Studies On Diversity of Freshwater Crabs (Decapoda: Parathelphusidea: Potamonautes) Collected from in and Around Paddy Field of Cuddalore District, Tamil Nadu, India
Subject area: Physical Sciences and Environment · Area of research: Diversity
Abstract
Freshwater ecosystem has an endemic flora and fauna together with freshwater crabs. They are ecologically and medically indispensable macro-invertebrates. This is the first study aimed at contributing to the documentation and conservation of freshwater crabs in southeast India of oriental region. Paddy field of Cuddalore district of Tamil Nadu, during the period from October 2024 to March 2025 with a view to assess the status of freshwater crab resources in the area. The study was made on species diversity, habits and habitat, distribution and economic importance of Brachyuran crabs are very meagre the present study was undertaken. During the last decades, knowledge on biodiversity of freshwater decapods has increased considerably. The study involved investigation of species diversity and distribution. The present communication recorded 10 species of freshwater crabs belonging to 4 genera and 2 families. During collection the ?pregnant female and juveniles? were released back into the same field for conservation purpose.
Keywords
