Blue swimming crab (Portunus pelagicus) colors have variations from different habitats and they have different vitality. The purpose of this study was to analyze the diversity of the P. pelagicus using morphometric and 16SrRNA mitochondrial sequence. There were three groups of blue swimming crab characterized by differences in color and density patterns of spots. The result of Canonical discriminant analysis showed that there were morphometric differences among the three groups. The main distinguishing morphometric characteristics are the ratio of carapace width and length as well as the ratio of the length and width of cheliped merus. The third group of crab is also has similarity about 98-99% by the Portunus pelagicus 16S rRNA sequences available in gene banks. These studies had concluded that differences in color and pattern of the spot density have also morphometric and genetic differences. At least there were two groups based on genetic variation of Portunus pelagicus from Barru Regency waters which may have a variety of different properties. Further research is needed to study the adaptation abilities of the two groups of crab on the condition of aquaculture as a potential domestic animal.Keywords: Crab; Portunus pelagicus; Morphometric; 16S rRNA.

The spermatozoa quality of goramy two days after sub-zero freezing was examined. The quality of spermatozoa examined included motility, viability, and abnormality. We aimed to determine the optimum concentration of glycerol protecting spermatozoa during preservation. We used 0%, 1%, 3%, 5%, 7%, and 9% of glycerol, respectively. Sperms were diluted by the combination of glycerol and fish ringer (1 part of sperm + 3 part of solvent). The dilute sperms were then equiliberated at 4°C for 45 min, and were freezed at -34°C for two days. Thawing was then carried out at 30°C for 2 min. Based on Dunnet test, 5% of glycerol was the optimum concentration maintaining spermatozoa motility (75.95±4.76)%.Keywords: glycerol; Osphronemus goramy; spermatozoa motility, viability, and abnormality; sub-zero freezing

Indonesia shrimp products are often rejected by foreign countries due to high antibiotic content, whereas a few years ago Japan and European countries are set 0.05 ppb permitted to consume by the people, but now the restriction will be smaller is 0.01 ppb. Some farmer was stopped to use antibiotics but the residues still found in fish flesh. Possible origins antibiotics are environment because are antibiotic residues still exist in the mud, water organism which lived in pond. Samples originating from shrimp, mud, water and other biota will be examined according to the method of Thomson (1966) of the Pfizer Corporation and the Association of Official Analytical Chemist (Horwitz, 1980). The purpose of this study was to determine the origin of antibiotic present in the cultivation or farming system that does not use antibiotics in shrimp production.: a. Antibiotics obtained from ponds in the Tuban area is 1.8 ppm (mud), 0.8 ppm (water) and 2.1 (biota). b. a. Antibiotics obtained from ponds in Gresik were 0.6 ppm (mud), 0.3 ppm (water) and 1.2 (biota). c. Antibiotics obtained from ponds in the area of Situbondo are 0.3 ppm (mud), 0.1 ppm (water) and 0.6 (biota). d. a. Antibiotics obtained from ponds in the area are 0.3 ppm Probolinggo (mud), 0.2 ppm (water) and 0.6 ppm (biota).

Blue swimming crab (Portunus pelagicus) is the important world fishery resource, but the crab larval rearing faces high mortality problem. The aim of the research was to compare survival and growth rate of larvae resulted from wild and domesticated broodstock blue swimming crab. Domesticated and wild broodstock were used to produce larvae. Domesticated broodstock was selected from repeated reared crab until third generation. Selection of the broodstock mainly based on the survival and growth rate. The wild broodstock was collected from Makassar Strait Sea. Larvae from the two sources of broodstock were reared in the conical tanks with density of 50 zoeas per liter. After reaching megalopa phase, then, the larvae were transfered into concrete tank completed with shelter and it were reared until crab phase. Crab phase was reared for 18 days, then these seed were released into the brackishwater pond for further domestication step. Larva from zoea to crab were fed with rotifer, artemia, fresh small shrimp and diet. The result showed that domesticated broodstock produced higher survival rate (P<0.05) larvae, faster larval stage changes (P<0.01) and uniform larval growth compared to the larvae from wild broodstock. It is clearly shown, the use of domesticated broodstock of blue swimming crab produced better larva quality and quantity than the wild broodstoock crab.Keywords : blue swimming crab, larvae, domestication, broodstock selection, faster growth

Blue swimming crabs (Portunus pelagicus) from Makassar Strait have some variations in color and pattern of spots on the carapace. The purpose of this study was to analyze the habitat preferences blue swimmer crab species complex from Macassart Straits. Crabs were grouping based on the difference of color and pattern of spots on the crab carapace to identify the variety of crabs. Habitat was observed salinity, depth, and substrate type. The results of PCA analysis showed a tendency of each population occupies a different base substrates (P<0.01). Substrate type also correlated with depth and salinity. The conclusion of this study is the difference in the color and pattern on the carapace thought to be different species or varieties and they occupy different habitats. Preferences of the different habitats for different population groups are very important information for the development of blue swimming crab aquaculture in the future.

The efficacy of mineral-amino acid complex of Zn,Mn,Cu,Fe and Se for white shrimp, Litopenaeus vannamei, diet compare to inorganic mineral on growth performance, feed utilization and immunity was studied. The treatments were 1) the control diet with contained inorganic minerals of Zn, Mn, Cu, Fe and Se (T1-C1X). 2) treatment diet of the combination of inorganic mineral and organic mineral-amino acid complex70:30 at the same level of control diet Availa Zn, Availa Cu, AvailaMn, Availa-Fe 100and Availa-Se 1000 (T2- Inorg:org 1X) and 3) The sole mineral-amino acid complex Availa Zn, Availa Cu, AvailaMn, Availa-Fe 100 and Availa-Se 10000 at 0.5X (T3-Org 0.5X). The results indicated that there were not significantly different (P>0.05) on the growth performance, feed consumption, feed conversion ratio, Protein efficiency ratio and survival rate. The immune status in term of hemocyte count were significantly increase (P<0.05) in group of shrimp fed mineral-amino acid complex than control. Drip loss of peel shrimp on 96 hr was low (P<0.05) in group of shrimp fed mineral-amino acid complex than control. Therefore, mineral-amino acid complex of Zn, Mn, Cu,Fe and Se at 0.5X (T3-Org0.5X) exhibited the same growth performance, feed utilization and survival rate as inorganic mineral (T1-C1X) and combination of inorganic and organic mineral-amino acid complex (T2- Inorg:org 1X). Hence, organic mineral-amino acid complex has the efficacy around 200% of inorganic mineral on shrimp growth performance. Keywords : mineral-amino acid complex ( AvailaZn,Mn,Cu,Fe and AvailaSe); white shrimp; growth performance; immunity; drip loss
