Abstract

In this research, clove and cinnamon were prepared by grinding to produce spice powder and by solvent extraction to produce spice extract. They were stored in plastic and glass jar at ambient temperature for two weeks to observe the change of sensory quality. The spices were then combined and applied to short-bodied mackerel (Rastrelliger neglectus) and the total mesophilic microbes were enumerated. The best concentration of spice combinations which gave the lowest total mesophilic microbe was 2% of clove and 4% and cinnamon in form of powder and 4% of each spice in form of extract. The spice powder and extract, as well, were applied to short-bodied mackerel which has been prepared under various treatments. The treated fishes were stored and the histamine content was analyzed after two hours storage at ambient temperature. The result showed that spice powder and extract could decrease histamine content in short-bodied mackerel processed with and without boiling. Statistic analysis showed that there was significantly difference of each treatment on histamine content (p<0.01). Spice powder in combination with boiling process showed the higher percentage of the decrease of histamine content (94%) than that without boiling (42.5%), spice extract with boiling (28.3%) and without boiling (21%).

Abstract

Application of remote sensing and geographic information system (GIS) for planning of biocrete shrimp ponds development was studied in the coastal area between Opak River and Progo River, Bantul Regency. Analysis of land suitability for biocreteshrimp pond used a multi-scoring of some physical variables, i.e. slope, soil texture, distance from coast line, distance from river, annual rainfall, flooded frequency, and landuse. Spatial analysis used a GIS software (ER Mapper 5.5, ARC/Info 3.5 and ARC/View GIS 3.2). The results showed that suitable land fotbiocreteshrimp pond was 73,6 ha. It found on beach ridge area that was distributed at Srandakan, Sanden, and Kretek Region. However, considered on the Detail Planning of Spatial Arrangement at Southern Coastal of Bantul Regency (RDTK PantaiSelaatnKabupatenBantul) and suistanable aquaculture planning, the development of biocrete shrimp ponds should be limited to 36,8 ha (50%), i.e. 18,4 ha ponds at Srandakan and 18,4 ha ponds at Sanden. Biocrete shrimp ponds had to be built at distance about 300 m from cost line.

Abstract

Samples of yellowfin tuna (Thunnus albacares) were taken from three locations Bali, North Sulawesi and North Maluku. The glucose-6-phosphate isomerase (GPI) was analyzed from liver using allozyme electrophoresis method. Polymorphism of GPI enzyme was observed and four alleles (A, B ,C, D) were found in Bali population, three alleles (A,B,C) were found in North Maluku and North Sulawesi populations. Heterozygosity values, from Bali, North Maluku and North Sulawesi were 0.419; 0.417; 0.143 respectively. Genetic distance between North Sulawesi and North Maluku were 0.029, and with Bali population was 0.353. These results indicated that North Maluku and North Sulawesi population were not separate by geographic barrier, therefore genetic distance of both populations was closed. However, those populations were genetically separated to the Bali population might be due to major hydrological barrier.

Abstract

Plankton monitoring were conducted in hatchery and rearing hapas of red tilapia (Oreochromis sp.) to know plankton abundance and its utilization by fish during 98 days. Be-weekly plankton samples and fry fish guts were taken from fish hapa rearing, meanwhile brood fish gut were taken monthly. Be-weekly plankton and water monitoring were also applied in fish rearing without feed, water outside of hapas and river. Two units of bamboo frame, 6 x 6 m2 divided into 4 blocks respectively, were used for fixing 2 x 3 x 1 m3 hatchery hapa, and 1 x 2 x 1 m3 rearing hapa. Commercial feed was given daily to brood stock at the rate of 2% of the total fish weight and fry at the rate of 40%. Plankton density and composition in hatchery and rearing hapas were higher density than water reservoir and river. All size of red tilapia consumed selected plankton species, about 31.34-38.89% of existing species. Dominant plankton in hapa water were: Navicula, Closteriopsis, Sphaerocystis, Surirella dan Arthrodesmus and among them were prefered by red tilapia as natural food, namely Navicula, Surirella, Closteriopsis dan Sphaerocystis. Water quality parameters were still suitable for fish growth and breeding, but dissolved oxygen tended to low due to high plankton abundance.

Abstract

The aims of this experiment was to obtain data and information on the percentage of decrease in the levels of cannibalism, growth and survival rate of mud crab crablet (Scyla serrata) by feeding trash mixed with tryptophan and glycine. This research was conducted in the wet lab experimental pond installation at Center of Research and Development of Brackish Water Aquaculture Maranak, Maros for 28 days using 12 aquariums each measuring 80x40x60 m3. Crablets (C-20) from the hatchery were used for this study, measuring 5.3+0.2 mm in width and 0.15+0.02 g in weight. Ten crablets were stocked in each aquarium. The treatments applied were (A): trash fi sh tilapia (Tilapia mosambica), (B): trash fi sh + tryptophan and (C): trash fi sh + glycine, with three replicates per treatment. Feeding dose was 25% of the total biomass crablet while the dose of tryptophan and glycine were 1.0% of the amount of feed given per aquarium. Feeding was done twice a day in the morning and evening. Variables observed were the growth in carapace width, weight, level of cannibalism, survival rate and water quality parameters. The results showed that   adding the amino acids tryptophan and glycine in trash fi sh feed  at 1.0% of total biomass could signifi cantly (P<0.05) suppress the level of cannibalism krablet without affecting the growth rate (weight and width of carapace) and   increase the survival rate of the mud crab krablet.
