SATIATION AND DIGESTION RATE OF MANGROVE SNAPPER FINGERLING (Lutjanus argentimaculatus) Made Suastika; Philip Teguh Imanto
Indonesian Aquaculture Journal Vol 2, No 1 (2007): (June 2007)
Publisher : Center for Fisheries Research, Agency for Marine and Fisheries Research and Human Resource

Mangrove snapper is an economically value in domestic as well overseas market, but supplies are mostly sourced from the wild. Observations on satiation and digestion rate of fingerlings was undertaken to provide basic information for culturing mangrove snapper. Ten fingerling mangrove snapper (body weight 3.8—19.5 g) were stocked into each of nine plastic 200 L tanks. After starvation for 24 hours, fish were fed with chopped ‘trash’ fish and the amount of eaten feed was record as satiation data. Feeding data was recorded after 4 hours feeding. The satiation rate for juvenile mangrove snapper followed the power regression line Y=0.4503x-0.6472. Thus, in larger juveniles the satiation rate was lower. Digestion rate followed a polynomial regression line, indicating that digestive activity was not the same during observation time, and analysis of two linear regressions shown that the flection point for digestion rate occurring after 10 hours when digestion rate reached 72%. These results indicate that the optimum feeding rate for mangrove snapper fingerling was 72% of satiation, and optimum feeding frequency two times per day.

Genetic improvement through selective breeding relies on the genetically-controlled phenotypic variability in the character of interest. Therefore, the extent of phenotypic variability in the population to be selected is an important parameter, as it potentially influences the population’s response to selection. This study was aimed to investigate the effect of inbreeding on the survivability, growth, and phenotypic variability of giant freshwater prawn (GFP), Macrobrachium rosenbergii. Two GFP populations of different inbreeding levels, namely 25% and 0%, respectively, were formed by mating of individual broodstock with known pedigree. Study was conducted for two months starting from newly hatched larvae up to nursery stage (30 day-old post larva). Phenotypic variability profile, expressed in the morphometric mean and coefficient of variation (CV) of twenty one morphometric characters were measured and evaluated. Results showed that in general, the inbred populations had lower values in the mean of all characters (100%), indicating that they suffered from inbreeding depression. Similarly, a lower CV values were observed in sixteen (75%) of the morphometric characters measured, indicating a potential reduced of genetic gain when they are used in selective breeding program. These results suggest the importance of controlling inbreeding level in breeding population that adverse effects resulted resulted from inbreeding can be minimized.

One of the most popular techniques in mass production of all or nearly all male tilapia population is through sex reversal. However, cross mating of YY super male with regular brood-stock is gaining popularity and has been practiced by aqua-culturists. This study was conducted to evaluate the performance of 2 populations of sex reversed tilapia (sex reversed with dietary application of 17-α methyl testosterone, SRT-1, and sex reversed with dietary administration of imidazole, SRT-2) and 1 population of genetically male tilapia (GMT) derived from YY super male until the end of fingerling rearing period. Mixed sex tilapia (MST) derived from normal mating was used as the control population. The results showed that the daily growth rates of SRT-1, SRT-2, GMT, and MST were 0.12, 0.11, 0.20, and 0.07 g/day, with survival rates were 57.83%, 64.67%, 39.67%, and 68.78%, respectively. The GMT has higher harvest yield than the other populations; SRT-1 (+15.73%), SRT-2 (+6.37%), and MST (+20.82%).

EFFECT AND COMPARISON OF RECYCLING AND STAGNANT FRESHWATER ON PERFORMANCES (GROWTH AND SURVIVAL RATES; FISH QUALITY) AND PROFITABILITY OF THE ORNAMENTAL FISH Barbus schwanefeldi (KAPIAT) REARED AT 4 DIFFERENT DENSITIES Sudarto Sudarto; Agus Priadi; Jack Slembrouck; Laurent Pouyaud; I Wayan Subamia

Several ways have been done to encounter shrimp disease affecting cultured shrimp in Indonesian ponds in the last two decades. This research was aimed to find out the effect of different application of probiotic RICA4, RICA5, and RICA3 method on survival rate and production of white-leg shrimp (Litopenaeus vannamei) cultured in ponds aerated with supercharge blower. RICA probiotics are bacteria probiotics produced by the Research and Development Institute for Coastal Aquaculture, originally isolated from seaweed and sea sediment. This experiment was carried out in completely randomized design using nine 250-m2 experimental ponds stocked with 15 shrimp fries/m2. There were three treatments namely: A=alternate use of three probiotics RICA4, RICA5, and RICA3; B=combination use of three probiotics RICA4, RICA5, and RICA3; and C=control (without probiotic), each treatment with three replications and cultured with supercharge blower. Variables observed in this study were survival rate and production of the shrimp calculated at the end of experiment, total vibrio count (TBV) and total plate count of common bacteria (TPC) of the pond waters and sediments monitored every two weeks. The results showed that application of probiotic RICA4, RICA5, and RICA3 applied either in alteration or in combination significantly increased survival rate (P<0.05) but not on production (P>0.05) of the white-leg shrimp. TBV/TPC ratio in the control pond waters after 10-weeks culture (over than 10%) was relatively dangerous for the cultured white-leg shrimp. This shows that application of probiotic could prevent the growth of Vibrio spp in the cultured shrimp pond water.

Indonesia is one of the richest regions in the world in terms of biodiversity. However, recent evidence has shown that tropical forests destruction has maintained at a high rate over the last few years in this country. At the same time, living resources in Indonesian freshwater ecosystems are important: this country ranks at number seven in terms of production of inland capture fisheries with 323,150 tonnes in 2008. Freshwater fishes represent 42% of the total estimated ichthyofauna, concentrated in 0.01% of the total water covered environment. This environment is closer to human activities, making it critically vulnerable to adverse impacts. Furthermore, there has been some recent debates on the general sustainability of fisheries and aquaculture production systems. This research was focused on initiating a multi-scale study of fish biodiversity in freshwater environments. Two specific actions have been started. A review based on the analyses of the existing scientific literature and of databases on fish taxonomy and distributions. In parallel to this work, a global analysis of the distribution of fish diversity in Indonesia was undertaken. This work aims at identifying the major features of this resource as well as its current and future threats.

Red sea bream iridovirus (RSIV) has been known to induce cellular enlargement as cytophatic effect (CPE) in cultured cell line. In the present study, grunt fin (GF) cells were treated with RSIV. After advanced of CPE, the cellular enlargement were harvested, processed and analysis under electron microscopy. Electron microscopy revealed inclusion body bearing cells (IBCs), and enlarged and rounded cells allowing virus propagation within the intracytoplasmic virus assembly site (VAS). Most were enlarged cells. These enlarged cells were divided into three cells types. Enlarged cells of the type I, which contained many mature virions were numerous in the number rather than enlarged cells of type II which contained many immature viral particles and enlarged cells of type III which allowed assembly of a few virions. These results determined that basic ultrastructure feature of RSIV infected GF cells is formation of IBCs and cells containing a few, many mature and immature viral particles within VAS.

Identification of growth hormone (GH) gene in a target fish is the first step in the construction of “all fish genes transfer vector” to generate transgenic fish. The research was done to identify and characterize the GH gene of Pangasionodon hypophthalmus. There were several activities performed in identifying the GH gene: RNA extraction, cDNA synthesis, PCR amplification, and DNA fragment isolation. The characterizations were done using the nucleotide sequencing engine ABIPRISM 3100. The results were then analyzed using BLASTN/P and GENETYX version 7 program. The full-length GH gene of P. hypophthalmus was 1151 bp in length, coding for an open reading frame (ORF) of 603 bp. The 5’ and 3’ untranslated regions of the GH gene were 22 bp and 526 bp long, respectively. The GH gene of P. hypophthalmus had some common characteristics that are owned by GH genes, such as single tryptophan residue (W) on the 104th amino acid, 5 cysteine residues (C) on the amino acid 71, 135, 173, 190, and 198 and a motif of Asn-Xaa-Thr on C terminus which is the potential location for N-linked glycosilation. Polyadenylation signal (aataaa) was on the 14 bp at the upstream of polyadenylation location. Growth hormone of P. hypophthalmus consisted of over 200 amino acids from GH cDNA deduction. The highest proportion of amino acid composition was leusin (14%) while the lowest was tryptophan (0.5%).

The effects of an artificial commercial feed supplementation on larval rearing and crablet production of mud crab Scylla tranquebarica. In mass production of mud crab seeds, only rotifer and Artemia nauplii are usually fed to mud crab larvae rearing until the larvae develop to crablet stage. The supplementation of artificial commercial feed from zoea-3 stage is expected to supply an essential nutrient required for an optimum larval development. The research was aimed to determine the optimum dosage of commercial feed supplementation for a successful larval rearing to produce crablet in hatchery. Newly hatched larvae of mud crab were stocked at a density of 100 ind./L. The larvae were fed with rotifer and Artemia nauplii. Microbound artificial commercial feed sized <100 microns (protein 52%, fat 14,5%, fiber 3% and water content 10%) was supplemented to the larvae from zoea-3 to megalopa stage at different dosages namely: a). 0.5 mg/L/2 days; b). 0.75 mg/L/2 days; c). 1.0 mg/L/2 days; d). 1.25 mg/L/2 days. Larval population, larval development indices (LDI), megalopa occurrence index (MOI) and crablet production were observed and measured. Water quality (ammonium, nitrite, Total Organic Matter (TOM), and total Vibrio sp. count were also monitored. The LDI, MOI, and crablet production from each treatment were compared and tested using one way-ANOVA. The results showed that the survival rate of larvae at zoea-5 ranged between 29-33%. The LDI was not significantly different (P>0.05) among treatments. However, the MOI of treatment A and B at day 21 ph was significantly higher (P<0.05) compared with treatment C and D. In addition, the crablet production in treatment B, C and D were significantly higher (P<0.05) compared with treatment A. It was concluded that the supplementation of artificial commercial feed in larval rearing of S. tranquebarica could be applied at the dosage range of 0.75-1.25 mg/L/2-days from zoea-3 until crablet (C-7) stage.

Infection of Megalocytivirus cause serious mass mortality in marine fish in South East Asian countries. The aim of this study was to produce recombinant of GSDIV capsid protein and its protection to humpback grouper Cromileptes altivelis against grouper sleepy disease iridovirus (GSDIV). A major capsid protein (MCP) was selected for use as a crude subunit vaccines. This gene target (MCP) was inserted to the protein expression system vector of pET SUMO and cloned in cells bacteria Escherichia coli strain BL-21. The MCP was succeded to be induced using 1 mM of IPTG. Results of protein analysis using MALDI TOF-TOF indicated that the MCP has measurement of 49.566 kDa with PI index of 6.00, and contained 453 amino acids. BLAST homology analysis exhibited that the amino acid sequence of the MCP showed high similarity with MCP of Red Sea Bream Iridovirus (RSIV). E. coli expressing MCP protein was inactivated using 0.03% formalin overnight and washed using PBS. The inactivated E. coli as a crude subunit vaccine was then injected intramuscularly to humpback grouper juveniles. Subsequently, the juveniles were challenged tested with GSDIV. The juveniles vaccinated with the MCP recombinant bacteria showed significantly higher survival rates than control those vaccinated with PBS. Thus, the MCP fusion protein is considered as a potential vaccine against GSDIV infections in grouper.
