Abstract

This article aims at explaining factors affecting the successfulness of coastal communities of Gili Indah in constructing a governance structure of coral reef management. Coral reef management in this region has changed from an ineffective state regime to a local governance. From the perspective institutional economic theories, the emergence of a governance is an institutional change phenomena that are affected, among others, by actors’ characteristics such as organizational experiences, opportunistic behavior, environmental awareness/perception, planning horizon, bargaining power, technological skill and certainty; and trust, distrust and reputation. Using a distributional conflict theory of institutional change, the results of this research can draw a conclusion that institutional change process of coral reef management in the locality was strongly assumed affected by those factors.

Abstract

Fisheries management at Indonesia during the time is relatively responsive to unsustainable management.This caused by this management which is not yet considering population dynamic aspects, such as intrinsicgrowth rate, catch ability of fishing gears and carrying capacity. The objectives of these researches are todevelop and decide of the intrinsic growth rate and catch effort effects to white shrimp population dynamicat Riau Province. Modeling was conducted to growth and harvesting model with numerical simulationtechnique. The result of numerical simulation represents that intrinsic growth rate of white shrimp is equal0.88 tons/years and carrying capacity is equal 38,023.26 tons. Existence standard effort 54,447 trips/yearscause decreasing maximum population growth became 10,941 tons of population with growth rate 2,831.3tons. The optimal and sustainable management of white shrimp fisheries at Riau Province must be considerpopulation dynamic aspects.

Abstract

Extracts of methanol, ethyl acetate, and n-hexane of four species of Indonesian seagrasses were used to determine the total phenol contents and their antioxidant activities.  Total phenol contents of each extract was determined by spectrophotometer using Follin-Ciocalteu reagent, and the antioxidant activity was measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH).  The profile of fibers of each fresh seagrass was performed according to an enzymatic-gravimetric method. All of methanol extracts contained high number of total phenol, except Syringodium isoetifolium the highest content was found in ethyl acetate extract; so that methanol extracts of Thalassia hemprichii, Cymodocea rotundata, Enhalus acoroides and ethyl acetate extract of Syringodium isoetifolium had the highest activities on scavenging DPPH radical.  The phenol content in tropical seagrasses was tending to soluble in polar and semi-polar solvents. There was no significant different on the content of total fibers, with values ranges was from 14.32 g/100 g to 15.39 g/100 g.  However, the highest content of soluble fiber was found in Enhalus acoroides (8.93 g/100 g) and significantly differed to others.

Abstract

The increasing use of herbicides in agriculture sectors have receives great attention with respect to their potential toxic effect on reef-building corals of Indonesia. One chlorinated compound, 2,4-dichloro phenoxy acetat (2,4-D), has widely been used as a herbicide and has become a substantial environment pollutant. Controlled tolerance experiment testing 2,4-D was performed on Porites sp. And Galaxea sp in Marine Station, Teluk Awur, Jepara. The effect 2,4-D on coral mortality and zooxanthellae expulsion were investigated. The result showed that short duration (48 h) laboratory test demonstrated dramatic effect on sloughing and death of coral. The median lethal concentration (LC50-48) was determined to be 23.20 ppm on Porites sp and 10.26 ppm on Galaxea sp. There were no significant differences between Porites sp and Galaxea sp on the toxic response of   2,4-D compounds.

Abstract

Seventeen strains of bacterial symbionts which are resistant to heavy metals, were isolated from the tissue of coral Goniastrea aspera, from Awur Bay, Jepara Waters. Screening procedures involving solid and liquid synthetic media containing Cd2+, resulted in the selection of seven Cd resistant strains, which showed a quantitative removal of Cd2+  by range of 68-90% of the initial Cd2+  concentrations (5 ppm) tested. One of these strains, CD15, was selected further to examine its molecular and physiological characteristics. Based on 16S ribosomal DNA sequencing and microbial characterization, the CG15 isolate is closely related to Pseudoalteromonas sp. This is the first report on the natural Cd metal tolerance levels of coral bacteria

Abstract

The objective of this study was to investigate the effect of escape vent on catch of black damsel, then sizeselectivity of escape vent will be estimated to predict the retention probability of escape vent on black damsel.The result of this study indicated that comparison of diversity index between the catches of escape vent potsand non escape vent pots were 3.07 and 3.38 respectively. Installing escape vent pots significantly impovecatch of commercial size black damsel i.e 56.6% of total catch. A Kolmogorov-Smirnov two sample testindicated that there is significant difference on the length distribution of black damsel between escape ventpots and unvented pots. The result of size selectivity curve indicated that fish size smaller than 8 cm lengthhave high probability to escape from escape vent pots. Length at 50 % retention occurs at fish length of 14.67 mm.

Abstract

Dried salted  anchovy is a rich source of  protein which is processed by boiling, salting and drying. During processing the protein undergoes change, e.g. protein myofibril  becomes denatured to some extent , and it can be visualised using SDS-PAGE protein pattern. Protein can also react with lipid to form brown colour mainly in  high temperature. The result of the analyses shown that there were differences in proximate composition between different samples of  anchovy. There were not much difference in sample band pattern for fresh , boiled ,  boiled and dried anchovy samples. The highest solubility protein was found in the Indonesian dried salted anchovy while the lowest was in fresh sample. The colour of boiled sample was the  whitest in comparison to fresh, boiled and dried, Indonesian dried salted anchovy and Japanese boiled. Except for Indonesian dried salted anchovy,  brown colour and development of  lipid oxidation was not detected.

Abstract

This study was the first attempt to examine the molt stage and molting cycle in relation to the ovarian development of M japonicus in Tokyo Bay In particular the study was done to reveal molting and spawning relationship, to predict reproductive peaks and thus larval recruitment and to investigate the possibility of multiple spawning within one molt cycle in natural condition, Ohh: three out of five stages were represented in the samples since the early premalt (A) and ecdysis (E) occured in a very short time. There occured was a co-occurrence between ovarian maturation and molt stage, in which maturing ovaries occurred at B (late postmolt) to D, (earlv premolt) stage, mature ovaries at C (intermold to D; (late premoly, and spent ovaries at D, to D,. Molting and spawning synchronization was observed in kuruma prawn, in which molting fequency was highest prior to and at the end of spawning season. There was a possibility of multiple spawning within single molt cycle in wild kuruma prawn, since there were enough time for spent ovaries to redevelop into mature ones.

Abstract

The Southern Islands of Singapore are known to contain coral reefs which are high in biodiversity. However, the diversity of soft corals had received little attention to date. This study was conducted to determine the soft coral diversity in Singapore reefs as well as to conduct preliminary bioactivity tests on the organic extracts from these soft corals. A 100-meter line transect was used to survey soft corals at a 3m depth at ten different sample sites. Sclerites from samples were used to identify the soft corals to the generic level. This study uncovered the following genera of soft corals: Carijoa spp., Cladiella spp., Sinularia spp., Lobophytum spp., Sarcophyton spp., Stereonephthya spp., and Nephthea spp. In addition, an unidentified genus of soft coral was observed at Kusu Island. Cladiella spp. yielded the highest number of colonies, and Sarcophyton spp. had the highest coverage in terms of total colony diameter. The brine shrimp (Artemia salina) toxicity assay was carried out to screen for toxicity of the soft coral extracts at concentrations of 10, 100, and 1000 ppm. Results showed high levels of toxicity in extracts of Sarcophyton spp. and Cladiella spp., indicating that these soft corals are potentially good sources of bioactive compounds for drug discovery.
