Holothuria scabra is a commercial tropical sea cucumber species, which has been exploited severely in recent years. This study was conducted at the Mataram Marine Bio Industry Technical Implementation Unit for 20 days aiming to determine the relationship between wet and dry weight of sea cucumbers with and without colon. Results of regression analysis between wet and dry weight show a significant positive correlation. The relationship between wet and dry weight without the colon is y = 0.1685x – 0.2319 (R2 = 0.9236) whereas the wet and dry wet of the intestine is y = 0.075x + 0033 (R2 = 0.791).

Abalone is a herbivore marine animal which feeds on seaweed. Abalone culture has a good prospect in terms of price, market share and simple culture technique. Thus, a study was conducted with the aim of finding out an effective and efficient abalone culture technique in terms of feed use and density. In this study, a 42 cm diameter plastic container with a 22 cm height was used. Three vertically arranged containers were used as the experimental group which were put into a net box and hung onto a raft so that the containers were placed in a 4 m depth below the sea surface. The juvenile of abalones being used came from a hatchery production that has been adapted to cages environment with Gracilaria sp. and Ulva sp. feed. The initial density of abalones was 450 for each container, with the initial weight of 2.6-3.2 g and the 2.5-2.7 cm shell lengths. The abalones were fed with Gracilaria sp. and Ulva sp. seaweeds with different Gracilaria sp./Ulva sp. proportions, i.e. 100/0% (A); 80/20% (B); and 60/40% (C) as the treatments. Each treatment consisted of two replications. After three months of rearing period, densities of abalones were reduced to be 190 for each experimental unit. Weight and shell length of abalones were measured every month by measuring 25 abalone samples from each experimental unit. The result of the experiment showed that the increase in the Ulva sp. proportion in the feed increased the growth of abalones and decreased the feed conversion. Feeding with Gracilaria sp./Ulva sp. proportion of 60%/40% allowed the best growth of abalones. The decrease of abalone density in the experimental unit after three months of rearing also produced an increase in their growth.

The growth of the dinoflagellate, Scrippsiella sp. from Narragansett Bay, USA and the chain-forming benthic diatom, Melosira cf. moniliformis from Kendari Bay, Indonesia was evaluated under optimized laboratory conditions to investigate potential new candidates for shrimp aquaculture hatchery feeds. Isolation of microalgae was performed using capillary pipets in f/8-Si for Scrippsiella sp. and f/2 for M. cf. moniliformis. Isolated cells were placed in an incubator with a photoperiod of 12:12 hour (light : dark cycle), at light intensities of 62-89 μmol photons.m-2.s and at temperature of 20oC. Microalgae cells were cultured in 150-mL Erlenmeyer flasks containing 100 mL of f/2-Si medium for Scrippsiella spin triplicates and in 50-mL culture tubes containing 20 mL of f/2 medium for M. cf. moniliformis in four replicates. The cells in culture flasks were used in cell counting experiments while those in tubes were for fluorometer trials. Growth evaluation was conducted every 2-3 days. The diatom, M. cf. moniliformis was in logarithmic phase when observed at 2 to 7 days after inoculation and showed a high growth rate (μ = 0.52 day-1) and high division rate (k = 0.76 day-1, 1 division every 1.3 days). Logarithmic phase of Scrippsiella in culture flasks was started on day 7 to 30 (μ = 0.17 day-1 and k = 0.25 day-1 or 1 division every 4 days). In culture tubes, Scrippsiella sp. reached logarithmic phase at day 21 to 47 (μ = 0.12 day-1 and k = 0.18 day-1, 1 division every 5.65 days). This study indicates that M. cf. moniliformis can be used for aquaculture hatcheries feed but further study for the nutrition composition is needed. Scrippsiella sp. is potentially toxic for aquaculture at high densities, therefore they should be assessed carefully if used for aquaculture feeds.

Vibriosis is one of main diseases of the black tiger shrimp Penaeus monodon infected by pathogenic bioluminous bacterium Vibrio harveyi that can cause mass mortalities in shrimp culture. The bacteria can also trigger the disease white spot syndrome virus (WSSV). An effort to produce shrimp disease-resistant strains has been done through transgenesis technology with antiviral gene transfection. By this technology, it is expected an increase in the immune response of shrimp in a variety of diseasecausing pathogens. This study aimed to determine the immune responses (total haemocytes, haemocyte differentiation, and phenoloxydase activity) of transgenic tiger shrimp against pathogenic bacterium V. harveyi. Research using completely randomized design, which consists of two treatments and three replications. Test animals being used were transgenic and non-transgenic shrimp with size, weight 3.93±1.25 g and a total length of 7.59±0.87 cm. Treatments being tested were the injection of bacterium V. harveyi (density of 5x106 cfu/mL) of 0.1 mL/individual on transgenic (A) and non-transgenic shrimp (B). Immune response parameters such as total haemocytes, haemocyte differentiation, and phenoloxydase activity were observed on day 1, 3, and 6 days after challenging. Data were analyzed using t-test by SPSS software. The results showed that the total haemocyte of transgenic shrimp was not significantly different (P>0.05) from non-transgenic shrimp, but haemocyte differentiation and phenoloxydase activity were significantly different (P<0.05) especially on sixth days after being exposed to the bioluminescent bacteria. The study results implied that transgenic shrimp has a better immune response compared than non-transgenic shrimp.

Seaweed is an important aquaculture commodity that could contribute on climate change mitigation, related to its ability on absorbing CO2, as one of the green house gases, through photosynthesis. This study aimed to analyze seaweed potencies on carbon sequestration in the context of climate change mitigation while still resulting optimum production as primary purpose and to analyze the carrying capacity of Gerupuk Bay in order to manage sustainability of seaweed aquaculture. Seaweed, (Kappaphycus alvarezii) was cultivated with long-line system in Gerupuk Bay, West Nusa Tenggara, during five months for three cultivation cycles. Samplings were conducted at days-15, 30, and 45 with CO2 absorption rates as main parameters. Water carrying capacity was calculated to determine the ability of Gerupuk Bay waters for supporting development of sustainable seaweed aquaculture. The results showed that absorption rates of CO2 by seaweed (K. alvarezii) were different at each sampling days of cultivation periods; the highest value was at 10-20 days of cultivation. CO2 absorption analysis resulted based on sampling days of cultivation period could be appl ied to formulate the strategies for management of sustainable seaweed aquaculture, with optimal production and positively contributed to the environment. However, waters carrying capacity should also be considered as major aspect in the application of seaweed cultivation management, thus it can run continuously without causing conflicts with other interests.

Mass mortality of giant freshwater prawn (Macrobrachium rosenbergii de Man) in grow-out farmers occurred in early February 2012 at Instalation Coastal of Aquaculture Samas, Bantul, D.I. Yogyakarta. The clinical sign of shrimp was whitish coloration on abdominal and tail muscle. The sympton was the same as in other cases of mortality caused by prawn Macrobrachium rosenbergii nodavirus (MrNV) and Extra Small Virus (XSV). Prawn samples were diagnosed by standard protocols Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR) using specific primers and histopathology analysis. The result showed that all samples indicated positive 13/15 the MrNV and 5/15 positive XSV, and there were 4/15 positive samples both (MrNV and XSV). Analysis of histopathology showed that damaged muscle was indicated by the presentation of necrotic tissues with nuclear pyknosis or degeneration of muscle in infected tissues. Based on diagnosis by RT-PCR and histopathological, mass mortality of the giant freshwater prawn in Indonesia is determined to be caused by “white muscle disease (WMD)/white tail disease (WTD)”.

Spatial distribution of brackishwater pond soil has important role in the system of bioenvironment including brackishwater pond environment. This research was aimed to determine the spatial distribution of some chemical characteristics of an acid sulfate soil-affected brackishwater pond in coastal area of Luwu Regency South Sulawesi Province, Indonesia. ALOS AVNIR-2 images (acquisition 16 May 2008, 16 October 2008, 17 September 2009) were integrated with Indonesian Topographic maps to obtain base map. Sampling soil points were determined by simple random sampling in 104 points for two different soil depths i.e. 0-0.2 m and 0.5-0.7 m. A total of 18 soil chemical characteristics was measured in the field and analyzed in the laboratory. Geostatistic using kriging method in the ArcGIS 9.3 software was used to interpolate the data. The results of this study indicated that in general pond soil chemical characteristics in Luwu Regency could be categorized with high variability or relatively heterogenic wi th the value of var iation coefficient more than 36%. The soil characteristics that explain acidity had shown similar pattern in spatial distribution as well as other soil characteristics with soil nutrient. The high value of pH and low value of PO4 were generally found in the northern part of Luwu Regency, including East Lamasi, East Walenrang, Bua, and Ponrang Subdistricts. It is recommended that soil management in brackishwater ponds of Luwu Regency could be based on soil chemical characteristics so its could improve the production through minimizing the input, increasing carrying capacity, and avoiding environmental degradation.

Humpback grouper (Cromileptes altivelis) has been successfully spawned in 2000 by IMRAD (Institute of Mariculture Research and Development) and there are already the third generation (F3) currently. The reproductive aspects need to be studied to support the success of seed production. Humpback grouper reared in floating cage (F1 and F3) had matured (gonad stage 4) while F2 fish reared in concrete tanks has spawned. Gonadal maturity stage of 38 fishes from first generation (F1) and 35 fishes from the third generation were observed in June 2013 and compared to gonadal maturity stage of 18 fishes from the second generation observed in June 2009. Samples were measured in total length and body weight and gonads were taken for histology preparation to determine gonadal maturity stage and the sex. From the histological observation of the gonads, it showed that all female humpback grouper were in early maturity stage (stage I and II) with gonadal maturity index between 0.12% and 5.45%. Further, it was observed that the same gonad was found in different maturity stage and concluded that humpback groupers were multiple spawners (asynchronous). By determining gonadal maturity level, it was also known the minimum size for grouper ready to spawn.

Primary cell culture from tail epidermal tissue of koi carp (Cyprinus carpio koi) was developed. Cells were grown in Leibovits-15 medium supplemented with 20% fetal bovine serum and antibiotics (Penicillin/Streptomycin and Kanamycin). Cell growth was observed in a range of incubation temperature (17oC±2oC, 22oC±2oC, 27oC±2oC, and 32oC±2oC) in order to determine the optimum temperature. The cells were able to grow at a range of temperature between 17oC to 32oC with optimal growth at 22oC. Primary cells infected with koi herpes virus produced typical cytopathic effects characterized by severe vacuolation and deformation of nuclei, which is consistent with those of previous reports. Artificial injection experiment by using supernatant koi herpes virus SKBM-1 isolate revealed that it could cause 90% mortality in infected fish within two weeks. PCR test with Sph I-5 specific primers carried out with DNA template from supernatant virus, pellet cell, and gills of infected fish showed positive results in all samples (molecular weight of DNA target 290 bp). The cells were found to be susceptible to koi herpes virus and can be used for virus propagation.

The success of spawning is influenced by internal and external factors. One of the factors that affect the var iabi li ty of Pangasianodon hypophthalmus female reproductive is the change of seasons that cause disrupted continuity of the seed availability, especially in the dry season. In the present study, combination of PMSG (pregnant mare serum gonadotropin) + HCG (hormone chorionic gonadotropin) hormone injections was done to induce gonad development. The treatments in this study were without hormone injections as control (A), injection of PMSG 10 IU/kg + HCG 10 IU/kg (B), and injection of PMSG 20 IU/kg HCG + 10 IU/kg (C). Injections were conducted at intervals of two weeks as many as six times. The results showed that gonad maturation generally occurs 2-4 weeks after estradiol-17 peak. PMSG + HCG hormone injections gave a significant effect on increasing the quantity and quality of eggs production. The fecundity in the A, B, C treatments, were 233,700±220,676; 300,305±24,581 and 488,433±142,228; respectively. Number of larvae produced from the A, B, C treatments, were 156,979±170,838; 229,997±18,081 and 362,713±101,850; respectively. Combination of PMSG 20 IU/kg + HCG 10 IU/kg hormone injection gave the best result on fecundity and the number of larvae production.
