Publisher : Center for Fisheries Research, Agency for Marine and Fisheries Research and Human Resource

Two different colors (green and brown) of Kappaphycus alvarezii have been farmed in Indonesian waters for many years. This study aimed at comparing two ‘varieties’, i.e. green and brown, both genetically and morphologically. Samples for DNA analysis were collected from a farmer in Pinrang Regency, South Sulawesi. Five universal primers i.e. Ca-01, Ca-02, P-40, P-50, and DALRP were selected to obtain DNA genetic markers in differentiating the green and brown varieties. To compare coloration patterns during cultivation and the growth performance of both varieties, a field experiment was performed in a seaweed farming area in Pinrang Regency, during dry season of August-September 2004. The result of genetic assessment showed that the five selected primers revealed different RAPD banding pattern for both varieties. P-50 and DALRP primers demonstrated the greatest amplification in differentiating RAPD fragment between green and brown varieties. Fragment 900 bp and 1.300 bp were consistently generated in the green variety but were not amplified in the brown variety. The result of the field study confirmed that the coloration pattern of green and brown varieties was fixed; no interchange in color occurred during one crop cultivation.

Aeromonas salmonicida is responsible in many cases of furunculosis outbreaks resulting in economic loss of freshwater aquaculture. Four isolates of A. salmonicida have been isolated from fish collected in four different regions in Indonesia and its clonal relation has yet to be determined. In the research, A. salmonicida isolates and ATCC atypical isolate as the control had been checked for their clonal relation using Restriction Fragment Length Polymorphism (RFLP) method in which restriction enzyme of AluI, HaeIII, MboI, and EheI were used. PCR test results using the primers 16S rDNA amplicon gave a positive response to the 1300 bp band. The result of RFLP analysis showed that A. salmonicida atypical isolates from Indonesia represent subspecies smithia except isolates from C. macropomum in Yogyakarta in MS and 16S rDNA regions. Isolates from Jambi, Pontianak and Semarang showed a slight variation on enzyme restriction sites. Isolates number 2, 3, 4 and 5 had the same restriction sites using AluI enzyme with MS primer. The restriction enzymes that could give the best result for RFLP method of A. salmonicida were HaeIII, MboI and EheI.

Publisher : Center for Fisheries Research, Agency for Marine and Fisheries Research and Human Resource

Characteristic of Megalocytivirus infection has been known to produce formation of inclusion body bearing cells (IBCs) on internals organs of fish predominantly on spleen and kidney. Megalocytivirus that infected grouper is known as Grouper Sleepy Disease Iridovirus (GSDIV). This study was conducted to answer the effect of entry sites of GSDIV on distribution of enlarged cells formed on the internal organs of humpback grouper Cromileptes altivelis. Enlarged cells were observed histologically under the light microscope on spleen, head kidney, trunk kidney, liver, gill, heart, stomach, intestine, muscle and brain. Entry sites were designated to intramuscularly injection, intraperitoneally injection, dipped gill and inoculum added feed. Enlarged cells were formed on spleen, head kidney, trunk kidney, liver, gill, heart, stomach, muscle, except on intestine and brain. All the entry sites resulted in formation of enlarged cells on spleen, head kidney, trunk kidney, liver, heart. Spleen and head kidney were the most frequent observed organ. These results suggested that distribution of enlarged cells were not affected by the entry site of GSDIV.

The study was carried out in Brebes District, the North coast of Java. Tiger shrimp farming in Indonesia, particularly in this area faced some problems which caused by improper pond preparation, disease, and low seed quality. Probiotic was applied in pond to solve this problem. The aim of this study was to evaluate the production of tiger shrimp in ponds with probiotic applications. Six experimental ponds (each measuring 0.5 ha) were selected of which three were probiotic ponds and three were controlled. Tiger shrimp postlarvae (PL-30) were stocked at density of four shrimps/m2. Tiger shrimps were reared for three months. Shrimps were fed by commercial pellet. In the first month, shrimp were fed about 7%-5% of the total biomass; in the second months, 3.5%-3% of the total biomass; and in the third month, 2.5%-2% of the total biomass. The treatments in this study were the application of probiotics with concentration of 3 mg/L that were given every five days and control (without probiotics). The results showed the rearing period was 92 ± 6 days in probiotic ponds and 76 ± 16 days in controlled pond. The shrimp in controlled pond should be harvest earlier caused by the high mortality. The average final weight was 16.2 ± 0.7 g in probiotic pond and 15.6 ± 1.9 g in controlled pond. The survival rate was 64.13 ± 12.63% in probiotic pond and 44.17 ± 14.15% in controlled pond. Production was 208 ± 46 kg/pond/cycle in probiotic pond and 123 ± 6 kg/pond/cycle in controlled pond. The result showed that probiotic plays an important role in maintaining water quality parameters and health management as well as increases the survival of shrimp.

Research on genetic differentiation among populations of Chromobotia macracanthus Bleeker from Sumatra, based on sequencing gene of mtDNA Cytochrome b and nucleus DNA RAG2 has been done. The objectives of the study were to obtain the representation of genetic differentiation among population of clown loach fishes or botia (Chromobotia macracanthus) from Sumatra and Kalimantan and to estimate the time divergence of both population group of botia. Samples of botia population were taken from 3 rivers in Sumatra namely Batanghari, Musi, and Tulang Bawang and one river from Kalimantan namely Kapuas. The genetic analysis was based on the sequencing of mtDNA Cytochrome b and nucleus DNA RAG2. The statistical analysis was done by using APE package on R language. The parameters observed were: nucleotide diversity, genetic distance, and neighbor-joining tree. The result showed that the highest nucleotide diversity was fish population of Musi, while the other two populations, Tulang Bawang (Sumatra) and Kapuas (Kalimantan), were considered as the lowest genetic diversity especially based on nucleus DNA RAG2 sequencing. Based on mtDNA Cytochrome-b sequencing, the most distinct population among those populations based on genetic distance were fish populations of Musi and Kapuas. According to the result of neighbor-joining tree analysis, the populations of botia were classified into two groups namely group of Sumatra and group of Kalimantan. The estimation of time divergence among group of population of Sumatra and Kalimantan based on mtDNA Cytochrome b was about 9.25—9.46 million years (Miocene era). The high genetic differences between groups of Sumatra and Kalimantan suggested that the effort of restocking botia from Sumatra into Kalimantan has to be done carefully, because it may disturb the gene originality of both botia populations.

Publisher : Center for Fisheries Research, Agency for Marine and Fisheries Research and Human Resource

Heritability estimates of commercially important traits are of important in order to seek the best strategy of selective breeding program to be implemented. A study aimed at estimating the magnitude of this parameter for growth related traits, expressed in wet weight (WW), total length (TL), and standard length (SL), has been carried out in giant freshwater prawn (GFP). Particular emphasis was given to investigate the effect of ages and culture conditions on the magnitude of the heritability estimates. Nineteen full-sib families were established through individual pair mating. The families, namely groups of offsprings derived from each mating pair were raised through three stages of rearing activities: first-stage nursery (40 days), second-stage nursery (70 days), and grow-out rearing (130 days). Heritability for growth at each stage was estimated through the method of full-sib analysis or intraclass correlation. Components of variance used to produce the heritability estimates were obtained through the method of analysis of variance. Results showed that heritability estimates varied with both ages and culture conditions. The heritability estimates (± standard errors) at 40 days for WW (0.69±0.151), TL (0.64±0.148), and SL (0.70±0.144) were higher than those observed at 70 days (WW = 0.24±0.15; TL = 0.22±0.15; and SL = 0.20±0.14) and 130 days (WW = 0.24±0.058; TL = 0.22±0.05; and SL = 0.20±0.60). A similar pattern was found with respect to the culture conditions. The estimates found in grow-out at lower stocking density (5 individual/ m2) days (WW = 0.24±0.058; TL = 0.22±0.05; and SL = 0.20±0.60) were higher than those observed at grow out at higher stocking density (20 individuals/m2) days (WW = 0.12±0.058; TL = 007±0.05; and SL = 0.14 ± 0.60). The possible causes of the observed patterns and implications that these findings may have on the breeding program of GFP are discussed.

The present study identifies existing mariculture activities and its constraints in SE Sulawesi, along with its geo-physical attributes in the Province.This allows for a better understanding the potential, current and future status of mariculture development in the area and making sure its sustainability. The study was conducted to map the existing mariculture activities in SE Sulawesi. Data collection was performed in June 2009. Spatial and attribute data of the existing mariculture were acquired by interviewing fish farmer using open-ended questionnaire and analyzed using ArcGIS 9.x. Key water quality parameters consisted of temperature, dissolved oxygen, pH, salinity, depth, clarity, and turbidity and analyzed using STORET Indeks. Three big clusters of existing mariculture activities are located in Kendari, Muna and Buton areas, collectively serving as both a source of mariculture products and a market destination or transit location. All surveyed locations of existing mariculture activities in SE Sulawesi show relatively optimal water quality conditions. Site capacity and suitability analysis of existing or potential areas of mariculture activities and development have largely not been considered by stakeholders involved in managing coastal areas, resulting in crowded and unmanaged development with multiple overlapping economic activities in some areas. Piloting of integrated ‘value-adding’ mariculture industries (e.g. raw material, processed products and ‘ready to eat’ industries) might help ease some if not all of the existing economic problems of the mariculture sector.

Spatial distribution of brackishwater pond soil has a vital role in the system of bioenvironment including brackishwater pond environment. This research was aimed to determine the spatial distribution of brackishwater pond soil characteristics in Pekalongan City, Central Java Province. A total of 59 sampling points each with two different soil depth samplings were determined by simple random method. A total of 21 soil characteristics were measured in the field and analyzed further in the laboratory. Geostatistic with Kriging Interpolation method in the ArcGIS 9.3 software were used to depict the distribution of the data across the landscape. Furthermore, the spatial distribution was presented by using ALOS AVNIR-2 image. Research result indicates that in general, pond soil in Pekalongan City can be classified as soil with high variability or relatively heterogenic with the value of variation coefficient more than 36%. Soil characteristics which have similar pattern of spatial distribution are acid sulfate soil and soil nutrient content. High value of pH, organic matter, and total-N of soil, and on the other hand, low value of PO4 were generally found in the pond area of Krapyak Lor Village, while in Pekalongan City, it was found high clayish soil content but relatively homogenous. It is recommended that pond management must be based on soil characteristics which are different from one area to another. The soil characteristics itself can be drawn and assessed through spatial distribution.

In early rearing period, the larvae of Asian catfish (Pangasianodon hypophthalmus) were fed with Artemia nauplii at the first 10 days. Since Artemia cyst price is quite expensive, it will be a constraint in development of the Asian catfish hatcheries. This study was conducted to evaluate the abundance of natural life food in pond and utilization of it for substitute Artemia cyst in Asian catfish larvae rearing. The Asian catfish larvae at the age of 5 days after hatching were used as the test fish. Sampling of natural life food in fertilized pond was conducted before the fish stocked. The fish larvae were stocked in pond after ten days from ponds fertilizing. At the 2nd day after larvae fish was stocked, five fish samples were collected for identify the type of food which consumed by fish. The results showed that abundance of natural life food which found in ponds ranged from 70,200 to 180,600 individual/L. Index of diversity, uniformity and dominancy for phytoplankton and zooplankton ranged from 2.407 to 2.732; from 0.032 to 0.043 and from 0.112 to 0.204, respectively. Based on the analysis of digestive tract of fish, it was found that index of selectivity and index of preponderance for natural life food ranged from 0.94 to 0.62 and from 0.17 to 67.03, respectively. This study suggested that Asian catfish larvae at the age of five days after hatching can utilize the natural life food in ponds to replace the use of Artemia cyst in indoor hatchery system.

ISOLATION AND GROWTH OF DINOFLAGELLATE, Scrippsiella sp. AND DIATOM, Melosira cf. moniliformis IN CONTROLLED CONDITIONS Wa Iba

Publisher : Center for Fisheries Research, Agency for Marine and Fisheries Research and Human Resource

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.
