prevalence of Symbiodinium types in corals along the east African coastline. The Symbiodinium ssrDNA region was analysed using restriction fragment length polymorphism (RFLP) in order to assess the cladal diversity of Symbiodinium. The results showed all samples analysed to belong to clade C. To gain more insight into Symbiodinium genetic diversity, the ITS region was employed to assess Symbiodinium diversity at the subcladal level. Twenty ITS types were identified. The most prevalent type was found to be subclade C1. No phylogeographic structuring was found amongst the symbiont types, however, specificity of symbiont types to coral hosts was demonstrated indicating potential susceptibility to perturbations such as increased seawater temperature. / Thesis (M.Sc.)-University of KwaZulu-Natal, Durban, 2007.

The aim of this review is to gave a detailed overview of the status of aquaculture in the Western Indian Ocean Region. Emphasis is based on the legislation, cultured species and candidate species for aquaculture. The review also describes the most recommended species for aquaculture in the region in terms of biology, environmental constraints and factors that inhibit a successful growth. This review covers the Western Indian Ocean (WIO) countries: South Africa, Mozambique, Tanzania, Kenya. Madagascar, Mauritius and Seychelles. Different sources of information are used such as annual reports of each country from Food and Agriculture Organisation (FAO). governmental reports, counties profiles available m the internet. Extensive and semi-intensive aquaculture systems are the most practiced in the WIO countries. Little information is available regarding the environmental impacts associated with aquaculture. The region presents a good potential for developing mariculture. although manculture activities are not yet developed and cannot satisfy the local and international demand for aquatic products. South Africa presents a noticeable development in rearing abalone Haliori: midae while Madagascar and Mozambique the marine shnmp Penaeus monodon. P monodon is the main species reared in the WIO region. Marine species are the most recommended for the region, as opposed to freshwater species, due to the vast coastline. Generally, improvements in the current legislation relating to aquaculture are needed in most of the WIO countries. Mozambique and Madagascar present significant progress in the development of legal framework relating to aquaculture; however, similar efforts have been seen in all countries evaluated. The results of the SWOT (Strengths, Weakness. Opportunities, and Threats) analyses show that the major strength presented by the region is the availability of suitable areas for the aquaculture development. The main strengths regarding aquaculture are the availability of good water quality and Government commitment in developing the sector. The WIO region presents good opportunity to improve the coordination between institutions, avoiding duplications m the process of application for permits. The weaknesses are related mostly to the lack of aquaculture development plans and. although many countries have come as far as drafting such plans, the implementation thereof is still low. The review provides an overview of the current status of aquaculture in the WIO region as well as provides re commendations for best aquaculture pracnces and species that are economically and ecologically suitable. Recommendations are made based on the SWOT analyses for the individual WTO countries from well established aquaculture practicing countries. / Thesis (M.Sc.)-University of KwaZulu-Natal, Westville, 2011.

The present work is mainly concerned with the commercial relations between the Arab world and India in the 3rd and 4th / 9th and 10th centuries. The thesis consists of an Introduction and five chapters. The introduction contains a brief survey of the historical background to the Arab-Indian trade links In the period prior to the period of the research. lt also includes the reasons for choosing the subject, and the difficulties with which the research was faced. The introduction also contains the methods of the research and a study of the main sources. Chapter One deals with the Arab provinces, the main kingdoms of India, the political situation in the Arab world and India, and its effects on the subject. It also deals with the main economic products in the countries concerned. Moreover, the chapter focuses on the factors which encouraged the Arab-Indian trade. Chapter Two deals with the trade routes (Land and Sea routes), the caravans, ships, the sea ports and the commercial cities in the Arab world and India. Chapter Three deals with the trade procedures between the Arab world and India. It also deals with the taxes levied in ports and some land posts. The chapter ends by giving some details of the prices of of goods in both countries. Chapter Four gives a detailed account of goods exported and imported by both sides, and the real causes behind the export and import of these goods. The chapter also gives an account of how sometimes goods are imported by one side from the other in order to meet the local demands or to be exported in a process of trading nn a world wide scale. Chapter Five deals with a conclusion of what has been discussed earlier, in addition to some cultural aspects which have not been dealt with in the chapters above.

The popular tourist destination island of Koh Phi Phi Don, Thailand was heavily affected by the Indian Ocean Tsunami in December 2004, which resulted in a destroyed tourism infrastructure and complete downturn of tourism. Extensive recovery and rebuilding work by emerging community groups, returned locals, international volunteers and Thai government units provided an efficient but hasty reconstruction of the destination. Ethnographic research conducted in the community provided insights into the complex stakeholder interactions and their roles and influences on the reconstruction of the community. The community�s level of vulnerability on Koh Phi Phi Don was influenced by social processes and interactions during the destination�s recovery process as the various stakeholders (e.g. government vs. locals) had differing perceptions of the island�s economic, environmental and social vulnerability. These disputes are grounded in different social time processes, particularly illustrated through land law disputes among locals, landowners and the government. Other factors which influenced the reconstruction of Koh Phi Phi as a tourist destination were pre-tsunami conditions (past overdevelopment), the empowerment of the community, the reconstructed place identity, various anniversary celebrations and the early warning system. A model is suggested to illustrate and discuss Koh Phi Phi Don as a disaster destination, which provides insights into the dynamics which govern a destination�s post-disaster recovery period. Thus, it illustrates how stakeholder interaction is influenced by distinct understandings of the multiple notions of vulnerability. Furthermore, this study establishes essential links between disaster and tourism theories and suggests an extended tourism disaster management framework, which calls for an inclusion of post-recovery processes.
