Abstract

Information on condition and spatial distribution is essentially needed for better coral reef management. In order to provide the information, classifications of reeff morphology s is one way to obtain the physical condition of the reef. This method is relatively straightforward; with the means of remote sensing imageries, because the standard already exists. One of the challenges is what is the best way or detailed steps required to identify these highly variable objects. This exploratory research is aimed to develop identifications criteria of reef morphology s. Sikka district was chosen study area because it has some type of small islands with high diversity of reef morphology s. Each reef morphology s were analyzed to get a general habitat charasteristci which might be relevenat to coral reef management needs. Identificaton was performed visually with geomorphological approach. Indetifications result are qualitative, quantitative and spatial, and presented in teh forms of descrictive elaboration, tabular, and map

Abstract

Marine biodiversity at species level is crucially important ini ecological  assessment and aceosystem management. Data on coral richness, however, are very race for many reefs in Indonesia, due to low number of available coral taxonomist in many provinces and districts. The objective of present sudy was to find a regression model for estimating species richness of Scleractinian corals, based on line-intercept-transect data. Wakatobi and Pangkep (Pangkajenne Kepulauan). The result showed that coral species richness can be estimated from three predictor variables: coral acroporiid covers (CAC), coral masive and submassive cover (CMS), and number of coral genera(CGR). Develop multiple regression model showed considerably high cooficient of determination (73.55%) in estimating coral species richness. Model validation using data from coral reefs on Lembaga waters showed that the model worked well, i.e. estimated and in situ recordered species richness are strongly correlated.

Abstract

Latest stage development of recruit coral community in concerete artificial reefs were observed for nine months (from October 2009 to July 2010) by visual cencus and underwater photography methods. Amounts of 10 units of concrete artifical reef deployed in Pramuka Island waters and Gosong Pramuka in 2011 were used as an objects in this reseacrh. As a comparation, the conditios of coral coverand reef fishes in natural reef were observed by line intercept transcet, visual census, and underwater photography methods. In order to measure coral coberage area  we used a ImageJ 1.42q software. In march 2010, amounts of 457 coral colonies from 21 genera and 216 coral colonies from 16 genera were found on artifical reefs surface in Station 1 (Pramuka Island) and Station 2 (Gosong Pramuka) respectively. Number pf recruit coral colonies was dominated by genus Porites. Pocillopora, and Chypastrea. In july 2010, the precentage of coral cover on cencrete artifical refs reaches 41.46 ±13.37% (±SD) in Station 1 and 20. ±6.08% (mean ±SD) in Station 2, while the percentage of coral coverage on natural reefs were 23.14% and 40.43% in Station 1 and 2 respectively. Genus Porites become the most dominant genus in both of stations in terms recruit coloby abudance and percent cover. This result shows that concrete artificial reefs can effectively use to create new habitat of corals, coral fishes and other biota particularly in degraded coral reefs ecosystem.

Abstract

Research concerning survival and growth of coral recruits has been conducted in Pari Islands, Kepulauan Seribu, Jakarta , from March  to November 2010, which purpose to determined the effect of biotic and abiotic factors on coral recruitment survival and growth. We observed two life form of coral recruit, Massive and Branching within a transcect area of 2 meter x 70 meter at 5-7 meter depth. Furthermore, for each life form, the coral recruit was grouped in 3 classes, Small(<3cm), Medium (3-6 cm), and large (> 6 cm and 10cm) and all colonies were marked by plastic tag. Coral recruits in this study site were diverse with species diversity reaching 14 genera from 9 families, consisting of 9 genera at ST1-Pari site and 8 genera at ST2-Tikus Site which there were 2 genera founded at each site, Porites and Fungia, and genera of Faviidae were the most dominate, Diversity of coral recruits was moderate level with 1,85 diversity index at ST1-Pari Site and 1,59 at ST2-Tikus Site. The growth of coral recruitment was variated, according to the colony form and size class, which the highest growth of massive colonies to 4.4 mm/month in the small size and branching corals. Survival fo medium size colonies was lower compared to the other categories.

Abstract

Coral Reef Information and Training Center (CRITC) is one of Coral reef Rehabilitation and Management Program (COREMAP) units which serve on coral reef of areas under the Research Center for Oceanography “ Indonesian Institute of Sciences. Data Suplplied to the CRITC are collected from baseline studies and regular monitoring. At the second phase of COREMAP, CRITC are collected from baseline studies and regular monitoring. At the second phase of COREMAP, CRITC has conducted data grouping and processing for three major components: reef-helath, community-based fisheries monitoring (creel), social-economy plus spatial data. However managing these data was difiult due to former to way of data management: manual, scattered, non-centralized and non-standardized. It was then ebident an intergrated information system is needed to reduce data redudancy, allow easy data accessing and linking. In addition the new system should minimize changes to existing system. This way, data collection process is unaffected but a the same time system functionality is enhaced. To achieve the above objectives, CRITC has developed Coral reef Management Information System (CRMIS). CRMIS provides an intergrated , practical, easy-to-use online information system that support coral reef data management. CRMIS itself is a web 2 based application, bilingual (Indonesian and English), Support Web GIS (Geographical Information System), ad-hoc query (user-created search), time-series analysis and report. Web GIS faciltates online interactive thematic maps portraying reef health condition which is linked with other non spatial data (percentage of coral cover, cacth per unit effort or cpue and net-income of COREMAP locations). Hence CRMIS enabled stakeholders to easily get customized information for better reporting, research,planning and decision making.

Abstract

The Banggai cardinalfish (Pterapohon kauderni, Koumans 1933),often refered to as BCF, is a restricted range coral reef associated fish endemic to shallow waters (0-5m) arround the Banggai Archipelago, Indonesia. Listed as Endangered un the IUCN Red-List. In 2007 a national BCF Action Plan was developed , and a Distrct MPA was established by decree of the Banggai  Kepulauan District Head, consisting of a network of 10 islands. For 2 of these P. Kauderni conservation in the main management target. We reviewed available phylogenic, genetic and biogeographical data, and examined the MPA network from the viepoint of P. Kauderni genetic diversity conservation. With no pelagic phase and high fidelity, the Banggai cardinalfish population exhibits a level of genetic structure unusual in a marine fish. Several genetically distinct sub populations have been identified. It was concluded that management units should be based  on genetically detrmined sub-populations (stocks). Critical knowledge gaps and several research pririties were identified. In particular , we conclude that a researh programme is necesary for the identification and characterisation of these genetically determined units from biological (including genetic), ecological (e.g. habitat/micro-habitat) and socio-economic (including fishing ground) aspects. We propose to provide management support through the use of the spatial analysis tool MARXAN combined with a GIS database to produce science-based zoning options with management units/targets based on genetic population structure.

Abstract

Raja Ampat located in West Papua province is well know as region that has high diversity of marine life, particularly corals and coral fishes. Manu parts of the coastal and marine areas in the regios have been protected through the development of marine protected areas (MPAs). It has been known that destructive fishing has been one of the cause of the destruction of coral and marine life. The present study aims to identify the existence of the illegal fishing pratice by conducting a field survey using observatory and interview techniques, As many as 102 fishers from 10 villages were interviewed. The results of the study revealed that prominent existed destructive fishing was the use of explosive materials (fish bomb) by fisher from outside the Coremap areas (especially from Sorong). Local fisher used fishing gears, such as spears and handlines to catch fish in coral reefs in wich the impacts on coral may be minimal. Several factors that may sustain destructive fishing practice existing in the Coremap areas were ineffectiviness of monitoring, controlling, and surveylance (MCS) by government and localcommunity, lack of law enforcement and low economic capacity of community

Abstract

One of the competencies in to develope the knowledge and to build up public awarness on the importancy of the sea human life, is the sustainability and management of coasltal and marine ecosystems, ie.: the mangrove, seagrass, and coral reefs ecosystems. From those three ecosystems, the coral reef is the most dominant as the habitat of various  fish species. Because of that, the coral reefs deserves a more empathy and love feeling to raise the appreciation of the community on the  Coral reef ecosystems conservation. These appreciation and awareness will be most effective to be introduced since theearly ages. This process is necessary to establish to corall reef literacy. this study was aimed to examine thi concepts of coral reefs ecosystem to be offered in the prymary school.The selected concepts has to be considered through its acceptability, subtantive supports, and other influencing factors, leading to priorotizing of workable concepts variables. As a technical approach for decision making, descriptive, quantitative and interpretative analysis were aplied accordingly, througs three stage of research: (1) The oceanic concepts of Indonesian childresn among inland  and coastal community form 8 to 12 years old (case study)., (2) The profil of coral reefs world through the eyes of Indonesia elementary s prepective (case study: 4th, 5 th, and 6th graders)., (3) Concepts model of coral reefs knowledge for marine science learning program in the primary school. I general this research reveal that the development of coral reefs literacy based on competency for 4th, 5th and 6th graders needs to be implemented and could be divided into three phases: phase I, Understanding; Phase II, Application and Phase III, Analysis.
