Meilleures pratiques de biosécurité
La biosécurité est la prévention systémique de l'introduction, de la propagation et de l'impact des pathogènes. Un programme documenté est l'investissement conformité au meilleur ROI.

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.
Erreurs courantes
- 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.
