Enhancing reef fish diversity using artificial reef-building: A case study of coral reef rehabilitation on Nyamuk Island, Anambas Islands

Abstract CCMRS-IPB conducted coral reef rehabilitation at damaged coral reefs around Nyamuk Island. Those artificial reef buildings for rehabilitation gave shelter spaces for reef fish. This research aims to calculate the effect of coral reef-building, which enhances rugosity to the reef fish diversity around the rehabilitation sites. The study was conducted on Nyamuk Island in the Anambas Islands. Reef fish were sampled annually from 2014 to 2019 using the underwater visual census. The Diversity index and non-Metric Multidimensional Scaling were built to discover reef fish diversity, and reef fish species were affected the most. Yearly data shows an escalation number of reef fish abundance and richness at the end of 2019. The major reef fish group is found to have constant diversity throughout the year compared to other functional groups. The target reef fish group came to this rehabilitation ecosystem primarily attracted by nourishment availability. There is a shift in the reef fish diversity from the early year to the project end. Generally, major reef fish groups will be refuged first around the rehabilitation sites, especially territorial types. Target fish groups from herbivorous and carnivorous types will mostly come along after their food availability and location to get around.

Reef fish is one benchmark to determine a coral reef ecosystem's biodiversity. Reef fish communities are important in coral reef ecosystems because of their trophic relationships with other biotic components. The aim of this study was to determine the biodiversity of reef fish on Halang Melingkau Island, Kotabaru District, South Kalimantan, Indonesia. This research was conducted in March-August 2019. Coral reef fish data were collected using an underwater visual census method. Transects were applied as close as possible to the substrate using a 50 m roll-up measuring tape. Three transects were applied at each station. A total of 98 reef fish species from 19 families were recorded in this study. The fish community in Halang Melingkau island belongs to the family of Pomacentridae, Labridae, Chaetodontidae, Scaridae, Haemulidae, Lutjanidae, Scolopsidae, Serranidae, Caesionidae, Holocentridae, Siganidae, Pomacanthidae, Apogonidae, Pempheridae, Scorpaenidae, Tetraodontidae, Blenniidae, Platacidae, and Zanclidae. The highest abundance of reef fish was 1.88 ind/m2, and the lowest was 0.14 ind/m2. The dominance index (C) ranged from 0.03 to 0.13, the homogeneity index (E') ranged from 0.72 and 0.94, and the diversity index (H') ranged from 2.17 to 3.53. Water quality data measurements of temperature, brightness, current speed, pH, and DO (Dissolved Oxygen) were within the tolerance limits of water quality standards based on the Minister of Environment Decree No. 51 of 2004, Republic of Indonesia.

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.

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.

Coral reef fish are play key role in coral reef ecosystem. The presence of reef fish affected by antrophogenic and natural factors, such seasonal changes. This study aimed to asess the temporal variation of coral reef fish group in Tidung Kecil Island using eDNA metabarcoding and Undewater Visual Census. This research was conducted at December 2019 (West season) and August 2020 (East season). Target group are dominated in west season (64.1%) and east season (59.25%) using eDNA metabarcoding. While, major group fish are the highest relative abundance in both season by using Underwater Visual Census. Family Carangidae are the highest species richness (15 species) in wet season and Serranidae (3 species) in east season, respectively. Futhermore, famili Pomacentridae are the most richness species in west and east seasons 10 and 11 species respectively. Thus, it can be concluded these two methods are effective for monitoring structure or abundance of coral reef fish based on seasonal variation. Ikan karang menjadi indikator dalam menilai keanekaragaman hayati di ekosistem tersebut. Keberadaan ikan di ekosistem terumbu karang dapat dipengaruhi oleh faktor antropogenik dan faktor alam salah satunya perubahan musim. Penelitian ini bertujuan untuk menganalisis kelimpahan kelompok ikan terumbu karang di Pulau Tidung Kecil menggunakan eDNA metabarkoding dan Sensus Visual. Pengambilan data dilakukan pada bulan Desember 2019 (musim barat) dan Agustus 2020 (musim timur). Ikan target mendominasi pada musim barat dan timur dengan persentase sebesar 64.11% dan 59.25%. Sensus visual berhasil mendeteksi ikan mayor dengan persentase tertinggi 62.5% di musim barat dan 82.8% di musim timur. Famili Carangidae merupakan famili dengan jumlah spesies tertinggi di musim barat (15 species) dan Siganidae di musim timur menggunakan eDNA metabarkoding (3 species). Hasil UVC menunjukkan famili Pomcentridae memilki jumlah spesies tertinggi di kedua musim (11 dan 10 spesies) menggundakan sensus visual. Dapat disimpulkan bahwa kedua metode tersebut dapat menjadi pendekatan dalam monitoring struktur atau kelimpahan ikan terumbu karang berdasarkan musim.

This research was carried out with a survey method during August 2019 with the aim of knowing the biodiversity of target fish and their potential in the coral reef ecosystem in the waters of Maitara Island, North Maluku Province by collecting primary and secondary data in the form of coral reef conditions (lifeform), fish conditions (diversity, uniformity and dominance) as well as environmental parameter data in the form of temperature, salinity, current velocity, and brightness. The collection of data on the condition of coral reefs and fish was carried out simultaneously, namely 1 dive at each station. Visual census method is used for reef fish data. The results of visual observation of reef fish in the waters of Maitara Island found that there were 13 familyes included in the major fish group consisting of 7 familyes, 1 family of indicator fish and 5 target fish groups. The reef fish found at the observation location of station 1 consisted of 59.3% major fish groups, 24.2% target fish and 16.5% indicator fish and at station 2 reef fish consisted of 62.1 major fish groups. %, target fish is 23.8% and indicator fish is 4.1%. Overall, the results of the visual observations of reef fish showed that major fish were the most dominant, found as much as 66.7% of the target fish groups were 23.9% and indicator fish groups were 9.4%. The lack of presence of indicator fish groups shows that the fertility of the coral reef ecosystem in the waters of Maitara Island is no longer in good condition, because the indicator fish group is a type of fish that indicates good and bad parameters of coral reef conditions in the waters.
