A Comprehensive Overview on the Biology and Culture Practices of Mud Crab (Scylla Sp.) in India

Abstract

The genus Scylla, commonly known as mud crabs, is frequently found in mangrove habitats, brackish waters, coastal regions, ponds, and intertidal swamps, making them a rapidly growing exportable resource in India. Farming mud crabs serves as a vital income stream for fish farmers throughout the country. The increasing demand for mud crabs in the export market as an alternative to shrimp has led to heightened collection of wild seeds for cultivation, thereby posing a threat to natural populations. To promote sustainable crab farming and alleviate pressure on wild stocks, it is essential to focus on the availability of seeds, which is a crucial factor for successful farming. Additionally, crab fattening proves to be lucrative due to its quick turnover and high survival rates. This practice is particularly advantageous for small-scale operations, providing an extra source of income for local fishermen. This review article aims to consolidate existing knowledge on the ecology and biology of mud crabs.
