Abstract

Seagrass beds are found along the shore of Tanjung Merah (North Sulawesi, Indonesia). This ecosystem covers approximately 20 hectars, and are well known to support local fisheries. Thalassiahemprichii was the dominant seagrass species at the study site. This study in the given area was aimed to monitor any changes in fish assemblage structure, and examine the function of seagrass beds for marine fish. Fishes were sampled using the small beam trawl in March 2003, April 2004 and September 2005. A total of 137 species belonging to 34 families were identified. Twenty four species were found abundantly in terms of individual numbers, however Apogon margaritophorus and A. hartzfeldii were the most dominant. These two species were permanent resident, indicated by a catch of large number in different stages of life cycle. We also noticed that many adults of A. margaritophorus kept fertilized eggs in their mouths. This evidence also confirmed that seagrass beds function as both spawning and nursery ground for marine fishes. During three years’ monitoring, there was a slightly seasonal variety in fish assemblage structures.

Abstract

An investigation of the upwelling in the Southern Makassar Strait was conducted by LON (Lembaga Oseanologi Nasional) as part of its research program in ecology and oceanography of the Indonesian waters. It consists of observation on one monitoring station and two oceanographical cruises in the region. The result of the monitoring station indicates clearly the occurrence of upwelling and its effect on the hydrology of the region. During the southeast monsoon the upwelled water causes a decrease in temperature and dissolved oxygen and an increase in salinity, density and nitrate-nitrogen, particularly seen at the lower boundary of the homogeneous layer. During the northwest monsoon the upwelled water is replaced by the Jawa Sea water with high temperature, low oxygen, low salinity, low density, very high phosphate, and high silicate. The observation on the oceanographical cruises reveals the precence of two other types of surface waters in the region. They are the East Kalimantan Coastal Water and the South Sulawesi Coastal Water, each is formed by mixing process of sea water and land drainage along the coast of the two islands respectively. Originally they are characterized by low salinity, low oxygen, high temperature, high phosphate, low nitrate and high silicate. Their salinity and dissolved oxygen increase due to mixing with the upwelled water and the high activity of phytoplankton respectively.

Abstract

This article provides a comprehensive review of the contamination by Butyltin compounds (BTs) and its possible implications on the marine and coastal environments of the Philippines. Butyltin compounds were detected in mussels from all the sampling locations investigated as part of the monitoring surveys under the Asia-Pacific Mussel Watch (APMW) Program conducted in the late 1990s. BTs were detected in green mussels collected from all the aquaculture sites in the country, suggestive of considerable widespread pollution by BTs in the coastal waters. Among BTs, TBT was detected at all locations at relatively higher concentrations, whereas the concentrations of DBT and MBT were lower. This could be indicative that green mussels have limited ability of metabolize TBT to DBT and MBT. In addition, this result may be suggestive of fresh TBT inputs into the aquatic environments and the presence of recent sources along the coastal waters. Concentrations of 0 BT in green mussels were reported up to 790 ng/g wet weight in a site where intensive maritime activities are occurring. Mussels from rural areas contained TBT at lower proportions indicating that TBT usage as antifouling agents is minimal. Tolerable average residue level (TARL) for seafood in the Philippines was estimated at 173 ng/g wet weight for an average person weighing 60kg. Concentrations of TBT or the sum of TBT and DBT in some green mussels analysed revealed that some values exceeded TARL level, which could suggest that humans consuming this seafood from areas with high BTs contamination could be at risk from elevated exposure to BTs. Similarly, BTs were detected in all the skipjack tuna collected, suggestive of the widespread contamination even in offshore waters and open seas on a global scale. Skipjack tuna collected from the offshore waters of the Philippines revealed considerable levels (up to 220 ng/g wet weight), with high percentages of BTs in total tin (0Sn: inorganic tin + organic tin) in the liver tissues. This finding seems to suggest that the anthropogenic BTs represent the major source of Sn accumulation in skipjack tuna. On the other hand, relatively low concentrations of BTs were found in the liver of cetaceans from the coastal waters of the Philippines, which ranged 42-98 ng/g wet weight. Significantly lower hepatic BT concentrations in cetaceans in tropical waters were noted compared with those inhabiting temperate waters proximal to developed nations. This result could imply smaller usage of BTs in the Philippines at least at the present.

Abstract

Eight specimens of Meganthias kingyo were collected from Bitung, North Sulawesi, Indonesia between 2008 - 2010. The specimens were caught from about 70-150 m off Lembeh Island. M. kingyo differs from M. natalensis by having the following characteristics: pores lateral line scales (43 vs. 49); pectoral rays (16 vs. ii.14); body depth (47.1 vs. 51.9); head length (31.0 vs. 38.2), body depth (47.1 vs. 52.9), caudal peduncle depth (12.1 vs. 14.2), pectoral fin length (28.0 vs. 34.3), pelvic fin length (33.6 vs. 31.1), anal fin base length (19.4 vs. 22.2), caudal fin length (66.9 vs. 35.3) and longest dorsal fin ray (48.5 vs. 27.4). Previously, this species has been reported from Houzan-sone, off Miyako and Yaeyama Islands in Okinawa, Japan; and herein is recorded from off Lembeh Island, North Sulawesi, Indonesia.

Abstract

This paper gave evidence of the occurrence of Thamnaconus modestoides in Indonesian waters. A specimen (271.15 mm SL) was collected from the Winenet fish market at Bitung, North Sulawesi in March 2008. It was reported being caught in the depth of 20-30 m, in association with other coral-reef fishes, despite the fact that member of Thamnaconus has been known as deep water species. The morphological features of this new record species were discussed and illustrated.

Abstract

Sea cucumbers belonged to the species of Holothuria atra are one of the holothurians that could reproduce asexually through fission particularly when their ambient environments are not optimum to reproduce sexually. The reproductive pattern of H. atra has been shown to correlate with to the condition of H. atra population as well as their habitats and environments. This study aims to investigate the asexual reproduction and fission rate of H. atra in Tanjung, North Lombok, Indonesia. We conducted surveys in February, May, July, August, September and December 2016 by applying the free collection method. A total of 1,383 individual H. atra were collected consisting of 931 intact or normal individuals, 174 anterior individuals, 261 posterior individuals and 17 uncategorized individuals. Fissioned H. atra were found in every sampling conducted in the six different months with fission rates range from 5.53 to 30.40%. This research shows that the population of H. atra in Tanjung, North Lombok, are susceptible to asexual reproduction (fission). Fission rate value of > 5% is associated with an adaptation mechanism of H. atra to maintain their population in the wild. Further investigation on the environmental conditions stimulating H. atra fission is needed to understand the reproduction and population dynamic of this species in Tanjung waters.

Abstract

In March 1974 a survey was made of the coral reefs of NW Sabah centered on three main areas (1) Kota Kinabalu, (2) Kudat and (3) Labuan. At various sites within these areas, the coral reefs were assessed according to the extent of living coral, the damage resulting from fish blasting, mining and sedimentation, and the accessibility for tourism.The coral reefs in this region support a significant fishery accounting for about 30 percent of the fish landings both in weight and monetary value. Reef fish are caught by lines, gill nets, and illegal use of explosives. The latter method has seriously damaged a number of reef habitats resulting in a marked drop in the fauna including valuable fish and invertebrates.Coral mining for limestone used for foundations of buildings and roads has been carried out on accessible reefs near Labuan and Kota Kinabalu. The removal of coral heads has resulted in extensive reef damage especially near Labuan.Recent efforts have been made to preserve these reefs and has led to the establishment of a national park around Pulau.Gaya. However, a number of other areas require protection both to safeguard the fishery and promote tourism.

Abstract

The investigation of sea surface chlorophyll-a (SSC) and sea surface temperature (SST) in relation to fish catch variability within the Indonesian region were conducted by using satellite data of NOAA-AVHRR, SeaWiFs and Aqua MODIS. The investigation focused in the region of the coastal area of Java, Lampung Bay and South Kalimantan as representation of the environment diversities of the Indonesian seas.  The result shows that seasonal variation in fish productivity has a strong correlation with SSC variability. High fish productivity corresponded well with high concentration of SSC, and the productivity tended to decrease when the SSC concentration was declined. High SSC variability in the coastal area of Java and Lampung Bay was governed by the upwelling  that induced high nutrient load into the sea surface during the southeast monsoon, while  in the northern coastal area of Java and South Kalimantan, it was governed by high precipitation ocurring during the northwest monsoon that enhanced the nutrient load through the rivers and coastal discharge.
