Diatoms in Sustainable Aquaculture

This book presents an integrative perspective on the role of diatoms in advancing sustainable and
productive aquaculture systems. The initial chapters explore trophic coupling and ecological dynamics
between diatoms and zooplankton, followed by emerging innovations in biofloc technology
and recirculating aquaculture systems (RAS) that harness diatoms for water quality improvement
and nutrient recycling. The chapters further examine the nutraceutical and aquafeed potential of
diatoms, their polyunsaturated aldehydes (PUAs), and their impact on fish embryonic development
and larval productivity. Further, the volume covers microbial interactions, diatom-based biocontrol
strategies, and nanotechnology applications in aquaculture health. The book also highlights sustainable
circular economy approaches via diatom biorefinery, the use of AI and genetic engineering in
fish health monitoring, and the role of precision aquaculture in climate resilience.

Key Features:

• Provides a comprehensive systems ecology perspective on diatom–zooplankton interactions and their role in aquaculture.
• Discusses the application of biofloc and RAS technologies using diatoms for nutrient management and wastewater remediation.
• Explores the aquafeed and nutraceutical potential of diatoms for enhancing larval fish productivity and health.
• Examines diatom-derived PUAs, microbial interactions, and nanotechnology-enabled drug delivery in aquaculture.
• Highlights climate-smart aquaculture, circular economy frameworks, and AI-driven fish health diagnostics.

This book is an essential resource for researchers and students of marine biology, environmental
science, and biotechnology.
