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

One specimen of Bodianus izuensis Araga and Yoshino, 1975, and three specimens of B. masudai Araga and Yoshino, 1975, were obtained from fish markets in Bitung and Kema, Minahasa, North Sulawesi, Indonesia, between Marchâ??July 2009. The specimens were caught from depths of about 20â??30 m at coral reef ecosystem around Lembeh Island and Kema. This is the first record of these species in Indonesian waters. Morphological features, diagnostic characters, and distribution are discussed and illustrated, and color photographs of the species are presented.

Abstract

More than 300 sea cucumber species have been recorded from Indonesian waters. This paper presents eight species which have been rarely reported. Actinopyga bannwarthi Panning, 1944, were found among fished sea cucumbers collected by fishermen in Kupang and Karimunjawa. Stichopus pseudohorrens Cherbonnier, 1967, was found in West Timor waters; Thelenota rubralienata Massin & Lane, 1991, and A. caerulea Samyn, Vandenspiegel & Massin, 2006, were collected from the reef in Halmahera, North Maluku. Four other species i.e. Bohadschia atra Massin, Rasolofonirina, Conand, Samyn, 1999; B. subrubra Quoy and Gaimard, 1833; Holothuria (Metriatyla) fuligina Cherbonnier, 1988, and H. (Thymiosycia) gracilis Semper, 1868, were discovered from Lombok waters. The latest mentioned species was also found among fished sea cucumbers in Karimunjawa. All species except T. rubralineata may be new records for Indonesia. In the case of H. (Thymiosycia) gracilis Semper, 1868, it was new record for Lombok waters, following its discovery from West Seram, Central Maluku.

Abstract

Bunguran waters is part of Natuna waters consisting of several small islands located in the southern part of South China Sea, between Sumatera and Kalimantan Island. This paper reported results of a study on spatial distribution and condition of coral reefs and other biota in Bunguran waters,i.e. percentage cover and diversity of coral species. The observation was conducted using line intercept transect (LIT) on eight stations distributed in Salor Island, Sedanau Island, Komang Island, Kumbik Island, Depeh Strait, Sabangmawang Island, Pulau Tiga Village and Tekolampak Cape. The results showed that the reef type of Bunguran were mostly fringing reef dominated by Porites cylindrica, P. lutea and P. rus. Porites spp. were evenly distributed in all location observed. A total of 115 coral species belonging to 16 genera were found and the percentage of living coral cover ranged from 43.20 to 63.53 %. Coral cover reached their maximum at 10â??15 meter depth and decreased rapidly coincident with the increasing depth. In general, the condition of coral cover was in â??goodâ? category with the average percentage living cover of coral was estimated 51.38%.

Abstract

Ceratium is non-toxic dinoflagellate which has been regarded as the most common bloom-forming species in the coastal waters around the world. Eventhough research and monitoring on phytoplankton In Jakarta Bay have been conducted for long enough, no specific attention has been given to Ceratium community. Therefore, a research was set up in order to understand the dynamic of Ceratium population and its regulating factors. A serial sampling was conducted in 10 stations during 2009 and 2010. Phytoplankton was sampled in horizontal towing using Kitahara plankton net (80 μm mesh size, 0.5 m mouth diameter and 1m length). Phytoplankton enumeration and identification were done by applying Fraction Method on Sedgewick Rafter Counting Chamber (SRCC). The result showed clear temporal variations in Ceratium absolute density, relative density, relative frequency and importance value. When phytoplankton bloomed in August 2009, no Ceratium bloom observed. High density of Ceratium was observed in November 2009 and May 2010, but it contributed relatively small proportion to phytoplankton as a whole (relative density <1%). Due to its low density and relatively limited distribution in Jakarta Bay, Ceratium may demonstrate limited ecological role to the phytoplankton community.

Abstract

Seasonal vertically integrated primary productivity (IPP) in eight stations of Inner Ambon Bay (IAB) and ninestations of Outer Ambon Bay (OAB) was estimated using the depth-resolved, time-integrated production model andvertical-a distribution model which was mainly dependent on chlorophyll-a profile. The profile was modeled as Gaussfunction in which its parameters were determined by minimizing the difference between the model and the averageof in situ chlorophyll-a concentration from 2008 to 2012. The data was collected by UPT BKBL-LIPI Ambonduring monitoring program in Ambon Bay. Based on this model, the results showed that the primary productivityduring the southeast monsoon was to some degree higher than that of other seasons. The main factors causing the higherIPP in this season were upwelling phenomenon and high rainfall intensity. From the results, it could be concludedthat run-off gave more impacts in IAB than in OAB while upwelling in Banda Sea affected the IPP more in OABthan that in IAB. Then, the existence of the sill located between IAB and OAB inhibited the mixing of IAB andOAB waters so that the levels of IPP and chlorophyll-a concentration in IAB were higher than that of in the OAB.
