Abstract

Freshwater decapod crustaceans represent economically vital components of aquatic ecosystems worldwide, yet their populations face unprecedented threats from anthropogenic pressures including habitat degradation, pollution, and climate change. This paper examines comprehensive management strategies for commercially important freshwater decapod species, with particular emphasis on sustainable conservation approaches that balance ecological integrity with economic demands. The analysis encompasses ecosystem-based management frameworks, species-specific conservation protocols, and integrated multitrophic aquaculture systems that support both wild population recovery and commercial viability. Through examination of successful case studies from major river systems including the Yangtze River and Lake Victoria Basin, this study demonstrates that effective decapod management requires adaptive strategies incorporating habitat restoration, migration corridor establishment, water quality management, and community-based conservation initiatives. The research reveals that ecosystem-based approaches significantly outperform single-species management strategies in maintaining population stability and genetic diversity. Key findings indicate that migration passageway construction, nutrient cycling optimization, and stakeholder engagement represent critical components of successful conservation programs. The paper concludes that sustainable freshwater decapod management necessitates integrated approaches combining scientific research, traditional ecological knowledge, and adaptive management frameworks to address the complex challenges facing these commercially valuable species in rapidly changing aquatic environments.
