The objective of the research was to determine the best enrichment of rotifer and the naupli of Artemia as feed for mud crab, S. paramamosain larvae, also to know their increasing of the DHA/EPA ratio and vitamin C content. Four treatments were tested, namely : A) Mud crab larvae every two days were given rotifer and naupli of Artemia enriched with HUFA and vitamin C also added RICA-1 probiotic at 2 mg/L, B) Mud crab larvae every two days were given rotifer and naupli of Artemia enriched with HUFA and vitamin C, C). Mud crab larvae every two days were given rotifer and naupli of Artemia enriched with vitamin C, and D). Mud crab larvae every three days were given rotifer and naupli of Artemia enriched with vitamin C. Result showed that the crablet production from the highest to the lowest was as follows: treatment A (177.5+17.6 ind./tank), treatment B (160+14.1 ind./tank) (A and B showed no significant different results (P>0.05)), treatment C (136+5.6 ind./tank), and treatment D (106+8,5 ind./tank) (C and D results indicated a significantly different (P<0.05) with treatment A). Higher level of DHA/EPA ratio of 69.23% was found on rotifer enriched with HUFA, while on naupliofArtemia only 28,72%. Higher level content of vitamin C was 50.56% in rotifer enriched with vitamin C, while in naupli of Artemia was only increase to 35.56%.Keywords: Scylla paramamosain larvae, enrichment, HUFA, vitamin C, crablet

Feeding Regimes

The study evaluated the effects of extended dietary inclusions of rotifers (Brachionus plicatilis) on the survival, metamorphosis rate, growth and development time in the larvae of mud crabs (Scylla paramamosain). The five most commonly published feeding regimes of mud crab (S. paramamosain) larvae were selected and tested by including rotifers onto them. Mud crab larvae in the first feeding regime were fed exclusively with Artemia nauplii (control or regime A), while those in feeding regimes 2, 3, 4 and 5 were fed rotifers starting from zoea 1 (Z1) to various development stages of mud crab larvae whereas feeding with Artemia nauplii was commenced from the Z2 stage until the end of the trial (megalopa stage). The results of the larval feeding trial for 24 days of culture showed the progressive decrease in survival of the larvae in all feeding regimes. Extended inclusion of rotifer feeding until Z5 stage resulted in significantly higher survival than in the control from 18 day after hatching onwards. Larval survival was negatively correlated (R2 from 0.78 to 0.90) with the rearing time; however, different feeding regimes had no significant effect on this correlation. Extending inclusion of rotifer feeding until the Z3, Z4 and Z5 stages resulted in higher percentages of megalopa metamorphosis than in regime control, but did not significantly impact development time, carapace width, body length and wet weight of megalopa.

Improvement of feed quality for mangrove crab larvae rearing is one of theimportant factors to increase of crablet production. The aim of the research was to knowthe influenzing of enriched Artemia nauplii using Nannochloropsis sp fed to the differentstages of larvae Scylla olivacea on crablet production. Twelve units of tanks volume 250L filled with saline water salinity 30 ppt, aerated, then stocked with new hatched mud crablarvae zoea-1 at the density 100 ind./L. The larvae zoea-1 were fed rotifer, Brachionus sp.and after zoea-3, beside fed by rotifer, the larvae were also fed by Artemia naupli. Fourtreatments were tested, namely: A). Artemia nauplii enriched using Nannochloropsis sp.was given to the larvae zoea-3 until develop to megalop stage. B). Artemia nauplii enrichedusing Nannochloropsis sp was given to the larvae zoea-4 until develop to megalop stage.C). Artemia nauplii enriched using Nannochloropsis sp was given to the larvae zoea-5 stageuntil develop to megalop stage. D). Artemia nauplii without enriched using Nannochloropsissp. was given to the larvae zoea-3 until develop to megalop stage. Result of the researchshowed that the highest of Larvae Development Indexes and Megalop Occurence Indexeswas obtained in treatment A and resulted the highest of crablet production, then followed bytreatment C and B and those were significantly different (P<0.05) with the crablet productionin treatment D. The use of Artemia nauplii enriched by Nannochloropsis sp. to feed larvae,S. olivacea stage zoea-3 to zoea-5 until develop to the megalop stage is one of the key factorto enhance the crablet production. By this finding, the crablet production in hatchery will beincreased and the mud crab culture in brackishwater pond able to developed.
