Abstract

Indonesia's mangrove resources (soils and waters, flora and fauna, and as an ecosystem all are called as mangrove biodiversity) are growing in importance. As a consequence of past and present human utilization the mangrove resources have been depleted. Keen competition for use of the mangrove resources is apparent and is likely to intensify in the future. This policy document stresses the importance of mangroves for the Nation and the need for the Government to manage and protect them. A set of basic principles for the management and protection of mangroves is provided, together with an outline of some actions which local and central governments (Pemerintah Pusat dan Daerah) should take up in order to achieve a balance between the use of mangrove resources, their conservation and long term national development.

Abstract

Caulerpa and Caulerpella, the two genera belonging to the phylum Chlorophyta, order Bryopsidales distribute generously along the coast and islands of Vietnam. Based on the collected specimens, twenty-seven taxa belonging to the genus Caulerpa Lamouroux and one species of Caulerpella Prud'homme van Reine and Lokhorst are described and illustrated. The list of species includes: Caulerpa brachypus, C. cupressoides, C. fastigiata, C. lentillifera, C. mexicana, C. microphysa, C. nummularia, C. peltata, C. racemosa, C. serrulata, C. sertularioides, C. taxifolia, C. urvilliana, C. verticillata, C. webbliana and Caulerpella ambigua.

Abstract

Atmospheric boundary layer derived from NCEP/NCAR reanalyses for the period of 1974 to 2002 has been used as boundary forcings for the global ocean model Max Planck Institute Ocean Model (MPIOM). The ocean model is a curvilinear grid model, whose poles are located over mainland China and over the Australian continent, thus focusing on the maritime continent. The model simulates major Indonesian throughflow passages that focus on six cannels representing three inlets and three outlets (the Makassar, Lifamatola, Halmahera, Lombok, Ombai and Timor Straits). The model results have been validated using the Arlindo observation Project over the Makassar Strait in the period of January 1997 to February 1998, which fortunately was during a strong El Niño episode. The model simulation results were then investigated for their prediction capabilities of any of those channels in foreseeing the incoming southern oscillation events. Temporal correlation analysis with lag and advance time correlation methods were performed against simulated data at all levels on those channels. Variabilities in depth of 74 to 200m (thermocline depth) show the strongest correlation with SOI index (Darwin minus Tahiti mean sea level pressure). The temperature and salinity correlations with SOI are the highest with one-month in advance over Lifamatola Strait (0.77) and two-month in advance over the Makassar Straits (0.74). These significant correlations highlight the important of those two straits in prediction of incoming southern oscillation that usually leads to ENSO episode which brings most of the time devastating impact to economy, agriculture and ecosystem.

Abstract

In order to investigate spatial and temporal variability of dissolved organic carbon (DOC) and particulate organic carbon (POC), several samples were collected from five estuaries, inner part and outer part of Jakarta Bay. The samples were collected on 15 and 16 February 2007, a week after heavy flood in Jakarta Area, and on 16 May 2007. DOC concentration in February and May in Jakarta Bay ranged between 100-950 µg-C/l and between 0-850 µg-C/l respectively. POC concentrations ranged between 50-650 µg-C /l and 50-900 µg-C /1 in February and May 2007, respectively. Even though the concentrations between both periods were similar, the load of organic carbon from the land to Jakarta Bay showed a large contrast due to the different amount of freshwater input. The Total organic carbon fluxes from the rivers to the bay in February and May 2007 were 107.6 t d-' C-(ton per day Carbon) and 42.7 t d-1 C, respectively.

Abstract

This paper gave evidence of the occurrence of Thamnaconus modestoides in Indonesian waters. A specimen (271.15 mm SL) was collected from the Winenet fish market at Bitung, North Sulawesi in March 2008. It was reported being caught in the depth of 20-30 m, in association with other coral-reef fishes, despite the fact that member of Thamnaconus has been known as deep water species. The morphological features of this new record species were discussed and illustrated.

Abstract

Ovaries of Holothuria leucospilota consist of simple tubules, within which oocytes grew and reached maturity. The oocytes development started at the tubule lining and as the development proceeded, the oocytes increased in size and moved to the tubule lumen. An ultra-section-method was applied to describe ultrastructural changes in the oocytes during their development, leading to the knowledge on gametogenesis of sea encumber H.leucospiota. Primary previtellogenic oocytes embedded in tubule lining was the earliest stage, which were characterized by the presence of nuage. Prior to yolk formation, clusters of mitochondria appeared in the ooplasm. This may indicate the need for energy to produce yolk substance. When yolk bodies were common in vitellogenic oocytes, nuage became invisible and mitochondria were no longer in groups. As development progressed, abundant microvilli appeared on the surface of vitellogenic oocytes, but less common on postvitellogenic oocytes when maximum growth had been attained. This structure was suggested to facilitate size increase and functional efficiency of oocyte surface.
