Do I need a named veterinarian?

In most jurisdictions above a threshold biomass, yes — under written contract with defined scope.

Which stunning methods are accepted?

Percussive, electrical or chemical stunning, depending on species and market. EU and UK reject non-stunned slaughter for fin-fish. Check destination-market requirements.

How long is the withdrawal period for common medications?

Depends on molecule, dose and species — always follow the label plus a safety margin. Track in a residue-management log.

Is animal welfare regulated for shrimp?

Less than for fin-fish, but retailer-driven welfare requirements are extending to shrimp. Expect this to accelerate.

What is the mortality reporting threshold?

Varies by jurisdiction — many require notification above 1–5% daily mortality. Even below threshold, root-cause investigation is a defensive standard.

Aquaculture Animal Health & Welfare

Animal-health compliance is where regulatory enforcement has tightened fastest, driven by OIE guidance, EU welfare rules and retailer-led certification requirements. Every commercial operation needs a documented programme covering veterinary supervision, vaccination, medication, welfare and slaughter.

• Every aquaculture operation

Why it matters

Animal-health compliance is where regulatory enforcement has tightened fastest. EU, UK and increasingly retailer-driven markets require documented welfare programmes; commercial mortality events invite regulator scrutiny.

The OIE Aquatic Animal Health Code

The international reference for aquatic animal disease prevention, control and reporting. National regulations translate OIE guidance into enforceable rules; producers exporting internationally must be aligned with both.

Fish welfare — beyond biosecurity

Space allowance, water quality thresholds, handling protocols, humane slaughter. EU and UK now enforce welfare requirements; several retailers require certification against RSPCA Assured or GLOBALG.A.P. animal welfare add-ons.

Medication and residue rules

Every medication used must be logged with withdrawal-period compliance verified before harvest. Residue detection is the leading cause of export rejection after documentation error.

Common mistakes

Vaccination records missing or incomplete.
Stunning / slaughter methods not aligned with market expectation.
