INTRODUCTION In Indonesia, 13 provinces has been identified bordering directly with the SCS viz. Riau, Jambi, South Sumatra, Bangka Belitung, Lampung, Banten, DKI Jakarta, West Java, Central Java, East Java, West Kalimantan, Central Kalimantan, and South Kalimantan. Data collected from all 13 provinces consists of secondary and primary data. The secondary data will includes distribution areas of mangroves, geographical information (position, topography, total area of region and mangrove forest, and land- uses), biological information (flora, fauna, and aquatic biota), utilization, and socio-economic and socio-cultural aspects. Based on the evaluation of secondary data, primary data will be collected from selected provinces at the priority sites, e.g., West Kalimantan, DKI Jakarta and Bengkalis. Primary data will consist of biological, physical and socio-cultural information’s, and utilization. Sources of secondary data will be collected from Faculty of Forestry, Faculty of Fisheries of the Bogor Agricultural University (BAU) Bogor, the Centre for Marine and Coastal Resources Studies, BAU Bogor, LPPM Bogor, Birdlife International, Wetland International-Indonesia program, LIPI, Department of Forestry, Department of Home Affairs, Department of Marine and Fisheries and State Ministry of Environment. 2. MANGROVE ECOSYSTEM IN 13 PROVINCES SURROUNDING THE SOUTH CHINA SEA 2.1 Extend of Mangrove Forest Data on total area of mangrove forest in Indonesia are very varies from 3,177,700 ha (Bina Program Kehutanan 1973), 3,707,100ha (UNESCO 1979), 4,251,011 ha (Bina program Kehutanan 1982) to 4,355,553ha (Intag Departemen Kehutanan 1993). This is due to the facts that estimated value of mangrove forest are differentiated from one to another along with their different definition of the border zone they used.In 1989 to 1996, the Department of Forestry (1999) by using Landsat Imagery estimated that the total area of mangroves in Indonesia amounted to be 3,533,660 ha, consisting of protected forests (424,800ha), Nature Reserve and Recreation Forest (674,600ha), Natural Forest Production (583,600ha), Production Forest (372,400ha), Production Forest for Conversion (928,900ha) and Other Forest Land-use (449,300ha). Inventory of degraded mangrove forest conducted by the Department of Forestry (1999) shows that the mangrove forests in Indonesia covers an area of about 9,248,039 ha, consisting of state forest land (3,720,187ha) and non-state forest land (5,527,852ha). From the above figure, about 5,579,116.53ha (60.32% of the total mangrove forest in Indonesia, and 1,877,605.51ha and 3,701,511.02ha belong to state and non-state forest areas, respectively) is found in the provinces at surrounding the South China Sea (SCS). 2.2 Mangrove Forests for Forestry Exploitation The area of mangrove forest managed by Indonesian forest concessions (HPH, and HPHTI) at the surrounding SCS in 1982 amounted to be 226,000ha, and in 2000 it will be 172,143ha and managed by 9 companies. The mangrove forests managed by HPH used to be exploited for their wood as a raw material for chip industry. In some locations of West Kalimantan, the holders of HPH concession having less performance and their permission are terminated by the recent government policy (No log export regulation). 2.3 Mangrove Forest to be rehabilitated Rehabilitation activity for mangrove forests commencing since the early of 1960 in Java and conducted by Perum Perhuani (The State Forestry Corporation). In connection with conserving of the mangrove forest and referring to needs of the people for agricultural lands, Perum Perhutani has developed a tambak tumpang sari system or tambak empang parit, call as silvo-fisheries. It was reported that about 20,000ha of degraded mangrove forests in the northern coast of Java have been rehabilitated successfully with Rhizophora spp. and Avicennia spp. For Segara Anakan, 105ha of degraded mangrove forests have been rehabilitated too, with Rhizophora sp. and Bruguiera gymnorrhiza. DitJen RLPS of the Department of Forestry have been rehabilitating the degraded mangrove forests in 12 provinces with a total area of 15,830ha. Table 1 shows Extent, Distribution and Number of Changed Mangrove Forest Area in the South China Sea (at 13 provinces in Indonesia) during 1982–1999.

  • The Pandas Are Coming, the Pandas Are Coming!!! by DRAS Member Derek P.S
    WTFish?: The Pandas Are Coming, The Pandas Are Coming!!! by DRAS Member Derek P.S. Tustin ometimes it is interesting living in the Greater Toronto Area, isn’t it? S Recently deemed to be the fourth largest city in North America (leaping past Chicago by 84,000 people) behind Mexico City, New York and Los Angeles, we truly are a world class city. (Interestingly enough, the Greater Toronto Area, that being the recognized metropolitan area of the city and those living in the immediate suburbs, is actually the 51st largest metropolitan area in the world with 6,139,000 people. Tokyo is first with 37,126,000 and Chicago is 28th, with 9,121,000(1). So we still have some catching up to do...) And since I seem to be heading off on tangents today, have you ever considered what makes a city “world class”? According to some, it is a “city generally considered to be an important node in the global economic system.”(2) Given Toronto’s impact on the national economy, and the subsequent influence within the international economic community, it can easily be argued that Toronto is such a city. But there are also cultural factors that come into play. Toronto is blessed with many such attractions, but the one that stands out in my mind is the Toronto Zoo. Sometimes I think we all take for granted what a wonderful facility we have right next door. The Toronto Zoo is consistently ranked as one of the top ten zoos in the world (3, 4, 5), and acknowledged as being one of the largest zoos in the world (6).

  • Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998
    Tampa Bay Benthic Monitoring Program: Status of Middle Tampa Bay: 1993-1998 Stephen A. Grabe Environmental Supervisor David J. Karlen Environmental Scientist II Christina M. Holden Environmental Scientist I Barbara Goetting Environmental Specialist I Thomas Dix Environmental Scientist II MARCH 2003 1 Environmental Protection Commission of Hillsborough County Richard Garrity, Ph.D. Executive Director Gerold Morrison, Ph.D. Director, Environmental Resources Management Division 2 INTRODUCTION The Environmental Protection Commission of Hillsborough County (EPCHC) has been collecting samples in Middle Tampa Bay 1993 as part of the bay-wide benthic monitoring program developed to (Tampa Bay National Estuary Program 1996). The original objectives of this program were to discern the ―health‖—or ―status‖-- of the bay’s sediments by developing a Benthic Index for Tampa Bay as well as evaluating sediment quality by means of Sediment Quality Assessment Guidelines (SQAGs). The Tampa Bay Estuary Program provided partial support for this monitoring. This report summarizes data collected during 1993-1998 from the Middle Tampa Bay segment of Tampa Bay. 3 METHODS Field Collection and Laboratory Procedures: A total of 127 stations (20 to 24 per year) were sampled during late summer/early fall ―Index Period‖ 1993-1998 (Appendix A). Sample locations were randomly selected from computer- generated coordinates. Benthic samples were collected using a Young grab sampler following the field protocols outlined in Courtney et al. (1993). Laboratory procedures followed the protocols set forth in Courtney et al. (1995). Data Analysis: Species richness, Shannon-Wiener diversity, and Evenness were calculated using PISCES Conservation Ltd.’s (2001) ―Species Diversity and Richness II‖ software.

This research was conducted in the tourist area of Benan Island, Lingga Regency, Riau Islands Province, using a mixed method, which is a combination of qualitative and quantitative research methods. The results of the analysis conclude that fisherwomen are said to be effective in conducting extension education to support sustainable eco-tourism management in the village. This is seen from the effectiveness value of several components in the effective category range (330-540), among others the frequency of Extension conducted by fisherwomen to the family environment and surrounding communities has a value of 380, the value of the level of knowledge about the goals of eco-tourism management obtained by the community from extension communication is 370, and the value of implementing sustainable eco-tourism management by the surrounding community of 360. Extension communication methods with individual direct dialogue are considered more effective (380) compared to direct group dialogue (253).

  • Notes on Fishes of the Genus Brachygobius
    LIBRARY OF THE UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN 590.5 FI V.39 cop. 3 NATURAL HISTORY, SURVEY •- -f 9 14 FIELDIANA • ZOOLOGY '^ P- Published by CHICAGO NATURAL HISTORY MUSEUM Volume 39 April 25, 1968 No. 14 NOTES ON FISHES OF THE GENUS BRACHYGOBIUS Robert F. Inger ^ Curator, Division op Rbptilbb and Amphibians The gobies of the genus Brachygobius Bleeker inhabit both brack- ish and fresh waters of the Oriental region. All the species are small (rarely over 30 mm.) and banded with black and yellow. Material recently acquired by Chicago Natural History Museum from North Borneo contained fishes apparently belonging to a new form. This discovery led to a study of previously described species with the result that B. aggregatus Herre was found to be a composite species in- cluding a new one from Borneo. These two forms are described in this paper. The generic diagnosis of Brachygobius given by Koumans (1953) contains several statements requiring modification. According to Koumans, predorsal and opercular scales are always present and the anal and second dorsal fins have from seven to ten branched rays. Actually, not all species have opercular scales. In some species pre- dorsal scales may be present or absent, depending on size; in others the predorsals seem to occur on all individuals; in still others they are always absent. The anal and second dorsal usually have seven or eight branched rays, but in two species six is the common number. In general, Brachygobius has a short heavy body, cylindrical ante- riorly, compressed posteriorly. The head is flattened between the eyes, which are always larger than both the snout and the inter- orbital.

Se encontraron resultados positivos en un 15,263% para el total de las hembras analizadas en dos especies: Echinolittorina ziczac de la Isla del Carmen (IRLP = 2,439) y Nassarius (N.) vibex del estero de Sabancuy (IRLP = 1,0741). Estos resultados demuestran una sorprendente salud con respecto al TBT en las aguas de la laguna de Términos a pesar de la actividad industrial y desarrollo social de esta región. Palabras clave: TBT, imposex, gasterópodos ABSTRACT A study on the presence of tributyltin (TBT) was conducted through the analysis of the phenomenon of imposex on three gastropod species into the aquatic environment of the laguna de Terminos, Campeche for assessing the females masculinization as a direct result of the quantitative presence of the TBT.
