Abstract

Distribution and composition of Indonesian Chaetodontid species may vary among different locations. However, illegal fishing practices such as bombing and poisoning on reef ecosystems have significant contribution to environmental degradation and can change the community structure of fish especially that of Chatodontids that act as indicator species in in the given areas. Therefore, it is important to do periodic surveys to know the current condition and their changing. A study on community structure of Chaetodontidae has been conducted from July toAugust 2011 on coral reef ecosystems of the Banda Sea and its adjacent waters including Banggai, Kendari, and Lamalera Islands. Scuba equipment was used and underwater visual census method was applied for collecting the data at 21 stations. A total of 1399 individual Chaetodontid fishes was observed, belonging to thirty species and seven genera, i.e. Chaetodon (20 species), Heniochus (4 species), Forcipiger (2 species), Chelmon (1 species), Coradion (1 species), Hemitaurichthys (1 species), and Parachaetodon (1 species). Chaetodon kleinii was the most dominant species in the Banggai (74,38%) and Lamalera (71,71%). Kendari was characterized by the presence of C. octofasciatus that contributed 55,20%. There were two dominant groups of Chaetodontidae based on the feeding guild. Facultative coral feeder was the most abundance in Banggai and Lamalera, while the most commonChaetodontidae in Kendari belonged to obligate coral feeder. Chaetodontid diversity in Banggai was the lowest compared to that of in other studied areas. Anthropogenic pressure may become a major factor causing the low diversity and studied species richness in the coral reef ecosystem of Banggai waters.

Abstract

Banggai waters, located in Central Sulawesi Province, is part of the worldâ??s coral triangle area which is wellâ??known to have the highest diversity on stony corals (Scleractinia). A research on stony corals has been carried out at 9 study sites between Juneâ??July 2011, practicing line transect methods and free collection in order to determine the recent condition and diversity of the given coral group. The average of live corals coverage was recorded at 46%(ranging between 24â??77%), and categorized as fair condition. The number of coral species found was 194, distributed in 54 genera. The Banggai waters condition was considered good and potential to sustain the coralsâ??growth. Even though so, in several particular areas, there were still threats on coral reefs.

Abstract

Analysis of air-sea temperatures and sensible heat flux was conducted to investigate heat transfer process on the atmospheric-oceanic boundary for the outer Ambon Bay. The analysis used SST data derived from both satellite product and in situ measurement using linear regression method, as well as meteorological data such as air temperature and wind speed during daytime. The goals of the current work were to evaluate the relationship between SST and air temperature in the outer Ambon Bay, and to investigate the variation of sensible heat flux in association with seasonal variability of the bay. The major findings were: 1) SST was predominantly lower than airtemperature, resulting in the dominance of negative feedback process on the atmospheric-oceanic boundary layer of the bay; 2) the seasonal SST variability was influenced by land heating and upwelling in the Banda Sea; 3) land heating resulted in large gradient of air-sea temperatures, whereas cooler upwelled waters exerted an opposite effect.

Abstract

In Indonesia, Pyrodinium bahamense var. compressum was first recorded in Kao Bay in 1994. In 1996 the illness of more than 30 people and the death of 3 children after consuming shellfish from Ambon Bay was reported. Until the shellfish poisoning cases was reported, occurrences and blooms of P. bahamense, neither its toxic events had never been known in Ambon Bay. It has generated monitoring on the species occurrence which has been carried out since 2008. The bloom of P. bahamense was detected in July 2012. During the bloom event, concentrationsof phosphate, nitrate and dissolved oxygen were measured. Vertical profiles of temperature, salinity, turbidity and chlorophyll a were also measured during the red tide. Cells of P. bahamense, the PSP responsible species, were recorded abundant up to 2,496 cells/ml when red-brown water discoloration was observed in Ambon Bay. After the toxic red tide, human illness of 7 people due to shellfish consumption was also reported. In addition, the bloom event has damaged aquaculture products, due to mass mortality of cultured fish in inner Ambon Bay.

Abstract

In west central Philippines, the monitoring of aquatic systems traditionally focused on dissolved oxygen values and biological oxygen demand, e.g. monitoring by the Environmental Monitoring Bureau around Panay Island. However, single or two factors are considered to be insufficient to assess habitat health precisely. In this paper, we investigated a benthic community and xamined their implications to habitat health of the Iloilo River. According to a prior benthic survey, warning signs pertaining to biotic, abiotic and community factors have been detected. The disturbed onditions in Iloilo River can be attributed to 3 factors; 1) its inherent topography, where bends serve as sinks for materials; 2) the lack of vigorous water exchange that promotes deposition and hinders complete flushing; and 3) the manner of utilization of the river by the local people. We thus concluded that: 1) monitoring for water parameters only is not enough to get a clear picture of habitat health; and 2) proposed that biotic components should be included for monitoring aquatic system.

Abstract

A list of marine isopods recorded from Indonesia has been compiled from the literature published between 1857 and 2012 as well as from Museum Zoologicum Bogorienseâ??s collections and current expeditions. To date, 225 marine species from 97 genera and 19 families have been recorded from Indonesia with two parasitic families Cymothoidae and Bopyridae showing the largest number of species: 63 and 41, respectively. As for the sampling sites, waters surrounding Java, Maluku and Sulawesi have been investigated most intensively with 55, 51, and 40records, respectively. The most comprehensive publication of marine isopods in Indonesia has been that by Nierstrasz (1931). In terms of role as bioindicators, Sphaeroma and Dynamenella have been discovered to survive in polluted waters in Jakarta Bay, suggesting their potential use as bioindicators of water pollution. Future research on basic taxonomy of isopods in Indonesia as well as their ecological functions are recommended.
