Phytoplankton Composition at Jeddah Coast–Red Sea, Saudi Arabia in Relation to Some Ecological Factors
JKAU: Sci., Vol. 22 No. 1, pp: 115-131 (2010 A.D. / 1431 A.H.); DOI: 10.4197 / Sci. 22-1.9 Phytoplankton Composition at Jeddah Coast–Red Sea, Saudi Arabia in Relation to some Ecological Factors Hussein E.

Abstract. Phytoplankton succession in relation to some physico- chemical characters of some water bodies at Jeddah Coast (Saudi Arabia) was studied for one year (2004). The sampling program included four different areas, North Obhour, Technology area, Down Town area and South Jeddah Area. Water samples were analyzed for some physico-chemical parameters (Temperature, pH, S‰, Dissolved +2 +2 Oxygen (DO), Calcium (Ca ) & Magnesium (Mg ), Nitrite (NO2), Nitrate (NO3), Ammonia (NH3), Reactive Orthophosphate (PO4) and Reactive Silicate (SiO3) as well as phycological parameters (Phytoplankton communities and Chlorophyll a). The Jeddah Coast was found to be oligotrophic ecosystem in some areas, while some of these areas were mesotrophic with high phytoplankton density such as the Down Town and South Jeddah areas. The results showed that, the high phytoplankton density attaining the maximum of 2623.2 X 103/m3 at Down Town area during spring and the minimum of 118.7 X 103/m3 at Technology area during winter. Seventy three species belonging to 73 genera and 5 groups were recorded. Dinophyceae was the first dominant group forming 43.8% of the total phytoplankton communities followed by Bacillariophyceae 27.9%. -
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. -

Geological Evolution of the Red Sea: Historical Background, Review, and Synthesis William Bosworth Abstract The Red Sea is part of an extensive rift system that includes from south to north the oceanic Sheba Ridge, the Gulf of Aden, the Afar region, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Cairo basalt province. Historical interest in this area has stemmed from many causes with diverse objectives, but it is best known as a potential model for how continental lithosphere first ruptures and then evolves to oceanic spreading, a key segment of the Wilson cycle and plate tectonics. -

It has been accepted for inclusion in Louisiana Law Review by an authorized editor of LSU Law Digital Commons. For more information, please contact [email protected]. OIL RIGHTS IN THE GULF OF SUEZ International law recognizes that coastal nations have the right to exploit natural resources found in continental shelf areas beneath adja- cent water bodies. In most situations the coastal nation entitled to this right is easily identified as the sovereign in actual control of the land immediately adjacent to the water body. However, the nation in physi- cal control of such land may not be the sovereign thereof. In such a case, both the nation having actual control and the nation claiming sov- ereignty may assert the right to exploit natural resources in the adjacent continental shelf. Such a situation currently exists in the Gulf of Suez. When Israel invaded the Sinai in 1967 it acquired the possession but not the sovereignty of that territory. Now, both Egypt, as sovereign, and Israel, as occupant, claim the right to drill for oil in the adjacent conti- nental shelf. The Gulf of Suez is a semi-enclosed body of water which opens into the Red Sea at the south and narrows into the Suez Canal at the north. -

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 - .

Little Fish, Big Impact: Managing a Crucial Link in Ocean Food Webs
little fish BIG IMPACT Managing a crucial link in ocean food webs A report from the Lenfest Forage Fish Task Force The Lenfest Ocean Program invests in scientific research on the environmental, economic, and social impacts of fishing, fisheries management, and aquaculture. Supported research projects result in peer-reviewed publications in leading scientific journals. The Program works with the scientists to ensure that research results are delivered effectively to decision makers and the public, who can take action based on the findings. The program was established in 2004 by the Lenfest Foundation and is managed by the Pew Charitable Trusts (www.lenfestocean.org, Twitter handle: @LenfestOcean). The Institute for Ocean Conservation Science (IOCS) is part of the Stony Brook University School of Marine and Atmospheric Sciences. It is dedicated to advancing ocean conservation through science. IOCS conducts world-class scientific research that increases knowledge about critical threats to oceans and their inhabitants, provides the foundation for smarter ocean policy, and establishes new frameworks for improved ocean conservation.
