Abstract

Two specimens of Odontanthias flagris have been caught from Bitung, North Sulawesi in June 2010. Previously, nown locations of this species are Okinawa and Nishino-shima, Japan. O. flagris is very similar with O. rhodopeplus. They shares following characters: dorsal fin rays X, 13; anal fin rays III, 7; pectorals fin rays 17-18; scales above lateral line 7; scales below lateral line 19 and gill rakers on lower limb 28. Characters differing O. flagris from O. rhodopeplus, O. chrysostictus and other six species appear in the percentage of orbit diameter. In addition, O. flagris has shorter pelvic fin rays but longer caudal peduncle and third dorsal fin spine. Its morphological features, distribution, remarks and photo of species are given in this paper.

Abstract

This study examined the diversity and abundance of zooplankton in Lembeh Strait, North Sulawesi. Plankton were sampled monthly from September 2004 to February 2005, collected at four stations using a plankton net of 300 pm meshsize with vertical tow of 10 m water column from the bottom. Environmental factors i.e pH, salinity, current velocity, and dissolved oxygen (DO) were measured in situ at the time of plankton sampling. In general, the environmental conditions of Lembeh Strait were in optimal range for zooplankton. There was a similar pattern in the abundance of zooplankton among stations. Crustacea (mainly Copepoda) was the dominant genera among stations, followed by Ciliata and Tunicata. In all stations, the most abundance taxa (72.3%) was Crustacea (21 genera), mainly copepod (18 genera). There were 7 other classes of holoplankton: Ciliata (2 genera), Rhisopoda (1 genus), Hidrozoa (1 genus), Polychaeta (2 genera), Sagitoedea (1 genus) and Tunicata (2 genera). Meroplankton (larva) were only represented by 5 genera. The most common genera were calanoid copepods, such as Calanus spp., Undinula spp., Eucalanus spp., Rhincalanus spp., Paracalanus spp., and Acartia spp. Diversity, evenness and dominance indices showed that Serena Island, a relatively uncontaminated area, was more productive than the other three stations which were considered as relatively contaminated area with anthrophogenic sources.

Abstract

Study on estuarine fishes in Mimika district, Papua was carried out at six estuaries from 2000 to 2006, as a part of monitoring program conducted by PT Freeport-Indonesia. This study mainly aimed to document the fish diversity, dominance, abundance and weight. Samples were collected from six estuaries, namely Ajkwa (tailing affected estuary), Tipoeka (disturbed estuary), Minajerwi, Kamora, Mawati and Otakwa (tailings unaffected estuaries). The total fish catches from the study sites during the study were 133 species belonging to 50 families, with the total abundance and wet weight were 85,523 individuals and 1,834 kg, respectively. The indices of diversity and evenness ranged 1.1-2.1 and 0.4-0.8, respectively. Based on the sample abundance, the dominant families consisted of pony fishes (Leiognathidae), drum fishes (Sciaenidae) and anchovies (Engraulidae), catfish (Ariidae) and glassfish (Ambassidae), whereas based on the samples weight, the dominant families comprised of Sciaenidae, Ariidae, Leiognathidae, Engraulidae and Clupeidae. The results show that there were no significantly differences in diver-sities and abundances among the six estuaries of Mimika district.

Abstract

Study on biodiversity and size structure of sharks in the Indian Ocean was conducted at several landing sites and fish markets, i.e. Pelabuhanratu (West Java), Cilacap (Central Java), Kedonganan (Bali) and Tanjung Luar (East Lombok ). Field observation was done from April 2001 to March 2006. The results showed that there were 86 species of sharks belonging to 16 families in the Indian Ocean. The sharks were dominated by family of Carcharhinidae and Squalidae with 24 and 23 species, respectively. A high diversity of sharks was found at Kedonganan-Bali (49 species), at Tanjung Luar (47 species), at Cilacap (32 species) and at Pelabuhanratu (27 species). Size of sharks landed at those landing sites varied in length, the length of Carcharhinus amblyrhynchos was between 90 cm and 170 cm TL, C. sorrah (55-155 cm), C. obscurus (205-295 cm) and P glauca was caught at length between 205-300 cm.

Abstract

In order to characterize the distribution pattern of rotifers Brachionus spp. in North Sulawesi, sample collections have been conducted at four locations, two at east coast and other two at west coast of North Sulawesi peninsula, which are connected to Maluku and Sulawesi Seas, respectively. At each location, a 40 p.m mesh size plankton net with a 0.3 m opening diameter was horizontally towed at three sites to represent coastal water, estuary and brachkiswater pond. Sampling periods were in January and August 2005 to represent west monsoon and east monsoon, respectively. Each sampling was performed twice a day during high and low tide. Some environmental factors were also measured in situ during the sampling. Three species of Brachionus were found during the survey, Brachionus rotundiformis, B. caudatus and B. quadridentatus. Their abundances were significantly different, both between locations and sampling sites. However, among the similar habitat such as between Manembo-nembo and Minanga brachkishwater ponds, B. rotundiforms abundance was not significantly different. This species was the most abundant compared to the other two species, in average 1984,4 ind/m3, while the other species was as low as 26,1 ind/m3 and 212,9 ind/m3 for B. caudatus and B. quadridentatus, respectively. The abundance of rotifers in northern areas connected to Molluccas Sea is higher compared to those in the southern areas connected to Sulawesi Sea. Distribution of B. caudatus is very similar to those of B. rotundiformis, while B. quadridentatus appears to have its specific pattern. Results of this study suggest that the abundance and species composition of the rotifers reflect trophic status of the aquatic ecosystem in the area. It is still awaiting future studies to elaborate the impacts of the trophic gradients in horizontal distribution of rotifers. Therefore, it is necessary to conduct a long term monitoring with emphasis on the structure of rotifer assemblages in a variety of sites subjected to environmental perturbations, including anthropogenic contaminant inputs.

Abstract

The occurrence and distribution of family trochidae at Badi Island, Spermonde Archipelago off SW-Sulawesi has been studied. The line transect with combination of quadrant method was used during sampling. A transect covering 400 m of sampling area was applied at 1, 3,5, and 7 m depth, respectively. Parameters such as shell length and size-class distribution were observed. Ecological parameters were also recorded during investigation. We found the presence of 11 species of trochidae at the study area. It was evident that some trochidae were common and while top shell Trochus niloticus seems to be rare. Vertical distribution among this group was uneven. The number of species decreases with increasing depth. Furthermore, high density of smaller trocha occurred at shallow water followed by a decline with changes in depth.

Abstract

Study on demersal fish in Kupang bay was carried for 6 months, from July 2002 to December 2002. Sampling was conducted twice a month at the ten-selected locations within the bay using different fishing gears such as gill net, bottom logline, hand line and traps. Fishes caught were stored in a icebox and transferred to the laboratory of the Fisheries Faculty of Artha Wacana Christian University, Kupang for further identification. Similarity index of fish species of the study sites was analyzed using non-metric multidimensional scaling (nMDS) of the matrix Bray Curtis similarity. A computer program PRIMER was used to perform the analysis. The result shows that there are 56 species (total catch 890 fishes) found during this study and their similarity index revealed three groups of study sites. Interestingly, it seems that these species remained to have some strong association with the existing ecosystem.

Abstract

This research was part of successive studies on culture techniques of juvenile green snail (Turbo marmoratus). This study was carried out for 14 weeks in coastal waters of Morella, Ambon Island. Three cages were placed at depths of 0 m, 4 m and 8 m below mean sea level. Each cage had a bottom area of 0.81 m2 and was stocked with 20 green snail juveniles of 40-50 mm shell diameter. During the first 4 weeks, juveniles reared at 0 m deep showed lowest instantaneous growth, while those reared at 8 m deep attained highest instantaneous growth. The instantaneous growth decreased significantly over 6 weeks for juveniles reared at 4 m and 8 m deeps. Over 14 weeks, juveniles reared at 8 m deep had higher daily growth than those at 0 m deep. It is recommended that to grow green snail juveniles at 8 m deep without any food complement, the substrates (coral nibbles) in the cages need to be renewed every 4 weeks with ones covered with microalgae.

Abstract

Marine life of Indonesia is very well known as a high diversity according to Ekmans hyphothesis. However, from the larva fish perspectives, this hypothesis seems to be rejected according to the comparative results of larval fish studies during the Snellius Expedition (1984-1985) in Banda Sea and the larval fish observation related to the East Australian Current (1998-1999) off New South Wales coast in Australian waters. Larval fish diversity from some previous studies over the world is also included. Several suggestions are also recommended to enhance our knowledge in marine biodiversity including improvement in marine biodiversity observation such as, research programs, field and laboratory facilities and numbers of taxonomists, and also collaborative works among research institutes, universities, and non-governmental organizations.

Abstract

Seagrass plays important ecological roles and ecosystem services, yet degrading alarmingly in the South China Sea (SCS), one of the largest marginal seas of the Western Pacific. As connectivity is a vital component in population persistence, understanding of connectivity is of importance for effective seagrass conservation management. In the South China Sea, our understanding of connectivity is mainly based on studies in fishes and invertebrates. Connectivity in seagrass populations, on the other hand, is still poorly investigated. In this review, I predict that genetically structured population of seagrass is likely to occur in the SCS. Future research on seagrass connectivity should include (i) investigation on the pattern of connectivity at a local and broader-regional scale, and (ii) investigation on processes involved in the seagrass connectivity. These investigations are aimed to improve our knowledge of seagrass connectivity and to contribute in providing a solid framework for seagrass restoration/transplantation and spatial planning of seagrass management.
