PATTERNS OF RELATIVE GROWTH IN TROPICAL NERITIDS, NERITA UNDATA, BASED ON OPERCULUM ANALYSIS Uneputty, Prulley A.
Marine Research in Indonesia Vol 32 No 1 (2007)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Growth is one of the important events in the life history of an organism beside reproduction. The objective of the present study was to evaluate the possibility of using the operculum to determine the growth pattern of tropical neritids (Nerita undata). Shell and operculum dimension were measured using a vernier caliper to the nearest 0.01mm. The results showed that there was a relationship between operculum dimensions (length and width) and shell, and it was also shown allometric growth pattern. The study also indicated the relationship between operculum dimension and the shell parameters.

We wish not only to up-date the taxonomy used by DE MAN in his 1911 study but also to add to his list of species those new records of species from Indonesia based, upon collections made subsequently by various individuals and agencies. DE MAN reported that he had 113 species and 20 varieties of these shrimp from the Siboga Expedition; of these, 54 species and varieties have been reduced to synonymy in the subsequent years. In the present study these additional species are also being so reduced:Alpheopsis hummelinki SCHMITT (= Neoalpheopsis euryone (De Man)Neoalpheopsis hiatti BANNER (= N. euryone De Man) Synalpheus jedanensis De Man (= S. iphinoe De Man) S. miscellaneus De Man ( = S. neomeris (De Man) S. physocheles Coutiere (= S. triunguiculatus (Paulson) S. sluiteri De Man (= S. paraneomeris Coutiere) S. stimpsonii var. maldivensis C outiere (= S. stimpsonii ( De Man) S. streptodactytoides De Man (=S. streptodactylus Couti>re)From the post-Siboga collections, we list an additional 28 established species from Indonesian waters as well as two new species: Alpheus nipa and Synalpheus mortenseni; we also have reviewed the status of Alpheus (= Synalpheus) tricuspidatus Heller (1861) and consider it to be a nomen dubium. We now recognize a total of 145 species from Indonesian waters plus an additional 2 species left unnamed by De Man and by us.

Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Twelve species of Crustacea of the family Palicidae were collected from Indonesian waters. Together with two species from the Philippines and type specimens of Crossotonotus compressipes A. Milne Edwards, 18 73, are studied and Manella spinipes is used for comparison. Two new subfamilies, four new genera, and six new species are described and the type of Crossotonotus compressipes has been designated.

SEABIRDS IN THE BANDA SEA IN FEBRUARY/MARCH 1985 Cadee, G. C.
Marine Research in Indonesia Vol 27 (1989)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

Quantitative seabird data were collected in February/March 1985 in the Banda Sea. Comparison with similar data for August 1984 indicated no monsoonal influence on seabrid abundance; the median for both periods falls within the 1-5 birds per hour class.The area around the breeding island Manuk was relatively rich in both periods. Birds breeding here are "blue ocean" seabirds, foraging over large areas. Apparently, not food abundance but suitable breeding place determines their abundance here. Manuk has an enormous importance for the seabird population in the Banda Sea area, fortunately, it is a nature reserve since 1981. The breeding period on Manuk is not short and related to the NE monsoon, but extended over a larger period of the year. Manuk was known already as a breeding island in the 17th cnetury, but this knowledge was lost and only recently Manuk was "rediscovered" as such.A second relatively rich area occurred again south of Irian Jaya. Migrating birds dominated here. They probably visit this area because of relatively high food availability. Species differed for both periods. Streaked Shearwaters which breed on the northern hemisphere had in February/ March replaced the antarctic Wilson's Stormpetrel which abounded here in August 1984, but had now returned to its breeding area.

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.

OCEANOGRAPHIC CHARACTERISTICS OF KLABAT BAY, BANGKA ISLAND, INDONESIA Sachoemar, Suhendar I.; Kristijono, Agus; Yanagi, Tetsuo
Marine Research in Indonesia Vol 32 No 2 (2007)
Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

The oceanographic characteristics of Klabat Bay in Bangka Island of Indonesia were investigated by using a series of temperature, salinity, turbidity, TSS (total suspended solid), transparency, DIN (Dissolved Inorganic Nitrogen), DIP (Dissolved Inorganic Phosphorus), DO (Dissolved Oxygen) and chlorophyll-a data in the wet season (Northwest Monsoon) and dry season (Southeast Monsoon) of 2003, respectively. The observation results show that the hydro-oceanographic characteristics of Klabat Bay in the inner part and the outer part of the bay were dominantly influenced by the terrestrial and oceanic environment, respectively. High precipitation during the wet season decreased salinity, DO and transparency and increased total suspended solid (TSS), turbidity, DIN and chlorophyll-a within the bay. The reverse occurred during the dry season, except DIP.

Publisher : Research Center for Oceanography - Indonesian Institute of Sciences (LIPI)

The 2D horizontal model has been simulated to investigate a sedimentation and erosion pattern in the basin of Pulau Baai port ? Bengkulu Sumatera. The model was verified with observed data from the Indonesian Research Center for Marine Geology (Arifin et al., 2001). The simulation results of the hydrodynamic model shows a good agreement with the observed data. In -regard to the elevation of sea level, the difference between simulation and the observed data is about 4.6 cm, giving averaged error of about 2.93 %, and the difference in velocity is 6.8 cm/s or in the order of error of about 20.1 %. The results of the model on sediment transport qualitatively show comparable values to the observed ones, although in some parts of the area, the model is still to be adjusted. Simulation results show that the strong current occurs in the harbor channel during the time of spring flood tide with a speed of about 95.4 cm/s, while the ebb current is 54.1 cm/s. The results of the model on sediment transport show that the erosion area occurs in the northeastern part of the basin and sedimentation takes place in the southwestern to southeastern of the channel. The channel port is generally eroded, and sedimentation occurs in the mouth and the western part of offshoreward of the channel, and erosion is identified in the eastern part of the offshoreward of the channel.

The study on the fluctuation of dissolved nutrient concentrations and acidity (pH) in the Cisadane Estuary was carried out in May 2004 October 2004 and July 2005. Inorganic phosphate, nitrate and silicate of the surface water were analyzed, using Spectrophotometer and pH was measured with a pH meter. Generally the nutrient concentrations in the estuary were higher compared to those in the coastal and offshore areas. The concentrations were gradually becoming lower and lower toward the open sea. Their fluctuation depended not only on the environmental condition but also on the water volurrie from the land and the mangrove forest in that area.
