Abstract

Lamellidens marginalis  (Lamarck, 1819) is one of the important candidate species for freshwater pearl production in India. In the present study, the length-weight, width-weight and height-weight relationships of L. marginalis maintained in the farm were examined from January 2015 to September 2016. Monthly sampling was carried out and a total of 1015 specimens were analysed for the study. The length-weight, width-weight and height-weight relationships derived were W = 0.0003L2.712, W = 0.0018L2.708 and W = 0.0.0293L2.210 and the value of r2 was estimated as 0.776, 0.619 and 0.597 respectively. The values of  b indicated the relative growth in body weight and superior physiological condition of the mussel. The length-weight, width-weight and height-weight relationships  were found to be positive allometric and better correlation was observed in length-weight and width-weight relationships.
