Climate – Smart hatchery management offers a comprehensive and transformative framework for enhancing aquaculture resilience under a rapidly changing climate. By addressing stage-specific vulnerabilities such as thermal stress, hypoxia, acidification, and pathogen exposure through innovations in breeding, larval rearing, disease control, and operational management, hatcheries can maintain high-quality, robust seed production. Adaptive breeding strategies, including selective breeding, temperature-adaptive broodstock selection, genomic selection, and gene editing, enable the development of heat-, salinity-, and disease-tolerant strains. Complementary interventions in larval rearing precision environmental control, biofloc and green water systems, microbiome modulation, and optimized nutrition enhance survival, growth, and stress resilience.
Integrated disease management, combining vaccination, immunostimulants, early digital diagnostics, and biosecurity, mitigates climate-driven pathogen risks, while renewable energy adoption and low-carbon operational strategies reduce environmental footprints and operational costs. Efficient water use, nutrient recycling, environmental monitoring, and ecosystem-based hatchery siting further strengthen ecological sustainability.
Collectively, these approaches create a holistic, climate-smart hatchery model that is technologically advanced, environmentally responsible, and resilient to climate variability. Implementing these strategies at scale will be essential to secure sustainable aquaculture production, safeguard food security, and support livelihoods in regions increasingly affected by climate change.BOOK CHAPTERS 2026 READY.docx 13
