其他摘要：Perna viridis (Green Mussel) and P. indica (Brown Mussel) of the family Mytilidae are the most common marine mussels observed in Indian waters. The materials for the present study was collected by hand picking from Sippighat, a sea water logged area where the water levels are highly influenced by the tidal levels. The specimen was sorted out into three different size groups viz. small (61.52-80), medium (80.03-99.94) and large (100-154.08).The species was identified and confirmed as Perna indica by position of the posterior muscle scars along with the external morphological characters differentiated P. indica from P. viridis. Biometric analysis showed that width is getting decreased from the small size groups to the large size groups, which means the length wise growth increases when the individuals get older. Similarly, thickness also gets decreased from the small size groups to the large size groups. Total weight, meat weight and shell weight ratios shows an increasing order from the small size groups along the medium size group to the large size groups. The protein percentage is also high with values near to 12% and females are having a slightly higher percentage of protein compared to that of males. Carbohydrate and lipid value is found to be comparatively less but carbohydrate percentage was found to be slightly more in the case of females. The lipid value is constant in both male and females. The abundance of P. indica was very minimal and shows little distribution in the Bay Island. So it is recommended that further studies may be conducted on the distribution and conservation of this resource for future utilization in the Andaman and Nicobar group of islands.KEY WORD: Perna indica, Biometrics, Proximate composition, Andaman Islands.
