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 experiment was conducted in order to figure out the effect of incubation temperature on embryonic development of yellowfin tuna, Thunnus albacares eggs. Five different incubation temperatures were applied as treatments, i.e.: 24°C, 26°C, 28°C, 30°C, and 32°C with 3 replicate each. Ten micro plates with lid (IWAKI, Japan) were used; each has 6 well and 10 mL volumes. Five micro plates were used for experiment and five for balance on shaker. Three well of each micro plate were filled with 8 mL ultra violet sterilized sea water and 50 fertilized eggs. Temperature was set using Multi Thermo Incubator which has 5 level racks. Temperatures were set from the lowest to the highest on bottom to upper rack order. To maintain eggs dispersed in the medium, shaker on each rack was operated at 150 RPM. The embryo was monitored every 30-60 minutes depends on embryonic stage development using Microscope which was connected to Digital Camera DXM 1200F. Image analyses by Image Analyzer Program. The results showed, incubation temperature was significantly affect (P<0.05) embryonic development and hatching time of yellowfin tuna (Thunnus albacares) eggs. Optimum incubation temperature for embryo development and hatching was 28°C. Decreased on incubation temperature slows down embryo development at all stages, and vice versa, increased on incubation temperature accelerates embryo development.

Genetic diversity at molecular level has been assumed to correlate with fitness related traits. However, accumulating evidences showed that the nature of that correlation has been variable. This study was aimed to explore the nature and possible mechanisms underlying that correlation by focusing on growth related traits in African catfish, Clarias gariepinus using microsatellite molecular markers. Fifty individual African catfish of 110 days-old were sampled and subjected to both morphological and molecular analyses. The standard length, total length and body weight as well as allelic scores of six microsatellite loci were measured on each individual. Indices of microsatellite diversity, namely individual multilocus heterozygosity (MLH) and mean microsatellite allelic distance (mean d2) for individual level, and mean observed heterozygosity (Ho) and single-locus heterozygosity (ho) for group level, were correlated to those traits using Pearson correlation coefficient (r). The Hardy Weinberg and linkage disequilibrium were carried out to explore the possible mechanisms underlying correlation. The results showed that at individual level the MLH and mean d2 were weakly correlated with standard length, (r=0.25, p<0.05) and (r=0.24, p<0.05), respectively. At group level, Ho was correlated with both standard and total length (r=0.99, p<0.05) while ho identified two loci, Cga03 and Cga06 significantly contributed to the correlation. Combining all relevant information, present study identified associative overdominance, both local effect and general effect hypotheses might responsible for the observed correlations.

Indonesian Aquaculture Journal Vol 4, No 2 (2009): (December 2009)
Publisher : Center for Fisheries Research, Agency for Marine and Fisheries Research and Human Resource

Koi herpesvirus (KHV) is an emerging virus that infects koi and common carp (Cyprinus carpio) with mortality up to 95% within 7 days. The disease is rapidly spreading worldwide including to Indonesia. However, it has only been documented in koi and common carp. The aim of this research was to evaluate the susceptibility of fish cell cultures originated from cyprinid and non-cyprinid fish to KHV. Koi Fin (KF-1) and Koi Tail (KT-2) cell lines derived from koi carp and SSN-1 cells originated from fry of striped snakehead were used in this study. The cells were inoculated with tissue extract of KHV-infected koi carp (experiment 1) and virus stock of KHV (experiment 2). The cultures were incubated at 22oC and the onset and type of cytophatic effect (CPE) were observed for 21 days post inoculation. The results of experiment 1 showed that CPE was observed in KT-2 at day 6 post inoculation. In the experiment 2, however CPE was observed in KF-1 and KT-2 cells at day 4 post infection. CPE was not observed in SSN-1 of either experiment 1 or experiment 2. CPE was characterized by extensive vacuolization of the infected cells. Polymerase chain reaction (PCR) assay of cell and tissue culture supernatants confirmed that KF-1 and KT-2 showing CPE were indeed infected with KHV. The results indicated that KF-1 and KT-2 cells were susceptible and SSN-1 was resistant to KHV. The implication of these findings was also discussed in the paper.

The objective of this research was to evaluate the nonspecific immune response and resistance of Litopenaeus vannamei fed with nucleotide, β–glucan, and protagen diets. Shrimp juveniles with an average weight of 5.39±0.56 g were reared in glass aquaria at a density of 15 shrimps/aquarium. Shrimps were fed three times a day for four weeks at a feeding rate of 3%/bw/day. Treatment diets consisted of A: basal diet (without immunostimulant), B: β–glucan, C: protagen, and D: nucleotide, each with three replicates. At the end of feeding period, the shrimps were intramuscularly injected with Vibrio harveyi 0.1 x 106 cfu.shrimp-1. Total haemocyte count (THC) of shrimp fed with nucleotide-diet was significantly different compared to that of control shrimp (p=0.01), but not different compared to shrimp fed with protagen-diet. PO activity also increased significantly in shrimp fed with nucleotide-diet (p=0.02). β–glucan diet could also increase THC and PO activity, but compared to the control, the increase was not significantly different. Overall, PO activity of shrimp fed with nucleotide, β–glucan, and protagen diets was high (>0.35). Oral administration of nucleotide, β–glucan, and protagen for four consecutive weeks significantly increased resistance of shrimp to disease (<0.01) where the highest resistance rate was observed on shrimp fed with nucleotide-diet. Growth of shrimp fed with nucleotide-diet was significantly different compared to that of control shrimp (p<0.01), as well as to β–glucan, and protagen-treated shrimp. As a conclusion, supplementation of nucleotide into shrimp pellet enhanced nonspecific immune response and growth performance better than β-glucan, and protagen.

The study was based on eight specimens from a single population of Palembang pufferfish. We used a comprehensive approach comprise behavioral record, the Random Amplified Polymorphism DNA technique, exteriorly genital observation and the description of morphological coloration distinctive to recognize gender. Annotation from captivity has yielded that two genders in couple were possessed the prominent social respond in shoaling-fidelity. When the gonadal process has been released by maternal part, eggs and offspring were kept by male and there is no tolerable contact of female were given, here the female has become more cannibalism. Male adult has more brown-blackish and occasionally more flukes-dark on the half upper horizontal body it has less towering bulk and only has one genitalial hole. Female furthermore is recognizable with the present hight-bulk and has more yellow overall flukes in coloration and widely bright yellowish-dark from abdomental part to the edge of middle half of the body. Contrary, female has two genitalian holes. RAPD also has confirmed a concordance linkage what we are previously expected. We found an important mutation 176 bp for both gender. Among the scaffold obtained, scaffold 33 is a common scaffold identified within T. palembangensis and Takifugu, it has a sufficient score bit of 36.2 with a length of nucleotide 1,758,880 bp. Moreover, this scaffold is the result from primer OPP-19 in the female of T. palembangensis, we thus can finally distinguish their sex status. The scaffold 33 might relate to the gene SOX. Our attempt may hatch a new horizon for institutional developers, aquarist and conservationist in case of surety for sustainable natural population and to ensure their stock for consumption and trading ornament requirement.

Most histopathologycal studies of the red sea bream iridovirus (RSIV) disease in red sea bream have been performed by studying enlarged cells as well as necrotized cells in the spleen and other organs. These enlarged cells have been named as inclusion body bearing cells (IBCs). However, few information is available about detail of ultrastructural features of IBCs produced in the target organs of RSIV-infected fish. In the present study, details of ultrastructural features of IBCs that were produced in the spleen tissue of naturally RSIV-infected red sea bream were investigated under electron microscope. Under electron microscope, RSIV-infected red sea bream had the presence of two types of IBCs: typical IBCs allowing virus assembly within viral assembly site (VAS), and atypical IBCs which degenerate organelles without virus assembly. Other infected-cells were observed as necrotized cells forming intracytoplasmic VAS with large numbers of virions, but without the formation of the distinct inclusion body. Morphogenesis steps on RSIV-infected red sea bream were observed as filamentous-filed virions, partially-filled virions and complete virions with 145-150 nm in size. These findings confirmed that RSIV-infected red sea bream were characterized by formation of typical and atypical IBCs as well as necrotized cells.

Mangrove snapper, Lutjanus argentimaculatus is one of highly economic value of marine fish commodity. Culture of this species has been developed a few years ago. Basic data on biological aspect is still limited whereas those kinds of information are needed. Histological study to determine development of internal organs of the larvae of mangrove snapper was conducted. Amount of 15-20 larvae each from 1 day after DAH hatching (1 DAH) up to 30 days after hatching (30 DAH) were collected, fixed in Bouin’s solution for 4-6 hours and then transferred into 70% alcohol. The samples were then embedded in paraffin wax and the sections were stained with haematoxylineosin (H&E). Results showed that the eye retina of the mangrove snapper larvae well developed on 3 DAH, whereas their digestive tract was on 5 DAH. Under this condition, the larvae started feeding as showed by present of natural food tissues in the intestine. Development of digestive tract and other internal organs reached their complete form like in adult fish after 20 DAH.

Macrobenthic in mangrove ecosystems plays an important role as removal particles from the water column to the sediments. Ecology indexes of macrobenthic communities were used in this study as an indicator for the fertility of mangrove pond ecosystems. The study was carried out at mangrove pond in Blanakan, West Java. Data was collected from four sampling sites: opened pond (TB), sylvofishery pond (TS), sedimented pond (TT), and conservation pond (TP). Some ecological indexes such as Margalef’s Index (R), Shannon-Wiener Index (H’), Pielou Evenness Index (E), and Simpson Dominance Index (D) were used to analyze macrobenthic communities. The results showed that infaunal macrobenthic communities were stable at TP with R: 1.91±0.42, H’: 1.59±0.30, E: 0.74±0.14, and D: 0.29±0.12. They were unstable at TB with R: 1.63±0.80, H’: 1.36±0.32, E: 0.74±0.06, and D: 0.35±0.07. The macrobenthic communities can be used as indicator for the fertility of mangrove pond in Blanakan, West Java.
