Map movement pathways and apply controls to people, animals, water, equipment, and feed.

Think in pathways

Pathogens can move with live animals, water, equipment, vehicles, footwear, wildlife, feed, and animal tissue. A biosecurity plan turns those pathways into controlled boundaries instead of relying on one disinfectant step.

Separate clean and exposed movement

Define entry points, restricted production areas, pond-specific tools where required, and a direction of travel that avoids carrying material from higher-risk to lower-risk areas. Make cleaning and disinfection stations easy to use and keep the records required by the farm plan.

Control what enters

Use approved suppliers and the farm's health and testing requirements for post-larvae and broodstock. Protect feed from pests, moisture, and contamination. Apply the approved treatment and verification process to incoming water; a treatment step is useful only when its operating conditions are checked.

Respond without spreading the problem

Unexpected mortality or clinical signs should trigger the site's notification and containment procedure. Restrict unnecessary movement, preserve records, and contact the responsible aquatic-animal-health professional or authority. White spots alone do not confirm white spot syndrome virus, and infected shrimp may show few or no white spots, so laboratory diagnosis matters.

Shift question

Before moving between areas, ask: What could I carry, where could it go, and what control does the farm plan require?
