Abstract

The study aims to investigating the morphometric and beaks relationships in the Bigfin reef squid, Sepioteuthis lessoniana Lesson 1830. It is shown that fin length and tentacle length linearly correlates with dorsal mantle length. Unlike fin-mantle relation which exhibits no sexual differences, tentacle tends to develop relatively more rapidly in female when mantle attains 70 mm. It is also evident that dorsal mantle length linearly correlates with lower hood length, with slope (b) and intercept (a) of 30.3 and 4.57, respectively. Logarithmic relationship is found between total body weight and lower hood length, with corresponding values of 2.84 and 0.611. Their application for coastal cephalopod biomass estimation from beaks is discussed.

Abstract

Dunaliella salina responds to cadmium present in cells by synthesizing phytochelatin. Reverse Phase (RP)and common HPLC analysis describe the formation of complexes between Cd and γ-glutamyl peptides in cells. The unique peptides chain chelate Cd by thiolate bonds formation. Two classes of Cd-PCn complexes were identified as specific Cd-peptides complexes binding in D. salina.

Abstract

This experiments was conducted as response to the serious negative impact of shrimp aquacultres into the environment. The shrimp-Gracillaria polyculture system was hypothesized to reduce excess pollutant in the shrimp pond. Variation in Gracillaria density was used as treatments. Two important aspects are discussed in this paper, that are the effect on shrimp productivity and efficiency in carbon energy conversion into harvestable products. There were significant evidences that the shrimp-Gracllaria polyculture system increase the sizes, total biomass, survival and growth rate of shrimp. The density of Gracillaria was positively correlated with all of those parameters. The carbon energy conversion was also significantly affected by Gracillaria density. The carbon energy conversion into harvestable products was more efficient if Gracillaria density was increased.

Abstract

Zooplankton abundance, diversity and community structure were estimated in the seagrass beds of Awur Bay, Jepara. The samples were collected during 36 hours observation in situ, from Nopember 1994 to April 1995 and covered a total 29 species, which holoplanoton, 7 meplankton and 6 nectobenthos. Result of Shannon Weaver Diversity Index and Cluster Analysis based on Bray Curtis values revealed patterns of zooplankton abundance, diversity and community structure. These are discussed with regard to sampling time and zooplankton life cycle. The zooplankton abundances range between 6800 – 22777 individuals/m3, with average 13698 individus/m3, while the diversity range between 2,48 – 2,86 and cumulatively 2,93. Zooplankton abundance and community structure fluctuated due to seasonal changes, during the first two months of the research, and increasing to a stable level in April 1995. This pattern of zooplankton community structure appears to be related to the ecological capacity and hydrodynamic. Keywords : zooplankton, seagrass, abundance, diversity, community structure, Awur Bay, Jepara.

Abstract

Excessive fishing capacity is a core issue in marine capture fisheries. In relation with the capacity issue, this study was conducted to determine annual changes of fishing capacity of the small-pelagic fishery at FMA-714 Banda Sea using time-series data of 1985 until 2006 which was analyzed using data envelopment analysis (DEA) approach. The small-pelagic fishery was found to be excess capacity in 17 out of 22 DMU. And there was indication of overcapacity in the period of 1989 until 1998. The fishery had a tendency to be not efficient with the highest score of 23.7% at DMU-1998. Consequently, alternative fishery management policies are needed to reduce fishing inputs of the fishery at the FMA-714 Banda Sea.

Abstract

Land-based pollution has severely damaged nearshore corals reefs in the Jepara area, Central Java. Effect described here include reduced coral cover and diversity, high coral mortality, reduced reef habitat complexity, and increased bioerosion intensity, compared to reference reefs in the Karimunjawa Islands National Marine Park, Central Java. Furthermore, the polluted reefs have negative net carbonate production indicating net reef erosion. Reef health parametres based on coral cover and diversity and on net carbonate production are inversely correlated with chlorophyll A concentration, suggesting eutrophication of coastal waters as a key agent of reef degradation. Untreated sewage dumping, agricultural runoff, and aquacultural effluent all contribute to nearshore eutrophication in Central Java, but it is not possible from this study to determine which of these types of land-based pollution is most responsible for degradation of Central Java reefs. Efforts to restore the condition of degraded reefs must begin with controlling sources of land-based pollution.

Abstract

Liquid-liquid membrane contactor (LLMC) is a new desalination process using microporous hydrophobic membrane. The temperature difference at two solution-membrane interfaces gives rise to a trans membrane vapor pressure difference that drives the flux. In this work, the effect of process parameters on LLMC performance has been done. The process parameters consist of feed and permeate temperatures, cross flow velocity, feed concentration and mode of operation. In addition, this paper focuses on the development of LLMC by using solar and wind as energy sources. In this experiments micro porous hydrophobic hollow fiber polypropylene membrane with 0,2 mm was used as a contacting device. The experiment were conducted at temperature of 25-80oC, cross flow velocity of 0.02-0.2 m/s and solute concentration of 0-110.000 mg/L.  Results show that the flux was influenced by the feed and permeate temperatures, the cross flow velocity and the concentration of solute. The increase of feed temperature increases the flux exponentially, whereas the flux seems to increase linearly with the increase of cross flow velocity. On the other hand, the flux was not significantly affected by the solute concentration. Furthermore, the flux in the counter current mode was lower than in the co-current mode. The average pure water fluxes obtained were in the range of 2-3 l/(m2h), whereas the products concentrations were in the range of 2-5.3 mg/L depending on the feed concentration. The operation of solar powered LLMC up to 10 days shows a very stable performance.

Abstract

a large number of techniques, including a variety of indices, have been proposed and developed forassessment. Structural and functional variability have been summarized through both univariate andmultimetric indices as integrative indicators in environmental monitoring programs. In general, multimetricindices are considered to be sensitive, stable, and robust, thus offer a promising approach for ecologicalassessment. This study is aimed to assess the degree of sensitivity for several indices in terms of their abilityto determine environmental changes. Based on macrofaunal data, several univariate and multimetric indiceswere used to assess and compare the level of disturbance at fallowed farm and reference (control) sites. Thetwo multimetric indices, the AZTI’s Marine Biotic Indices (AMBI) and Ecological Quality Ratio (EQR), wereused as integrative indicators to assess the categorisation of each sampled site. The results showed that acombination of multimetric index and univariate indices provide a better assessment. The categoriesdetermined by multimetric indices seem to be in accordance with level of disturbance expressed by thetrophic analysis, multivariate and graphical analyses used in this study. The AMBI has the ability to detectlarge scale differences among sites. However, AMBI was unable to discriminate slight changes in themacrobenthic assemblages between sites, as have been exposed by EQR.

Abstract

A local isolate of green algae called C1 from Jepara waters is usually used as a source for carotenoid supplement for animal fisheries in the local area. This indigenous algae has been successfully purificated.  Although the local isolate was known as eucaryotic green algae Dunaliella, our previous molecular study by 18S rDNA analysis to determine the species of this organisms showed negative result. In order to improve carotenoid production especially detection of biosynthetic pathway from the organisms investigated in this study, the main purpose of this study was species determination of local isolate of green algae based on microbiologycal, ecophysiologycal and molecular characterization. The results of this research  indicated that local isolate of green algae posseses Cyanobacteria characteristic, especially Synechocystis. Analyses with 16S rDNA sequence from genome of green algae isolates were also in accordance with these results, showing close similarities with Synechocystis 16S rDNA sequence.  However, it should be noted that, instead of having Synechocystis dominant feature, it was also found that local isolate of green algae exhibit different characteristic in having chlorophyll a, chlorophyll b and lack of phycobillins. This character was typical for abberant Cyanophyta, Prochlorophyta.
