Aquaculture Biosecurity Best Practices
Biosecurity is the systemic prevention of pathogen introduction, spread and impact in an aquaculture facility. A documented programme is the single highest-ROI compliance investment — 3–7% of CAPEX prevents losses that routinely reach 100% of a stocked cohort.

Biosecurity is a compliance discipline and an operational survival strategy. It is also the CAPEX line item most frequently under-funded — a documented biosecurity envelope typically costs 3–7% of CAPEX and prevents losses that routinely reach 100% of a stocked cohort.
The five biosecurity control layers
Zoning; incoming-water treatment; animal-input QA (SPF, PCR, quarantine); staff/vehicle/equipment decontamination; outbreak response plan with pre-authorised destruction and disinfection protocols.
Species-specific pathogen risk map
Shrimp: WSSV, EMS/AHPND, IHHNV, EHP. Salmon: ISA, PD, SRS, sea lice. Tilapia: TiLV, streptococcus. Marine fin-fish: VNN, AGD. Design the biosecurity envelope around your species and geography's specific threat profile.
Why insurance loves documented biosecurity
Every aquaculture insurance policy prices biosecurity design and documentation. Well-documented programmes reduce premium 15–30% and expand available cover.
The 90-day outbreak response drill
Every facility should run a full outbreak response drill within 90 days of first stocking, and repeat annually. The drill is the only reliable test that the plan works before it is needed.
Common mistakes
- No zoning plan — broodstock, larvae, live feed and grow-out share staff or equipment.
- Incoming-water disinfection sized for average pathogen load, not worst case.
- Missing outbreak response plan and rehearsal.
- No quarantine for incoming animals or live feed.
- Vaccination treated as a substitute for biosecurity rather than a complement.
Buyer compliance checklist
- Zoning plan documented and enforced.
- Incoming-water disinfection sized for worst-case pathogen load.
- PCR screening for species-specific pathogens on every incoming batch.
- Quarantine facility with independent water and air.
- Written outbreak response plan, rehearsed annually.
- Vaccination programme where applicable.
- Staff PPE and decontamination protocols posted and audited.
- Third-party biosecurity audit annually.
