Khoo Jia-Zin
Managing Director
Sepang Today Aquaculture Centre Sdn Bhd

Jia-Zin has been with the Malaysia’s Sepang Today since 2007, bringing extensive hands-on experience in designing recirculating aquaculture systems (RAS) and biofloc systems. His expertise spans project implementation and farming operations for hatcheries and grow-out facilities. Jia-Zin has actively worked with various species, including coral trout, hybrid grouper, giant grouper, seabass, and vannamei shrimp.

Currently based in Sepang, with a hatchery operation in Perak, Jia-Zin believes that integrating AI into aquafarming systems holds significant potential for the long-term aquaculture industry. Specifically, in hybrid grouper RAS farming, AI can play a crucial role in optimizing system performance.

Speaker Dialogue: Fish Farmers X Technology
Presentation    Holistic Development of Indoor RAS Farming from Farmer to Farmer


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.
