The Vertical Distribution

Each fish species tends to choose a suitable environment suitable for its survival and reproduction horizontally and vertically. Blue shark (Prionace glauca) is the dominant catch of pelagic sharks by-catch in the Eastern Indian Ocean longline tuna fishery, with about 70% of the total sharks caught in this fisheries. This study aims to provide the information and the vertical analysis distribution of blue sharks based on temperature and depth in the Indian Ocean. The scientific observer collected 2,951 set-by-set longline fishing data based on Research Institute For Tuna Fisheries (RITF) from January 2006 to December 2018, on which the present analysis was made. The mini logger was used to measure the vertical distribution of blue sharks in the longline fisheries. This result indicated that blue shark was caught between 75.18-445.46 m depth, with 84% of which live at thermocline area (70-300 m depth), and 16% lived in underlayer area (>300 m depth). Blue sharks distributed in the underlayer area have a larger body size than those in the thermocline area with a size >180 cmFL compared to 50-170 cmFL in the thermocline area.

Literacy Identity

This paper surveys the history of dictionary construction and orthographic choice in the Comoros — a former French colony in the Indian Ocean — with special reference to issues of literacy, identity, and politics. Evidence ranging from 16th century wordlists to contemporary bilingual/bidirectional dictionaries, as well as colonial, missionary, and scholarly approaches to lexicography and orthography in the Comoros, are examined and compared. While Arabic-influenced writing systems have a long history in the Comoros, the experiences of colonialism and independence in the 20th century introduced French- and phonemically-influenced systems. As the Comoros move into the 21st century, linguists and ethnographers are attempting to assist with questions of standardization, literacy, and dictionary construction. The situation remains fluid, with considerations of tradition, modernity, nationalism, and representation to be taken into account. This paper seeks to address the complex interrelationships between orthographic choice and ethnic identity in the Comoros, with special reference to the development of the first bilingual/bidirectional Shinzwani-English dictionary.

AbstractThe paper first situates the trade carried on by private European traders in the overall framework of the Indian Ocean trade in the early-modern period. It then discusses in some detail the trading network of private English merchants in the Western Indian Ocean with special reference to the Surat-Mocha link in the 1720s and the 1730s. The evidence base is provided mainly by the private papers of Sir Robert Cowan, governor of Bombay between 1729 and 1734 and a major English private trader, operating in collaboration with Henry Lowther, chief of the English factory at Surat. Cette contribution replace tout d'abord les activités commerciales menées par les négociants européens dans le cadre général du commerce de l'Océan indien au cours de la période moderne. Elle examine ensuite avec quelque détail le réseau commercial établi par des négociants anglais privés dans le secteur occidentalde l'Océan indien, plus particulièrement les relations instituées entre Surat et Moka dans les années 1720-1730. Les données présentées ont été tirées principalement de la correspondance privée de Sir Robert Cowan, gouverneur de Bombay (1729-1734) et grand négociant privé, associé à Henry Lowther, responsable du comptoir de Surat.

The Subject

The discovery of new areas beyond the Atlantic Ocean and the pioneering of a new searoute via the Cape to the Indian Ocean led to expansion of western Europe in the sixteenth century. There of course followed the development of trade routes to the new areas outside Europe, but there was also a significant expansion of trade inside Europe and the Middle East, as well as changes in existing trade and production patterns. These are the subject of this paper.
