Abstract

Destructive fishing such as using cyanide in capture of ornamental fish has caused damage to the coral reefs, this is suggested the use of clove oil which considered eco-friendly fishing. This study aims to analyze the changes of color, zooxanthellae density and mitotic index of coral Porites lobata after exposure to several concentrations of clove oil. Experimental design was a factorial design, which consists of six concentrations and five time treatments with 3 replication. Coral was placed into the 1.0x0.5x1.0 m aquarium that contains clove oil solution in different concentrations (control, 20, 30, 40, 50, and 60 ppm) for 5 min and then transferred to a tank containing clean seawater for 60 seconds and then removed to tanks for the recovery process. Observation was made everyday for coral color changes in 17 days period and on day 1, 5, 9, 13 and 17 for zooxanthellae density and mitotic index.  The results showed that the were no changes in Porites lobata colors until the 17th day after exposure to 20–60 ppm of clove oil and there was no significant difference in the zooxanthellae density and mitotic index of the Porites lobata on concentration variation, while zooxanthellae densities and mitotic index showed significant difference on time (day) variation. This suggested that exposure to clove oil at  a concentration of 20–60 ppm did not affect the color change, zooxanthellae density and mitotic index of Porites lobata.

Abstract

Preliminary surveys for coral disease were conducted in October 2011 as part of the first Indonesian coral health workshop in Barranglompo Island, part of the Spermonde Islands, South Sulawesi, Indonesia. Previous coral disease surveys conducted in Wakatobi National Park (WNP), South-East Sulawesi in 2005 and 2007, and qualitative surveys in April 2011, are included here to provide an overview of what is known about coral disease in Sulawesi and to compare results with reports from other regions of the world. On all reefs surveyed in these two locations, levels of coral disease were relatively low compared with global averages from other locations. In preliminary surveys of Spermonde reefs, the most significant syndrome detected was white syndromes, which affected 13 different coral genera. The most significant syndromes detected in WNP were white syndromes, black band disease, and a yellow tissue discoloration syndrome that was similar macroscopically to Caribbean yellow band disease. Although overall coral disease prevalence was low in Barranglompo and WNP, there is the potential for greater impacts of coral disease as anthropogenic influences increase and the oceans continue to warm. This study provides preliminary baseline data on the impact of coral disease within the reefs of Sulawesi, Indonesia, the center of coral reef biodiversity.

Abstract

Giant clam (Tridacna sp) are one of the endangered species listed on the Red List of Threatened Species by the IUCN, which is grouped at CITES. In Indonesia, efforts to protect it have not beeneffective due to a lack of supervision and law enforcement support. The local community of Toli-toli in the Province of Southeast Sulawesi, has made efforts to save the species from exploitation and poaching. This effort was supported by the village head and the local community by the establishment the Giant Clam of Marine Protected Area (MPA). Data was collected by in-depth interviews and focus group discussions. The sampling consisted of the village head, community leaders, fishermen and clam conservation groups. Data analyses were performed using qualitative descriptive methods “ Analysis Individual Interest Matrix (AIIM) and Analysis Hierarchy Process (AHP) - to determine management priorities to protect the clams. The results show that through community-based management, a local village community accepts the establishment of the MPA. The total area reserved for this MPA was 60 hectares, spread over 4 sites of clam translocations. MPA management would have 5 priorities: formal legalization of MPA (0.281), zoning areas (0.253), management institution (0.181), community-based ecotourism (0.175), and development of alternative livelihoods (0.110). This model is an alternative one in the effort to protect clam species and to improve the coastal community welfare around the MPA sites.

Abstract

Research on the abundance and distribution of coral disease has been implemented since June andJuly 2011 to determine the preliminary abundance of coral disease on several islands in the Thousand Islands, Jakarta. Observation method used was a 20m-belt transect with 1 m width to the left and right, and 3 replicates. Transects placed on the reef flat with a depth of 0–3 m, and a record number of infected colonies of BBD. The results show that type coral diseases of BBD found in many high coral covers and where Montipora sp dominant at that location. Generally, highest abundances found were at northern of Pramuka Island (0.15 col/m), eastern of Pari Island (0.092 col/m), Penjaliran Island (0.092 col/m), and Tikus Island (0.085 col/m). Statistical test by ANOVA obtained that abundance of BBD was significantly different between groups of study sites, i.e. the distance between the nearest and middle sites, and between the nearest and farthest distance from the mainland of Java Island (significantly difference with value respectively 0.030 and 0.025; confidence level 5%). Meanwhile, the sites between middle and farthest show no real difference. Based on climatological data, the increase in temperature in March and July could lead to coral diseases that occured in the Thousand Islands region.

Abstract

This is research aimed to (1) analyze community’s perception regarding the existence of coral reef resources in Mattiro Baji Village, (2) analyze various issues in relation to establishment and management strategy of community-based Marine Protected Area (MPA). This research uses in-depth interview and Participatory Rural Appraisal (PRA) methods. From the analyses it is concluded that (1) the perception of local community regarding the importance of coral reef ecosystem value is excellent, even though it is not fully implemented yet in their daily life, (2) Several key factors supporting the existence of CBMPA in Mattiro Baji include (a) community understanding about the need to MPA is relatively good, (b) there is a valuable lesson learned regarding the destruction of coral reef ecosystem, and (c) the unity spirit among community to protect and manage the resources from outsiders. Various strategies need to be conducted for the MPA development such as the establishment of waters boundary and the use of village area, zonation management, monitoring and surveillance of areas utilization and MPA, the increase of community understanding to environment, community efforts and incomes through alternative income generation activities.

Abstract

The purpose of this paper is to analyze the efforts of increasing conservation-based fishery management by applying a certification system and providing recommended formula of strategic policy in the continuing fishery certification system. Nowadays, the degradation rate of coastal and marine resources is so quickly with a very high damage level. Along with the world’s fishery policy which refers to the Code of Conduct for Responsible Fisheries, there are some obligations from fish producer countries to apply the use of fish and reef resources more environmental-friendly, one of them is by doing the certification towards the environmental management and fishing techniques. Ecolabel certification is a certification system to indicate that the certificated product was produced by following principles of environmental preservation and sustainable process. Thus, the certifier can help consumer to distinguish between certified product or non-certified product. The ecolabel certification are based on three main concepts: the natural resources for sustainable production, ecological, and sosio-cultural. Indonesia must apply the fishery certification system because the damage level of coastal and marine ecosystems in Indonesia is very high. This paper explains the effectiveness of marine ornamental fish certification that has been conducted in Pangkep Regency, Indonesia. The program was conducted by a local certification department, International Certification Quality, in collaboration with COREMAP by using adopted standard of Marine Aquarium Council (MAC).

Abstract

Damselfishes are an abundant, specious group of fishes that are important functional components in coral reef systems. Many of these species have strong habitat associations thus are sensitive to changes in the coral reef habitat quality. The purpose of this study was to investigate the distributional patterns of damselfish in different coral reef zones in healthy and degraded reefs. Benthic and fish transects were carried out in different reef zones from the patch reef to reef slope. Life history changes and microhabitat associations were recorded for all damselfish species. Higher numbers of both adults and juveniles were found on the healthy reef, Hoga. Damselfish communities were also more distinct between zones on the healthy Hoga reef compared to the degraded Sampela reef likely attributed to the more homogenous benthic composition among zones in Sampela. Significantly lower numbers of juveniles were found on the reef slope, with no significant difference between the other three zones, indicating ontogenetic migration of adults into deeper zones. When abundance was analysed at species level more distinct patterns were observed. Damselfish clearly have preferences for particular microhabitat types, and this influences their overall distribution on coral reefs. Changes in fish communities between healthy and degraded reefs were observed as well, though it is less clear how this influences the dynamics of coral reefs. This study further reiterates the strength and nature of habitat associations of damselfish and provides insight into potential changes in distribution patterns when there is a decrease in overall habitat quality.

Abstract

The study in the Southeast Asia regarding fisheries, tourism, including aesthetic value estimated the sustainable economic benefits per km² of healthy coral reef ranging from US$23,100 to 270,000. The question is how this goes for limited area consisted of mangrove-sea grass-coral reef, which found in many coasts throughout Indonesia archipelago. Should it be ignored? The purpose of the study was to indicate the existing economic values of limited coastal area consisted of mangrove, sea grass be, and coral reefs of the Ringgung coast of Pesawaran, Lampung Province. The results indicated that from coast length of 2.4 km, the total area of the wetland is approximately 78 ha consisted of 4.75 ha of mangrove, 22 ha of sea grass bed, and more than 50 ha of coral reefs. The economics values of the area study were predominantly used for grouper farms, with more than 15 individual farms, recreation, and Rizhopora culture (for seedlings) operated by locals. The economic values of the Ringgung coast by using direct use value of the grouper farms indicated that the yearly fish productivity was grossly of US$ 640,985. This number could be added up by the other economic values, such as recreation and saling of Rizhopora seedling. We can conclude that this economic values provided by the coastal ecosystem should be made to conserve the existing ecosystem. Besides, in order to maintain sustainable economic of the ecosystem, some consideration should be made in regard of carrying capacity for grouper farms in the area study.
