Abstract

During summer of August 2000, the behavior of 210Pb was studied in off coast Ulsan, Gampo and Pohangwaters, Korea as an area potentially upwelling occur. Water samples were collected vertically inshore andoffshore at each station. The highest of 210Pb activity occurred in the surface layer as derivate fromatmosphere and then decreased with increasing depth. The lower 210Pb activity in bottom layer was causedby scavenging of particulate matter and strong affinity of unsupported 210Pb to soil and sediment particles.In middle layer of the water column activity of 210Pb fluctuated due to water masses of North Korea ColdWater (NKCW) that flows in this layer. The water mass of NKCW also affect on increasing dissolved oxygen(DO), where the highest of DO concentration occurred in this middle layer. The vertical distribution of 210Pbin the study area was generally not different between inshore and offshore, and the activity of 210Pb thatdetermine also was not significant different with previous studies.

Abstract

Indonesian marine environment is one of the most vulnerable waters from oil pollution in the world. Therefore, a hard effort to minimize oil pollution impact is really needed. Physical and chemical approaches have been already popular to combat oil pollution; one of the other promising techniques is bioremediation, the use of microorganism to detoxify or remove pollutants. Research and application of bioremediation on soil environment has been started in Indonesia; however, in marine environment it is still need to be studied due to more complicated aspects and also difficulties. Development of bioremediation study on marine environment in Indonesia has been started from enumeration, isolation and identification of oil degrading (hydrocarbonoclastic) bacteria. Researches on taxonomic and functional genes have been conducted. Biostimulation and bioaugmentation studies are ongoing research which conducted from laboratory scale and microcosm scale to field experiment (sand column). To have a manual or guidelines on conducting bioremediation in marine environment is not easy and still many steps have to be done. Several aspects concerning with this study such as the diversity of polluted sites characteristic, oils characteristic, oceanographic conditions and engineering has to be studied comprehensively.

Abstract

Indonesia is a maritime country, composed about 17,500 islands. It has a great endeavor of open waterresources such as river, lake, dam, pond, swamp, etc. which are spread over the country. Multi-tribes and –races are attributed to its habits, tradition, and culture of the communities lived. Given such large territory,especially Indonesia is formed of thousands island, it will be costly to set a formal enforcement andsurveillance in securing the open-access resources (like fisheries, water, etc). Fortunately, each communityhas an indigenous or traditional system to manage the resources. For example: Ikan Larangan (in WestSumatra), sasi (in Maluku), Subak (in Bali), Sedekah Laut (in Java) and so on (Susilowati, 1996; 1999).Rather than waiting a complete formal resource management (and need to be set up by the government) anddo not know when will be effectively apply, thus it will be more reasonable and timely to revive thetraditional system of resource management belongs to the respective community. In short, communityinvolvement in resource management is urgently encouraged, particularly in developing country withlimited budget like Indonesia. This paper is attempt to compile an experienced of Co-management approachto manage the open water resource done by Susilowati (1999, 2002, 2004, 2006, 2007). An institutionalanalysis (Pomeroy and William, 1994) and Pinkerton (1989) with necessary modification were applied tothe respective studies. The results indicated that there is a fairly prospect to empower the competentstakeholders (community, government, private, independent parties) to be involved in managing the openaccessresources. However, all parties need to be encouraged for a high intention in participation,commitment and somehow to create their sense of belonging to advocate the resource management. It iseasy to say but hardly to be materialized all the things for Indonesian context, except the leaders (formal andinformal) in the respective region are really committed to conserve the resource.

Abstract

To study the gear selectivity on scad Decapterus macarelus fishing experiments using drift gill net withdifferents mesh sizes were conducted in Kayeli Bay Buru Island Maluku. To obtain data of fork length sizecomposition, drift gillnets were operated at fish agregation devices along night time. The selectivity of driftgillnets for scad were estimated with Kitahara’s method. Mesh selectivity by a drift gillnet used for scadDecapterus macarelus shows a peaked curved with the efficiency at the peak of mesh selectivity increasingin proportion to the mesh size. The optimum size selectivity (fishing efficiency) of scad are ratio of 185 mmfork length class and 38 mm mesh size, 225 mm and 45 mm mesh size, and 255 mm and 51 mm mesh size.

Abstract

Biometry of Artemia franciscana from three different batches were characterized under laboratoryconditions. The results from diameter measurement of cyst from PR, SI and AS batches were 240 μm, 238μm and 245 μm respectively. The diameter of decapsulated cyst from the same batches were 223 μm (PR),221 μm (SI) and 220 μm (AS). The length of Instar I nauplii from PR, SI and AS batches were 476 μm, 497μm and 498 μm. Hatching efficiency after 48 hours of incubation were 2.76 x 105 nauplii/g cyst, 2.80 x 105nauplii/g cyst and 2.90 x 105 nauplii/g cyst from PR, SI and AS batches. The statistical analysis of theresults indicated that there were no significant differences (P=0.1) in diameter of cyst, length of Instar Inauplii and hatching efficiency of cyst. The hatching percentage of cyst from AS batch at 24 hours (89%),and respectively 48 hours (91%), was significantly higher (P=0.1) than those of SI (83% and 88%) and PR(74% and 80%).The hatching percentage of cyst from PR batch was significantly lower (P=0.1) than SI.

Abstract

Continuous mangrove ecosystem degradation and coastal erosion is observed along the coastline of SungaiHaji Dorani, (N 03038’36.6”; E 101000’37.3” to N 03038’37.9”; E 101000’34.0”) Selangor, PeninsularMalaysia. Foreshore mangrove plantation challenges below mean sea level are in progress in this highenergy coast. There are interventions of gabion breakwaters and geo-textile tubes to alleviate the wavevelocity striking the shore. The area between the breakwaters and coastline is chosen for mangroveplantation. The soil is fluid silt sludge with average clay, silt and sand proportion of 43.03 %, 351.8 % and5.14 % respectively. The maximum height of the tide recorded onshore was 2.8 m and in the middle of theplantation area the height of the water flooding is ±3.5 daily during tides. Number of plant species on theSAUH concrete revetment is 43 with 12 mangrove species and on the fringe reference mangroves is 27 with8 true mangrove species. This paper explains the method to identify the potential location for mangroverehabilitation, possibility of establishing mangroves on the seafront in the chosen area and conservation ofthe existing strip with 14 mangrove species. Overall sediment accretion since May 2008 is ±0.0037cm perannum which is considerably negligible. Opening out the earthen bunds along the coastline is the actualsolution for natural mangrove translocation and stabilization in this particular coastline, however, it is notpractically possible. Hence, we have studied an alternative strategy of rehabilitating mangroves at theelevation of +0.5 m to 1m MSL along this shoreline and also in an engineered firm sediment filled zone. Wepropose carrying out hydrological restoration in the natural habitats for survival and further naturalcolonization of mangroves.

Abstract

Fisheries management at Indonesia during the time is relatively responsive to unsustainable management.This caused by this management which is not yet considering population dynamic aspects, such as intrinsicgrowth rate, catch ability of fishing gears and carrying capacity. The objectives of these researches are todevelop and decide of the intrinsic growth rate and catch effort effects to white shrimp population dynamicat Riau Province. Modeling was conducted to growth and harvesting model with numerical simulationtechnique. The result of numerical simulation represents that intrinsic growth rate of white shrimp is equal0.88 tons/years and carrying capacity is equal 38,023.26 tons. Existence standard effort 54,447 trips/yearscause decreasing maximum population growth became 10,941 tons of population with growth rate 2,831.3tons. The optimal and sustainable management of white shrimp fisheries at Riau Province must be considerpopulation dynamic aspects.

Abstract

Sediment dynamics and the hydrodynamics of the environment cause the complexity and variability inanimal-sediment relationship, both in spatial and temporal. This study is focused on the response ofmacrobenthic fauna to environmental disturbance caused by fish farming using their trophic structure.Their changes in trophic structure can be used as an indicator of disturbance. Eight control sites and eightfarm pontoon sites were samped in a full year period. Two stations at each site were sampled five timesthroughout the year with four replicates. Macrobenthic abundance was categorised based on six majortrophic groups: carnivores (CAR), herbivores (HER), omnivores (OMN), suspension feeders (SF), surfacedeposit feeders (SDF), and subsurface deposit feeders (SSDF). The Infaunal Trophic Index (ITI) andShanon-Wiener diversity index (H’) were used to assess the degree of environmental disturbance caused byfish farming based on trophic structure. The relationship between ITI and H’ was assessed usingSpearman’s rank order correlation (rho). The result showed that the abundance of deposit feeders wassignificantly higher at the farm sites than at the control sites, suggesting that food availability is morevaried and abundant at farm sites than those at control sites. The results of the ITI indicate that the entiresampling sites have been moderately disturbed over the sampling period, with the exception for site BC8.Variability of Shanon-Wiener diversity index (H’) spatially and temporally seems co-vary with ITI, owing tothe influence of taxa richness and evenness.
