“…), sedangkan perairan dengan kisaran pH 7,50 -9 di kategorikan sangat baik untuk pertumbuhan kepiting bakau (Christensen et al, 2005;Romano and Zeng, 2007;Shelley and Lovatelli, 2011). Yunus et al (1997) menyatakan bahwa berdasarkan hasil uji laboratorium, tingkat pH berperan terhadap sintasan larva kepiting bakau Scylla serrata, tingkat sintasan paling tinggi tedapat pada kisaran pH 9,1-9,5. Dengan demikian kandungan pH perairan mangrove Teluk Bintan mendukung pertumbuhan kepiting bakau baik pada tahap juvenil, muda maupun dewasa, tetapi kurang optimal bagi perkembangan pada tahap larva.…”

Mud crab (Scylla serrata) is one of small scale fisheries commodity that have high economic value and typically associated with good mangrove ecosystem. A habitat degradation will cause a serious impact on the existence of mud crab population. The puropse of this study was to assess the ecological quality of mud crab habitat condition on Bintan Bay’s mangrove ecosystem. Ecological data collection was conducted by using plots line transect for mangrove and the mud carb data collection by using fishermen catch (fisher based survey). The results showed the value of habitat quality index (HQI) of mud crab (Scylla serrata) ranged from 52-82 which mean in the “moderate” category (index value 43-66) and "good" (index value 67-90). It showed that Bintan Bay’s mangrove ecosystems was good enough to support the viability of mud crab. Habitat quality had a linier impact on body weight gain (R2 = 99.78%) and carapace width (R2= 99.21%). This showed that higher the index value of habitat quality, the size of the body weight and carapace width will increases.

“…To minimize an overexploitation, the mangrove crab culture in the brackishwater pond where the seed from hatchery could be developed. Earlier research on mangrove crab seed production was reported in some countries such as Taiwan (Chen and Cheng, 1985); Phillipphina (Quinitio et al, 2001); Japan (Hamasaki et al, 2002), Malaysia (Anuar et al, 2011) and Indonesia (Yunus et al, 1997).…”

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.

Studies on bio-ecosystems sustainability and feasibility are urgent because many mangrove ecosystems have been converted into ponds as a source of livelihood. This study aimed to evaluate the sustainability level of the mangrove bio-ecosystem in Dabong Village and formulate the most appropriate strategy in silvofishery development. The method used was a field survey to obtain secondary and primary data. Bio-ecosystem feasibility analysis was carried out descriptively, qualitatively and quantitatively based on data compilation of water quality, soil fertility, macrozoobenthos and mangrove density. SWOT analysis was used in developing the strategies. Based on the study results, the land suitability matrix for silvofishery development in Dabong Village had a very suitable category (69.00%) regarding soil value conditions and water quality. The abundance of macrozoobenthos was 21 individual m2 -1 gatropoda, 30 individuals m2 -1 bivalves, and eight individuals m2 -1 crustaceans. Stand density values of Rhizophora apiculata, Avicennia alba, and Sonneratia alba ranged from 15-25 individuals m2 -1, 18-27 individuals m2 -1, and 14-24 individuals m2 -1, respectively. According to ecosystem characteristics, the strategy for using mangroves in the research site was to increase the bio-ecosystem strength and minimize the damage or degradation risks as a threat to the impact of mangrove ecosystem utilization using the silvofishery model. Its application could be an alternative for sustainable use of the mangrove ecosystem.
