abstract = {Records of Indo-Pacific humpback dolphin sightings, strandings, and museum specimens in the Arabian region were compiled and used to review the distribution and status of this species. Nominal usage of Sousa chinensis (Osbeck, 1765) has been retained as a pragmatic measure, although the species present in the region resembles Sousa plumbea (G. Cuvier, 1828). Little is known about the ecology of this species in the region. Most available information on S. chinensis in the region originates from the Sultanate of Oman, where this species is among the most commonly recorded cetaceans. However, there is no absolute measure of abundance for anywhere in the region and the status of the species is unknown. Distribution is described for the region to include much of the Arabian (Persian) Gulf, Arabian Sea, Gulf of Aden, and Red Sea, but notably excludes the Gulf of Oman. This discontinuous distribution suggests the possible presence of discrete populations within the region. Beach-cast/dead individuals represent nearly two-thirds of all records (n=303) of this species in Oman. Live sightings indicate unusually large group sizes (up to 100 individuals) in the Arabian Sea and Arabian Gulf. Occasional associations with Tursiops sp. and Delphinus capensis tropicalis were documented. Mating behaviour and the presence of calves were recorded in the months of April and May and calves are also reported in June, October, November and December. Threats to humpback dolphins in the Arabian region include incidental capture in fishing nets, coastal and offshore development (e.g. land reclamation, dredging, port and harbour construction), pollution, boat traffic, oil and gas exploration (including seismic surveying), military exercises and biotoxins associated with red tide events. Evidence for historic and current directed catches of S. chinensis is limited, but opportunistic hunting may occur. Intraspecific variation in cranial measurements of individuals from the Arabian Sea coast of Oman fall within relative values found in individuals from the Saudi Arabian Gulf coast. Cranial abnormalities were few. Recommendations are made for conservation management-oriented research focusing on stock identity and status assessments, as well as for monitoring of fisheries bycatch, clearer definition of other threats, continued specimen and sample collection and training of local scientists.},

abstract = {Significant natural and aquaculture fish deaths in Kuwait Bay occurred from September to October of 1999 and were attributed to a bloom of the dinoflagellate Gymnodinium sp. A chronology of the bloom event suggests that a period of low winds and stable water-column structure preceded the bloom. Maximum cell concentrations of Gymnodinium sp. (>6 x 10(6) cells 1(-1)) were also immediately preceded by more than 20-fold increase in mean inorganic nitrogen concentrations (up to 60 muM) and elevated inorganic phosphate concentrations. This, combined with elevated inorganic and organic nutrient concentrations within the bloom, suggests that coastal nutrient eutrophication was Likely to have contributed significantly to bloom development and support. Termination of the Gymnodinium sp. bloom coincided with abloom of the non-toxic ciliate Mesodinium rubrum, which appeared as large red patches in Kuwait Bay. While no adverse human health effects were associated with the bloom, closure of shellfish and selected finfish (largely mullet Liza macrolepis) markets resulted in significant economic losses to the region. The occurrence of this toxic algal bloom event, the first within the Arabian Sea, highlights the need for monitoring and research programs in the Arabian Sea and Kuwait Bay that focus on nutrients and eutrophication, in addition to oil related pollution issues.},

These human activities coupled with natural disasters have led to reductions in the natural reef systems and marine resources world-wide. Artificial reefs are being deployed in a hope to rehabilitate declining reef systems and enhance fisheries, among other things. In order to assess how successful these structures are in fulfilling their objectives monitoring needs to be carried out. This paper will provide suitable guidelines for a monitoring program to be used on artificial reefs.},

abstract = {The Gulf of Aden lies between southern Arabia and the Horn of Africa and connects with the Red Sea and Indian Ocean. The Socotra Archipelago lies at its entrance, off the Horn of Africa. The largest influence comes from the reversing monsoon system with strong and persistent winds that blow from the southwest in summer, and from the northeast in winter. These also cause a reversal in the direction of surface currents. Associated with the summer monsoon are upwelling areas along the eastern coast of Yemen, and one centred on the Somali coast southwest of Socotra. Both have a profound effect on coastal habitats and stimulate high marine productivity which supports a rich fishery. Marine biodiversity is relatively high since the area is a transition zone between the Red Sea, Southern Arabia and East Africa. Terrestrial diversity, particularly in the flora of Socotra, is also elevated by high levels of endemism. Coasts are mainly exposed sandy beaches separated by rocky headlands. Coral communities and reefs have developed most notably in Djibouti and offshore islands of Somalia. Seagrasses are relatively uncommon, and mangrove stands are most abundant to the west and southwest. A striking feature of rocky shores is the abundant macroalgae that appears following the onset of the Southwest Monsoon in particular. Green turtles nest in tens of thousands, and thousands of dolphins have also recently been observed. Perhaps the most serious single threat to sustainable use of marine resources comes from overfishing, particularly by industrial fleets that operate with or without licenses. Some stocks have collapsed or are showing signs of strain, including cuttlefish, shark and lobster. Wildlife species are also harvested and incidental mortality appears high. Levels of pollution are low except around larger towns where sewage and solid wastes are starting to affect resources. Chronic oil pollution originating from tankers is also cause for concern, but levels appear to be low. Harsh environmental conditions and lack of infrastructure limits exploitation of coastal resources and traditional methods of limiting exploitation are still effective. Political instability and unrest, and lack of funding have hampered coastal management, though a strategic action plan for the conservation and protection of the marine environment has recently been prepared by PERSGA as a crucial first step. There are only two small marine parks in the region, both in Djibouti.},

abstract = {The demersal fisheries of the Arabian Sea, the Gulf of Oman and the Arabian Gulf are reviewed. The region comprises eight countries: Oman, United Arab Emirates (U.A.E.), Qatar, Saudi Arabia, Bahrain, Kuwait, Iraq and Iran. Over 350 commercial fish species, eight shrimp species, two spiny lobster species, one shovel nose lobster species, one cuttlefish species, one crab species, and one abalone species support the demersal fisheries in the continental shelves of the three regions. Artisanal and industrial vessels with over 120 000 fishermen were involved in demersal fisheries. Fishing boats include fish and shrimp trawlers (wooden and steel hulled), large wooden boats (dhow) with inboard engines, small dhows with outboard engines, and fiberglass boats. Fishing gear consists of trawls, bottom gill nets, traps (wire mesh and plastic types), barrier traps, hand lines, and bare hands and knives (to dislodge abalone). Demersal fish (primarily Lethrinidae, Sparidae, Serranidae, Siganidae, Sciaenidae, Stromateidae, Lutjanidae, Trichiuridae, and Nemipteridae) and shrimp (primarily Penaeus semisulcatus, Metapenaeus affinis, Parapenaeopsis stylifera, and Penaeus merguiensis) were the two commercial demersal resources. Approximately 198 000-214 000 tonnes (t) of demersals were landed annually during 1988-1993, accounting for nearly 40% of the total marine landings (475000-552000 t). This percentage, however varied among countries: 25% in Oman, 32% in U.A.E., 71% in Qatar, 52% in Saudi Arabia, 56% in Bahrain, 55% in Kuwait, close to 100% in Iraq, and 41% in Iran. Fishing effort on certain stocks may have been below the optimum level (e.g. certain Omani demersal fish), near the optimum level (e.g. Omani shrimp), or above the optimum level ( e.g. Arabian Gulf shrimp and demersal fish). Overexploitation led to restriction of fishing effort by limiting fishing licenses, regulating fishing gear (mesh size) and capture size, closing fishing areas, restricting fishing season, and banning certain fisheries. However, fisheries management was hampered by lack of appropriate management regulations, enforcement and data on most stocks. Pollution and degradation of nursery areas were also affecting the productivity of fisheries resources. To achieve sustainable demersal fisheries, maintaining a healthy marine environment, reducing fishing effort, and strictly enforcing closed seasons and closed areas are needed. These measures are being implemented with varying degrees of success by all the countries.},

abstract = {INTRODUCTION The Epilithic Algal Community (EAC) of coral reefs are diverse assemblages of small filamentous green, red, blue-green algae ('turf species') and crustose coralline red algal. These have low biomass but show rapid growth rate (Klumpp and Mckinnon, 1989) and this algal community colonizes the reefs and serves as the primary food source for herbivores. The diversity and richness of reef fauna can also be attributed largely to the high productivity of EAC (Klumpp and Mckinnon, 1989); thus the EAC is the major source of food for herbivores such as damselfish, echinoids, surgeonfish (sohal and yellow tail), parrotfish and green turtles. The main algal functional form group (Littler et a¡.,1983) is the filamentous group. In the Arabian Sea, however, there is a diverse algal community of filamentous, sheet-group, coarsely branched group and thick leathery group due to upwelling, (Mardela, 1975, Jupp et al, 1996). The Gulf of Oman does not experience upwelling due to the summer S.W. monsoon, so in this part of Oman, because of the physical conditions prevailing, there are high salinities and temperatures in summer as well as wide temperature variation and, combined with largely sand substrates here, coral reefs are not as widely distributed as in many tropical seas and their growth and diversity is not as great. In spite of this, they still contribute a highly complex community (Sheppard and Salm, 1988). During the past three decades, many of the natural marine habitats in the world and Arabian Gulf in particular are being destroyed, degraded or are actually disappearing as a result of oil pollution, coastal infilling and other activities associated with industrial development. Because the EAC is very important for grazers, many studies on natural reefs and artificial reefs structures including oil platforms, piers, jetties and other coastal installations have been carried out (Seaman and Sprague, 1991). Artificial habitat enhancement has been practiced primarily to attract fishes in various parts of the world, however in Oman there are no studies yet that have been made to understand the mechanisms of attractive effect of artificial structures. In addition, few studies on reef coral community and no detailed study of EAC have been carried out in Oman with studies along the Gulf of Oman just mentioning few macroalgae and green filamentous algae, e.g. Entromorpha (Sheppard and Salm, 1988). On the Gulf of Oman coasts, only sparse clumps of larger macroalgae (>10cm) of sheet-group, coarsely branched and thick leathery groups are found (Mardela, 1975) with, for example, only scattered plants such as Padina and Halymenia (Cordero, 1992). In view of the importance of EAC on natural and artificial reefs this preliminary study will provide valuable baseline biological data about the growth of algae as well as the faunal assemblages that accumulate around artificial substrates. Data from this study would be useful to assist researchers in the future in monitoring herbivorous fish resources as well as the succession of communities developing on artificial reefs.},

The report points out the 'lagging pace and role of environmental planning', which has not been directly associated with economic and social planning, despite some limited efforts to control pollution. The report focuses more on the problems of resource utilization and sustainability (referring to land, water, fisheries, rangelands and forest), and calls for an improvement in the management and efficiency of use of these resources. The report emphasizes threats of continued population growth and limited water resources, and the need for land and water conservation. It recommends enhancing knowledge thorough conducting more intensive and continuous surveys and studies. The report also addresses historical sites and heritage preservation and the need to raise environmental consciousness and awareness. The report is rather vague in its recommendations - espousing conservation cooperation between ministries and prudence etc. etc. without any specific measures. One chapter outlines the responsibilities of the MRME, the need to inform the public, recruit more Omani expertise/train staff, enact more legislation etc. etc. Ministerial Decree 43/92: Establishment of a Permanent Committee of the National Conservation Strategy.
