African Shads, with Emphasis on the West African Shad Ethmalosa Fimbriata
American Fisheries Society Symposium 35:27-48, 2003 © 2003 by the American Fisheries Society African Shads, with Emphasis on the West African Shad Ethmalosa fimbriata EMMANUEL CHARLES-DOMINIQUE1 AND JEAN-JACQUES ALBARET Institut de Recherche pour le Deoeioppement, 213 rue Lafayette, 75480, Paris Cedex 10, France Abstract.-Four shad species are found in Africa: twaite shad Alosa fallax and allis shad A. alosa (also known as allice shad), whose populations in North Africa can be regarded as relics; West African shad Ethmalosa [imbriata (also known as bonga), an abundant tropical West African species; and kelee shad Hi/sa kelee, a very widely distributed species present from East Africa to the Western Pacific. Ethmalosa fimbriata has been the most studied species in this area. The concentrations of E. fimbriata are found only in estuarine waters of three types: inland, coastal, and lagoon estuaries. The species is rare in other habitats. Distribution thus appears fragmented, with possible exchanges between adjacent areas. In all populations, juveniles, subadults, and mature adults have different habitat preferences. These groups are distinguished by local people and can be considered as ecophases. The older group has a preference for the marine environment, and the intermediate one is more adapted to estuaries, with a large plasticity within its reproductive features. Information regarding population dynamics is poorly documented, but the populations appear generally resilient except when the estuarine environment deteriorates. West African shad has been exploited for many years and carries great cultural value for the coastal people of West Africa. The catches are marketed cured in the coastal zone, sometimes far from the fishing areas. -

Balanced Adaptive Simulation of Pollutant Transport in Bay of Tangier (Morocco)
ISSN 1 746-7233, England, UK World Journal of Modelling and Simulation Vol. 10 (2014) No. 1, pp. 3-19 Balanced adaptive simulation of pollutant transport in Bay of Tangier (Morocco) Elmiloud Chaabelasri1∗, Alistair George Liam Borthwick2, Najim Salhi1, Imad Elmahi3 1 LME, Faculte´ des Sciences, BP 717, 60000 Oujda, Maroc 2 Department of Engineering Science, University of Oxford, Parks Road, Oxford OX1 3PJ, UK 3 EMCS, ENSAO, Complexe universitaire, B.P. 669, 60000 Oujda, Maroc (Received February 19 2013, Accepted December 17 2013) Abstract. A balanced adaptive scheme is proposed for the numerical solution of the coupled non-linear shal- low water equations and depth-averaged advection-diffusion pollutant transport equation. The scheme uses the Roe approximate Riemann solver with centred discretization for advection terms and the Vazquez scheme for source terms. It is designed to handle non-uniform bed topography on triangular unstructured meshes, while satisfying the conservation property. Dynamic mesh adaptation criteria are based on the local pollutant concentration gradients. The model is validated for steady flow over irregular bed topography, recirculation due to a sidewall expansion in a frictionless channel, and pollution advection in a flat-bottomed channel. An idealised application to the simulation of pollution dispersion in the Bay of Tangier, Morocco is presented, which demonstrates the capability of the dynamically adaptive grid model to represent water quality scenarios in a bay of non-uniform bed topography and complicated shoreline. Keywords: shallow water equations, pollutant transport, finite volume method, roe solver, dynamic mesh adaptation, unstructured meshes 1 Introduction Pollution of the Strait of Gibraltar has increased significantly in recent decades as a by-product of the growth of maritime transportation activities. -

J.E.Afr.Nat.Hist.Soc. Vol.XXV No.3 (112) January 1966 CHECK LIST OF ELOPOID AND CLUPEOID FISHES IN EAST AFRICAN COASTAL WATERS By G.F. LOOSE (East African Marine Fisheries Research Organization, Zanzibar.) Introduction During preliminary biological studies of the economically important fishes of the suborders Elopoidei and Clupeoidei in East African coastal waters, it was found that due to considerable confusion in the existing literature and the taxonomy of many genera, accurate identifi• cations were often difficult. A large collection of elopoid and clupeoid fishes has been made. Specimens have been obtained from purse-seine catches, by trawling in estuaries and shallow bays, by seining, handnetting under lamps at night, and from the catches of indigenous fishermen. A representative fartNaturalof thisHistory),collectionLondon,haswherenow beenI wasdepositedable to examinein the Britishfurther Museummaterial from the Western Indian Ocean during the summer of 1964. Based on these collections this check list has been prepared; a review on the taxonomy, fishery and existing biological knowledge of elopoid and clupeoid species in the East African area is in preparation. Twenty-one species, representing seven families are listed here; four not previously published distributional records are indicated by asterisks. Classification to familial level is based on Whitehead, P.J.P. (1963 a). Keys refer only to species listed and adult fishes. In the synonymy reference is made only to the original description and other subsequent records from the area. Only those localities are listed from which I have examined specimens.

Other Processes Regulating Ecosystem Productivity and Fish Production in the Western Indian Ocean Andrew Bakun, Claude Ray, and Salvador Lluch-Cota
CoaStalUpwellinO' and Other Processes Regulating Ecosystem Productivity and Fish Production in the Western Indian Ocean Andrew Bakun, Claude Ray, and Salvador Lluch-Cota Abstract /1 Theseasonal intensity of wind-induced coastal upwelling in the western Indian Ocean is investigated. The upwelling off Northeast Somalia stands out as the dominant upwelling feature in the region, producing by far the strongest seasonal upwelling pulse that exists as a; regular feature in any ocean on our planet. It is surmised that the productive pelagic fish habitat off Southwest India may owe its particularly favorable attributes to coastal trapped wave propagation originating in a region of very strong wind-driven offshore trans port near the southern extremity of the Indian Subcontinent. Effects of relatively mild austral summer upwelling that occurs in certain coastal ecosystems of the southern hemi sphere may be suppressed by the effects of intense onshore transport impacting these areas during the opposite (SW Monsoon) period. An explanation for the extreme paucity of fish landings, as well as for the unusually high production of oceanic (tuna) fisheries relative to coastal fisheries, is sought in the extremely dissipative nature of the physical systems of the region. In this respect, it appears that the Gulf of Aden and some areas within the Mozambique Channel could act as important retention areas and sources of i "see6stock" for maintenance of the function and dillersitv of the lamer reoional biolooical , !I ecosystems. 103 104 large Marine EcosySlIlms ofthe Indian Ocean - .

A Biographical Study of Bishop Ralph Edward Dodge 1907 – 2008
ABSTRACT Toward a New Church in a New Africa: A Biographical Study of Bishop Ralph Edward Dodge 1907 – 2008 This biography of a Methodist Bishop, Ralph Edward Dodge is an extensive look into how, as a missionary, mission board executive, and bishop, Dodge applied principles of indigenization he embraced as a young man preparing for missionary work to the complexities of ministry in Southern Africa when empires were withdrawing and new nations were forming. Written by an African, the dissertation examines Dodge’s impact upon the several countries in which he was involved as a churchman ‒ countries that would soon move from imperial subjugation to independence. Ralph Edward Dodge (1907–2008) was an American missionary and Bishop of the Methodist Church and United Methodist Church. He was born in Iowa and went to Africa in 1936 at age 29. He began his missionary career in the Portuguese colony of Angola. Except for four years during World War II, he would serve there until 1950. During the war, he continued his postgraduate work, obtaining two more degrees, including a PhD. Afterwards, Dodge and his family returned to Africa. In 1950, he was asked to serve as Executive Secretary for Africa and Europe at the Methodist Church’s Board of Missions in New York. Six years later, the Reverend Doctor Dodge would return to Africa as Bishop Dodge, the first Methodist Bishop elected by the Africa Central Conference, and the only American. His Episcopal Area included the colonial territories of Angola, Mozambique, and Southern Rhodesia (now Zimbabwe). When his twelve-year term was ended, he was elected “Bishop for Life.” Bishop Dodge remained in Africa until his “retirement” in 1968.
