Abstract

Groupers (Family Serranidae) are well known as top predators in the coral reef ecosystem. This family is one of the most important ecological organisms in the food web at Raja Ampat reefs. The aim of this study, therefore, was to investigate the food composition as well as the inter and intra-specific competition of two Serranidae species, including Epinephelus malabaricus and Epinephelus areolatus in Waisai, Raja Ampat. This study is expected to fill gaps on groupers food preferences. A total sample were collected at the fish landing site was 6 fish (2 sample of Epinephelus areolatus and 4 sample of Epinephelus malabacrius). DNA Amplification was performed using the COI mithocondrial gene marker (HCOI12198 and LCOI1490 primers). Bioinformatics and data analysis using QIIME 2 and R Software. This further comprised of α and β diversities. The results showed that Serranidae diet composition comprise of 13 species. Epinephelus malabaricus species demonstrated more diet composition varieties than Epinephelus areolatus. The most abundant diet found in all fishes’ gut samples was come from Scianidae family. The results indicate that there is an absence of any interspecific competition between the two species studied, due to a wide variation of diet composition. Conversely, intraspesific competitions existed amongst the Epinephelus malabaricus niches. This study highlighted DNA Metabarcoding application in trophic level and food web studies, as well as facilitating the development of information for ecological references.

Abstract. Pratiwi NTM, Imran Z, Ayu IP, Iswantari A, Wulandari DY. 2020. The phosphorus load and the variation of the trophic states of Cirata Reservoir (West Java, Indonesia) from 1988 to 2017. Biodiversitas 21: 4176-4183. Cirata Reservoir was constructed in 1987 between Saguling and Jatiluhur Reservoirs; these are the three man-made cascading lakes in West Java, Indonesia. Cirata Reservoir has been used for floating cage aquaculture activities. The high organic content from the remains of the fish pellets raised the phosphorus (P) load, resulting in the eutrophication of the reservoirs. This research was aimed to assess the P load and the variation of the trophic states of the reservoir from year 1988 to 2017. The trophic states and the nutrients’ conditions of the water were determined using Myxophycean Index. Four groups of phytoplankton were found in the reservoir during observation: Cyanophyceae, Chlorophyceae, Bacillariophyceae, and Dinophyceae. In addition, one group was found in a smaller number of observations: Eugolenophyceae. Although the community structure of the phytoplankton has changed, the Cyanophyceae was always dominant in response against the condition of nutrients, especially P. The P load is closely related to the number of floating cages in the reservoir. This evidence showed that Cirata Reservoir tended to be relatively eutrophic. In general, despite that the P load tended to fluctuate, the trophic states of Cirata Reservoir remained dynamic in relatively high conditions; showed by the oligo-mesotrophic state during its first year of operation, then increased to eutrophic and hypertrophic by the next decade. Although the P load tended to decrease, it remains in the eutrophic condition in the recent time.

Abstract

Coral reef ecosystems are centers of biodiversity with high productivity in tropical waters; however, information on reef fish communities and their behavioral interactions with coral colonies in the Seribu Islands remains limited. This study aimed to identify reef fish species, coral genera utilized by reef fishes, and variations in reef fish behavior associated with coral colony structures. An Underwater Video Survey (UVS) was conducted using systematic underwater video recordings at Panjang, Pelangi, Belanda, and Kelapa Islands, Jakarta, Indonesia. The Videos were analysed to identify reef fish species, coral genera, and behavioural patterns associated with coral colonies. A total of 215 reef fish species belonging to 82 genera and 29 families were identified across the study sites. Kelapa Island exhibited the highest species richness (120 species), followed by Belanda Island (119 species) and Panjang Island (107 species), while Pelangi Island showed the lowest richness (83 species). Sixteen coral genera were recorded, with Acropora and Porites being the most dominant and occurring at all study sites. In contrast, Cyhastrea, Echinophyllia, Echinopora, Monstastraea, Platygra, and Pocillopora were restricted to a single location. Acropora and Porites also supported the highest numbers of associated reef fish species. A total of 13 behavioural categories were observed. Feeding, roaming, and hovering were the dominant behaviours across all study sites, whereas cleaning, resting, ambush, and aggressive behaviours were less frequent. Variations in behavioural patterns among islands suggest that complexity influences both reef fish diversity and behavioural expression. These findings highlight the importance of structurally complex coral habitats in supporting reef fish diversity and ecological functions in the Seribu Islands.
