The biochemical composition (proteins, lipid, ash and moisture) of different parts of the body (gill, meat, egg) of fattened and natural mud crab Scylla serrata was determined. Twenty four samples of S. serrata (12 from wild & 12 from fattening farm) of different sizes and sexes (half of the sample is male) were used in this study. The mean protein and lipid contents are significantly (p<0.05) higher in fattened crabs than natural in natural crabs regardless of size and sexes. Moisture and ash were higher in natural crab than in fattened ones. The highest and lowest moisture content was noticed in gills and eggs in both natural and fattened crabs. Protein and lipid contents were comparatively higher in eggs than in other body parts. Female crabs contained high protein and lipid than males in both natural and fattened crabs. From the results of this study it may considered that fattened crab might be comparatively superior to natural crabs as they appear to provide higher levels of protein and fat for human nutrition.

Abstract The aim of this study to find out the optimal level of salinity for the growth and survival of the mud crab (Scylla serrata). The weight of crab seeds were about 47.65-51.32 grams and the carapace length ranged from 64.35-71.30 mm, then put into 12 tanks (1 m x 1 m x 0.4 m) with a density of 4 crab seed per tank. During the maintenance of this test, mangrove crab was fed with fresh chicken intestines as much as 10% of its body weight per day. Water changes are carried out more than 150% per week. At the beginning of the experiment, each tank was conditioned to the same water salinity in all experimental units, namely 33 ppt. To see the effect of differences in salinity levels on the growth and survival of mud crabs, 4 treatments were made consisting of (A) 33 ppt salt content, (B) 31 ppt salt content, (C). The salt content is 29 ppt, and (D) the salt content is 27 ppt. From the results of this experiment, it is known that a decrease in the salt content of 4 ppt is the best treatment for the growth of mud crabs, but has no effect on the survival value.

For the first time, a mollicute-like organism (MLO) was cultured from moribund mud crabs (Scylla serrata) during an outbreak of clearwater disease in Zhejiang Province, China. The MLO displayed a fried-egg colony morphology in culture, did not possess a cell wall, and was not retained by 0.45 μm and 0.2 μm filters. It was able to ferment glucose, sucrose, lactose, and maltose, but it did not utilize arginine and urea. The MLO grew in the absence of bovine serum and was not susceptible to digitonin. Sequence analysis of the 16S rRNA gene revealed that this MLO had 99% identity withAcholeplasma laidlawiiPG-8A, which indicates that the organism isolated from mud crabs is a member of the genusAcholeplasma.

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.

Awareness of Mud Crab over exploitation in Mangkang Wetan Waters has been noticed. One of the reference information is the growth study to determine the condition of the mud crab population. High demand encourages the fisherman to catch more, which leads to overexploitation in nature. The study aimed to estimate the growth, mortality, and exploitation rate of mud crabs. The 921 mud crabs samples were collected from Mangkang Wetan Waters from October 2018 to January 2019. The method used was the survey method. The crabs were taken once a week for 4 months. The width and weight of crab carapace were measured. The growth rate of S. serrata was 0.93/year (male) and 0.69/year (female). The natural mortality rate of S. serrata was 1.08/year (male) and 0.89/year (female), the mortality of catch (F) was 0.55/year (male) and 1.09/year (female). The rate of exploitation of male S. serrata reached 34%, and the rate of exploitation of female S. serrata was 55%. The exploitation of female S. serrata shows that overexploitation has occurred because the optimum value of exploitation (E-OPTIMUM) is equivalent to E=50%.
