Fish Health, Welfare & Biosecurity
Protecting Fish, Farmers and the Future of Aquaculture
As aquaculture grows, fish health becomes critical national infrastructure. TCoE supports disease prevention, diagnostics, surveillance, biosecurity, water-quality management and vaccine development.
Disease risk increases as production expands. Higher stocking densities, increased movement of fingerlings, poor water quality, weak biosecurity and limited diagnostic capacity can quickly affect farm survival, investor confidence and national production.
TCoE is developing fish health and biosecurity services for farmers, hatcheries, government institutions and commercial producers. Our approach is preventive, practical and linked to real production systems.
What we provide
Six health & biosecurity services
Fish health advisory
Farm-level support on mortality investigation, disease risk, biosecurity, stocking practices and welfare management.
Water-quality testing
Monitoring and interpreting key water-quality parameters affecting fish survival, growth and disease susceptibility.
Disease surveillance
Structured data and field support for tracking aquatic animal health risks, especially in zones such as Lake Kariba.
Biosecurity systems
Farm biosecurity plans, hatchery hygiene protocols, movement controls, quarantine procedures and staff training.
Sampling & lab coordination
Support for sampling, diagnostic pathways and collaboration with university and government laboratories.
Vaccine development support
Vaccine development work targeting locally relevant tilapia disease challenges, focused on practical regional solutions.
Why it matters
Fish health is not only a farm problem. It affects food supply, farmer livelihoods, investor confidence, trade, hatchery reliability and environmental stewardship. Strong health systems prevent losses before they become sector-wide crises.
Who this service supports
Commercial farms, hatcheries, smallholder clusters, government agencies, laboratories, universities, development partners and investors operating in aquaculture production zones.
