Abstract

Recirculating aquaculture systems (RAS) have gained prominence in European countries, primarily for farming salmon and trout. However, in Asia, particularly in China, RAS farms have expanded to include seabass, hybrid grouper, turbot, and other species. While Malaysia embarked on RAS farming as early as 2008, it remains in its nascent stages. In contrast, Singapore has accelerated its RAS efforts, driven by food security concerns during the COVID-19 pandemic.

Yet, successful RAS development extends beyond equipment alone. A holistic approach is essential, encompassing various critical areas such as broodstock management, hatchery technology (Green House Mesocosm), optimized RAS design factors including culture tank design, optimized flow rate, solids waste removal rate, CO₂ degassing rate, sizing of bio-treatment for nursery (disease free fingerlings); grow-out, as well as product marketing (taste) and quality assurance.

These areas should also be integrated with artificial intelligence (AI) for an optimization along the development. Hybrid grouper Epinephelus fuscoguttatus ♀ x Epinephelus lanceolatus ♂ would be the focus species for Southeast Asian RAS players. The presentation will discuss some aspects in RAS for the fingerling and grow-out production of a hybrid grouper.
