Assessment of Population Structure and Seasonal Variation in Barytelphusaguerini in Rivers of Marathwada, Maharashtra, India

Abstract

Freshwater crabs constitute one of the largest group of invertebrates occupying the Indian peninsula waters. The past few decades have seen an upsurge of interest in the using freshwater crabs as an ecological model for assessing impact of various environmental stress and pollutant in the rivers. The present investigation deals with the study of distribution of the species, identify specific habitat requirements, depict population levels, trends and recognize detailed risks to significant and exceptional freshwater crab.

The study included the traits in the life of the crab, body size and abundance, relative abundance, sexual ratio, distribution in relation with time during the year and size distribution, maturity of the crab Barytelphusaguerini. The body size and sexual maturity differed between the localities of sampling sites.)
