Abstract

The partial toxicity tests of copper (Cu2+), zinc (Zn2+) and cyanide (CN-) for young cobia (Rachycentron canadum) fishes 45 days-old were conducted in Doson station during ten days (yr 2005). These three toxic substances affected strongly the growth rate of the Cobia fish (length and weight of the body), even at the lowest treated concentration. The LC50 values of copper, zinc and cyanide were 0.32 mg l-1; over mg l-1 and 0,049 mg l-1, respectively. Based on the statistical analysis of growth rate of cobia by determining 1C25, IC50, NOEC and LOEC values, we have addressed the safe concentrations of these two heavy metals and cyanide in the environmental aquaculture which must be lower than 0.025 mg Cu l-1, 0.5 mg Zn l-1 and 0.005 mg CN l-1, respectively. The result also showed that cyanide was the most toxic to Cobia, followed by copper and zinc.

Abstract

A formulation approach to quantify the abundance of coral genera is considered important to obtain basic information necessary in determining the potency and condition of coral, and one application can also be used to set quota for coral trade. The line intercept method has been used in five different area throughout Indonesian archipelago representing prestine area to heavy disturbances. Based on the number of occurrence, the genera dominance, the size of colony and the coral coverage in each study area was assigned scale, weight and value. The calculation gave the range of Total Value (TV) from 5 -20 and the assignment abundance category of coral genera is 17-20 very common, 14-16 common, 11-13 uncommon, 8 -10 rare, and 5-7 very rare. The categorization of each coral genus of certain area can be used to consider whether it can be harvested or not. Suggestion based on this study as follow: coral genera categorized as "very common" can be harvest, coral genera categorized as "common" can be harvest with caution, coral genera categorized as "uncommon", harvest are limited, coral genera as "rare", harvest are strictly limited and coral genera as "very rare" are prohibited to harvest.

Abstract

Molecular biological techniques support the identification of microalgae of Vietnam. Prorocentrum, Alexandrium and Pseudo-nitzschia are main harmful and toxic microalgal genera found in Vietnam coastal waters. The results of morphology and nucleotide sequence analysis of 18S rDNA and ITS 1-5.8S-ITS2 gene obtained from genomic DNA have shown that the Prorocentrum sp. 3 (isolated from Cat Ba, Hai Phong on October, 2004), Alexandrium sp. 5 (collected on October, 2004) and Pseudo-nitzschia sp. G3 (colleted in Do Son, Hai Phong on December, 2005) belonging to Prorocentrum mexicanum (the homological percent of 99.9% with sequencing of P mexicanum in Genbank ofY16232, AY886763), A. minutum (99.8% - AJ535388, DQ168664) and Pseudo-nitzschia pungens (98.8% - AY544769, DQ166533), respectively. The obtained results indicated that the exceptional fresh samples, for Prorocentrum genus which may be preserved at 25% ethanol, 4% formaldehyde, 1% glutaraldehyde, while Alexandrium genus ó at 25% ethanol, and Pseudo-nitzschia genus - 4% formaldehyde and 1% glutaraldehyde for two weeks have not effected on their analysis of sequences generated by Single Cell PCR method. In these studied samples, the nucleotide sequences obtained from genomic DNA and Single-cell PCR methods were the same with the homological percent more than 99%. Application of this method to samples collected from Phu Quoc Island, southern part of Vietnam, in 27-29, June, 2006 showed that Prorocentrum mican and P sigmoisdes were found.

Abstract

Surveys of the flora and fauna of the Cairns tidal wetlands were carried out by members of the Australian Littoral Society during the summers of 1974 and 1975. These wetlands cover an area of 6000 hectares in Trinity Inlet and the Barron River delta. The Cairns mangrove and saltmarsh vegetation forms distinct patterns of zonation which appear to be largely controlled by the volume and constancy of freshwater flow. The results of extensive collections revealed a wetlands associated fauna of invertebrates and fish that is considerably more diverse than has previously been reported for northern Queensland. While some species are ubiquitous, many of the invertebrates have been found only in a discrete habitat within particular zones of vegetation. Species diversity of molluscs and crustaceans is greatest in the most constantly inundated zones. A diverse fauna occurs in rotted mangrove logs. Data were obtained on the export of organic material from a small mangrove watershed on one day in December 1975. These revealed a figure for detritus of 11.3 gC/m2/day. This was composed of a dissolved organic carbon fraction of 6.3 gC/m2/day, and 5.0 gC/m2/day of particulate organic carbon. These figures are discussed in relation to available literature on mangrove forests and estuaries. Rapid urban and agricultural development of Cairns is now placing a large portion of these wetlands under serious threat of destruction. The prospects for the future conservation of the Cairns tidal wetlands are discussed.

Abstract

There are strong indicators that the degradation of coral reefs may increase the intensity and frequency of ciguatera fish poisoning (CFP) outbreaks when denuded reef surfaces are colonised by macro algae that are the preferred hosts of toxic dinoflagellates that can cause the disease. Ciguatera field studies have concentrated on the dinoflagellate genus Gambierdiscus, well known to be the producer of ciguatoxin precursors. Moreover the potential of toxins from other dinoflagellate genera such as Prorocentrum and Ostreopsis is less often considered. Whilstit is known that toxic compounds produced by Ostreopsis species include ostreotoxins (OTX) and ostreocins, the potential harmful impacts of Ostreopsis, Prorocentrum and Gambierdiscus species on coral reef organisms (and ecological impacts) are largely unknown. In addition, CFP has historically largely occurred on the oceanic islands of the world’s tropical seas, but has only recently been reported in the major archipelagoes of Indonesia and thePhilippines. In view of their degraded coral reef ecosystems and the potential link between reef health and CFP, this study examined three sites in Bali and Gili Trawangan over one year, to assess the prevalence and distribution of CFP related dinoflagellate species. Beside finding Gambierdiscus, Ostreopsis and Prorocentrum at most sites, water column nitrogen nutrient levels were also found on the average to be 3−4 times higher than that recommended for a healthy coral reef (0.013mg/L). However the maximum abundance of Prorocentrum, Ostreopsis and Gambierdiscus found were low (103, 2,860 and 28 cells per gram of wet weight of host macroalgae, respectively). A factor thatmay play a part in the potential for toxicity at these sites is the abundance of sea grass (and associated micro flora and fauna) which are often present within and adjacent to coral reef ecosystems across the Indonesian archipelago.

Abstract

Paguridea in the Indo-Pacific have 10 harpacticoid copepod associates: 3 Sunaristes, 3 Brianola, 1 Porcellidium, and 3 Paraidya. Four of these copepods are reported from hermit crabs in the Moluccas: Sunaristes tranteri Hamond, 1973, from Dardanus guttatus, Dardanus lagopodes, Calcinus latens, Calcinus minutus, Calcinus gaimardi, Calcinus sp., and Trizopagurus strigatus; Porcellidium brevicaudatum Thompson and A. Scott, 1903, from Dardanus guttatus, Dardanus lagopodes, Dardanus megistos, Calcinus latens, Calcinus minutus and Trizopagurus strigatus; Paraidya minor Sewell, 1940, and Paraidya major Sewell, 1940, from Dardanus guttatus, Dardanus lagopodes, and Dardanus megistos.

Abstract

Sediment of 16 sites in the Kelabat Bay were monitored for metal contamination and toxicity in 2006. Two patterns of metal contaminants distribution in the sediment were observed. Higher concentrations of lead and copper were found in March than those in July, and so was in the inner bay than those observed in the outer bay, while different pattern was observed for cadmium concentration. The highest lead concentrations were observed at site 7 (inner bay) both in March and July. Although elevated levels of cadmium, lead and copper were observed in sediments, they were still in the tolerable level for marine life. Sediment of the bay was also evaluated for its toxicity using marine phytoplankton, Chaetoceros gracilis and sea urchin, Tripneustes gratila. Results of the tests reveal that no toxic effects of sediment to the growth of phytoplankton were observed, but to sea urchin fertilization of the sediment may have toxic effect.

Abstract

Wakatobi Regency has a huge capacity in natural resources with its beautiful and pristine coastal ecosystems that host 25 coral reefs species in diverse forms. The regency is considered as the world’s best biosphere and frequently visited by local and international tourists for diving/snorkeling. The objectives of this study are to determine the role of marine tourism in Wakatobi’seconomy and formulate an appropriate and strategic policy for its marine tourism development plan. Methods used in this research are theLocation Quotient (LQ) analysis to determine the relative ability of a sub-area to a wider area in the specific sector, and theProspective Participatory Analysis for preparing the marine tourism development plan. The LQ analysis for the marine tourism (trade, hotels, and restaurants) sector based on GDP data from 2004-2007 shows values ranging from 0.808-0.881, which indicate poor potential and low contribution of this sector toWakatobi’s economy. TheProspective Participatory Analysis involving 18 variables related to marine tourism development indicates that Wakatobi Regency has four key variables. These are:community behavior towards environmental protection, community character, human resources andmotivation. These variables would play an important role in preparing and implementing marine tourism development plan in Wakatobi Regency.
