ABSTRACT
Mussels play a significant role in marine benthic ecological construction because they accumulate into beds, changing the nature and intricacy of the bottom. Population structure and length-weight relationships of two mussels (Anadara granosa and Meretrix lamarckii) in the Bay of Bengal, Bangladesh were investigated based on occasional data from January to December 2020. Samples were collected from the sampling sites (Sathkhira and Cox’sBazar) with the help of laborer in the presence of Principal investigator and research assistant. This study also revealed the maximum recorded length of A. granosa and first report of M. lamarckii from the worldwide water bodies. We observed maximum length of A. granosa was 7.50 cm (maximum recorded length) and 6.83 cm for M. lamarckii. Allometric coefficient (b) value was 2.61 and 2.83 for A. granosa and M. lamarckii, respectively that indicating the growth was negative allometric for both species. This study would be helpful for the fisheries researcher and biologist to conserve and sustainable management of these species.
