This paper used the case study of the Wakatobi Marine National Park, Indonesia to examine changes in the diversity, density and maturity of grouper species over a 5-year period following the establishment of a small-scale no-take area (NTA). This work was carried out to investigate whether “small” NTAs could be effective management strategies over a time scale that is relevant to local fishery communities and their perception of management success. Our research also documents the ecology of… 
Species diversity and some aspects of reproductive biology and life history of groupers (Pisces: Serranidae: Epinephelinae) off the central eastern coast of India
The present paper incorporates data on species diversity and length groups represented in the catches, results of length-weight relationship studies, length at first maturity, and fecundity of grouper species belonging to two genera that are represented inThe North Andhra region, central east coast of India.
Response of Rocky Reef Top Predators (Serranidae: Epinephelinae) in and Around Marine Protected Areas in the Western Mediterranean Sea
It is suggested that biomass gradients could only occur where groupers attain sufficient abundance inside MPA limits, indicating a strongly density-dependent process.
Linking Protection with the Distribution of Grouper and Habitat Quality in Seychelles
The results of this study indicate that while the MPAs in this study are likely too small to benefit large groupers, the improvements to habitat quality have indirect benefits to grouping, especially at their earlier life stages.
Effects of a marine fishery reserve and habitat characteristics in the abundance and demography of the red hind grouper, Epinephelus guttatus
The overriding factor accounting for differences in red hind grouper density among sites appears to be habitat choice, not the protection from fishing conferred by the reserve, according to the analysis of capture-markrecapture methodology.
The Diversity of Grouper ( Epinephelinae ) in Ambon Island , Maluku , Indonesia
Located in the heart of world’s coral triangle, Maluku seas were estimated to harbor around 1,500 species of fish, which make Maluku seas one of the highest in fish diversity. However, the data to
The diversity species variation during five months of observation was affected by the differences in catches area, the condition of aquatic enviroment, and oceanographic con d ition.
Temporal and spatial trends in size, biomass and abundance of groupers (Epinephelinae) in Mafia Island Marine Park: fishers’ perceptions and underwater visual census surveys
Fishers’ perceptions of changes in grouper size and abundance were compared with scientific data collected via underwater visual censuses (UVCs) before (1995) and after (2006 and 2011) the
Demographic and reproductive characteristics of the squaretail coralgrouper (Plectropomus areolatus) in Solomon Islands
The findings of this research demonstrate that P. areolatus, an economically important species in Solomon Islands, is particularly vulnerable to overfishing due to its predicable aggregating behaviour.
The Nassau grouper, Epinephelus striatus, was once an important commercial fish species in the Caribbean, but is now considered commercially extinct throughout its range. Protection measures have


Groupers (Pisces: Serranidae) in fished and protected areas of the Florida Keys, Bahamas and northern Caribbean
Groupers (Pisces: Serranidae) of littoral environments of warm-temperate and tropical regions have expenenced intense fishery exploitation. Indicators of intense fishing include declines or change in

The observed pattern of segregation might be the result of competitive or noncompetitive interactions or of phylogenetic constraints, but the exact mechanism or combination thereof remains unknown.

A case study of the pilot investigations carried out to achieve accurate, precise and efficient sampling strategies for three species of butterflyfish Chaetodon rainfordi, C. plebeius and Chelmon rostratus, at One Tree Reef, is presented.
Influence of habitat on grouper abundance in the Florida Keys, U.S.A.
Habitat was one of several important factors influencing the distribution of groupers among coral reefs types in the Florida Keys and the densities of red and black grouper were correlated significantly with either physical or biotic habitat parameters.
Assessing the impact of removing reserve status on the Abore Reef fish assemblage in New Caledonia
We propose a statistical approach based on multivariate analysis and general linear models to test the consequences of removal of reserve status from the Abore Reef fish assemblage of the Abore Reef

Spawning aggregations of the Nassau grouper, Epinephelus striatus, occurring at the southern end of Long Island were investigated during the winters of 1987–1988 and 1988–1989 and two color patterns were important in courtship and spawning.
Marine Reserves: Rates and Patterns of Recovery and Decline of Large Predatory Fish
Empirical evidence is presented derived from the visual monitoring of density and biomass of large predatory coral reef fish in two small marine reserves and at two control sites in the Philippines from 1983 to 1993 to show the effects of marine reserve protection and fishing.
Movement in a large predatory fish: coral trout, Plectropomus leopardus (Pisces: Serranidae), on Heron Reef, Australia
Abstract. Movement by the larger more mobile species of coral reef fish plays a significant role in determining patterns in abundance and population structure. Fish movement is also relevant to the
Estimating total abundance of a large temperate-reef fish using visual strip-transects
The data suggest that reserve status is causal in these differing abundance and size structure estimates for the large, common, reef fish Cheilodactylus spectabilis (Hutton).
