As a result of high levels of exploitation, in many regions of the world grouper (Epinephelidae) populations are at risk and/or declining steadily, such as in Indonesia. The aim of this study was to determine grouper stock sizes in Karimunjawa National Park, Indonesia. If the establishment of the park with no-take zones was effective in protecting grouper populations, the biomass of the grouper populations in this park should have increased or at least have been maintained between 2005 and 2012… 


Groupers are member of family Serranidae that plays important role in ecology of coral reefs ecosystem as top level predators.Economically, groupers are targets species for their high economic

Potential and Risk of Grouper (Epinephelus spp., Epinephelidae) Stock Enhancement in Indonesia

It was found that the greatest peril for the released grouper of 10 cm length was falling immediately prey to predators in the reef habitat, even though enough hides were available at the release site, since groupers of this particular size class were not trained to survive under field conditions, and requires future adjustment of the official recommendations in use.

The economic performance of grouper (Serranidae) and snapper (Lutjanidae) fisheries in Saleh Bay, Indonesia

The legal basis of the management of grouper and snapper fisheries in Saleh Bay is the Governor Regulation of West Nusa Tenggara No. 32 of 2018. This study adopted a Data Envelopment Analysis (DEA)

The performance of stock indicators of grouper (Serranidae) and snapper (Lutjanidae) fisheries in Saleh Bay, Indonesia

Continuous overexploitation is the biggest problem presently facing small-scale fisheries in Saleh Bay, Indonesia. To further address the fish population decline in this area, the Provincial


Coral reefs has an important function of reef fish. Several symptoms of reef overfishing have been observed in the Spelman Strait coastal waters and they include decreasing live coral cover and

Reef fish in Spelman strait, Indonesia, is one of the fishery resources of considerable economic value. Unfortunately, there is still the use of unfriendly resources equipment (destructive fishing)

Fishing restrictions and remoteness deliver conservation outcomes for Indonesia's coral reef fisheries

Coral reef fisheries depend on reef fish biomass to support ecosystem functioning and sustainable fisheries. Here, we evaluated coral reefs across 4,000 km of the Indonesian archipelago to reveal a

Using ecosystem approach indicators for assessing the ecological status of reef fisheries management in a marine protected area

The results indicated that the ecological status of reef fisheries management of KNP is at a moderate level with an achievement value of 62.75% and the three indicators that need to be improved quickly are fish abundance, fishing gear modification, and fishing capacity.



Changes in reef fish biomass in Karimunjawa NationalPark: a test of the effectiveness of government gazettedmarine parks in Indonesia

In June 2005, following extensive community consultation, national legislation was enacted to change the boundaries of zones that regulate fishing and other resource use in Karimunjawa Marine

Weak Compliance Undermines the Success of No-Take Zones in a Large Government-Controlled Marine Protected Area

Assessment of levels of compliance following the 2005 rezoning of the government-controlled Karimunjawa National Park, Indonesia found apparent willingness of the KNP communities to comply with gear restrictions, but not spatial restrictions is difficult to explain and highlights the complexities of the social and economic dynamics that influence the ecological success of marine protected areas.

Applying local knowledge and science to the management of grouper aggregation sites in Melanesia

In 2003 The Nature Conservancy (TNC) commenced a project titled “Protecting Coral Reefs from Destructive Fishing Practices: Protecting and Managing Reef Fish Spawning Aggregations in the Pacific”.

The ecology of Indo-Pacific grouper (Serranidae) species and the effects of a small scale no take area on grouper assemblage, abundance and size frequency distribution

The present study found that a small scale NTA of 500 m length was large enough to increase the population of top predatory fish and in conjunction with other socially acceptable small scale NTAs it could help maintain and increase important fish stocks over a larger area.
