Scientific Survey

A 573 species-long checklist of the fishes in this 50 km2 tropical marine park was created predominantly by combining an unpublished scientific survey from 1992 with a hobbyist’s large photograph collection from between 2006 and 2009. Of the Indo-Pacific region’s coral reef-associated fish species, 15.2% are found here. Drawn from 83 families, the most speciose are Pomacentridae (71), Gobiidae (68) and Lab-ridae (55). A regression formula using the Coral reef Fish Diversity Index (CFDI) for species seen in 1992 suggests the park hosts 464 species, compared with the CFDI-based estimate of 495 based only on da-ta collected between 2006 and 2009, and 596 for the combined Index. With only 62% of the Index’s species seen both in the earlier and later lists, the utility of the CFDI is questionable at a site or over a time-span like this.

Reef Health

The components of coral reef ecosystem can be described by the unique regulation in community level. Coral reef fishes use coral reef as their habitat and they highly depend on coral reef health. Otherwise, the condition of coral reef health can be predicted by the biodiversity of coral reef fishes. The research aim was describe communities differences between two explored area in marine tourism spots in Pahawang Island. This research was conducted on November 2019 at two stations on the coral reefs ecosystem of Pahawang Island represented the two quitely different area, the marine tourism and the visitor areas.  The coral reef fishes were observed by using visual census method with a Line Transect length of 30 meters and a visibility of 2.5 meters left and right of the transect.  Coral reef fish community structure was measured by diversity, similarity, and dominancy indexes. A total of 1.940 coral reef fish species from 13 families were recorded. Pomacentridae is the most speciose family (1.091 species), followed by Siganidae (308 species) and Labridae (166 species). Biodiversity of coral reef fishes at Pahawang Island showed results diversity index (H') in both observation stations classified as medium with a low dominance index value (C) and similarity index (E)  at both stations classified as high, presumably as a result of tourism activities. The diversity index at station 2 has a greater value than station 1 as a tourist area with diving and snorkeling tourism activities, at station 2 there are more types or genus of reef fish, compared to station 1.

Abstract One of the most robust metrics for assessing the effectiveness of protected areas is the temporal trend in the abundance of the species they are designed to protect. We surveyed coral-reef fish and living hard coral in and adjacent to a sanctuary zone (SZ: where all forms of fishing are prohibited) in the World Heritage-listed Ningaloo Marine Park during a 10-year period. There were generally more individuals and greater biomass of many fish taxa (especially emperors and parrotfish) in the SZ than the adjacent recreation zone (RZ: where recreational fishing is allowed) — so log response ratios of abundance were usually positive in each year. However, despite this, there was an overall decrease in both SZ and RZ in absolute abundance of some taxa by up to 22% per year, including taxa that are explicitly targeted (emperors) by fishers and taxa that are neither targeted nor frequently captured (most wrasses and butterflyfish). A concomitant decline in the abundance (measured as percentage cover) of living hard coral of 1–7% per year is a plausible explanation for the declining abundance of butterflyfish, but declines in emperors might be more plausibly due to fishing. Our study highlights that information on temporal trends in absolute abundance is needed to assess whether the goals of protected areas are being met: in our study, patterns in absolute abundance across ten years of surveys revealed trends that simple ratios of abundance did not.

Abstract The corallivorous Crown-of-Thorns Starfish (CoTS, Acanthaster spp.) has been linked with the widespread loss of scleractinian coral cover on Indo-Pacific reefs during periodic population outbreaks. Here, we re-examine CoTS consumption by coral reef fish species by using new DNA technologies to detect Pacific Crown-of-Thorns Starfish (Acanthaster cf. solaris) in fish faecal and gut content samples. CoTS DNA was detected in samples from 18 different coral reef fish species collected on reefs at various stages of CoTS outbreaks in the Great Barrier Reef Marine Park, nine of which had not been previously reported to feed on CoTS. A comprehensive set of negative and positive control samples confirmed that our collection, processing and analysis procedures were robust, although food web transfer of CoTS DNA cannot be ruled out for some fish species. Our results, combined with the (i) presence of CoTS spines in some samples, (ii) reported predation on CoTS gametes, larvae and settled individuals, and (iii) known diet information for fish species examined, strongly indicate that direct fish predation on CoTS may well be more common than is currently appreciated. We provide recommendations for specific management approaches to enhance predation on CoTS by coral reef fishes, and to support the mitigation of CoTS outbreaks and reverse declines in hard coral cover.

Species Richness And Abundance

This study aims to determine the distribution and abundance of reef fish in coral reef waters of Sub District Maba and was conducted at 10 stations. Data were collected by conducting visual census on the 50-meter transect line at 5 meters depth. In addition to revealing the number of species and abundance of coral fishes, data were analyzed to determine the diversity index (Shannon-Wiener). Based on field observations, most of the reef fishes  found in the Sub-district of Maba surrounding waters are being categorized to have less potential category (50%);  fair potential (41.67%); potential (8:33%); and  there is no population being classified in very potential category. Several locations have the potential reef fish condition were Jara-jara Cape, Gee Island, and Para-para Island.  Based on the existence of the target species population, in term of species richness and abundance, it is assumed that largely dominated by the target fish species that has low economic value. On the other hand target fish that has high economic value only consists of few species such as grouper, jacks, sweetlips, and snappers.   Keywords : coral fishes,  coral reef, sub district maba ABSTRAK Penelitian ini bertujuan untuk mengetahui distribusi dan kelimpahan ikan karang di perairan terumbu karang Kecamatan Maba. Penelitian dilakukan di 10 lokasi. Pengambilan data dilakukan dengan metode sensus visual pada transek garis sepanjang 50 meter, kedalaman 5 meter. Selain mengungkapkan jumlah spesies dan kelimpahan individu, analisis data diarahkan untuk mengetahui indeks keanekeragaman (Shannon-Wiener).  Berdasarkan hasil pengamatan, sebagian besar sumberdaya ikan karang di wilayah Kecamatan Maba, telah masuk dalam kategori kurang potensial (50 %); cukup potensial (41,67 %); potensial (8.33%); dan tidak ada yang tergolong dalam kategori sangat potensial.  Lokasi-lokasi yang memiliki kondisi ikan karang yang potensial,  Tanjung Jara-jara, Pulau Gee, dan Pulau  Para-para. Keberadaan populasi spesies target, baik kekayaan spesies maupun kelimpahan individu, ternyata sebagian besar didominasi oleh jenis ikan target yang bernilai ekonomi/pasar rendah.  Beberapa jenis ikan yang memiliki nilai ekonimis penting ditemukan  seperti, kerapu, Sweetlips (bibir manis), Bobara, dan kakap.

Resilience Indicators

Infrastructure development in the particular sites of  Seribu Islands as well as those in main land of Jakarta City increased with coastal population this phenomenon is likely to increase the effects to the adjacent coral waters of Seribu Islands.  Chemical pollutants, sedimentation, and domestic wastes are the common impact and threatening, the survival of coral reef ecosystem. Coral reef resiliences naturaly remained on their processes under many influences of supporting factors. One of the major factor is the role of reef fish functional groups on controling algae growth to recolonize coral juveniles. The  aim of this study to obtain data of a herbivory and other fish functional groups of reef fishes in the Pari Islands that are resilience indicators, or that may indicate the effectiveness of management actions. A conventional scientific approach on fish diversity and abundance data gathering was conducted by the underwater visual cencus. Diversity values of the reef fish functional groups, such as the abundance of individual fish including species, were collected and tabulated by classes and weighted as a baseline to understand the resilience of coral reed based on Obura and Grimsditch (2009) techniques. The results succesfully identified several fish functional groups such as harbivores (21 species), carnivores (13 species) and fish indicator (5 species) occurred in the area. Regarding the aspects of fish density and its diversity, especially herbivorous fish functional group, were presumably in the state of rarely available to support the coral reef resiliences. Resilience indices ranged from 1 (low level) to 3 (moderate level) and averages of the quality levels ranged from 227 to 674. These levels were inadequate to support coral reef recolonization.
