Nutritional susceptibility to morphological, chemical and microbial variability: An investigation on mud crab, Scylla serrata in Bangladesh


Author(s): Bijoya Paul, Md. Hasan Faruque, Roland Nathan Mandal, Dewan Ali Ahsan

Abstract: Nutritional susceptibility of Scylla serrata to chemical and microbial variability with varying morphological capacity was the thematic area of the present investigation. In detail, morphological capacity considering carapace length, carapace width, total length, chelate leg length and crawl leg length; the nutritional composition considering protein, lipid, ash, moisture; chemical assessment considering TVN, TMA; and microbial assessment considering TBC, TMC were measured for both male and female mud crab. Morphological observation revealed that the weight of male mud crab was changed by 65% with changing per unit of length (b=0.65) and in female it was by 42%. Moreover, for males the b values of weight-condition factor and length-condition factor ranges from above 2 to above 3; whereas in females the range of values were less than that found in males. TBC and TMC found in muscle of male mud crab were higher than that of female. The beta co-efficient of multivariate regression analysis showed (TVN= 9.2+0.48 TMA+0.02 TBC+ 1.7 TMC) that the TVN is changed by 0.48 unit/TMA, 0.02 unit/TBC and 1.7 unit/TMC changes indicating that the TVN value is highly changed with changing TMC followed by TMA and TBC. In case of TMA, the beta co-efficient of multivariate regression analysis (TMA=52.859+ 0.032TBC+3.624TMC) showed that the TMA is changed by 0.032 unit/TBC and 3.624 unit/TMC changes indicating that the TMA value is highly changed with changing TMC rather than that of TBC. The protein content found to negatively relate with the moisture content by 0.661 co-efficient values and with lipid with 0.04 values. The correlation co-efficient of proximity composition considering primarily protein and lipid with chemical and microbial variability showed that protein is negatively sensitive to TVN, TBC and TMC values. It can then be inferred that the nutritious proximity of mud crab is significantly susceptible to sex with varying morphological capacity, chemical and microbial variability.
