The Tilapia Industry— Challenges, Prospects, and Research Initiatives Worldwide and in the Philippines: A Review

Abstract

Tilapia is a globally significant aquaculture species, ranking third in total production volume worldwide and second among cultured species in the Philippines. Cultivated in over 150 countries, its wide adaptability and economic importance are underscored in diverse production systems. Commonly referred to as the “aquatic chicken”, tilapia is characterized by rapid growth, broad environmental tolerance, relative disease resistance, highre productive capacity, and efficient utilization of both natural and formulated feeds. This paper reviews and assesses the industry’s challenges, prospects, and research initiatives essential for its sustainable development. The review analysis shows that tilapia aquaculture is expanding in response to rising global demand and market diversification, driven by technological innovations in genetics, water management, digital monitoring, and disease control that enhance production efficiency and system resilience. Nevertheless, productivity is still limited by low survival rates of fry and fingerlings, genetic deterioration of broodstock, disease outbreaks, increasing production costs, and environmental stressors, with disproportionate impacts on small and medium-scale producers. Recent scientific developments, including improved and salt-tolerant strains, sex-control and gene-editing technologies, recirculating and biofloc production systems, vaccine development, rapid diagnostic tools, and alternative feed formulations, offer substantial potential to address these constraints and advance the sustainability of tilapia aquaculture systems. Overall, rising global demand, expanding markets, and continued technological and research-driven innovations position tilapia aquaculture for sustained growth, provided that persistent production, disease, and environmental challenges are addressed through integrated and sustainable approaches. Accordingly, integrated and coordinated investments in genetic improvement, resource-efficient production systems, disease prevention and health management, alternative feed development, and capacity building are critical to improving productivity, resilience, and long-term sustainability of the tilapia aquaculture sector.
