Feed is one of the factors that affect the success of hatchery culture of mud crab (Scylla olivacea). The use of artificial feed in the form of microdiet can ensure availability, lower production costs and higher flexibility than natural feed. During this time the artificial feed used is a commercial feed, which is relatively expensive, therefore the need for research to produce artificial feed of good quality, with a cheap price.. The objective of this research is to determine the combination of raw material of artificial feed protein which produce dissolved protein content, protein hydrolysis degree and best protein content of feed. The experimental design used was completely randomized with eight treatments and three replications. The treatments were the use of various combinations of feed protein ingredients : A) 100% Artemia flour, B) 100% fish meal, C) 100% squid meal, D) 50% Artemia and 50% fish meals, E) 50% Artemia and 50% squid meals, F) 50% fish and 50% squid meals, G) 35% fish, 35% squid and 30% Artemia meals, H) commercial feed. The parameters used were dissolved protein content, protein hydrolysis degree and protein feed content. The results showed that the difference of feed protein raw materials had significant effect (p <0,05) on soluble protein content and feed protein hydrolysis degree. The highest content of soluble protein in in the diet with a protein raw material was squid meal, but not significantly different (P> 0,05) than Artemia meal and combination between 50% Artemia and 50% squid meals, but significantly different (P < 0.05) than other treatments. The highest degree of protein hydrolysis in the diet with a protein raw materials was Artemia meal, but not significantly different (P> 0.05) than in commercial feed as well as combination between Artemia and squid meal (P> 0.05), but significantly different (P <0, 05) compared to other treatments. Feed protein content according to the needs of mangrove crab larvae. Fat content with a protein raw materials was 100% artemia meal was higher than the need. Carbohydrate content with a protein raw materials were 100% artemia meal, a combination of 50% artemia meal and 50% squid meal and commercial feed according to the needs of mud crab larvae

Artificial feed is an alternative media applications spinach extract (EB) that is known to contain molting stimulant. However, utilization of the artificial feed is related to its expensive cost, with a very high protein concentration since it's mainly produced from fish based materials, so need to be studied artificial feed formulation with substitution of vegetable material in stimulating molting and growth of mud crabs. Four formula artificial feed enriched EB (700 ng/g crab) used in this study were feed A (fish, crab shells, and cassava), feed B (fish, silage, shell crab, and cassava), feed C (fish, silage, shell crab, soy flour, and cassava), and feed D (fish, silage, shell crab, soy flour, corn starch, and pollard), trash fish and feed A without EB as control. During the test, mud crab intermolt phase was culture individually in crab box placed in pond. The results showed that the percentage of molting and weight growth in their respective in the feed A (44% and 41.96%); feed B (56% and 31.57%); feed C (74% and 23.20%); feed D (50% and 39.15%); trash feed control (24% and 50.66%); and feed A without EB (28% and 35.11%). An opposite phenomenon, where the feed C with the highest percentage of molting but with the lowest growth rate, the opposite occurs in the control of trash feed. This is apparently the effect of spinach extract as a stimulant molting, where performance can be optimized with a complete and balance nutrient composition. This prediction is supported by the analysis of protein content of crabs tested at the highest feed C treatment compared with the control feed. Key words: spinach extract, soft shell crab, molting, artificial feed, growth ABSTRAK Pakan buatan merupakan alternatif media aplikasi ekstrak bayam (EB) yang diketahui mengandung stimulan molting. Namun demikian, pakan buatan yang digunakan masih mahal dengan kandungan protein yang tinggi, karena berbahan dasar ikan, sehingga perlu dikaji formulasi pakan buatan dengan subtitusi berbagai bahan nabati dalam menstimulasi molting dan pertumbuhan kepiting bakau. Empat formula pakan buatan yang diperkaya EB (700 ng/g kepiting) digunakan pada penelitan ini, yaitu Pakan A (ikan, cangkang kepiting, dan ubi), Pakan B (ikan, silase, cangkang kepiting, dan ubi), Pakan C (ikan, silase, cangkang kepiting, tepung kedelai, dan ubi), dan Pakan D (ikan, silase, cangkang kepiting, tepung kedelai, tepung jagung, dan pollard). Pakan rucah dan pakan A tanpa EB digunakan sebagai kontrol. Selama penelitian, kepiting bakau fase intermolt dipelihara secara individu dalam crab box yang diletakkan di tambak. Hasil penelitian menunjukkan persentase molting dan pertumbuhan bobot masing-masing pada Pakan A (44% dan 41,96%); Pakan B (56% dan 31,57%); Pakan C (74% dan 23,20%); Pakan D (50% dan 39,15%); kontrol pakan rucah (24% dan 50,66%); dan pakan A tanpa EB (28% dan 35,11%). Terjadi anomali, yaitu Pakan C dengan persentase molting tertinggi, tetapi dengan tingkat pertumbuhan terendah, namun terjadi sebaliknya pada kontrol pakan rucah. Hal ini diduga efek dari ekstrak bayam sebagai stimulan molting, dimana kinerjanya dapat dioptimumkan dengan komposisi nutrien lengkap dan seimbang. Pendugaan ini didukung hasil analisis kadar protein kepiting uji pada perlakuan Pakan C tertinggi dibandingkan kontrol.

Vitomolt is a molting stimulant made from spinach (Amaranthus spp.) extracts. The objective of this study was to optimize the dose of vitomolt injection on the growth and molting of mud crab (Scylla spp). The research was conducted in April to June 2010. There were three doses of vitomolt tested, i.e. 9 mg/g crab, 15 mg/g, and 21 mg/g crab. The results showed that the dose of vitomolt injection had great influence on the growth and molting of mud crab. Higher dose of vitomolt gave higher growth but its molting percentage was different. Vitomolt dose of 15 mg/g crab was the optimal dose to induce molting of mud crab while the dose of 21 mg/g crab gave the highest growth which reached 53.6%. However, in terms of productivity, dose of 15 mg/g crab gave the highest production of soft crab. Key words: dose, vitomolt, growth, molting, mud crab ABSTRAK Vitomolt adalah stimulan molting yang terbuat dari ekstrak bayam (Amaranthus spp.).

Efforts to cultivate bileh fish (Rasbora maninjau) experience obstacles in providing seeds due to controlled reproduction in aquaculture containers is still difficult to do. This is due to the slow maturation of fish gonads, which takes a long time. Internal factors, including the hormonal system, influence the reproductive cycle and maturation of fish gonads. This study aims to determine the effect of PMSG (Oodev) hormone administration through feed on the reproductive performance of bileh fish. Experimental research method with CRD experimental design (completely randomized design). The experiment consisted of 4 treatments (P) with three replications. The treatments were PMSG hormone (Oodev) with different doses, namely 0 (P1), 0.5 (P2), 1 (P3), and 2 ml/kg feed (P4). The research phase included the preparation of containers and fish, preparing hormones and feed, rearing, and data collection. Parameters taken and evaluated include gonadosomatic index (GSI), hepatosomatic index (HSI), estradiol concentration, fecundity, and egg diameter. Data were processed and analyzed using statistics (Anova). The results showed that the administration of PMSG hormone (Oodev) through feed had a significant effect on GSI, HSI, estradiol concentration, fecundity, and egg diameter (P0.05). The best treatment was P3 (1 ml/kg) with a GSI value of 8.25%, HSI of 0.41%, estradiol level of 22.46pg/mL, fecundity of 3207 eggs, and egg diameter of 0.85mm.Keywords:PMSGOodevPerformanceReproductionBileh fish

Feed eficiency is largely determined by its availability in suficient quantities and on timefeeding, s o it is necessary to study the frequency of feeding for the best production of soft shell crab. Four feeding frequency (1 time per day, 1 time per 2 days, 1 time per 3 days, and 1 time per 4 days) tested in this study. Feed with nutrient composition of 30.86% protein, 7.2% fat, nitrogen free extract (NFE) 48.89%, crude fiber 5.7% enriched with vitomolt 0.1041 5 mg/g of feed to the standard dose and 0.4166 mg vitomolt/g feed to high doses; or equal to 700 ng vitomolt/g crab. Test crabsof Scylla sp. reared in crabs box and placed in the pond. The results showed the frequency of feeding 1 time per 2 days resulted in the highest percentage of molting (66.67%) and the lowest percentage of moulting was found at 1 per 4 times a day of feeding (36.67%). Growth param eters such as weight and carapace width, and feed eficiency did not difer among all treatments. Thus, feeding in the soft shell crab for the maximum production can be done with a frequency of 1 time per 2 days .

In the rearing of fish larvae, artificial feed can be given when digestive enzymes have been produced. To improve the ability of fish larvae to utilize artificial feeds can be done with the addition of exogenous enzyme into the artificial feeds. The aim of this study was to determine the dose of papain enzyme and the correct predigest artificial feeding stadium on metamorphosis rate and glycogen content of mangrove larvae (Scylla olivacea). The experimental design used was a factorial pattern with a complete randomized baseline design, the first factor being the dose of papain enzyme (0%, 1.5%, 3.0% and 4.5%), while the second factor was the predigest artificial feeding stage (zoea 2 and 3). The results showed that the difference of dose of papain enzyme and predigest artificial feeding stages had significant effect (p <0.05) on the metamorphosis rate of 7, 9, 10, 12, 13, 16 and 17 day larvae, but the interaction between them was not significant (p>0,05). The rate of metamorphosis at doses of enzyme papain was 0% and 1.5% longer and significantly different (p <0.05) compared to 3% and 4.5% doses. The rate of metamorphosis at doses of 3.0% and 4.5% was not significantly different (p> 0.05). The content of glycogen larvae in dose of enzyme papain 4,5% not different than dose 1,5% and 3,0% but higher and significantly different than dose 0%. Glycogen content at dose 0%, 1,5% and 3,0%. was not significantly different (p> 0.05). Based on the results of these studies to hydrolyze feed proteins can be used papain enzyme with a dose of 4.5%.Keywords: papain enzyme, metamorphosis rate, mangrove crab larvae (Scylla olivacea), glycogen content

This study aims to study the performance of phytoecdisteroids from mulberry leaves in molting stimulating of mangrove crabs. The research was carried out at the Research and Development Center for Aquaculture at the Faculty of Marine Sciences and Fisheries at Hasanuddin University, located in Bojo Village, Mallusetasi District, Barru Regency, South Sulawesi Province. Mangrove crabs (Scylla olivacea) weighing 45-55 g and carapace widths 60-65 mm were used as test animals. There were five doses of mulberry leaf extract applied through feed, namely: A) 1.1 mg / g feed, B) 1.9 mg / g feed, C) 2.7 mg / g feed, D) 3.5 mg / g feed. Crabs were kept individually in plastic boxes that are floated above the surface of the pond. During rearing, crabs are fed 3% dry fish per day which has been enriched with mulberry leaf extract. The parameters observed were ecdysteroid compounds contained in mulberry leaf extract, ecdysteroid content in hemolymph before and after application of mulberry leaf extract, and molting percentage. Identification of the ekdisteroid compounds contained in mulberry leaf extract was carried out using Thin Layer Chromatography (TLC) and Measurement of the content of ecdysteroids in crab hemolymh was carried out using Ultra Fast Liquid Chromatography (UFLC). The results showed that the 3.5 mg dose of mulberry leaf extract / g feed gave the highest increase in ecdysteroid hemolymph, which was approximately 1760 ekdisteroid per mL hemolimph, while the dose of 1.1 mg / g feed only provided an increase of 100 ng ekdisteroid per mL hemolymph. The higher the dose of mulberry leaf extract in the feed, the higher the increase in the concentration of hemolymph ecdysteroids, but the high concentration of ecdystoid in the hemolymph does not guarantee molting. The optimal dose of mulberry leaf extract in the feed stimulating molting was 2.4 mg / g of feed.Keywords: mulberry, phytoecdysteroid, molting, crab, aquaculture

The first step to establishing appropriate broodstock management and conservation programs and to avoid decreasing genetic variability in this selective breeding program is the development of molecular genetic markers that can be used for evaluation of genetic stock determinations in gene flow rates. However, morphologically it is rather difficult to distinguish between one individual and another. The purpose of this study was to analyze genetic variation to prove differences in intrapopulated crabs. Small crab samples were collected from the district. Kaimana, West Papua. Morphological analysis was carried out by looking at differences in the color and pattern of white spots between one individual and another. The isolation of the crab CO1 gene was carried out by analyzing each individual after grouping it based on morphology. The results of the morphological analysis showed that males had seven color patterns and white carapace patterns while females had five color patterns and white spots on the carapace. However, there is little difference between morphology and genetics, especially in females, where the female is genetically divided into only two major groups. This indicates that there is information on phylogenetic relationships between individuals. The white spot on the carapace is genetically influenced so that it can be used to identify species or varieties, while the carapace color has not been shown to be influenced by the CO1 gene.
