MARINE RESEARCH IN INDONESIA (MRI) has been published since 1956 by Indonesia's oldest marine research institute, the Research Center for Oceanography of LIPI (Indonesian Institute of Sciences). MRI focuses on physical, chemical, biological, geological oceanographic as well as coastal management studies in the Indonesian seas and the adjacent Indo-Pacific region.

Abstract

A number of 137,870 freshly hatched larvae of Portunus pelagicus (L) were reared in one thousand litre container. The combination of Brachionus plicatilis and newly hatched nauplii of Artemia salina were fed to the larvae. The number of megalopa obtained was only 277. Ecological factor such as temperature, salinity, pH and dissolved oxygen were recorded. The effect of different food sources of the previous authors are compared. The detail description of the four zoeal stages and one megalopal stage are made and figured with emphasis on the number and type of setae on each appendages. A pattern of zoeal chromatophores is also sketched and described.

Abstract

Determination of  heavy  metal  content  (Hg, Pb, Cd, Cu, Cr, Zn) in some seafoods collected from  Muara  Angke  Fish  Auction  Place  were carried out during February to July 1979. The results showed  that Zn  content  in seafoods a nalyzed  was always much higher than the other heavy metals. The concentration levels of  the  six  heavy  metals observed were low. It is almost of the same level as the metal concentration of  other  seafoods  observed  in various parts of the world oceans, but still lower  than the maximum standard set  for human  consumption  as  established  by   Tasmania, Australia and  World Health Organization. The  mean  per capita  consumption of  fish  in Jakarta is only  about 165 g  per week, while  the  Provisional Tolerated Weekly Intake for Hg, set by WHO/FAO at 300 ug level, would be attained by consuming 1500 g Rastrelliger sp., or 698 gPenaeus setiferus, or 545 g Sepia sp., and or 1250 g Pecten sp.  Therefore,  at   present the  level of metal content in fishes sold at TPI  Muara  Angke  can be  considered  as  not  dangerous  to human health as long as these quantities are not surpassed.

Abstract

Currents and mixing properties on the sill of Ambon Bay were measured with drogues. Current speed of 0.62 m/sec was observed. A mixing model suggests material released on the sill would decrease by a factor of 2 x 104 in one hour. Drogue construction and data reduction methods are described.

Abstract

The semidiurnal tides of the Pacific and Indian Oceans penetrate deeply into the Southeast Asian waters. The tides of the Pacific Ocean govern the whole of the China Sea, the Philippines waters and the Sulawesi Sea while the tides of the Indian Ocean govern the Timor Sea, the Banda Sea, the Andaman Sea and the Malacca Strait. The Maluku Sea, the Makassar Strait and the Java Sea are the boundary region between tides from the Indian and Pacific Oceans. In the Java Sea the semidiurnal tide is produced mainly by the tide from the Indian Ocean. At the boundary region, the amplitudes are generally very small. As an example of a boundary region, the tides of the Sunda Strait are considered in some detail. An analytical solution of two overlapping standing waves, one wave resulting from open mouth reflection of a wave incident from the Indian Ocean and the other standing wave from open mouth reflection of a wave incident from the Java Sea, adequately describe the M2 tide in the Sunda Strait.
