Comparetive study of length-weight relationship of Parreysia corrugata (MULLER), AND Lamellidens marginalis (Lamark), from nanded region, Maharashtra (India)

Comparative study of length - weight relationship of fresh water mussels, Parreysia corrugate and Lamellidens marginalis is the important aspects of biological study of both. The length and weight is having mathematical relationship in between them. If one factor is known the other may be estimated from it and vice versa. For the study 241 specimen of Parreysia corrugate and 169 specimen of Lamellidens marginalis were collected from Naigaon tank, Nanded region, and kept in laboratory for acclimatization. length and weight relationship of both the species was estimated by using Cube-Law.
