Aligned with agriculture and food science priorities, YHL addresses food security while protecting marine ecosystems and reducing climate impact. By shifting demand away from wild-caught shrimp, adopting Malaysia’s first large-scale IMTA system to recycle aquaculture water, and building a fully local, integrated supply chain, YHL lowers environmental pressure and carbon footprint. Our locally bred broodstock reduces reliance on imports, while our projects create jobs and skills for B40 communities through sustainable aquaculture.
Our shrimp farms operate within an IMTA framework.
Waste nutrients generated during shrimp cultivation are channelled through multiple biological layers:
This system reduces nutrient discharge, lowers environmental stress, and produces water that can be safely reused or released.
IMTA is not a pilot concept at YHL — it is our operating baseline.
YHL is integrating mangrove restorative aquaculture into its IMTA framework.
Mangroves:
Sequester carbon from nutrient-rich wastewater
Act as natural biofilters
Create habitat complexity and biodiversity
Stabilise water chemistry before final discharge or reuse
Conventional aquaculture optimises for short-term yield.
YHL optimises for:
Our farming model is designed to be copied responsibly — not just expanded aggressively.
YHL has dedicated 9 acres of land to develop six interconnected ponds that work synergistically to achieve the IMTA effect.
