Abstract

HighlightsEleutherine americana was a plant that was known to contain antibacterial alkaloids, steroids, phenolics, and flavonoidsEleutherine  americana extract was able to inhibit the development of V. harveyi both through in vitro and in vivo tests on tiger shrimp (Penaeus monodon).The use of vibriosis antibiotics in tiger shrimp was often not controlled so the results obtained were not effective AbstractThe use of vibriosis antibiotics in tiger shrimp was often not controlled, so the results obtained were not effective. The addition of antibiotics would cause resistance to V. harveyi. Eleutherine americana is a plant that is known to contain antibacterial alkaloids, steroids, phenols, and flavonoids. This study aimed to determine the effectiveness of inhibitory effects of E. americana extract against V. harveyi through in-vitro and in-vivo tests on tiger shrimp larvae. In-vitro testing consisted of 7 treatments and 3 replications, namely treatments A (0.1%), B (0.2%), C (0.3%), D (0.4%), E (0, 5%), F ethanol 70% (K-), and G chloramphenicol 0.01% (K +) treatment. The largest inhibition zone diameter of E. americana extract was shown in treatment C (0.3%), with an average value of the inhibition zone produced of 7.5 mm. Challenge test with V. harveyi concentration of 107 CFU / ml in the in-vivo test consisted of 5 treatments and four replications namely; A treatment without E. americana extract, B extract 6 ppm, C extract 12 ppm, D extract 18 ppm, and treatment E without extract and V. harveyi. The results of the challenge test with V. harveyi bacteria were significantly different in control (chloramphenicol 0.01%), where the highest survival rate was in the treatment of 12 ppm extract (43.34%). E. americana extract could inhibit the development of V. harveyi bacteria both through in-vitro and in-vivo tests on tiger shrimp (Penaeus monodon).

Abstract

HighlightsCoral cover, rugosity, and reef fish abundance was determinedThe relationship between coral cover and rugosity and fish abundance was analyzed.Coral cover in East Java were categorized as medium – good.The rugosity index and the fish abundance were highest in Bangsring Waters.There are no relationships between coral cover and fish abundance, but there is relationship between rugosity and fish abundance.AbstractA coral reef is one of the most complex and specific ecosystems in a tropical area. It is identified by its high productivity and biodiversity. This research aims to discover the percentage of coral reef cover and rugosity, as well as the fish abundance in several locations in East Java, Indonesia. In addition, this research aims to investigate the correlation of coral reef cover and rugosity with the density of coral reef fish. This research was conducted in three locations, i.e., Bangsring Waters of Wongsorejo District, Banyuwangi Regency; Gili Noko Bawean Island, Gresik Regency; and Kramat Island, Gili Genting District, Sumenep Regency. This research employed the Line Intercept Transect (LIT) method to calculate the percentage of coral reef cover, the Chain Intercept Transect (CIT) method to determine the coral reef rugosity, and the Belt Transect method to estimate the fish abundance. From this research, it was revealed that the highest coral reef cover was in Bawean waters, while the highest rugosity was in Bangring waters. In addition, the highest coral reef fish density was in Bangsring waters. Meanwhile, the coral reef fish density did not correlate with the percentage of coral reef cover. In contrast, it correlated with the coral reef rugosity.

Abstract

HighlightsThe halophilic bacteria were isolated from salt-pond soil.Isolate C2 was identified as the best protease producer.Isolate C2 was identified as B. amyloliquefaciens strain UBCAbstractProtease is an important enzyme for various industries, such as pharmaceuticals, leather production, meat processing, protein hydrolyzate, food products, and waste processing industries. This study aimed to isolate and identify protease-producing bacteria isolated from salt-pond soil at the Tuban Regency, East Java, Indonesia. Bacterial communities in the soil samples were firstly isolated from the soil samples by culture-dependent technique on Luria Bertani agar enriched with 5% NaCl. Thereafter, bacterial colonies that grew on the media were purified and screened for their protease production using a skim-milk agar. The bacterial colony which produced protease was further identified using phenotypic (gram staining) and genotypic assays (the 16S rDNA sequence). The result showed that one isolate out of six (isolate C2) obtained from the soil sample was observed to produce a protease enzyme. Based on its 16S rDNA sequence, the isolate was identified as Bacillus amyloliquefaciens strain UBC. These results suggest that B. Amyloliquefaciens strain UBC is a salt-tolerant bacterium (halophilic bacteria) which has the potential to be further developed for protease-producing biological agents.

Abstract

HighlightEight species of sea cucumber was found in four intertidal location in Southeast Moluccas and Tual watersHolothuria atra had the highest densitySea cucumber biodiversity in Southeast Moluccas and Tual waters categorized as lowLocal culture can be used for sustainability of sea cucumber resources management  AbstractA study on the community structure of sea cucumber in Southeast Moluccas and Tual needs to be done due to the important role of sea cucumber in both ecologically and economically sustainability. This study aimed to investigate the community structure of sea cucumber in this region as one of the supporting information for the utilization and management of the resources. A survey was conducted by sweeping the target area, by walking and also snorkeling. The location where each sea cucumber found was marked using a GPS, the specimen was weighed, and some were preserved for species analysis. Water quality was measured at each location, while the substrate and vegetation were recorded. This study revealed different composition of species in the investigated area. As many as 8 species of sea cucumber were found, in which four were of genus Holothuria, three were of genus Stichopus and the rest were of genus Bohadschia. Species H. atra has the highest density. In general, the diversity index was relatively low (< 2), the evenness index was 0-81 indicating that the community was depressed. Certain species dominated at most of the investigated sites (0.50-1), and a low margalef index is 0-1.7. To conclude, the community structure of sea cucumber in Tual and Southeast Moluccas was in a depressed condition.

Abstract

HighlightsThe results of the model and observation showed the similarity of the amplitude and phase formedAt the highest tide was in the position above the Sea Mean level and the current velocity was lower than when heading to the tideThere was a difference in the direction of the current when heading towards high tideStratification of the water column in both seasons tended to be classified in well-mixed watersAbstractBalikpapan Bay is significant as a link between the cities within and outside of East Kalimantan by becoming the primary path used for local transportation and distribution of produced goods. The various anthropogenic activities increased liquid wastes and debris, which flowed through channels and rivers along the bay. This study aimed to determine tidal current patterns in Balikpapan Bay and its influence on salinity and temperature distributions. This study applied a baroclinic three-dimensional (3D) hydrodynamic model, employing wind, tides, and density variations, resulting from the differences of temperature and salinity, as the model input. To simulate the tidal current flow, we applied MOHID Water Modeling System, which the tidal current patterns depicted current directions and speeds at the different tidal conditions. During the displacement toward the high tidal condition, the water mass moves northwestward entering the river body, while at the displacement toward the low tidal condition, the water mass moves southeastward, which flows toward the coast and without the bay. The current speed varies at certain tidal conditions. At the highest tidal condition, the surface elevation ranged 1.3 - 1.5 m above mean sea level; the current rate is lower compared to the displacement toward high tidal condition, which ranged from 0.01 - 0.15 m/s. At the lowest tidal condition, the surface elevation reached 1 - 1.2 m below mean sea level, and the weaker flow velocity took place (less than 0.15 m/s). The results also showed that the water mass temperature tends to be higher in the inner part of Balikpapan Bay, the Balikpapan Bay waters profile that is increasingly shallow towards the bay head also causes this area to tend to have a higher temperature. Also, areas located on the inside of the bay tend to get more freshwater input from rivers, so this area has lower salinity while the area located at the mouth of the bay tends to be of higher salinity because it gets a lot of mass input of seawater from the Makassar Strait.

Abstract

HighlightsThe main problem to ensure the good management in fisheries was multi species fishPrecautionary approach needed to get a good view of the important criteria in fisheries managementNeeded a multi criteria and index to make a final conclusion of the any criteriaNatural history and population dynamic parameter important input to sustainability indexValidation model in sunda strait as preliminary approach will help to get a good data and resultAbstractTorpedo scad species known are both economic and ecologic important pelagic fish that fishing catch tends to increase last a few decades. For sustainability, in the long term, needed a management strategy that complies with measurable fish population indicators. This effort is a part of the precautionary approach in fiseries management in related exploitation. This research was conducted in Labuan fishing port performed for more than 8 months and then analyzed with population parameters. Composite analysis by multi-criteria approaches found that the average score of Torpedo scad is 1.48 and then grouped as moderate sustainability. Schooling fish, including torpedo scad has been moderate until high sustainability levels. Overall population status in this area refer to moderate potential risk and needs a precautionary approach on management.

Abstract

HighlightsLitopenaeus vannamei has been established as alternative to Penaeus monodon to shrimp farming in several countries.Increased importance of in situ microorganisms both in regulating biogeochemical cycles within the culture environment and in directly affecting shrimp growth and survival.To improve water quality in aquaculture is the application of probiotics and/or enzymes to ponds. AbstractIntensive shrimp farming has raised environmental issues due to aquaculture pollution, which is caused by uneaten feed, feces, organic matter, and toxic compounds (ammonia and H2S). One way to solve this issue is by using probiotics. Thus, this study aimed at investigating the effect of probiotic administration (Pseudomonas sp. and Bacillus sp.) at varying concentrations on total organic matter in the rearing water, feed conversion ratio, feed efficiency, and growth rate of white shrimp (Litopenaeus vannamei). This study used a Completely Randomized Design consisting of four treatments: T0 (without the probiotic supplementations), T1 (probiotics at 106 CFU/ml), T2 (probiotics at 107 CFU/mL), T3 (probiotics at 108 CFU/mL) with three replicates each. The results showed that the administration of probiotics at different concentrations had a significant effect on the total amount of organic matter, feed conversion ratio, feed efficiency, and specific growth rate of white shrimp. Administration of probiotics at a concentration of 107 CFU/ ml had the lowest organic matter in the rearing water, 138 mg /Lt. While probiotic administration at 108 CFU/ ml gave the lowest feed conversion ratio (1.22), the highest feed efficiency (81.57%) and the best growth rate (2.25%/day). This research suggests that the administration of 107-108 CFU/ ml probiotics could be applied to reduce organic content in the rearing water and improve the growth performances of white shrimp.
