The giant gourami (Osphronemus goramy) is a leading freshwater fish species in the aquaculture of South-east Asia, valued for its adaptability and potential for selective breeding. However, the lack of systematically assembled superior varieties has limited its productivity and economic optimization. With an integrated perspective on the technological advances and agribusiness dimensions of developing high-performing strains of the giant gourami species, this book provides an in-depth reference guide to selective breeding approaches, innovations in hatchery and grow-out technologies, and sustainable management strategies tailored to tropical aquaculture systems. It also provides a forward-looking analysis of market dynamics, disease management and forecasting methods for production growth. Additionally, the book:· Serves as a comprehensive reference text for giant gourami production and breeding in freshwater aquaculture across developing regions.· Focuses on a commercially important yet under-represented aquaculture species with a strong relevance for sustainable small- and medium-scale farming systems.· Draws on the field experience of long-term breeding programs in Indonesia to bridge the gap between science, technology and industry. By combining applied research results, practical methods and policy insights, the book is a comprehensive reference guide for researchers, students, practitioners, policy makers, breeders and aquaculture entrepreneurs, committed to advancing the future of giant gourami production.
