Biofloc aquaponics presents a sustainable approach to soilless crop production, but its long-term reliability is often compromised by root-zone disorders such as root rot and wilt. This study evaluated four media-based biofloc aquaponic designs over two years (encompassing two full fish production cycles and four tomato growing seasons) to investigate system failures, including plant wilting, necrosis, and the underlying physical and microbial stressors. In the first year, plant wilt was primarily linked to poor drainage and sludge accumulation in coupled systems, resulting in root-zone hypoxia and a 21% reduction in yield compared to decoupled systems. In response, system modifications were implemented in the second year, including the implementation of radial flow settlers upstream of filters and timer-controlled pumps, which improved oxygenation and solids management. These interventions reversed previous trends: coupled systems had > 45% higher yields than decoupled systems. However, wilting still occurred in a subset of plants during the second year. Root-zone analysis showed that wilted plants exhibited 65% lower dissolved oxygen levels than non-wilted, and a tendency for higher relative abundance of potential pathogens and parasitic organisms (Pythium graminicola and Xiphinema rives). In contrast, healthy root zones were associated with greater abundance of plant growth-promoting bacteria (PGPB), particularly taxa with known biocontrol potential. These findings highlight the importance of maintaining oxygen-rich root environments and effective solids management to support long-term aquaponic productivity.

KUALA LUMPUR, April 30 (Bernama) — The Department of Fisheries Malaysia (DOF) is stepping up efforts to strengthen the aquaculture sector by adopting biofloc technology to boost food security and sustainable productivity. In a statement today, DOF said the environmentally friendly system uses a ‘recycling’ concept to convert aquaculture waste, including ammonia from fish excrement and excess feed, into microbial protein or flocs. “These flocs serve as a natural food source for species such as tilapia, white shrimp (vannamei) and catfish, reducing reliance on commercial feed by 20 to 30 per cent,” it said. As of 2025, production reached 1,500 […]

What does it take to turn a small fish-selling business into a modern aquaculture venture? In this episode of Scaled, we follow Shaukat Hussain, a Karachi-based entrepreneur who moved from traditional fish selling to biofloc fish farming, a system that allows high-yield fish production in controlled tanks. Starting with just a few small tanks, his operation has now grown to 18 large tanks, along with a company — As Samaak Biofloc Fish Farming — that provides training and services across Pakistan and the Middle East. This video explores how biofloc farming works, what it takes to scale it, and how one entrepreneur turned a simple idea into a growing business.
