Indicator 2.4.2

This Indicator requires the UoC to prevent the escape of cultured animals. It focuses on three key aspects:
- Installation of containment structure; these structures must be appropriate for:
  - The species; consider size and behaviour
  - Different life stages; consider that smaller animals require different mesh sizes compared to bigger animals
  - Environmental conditions; consider currents, tides, floodings, floating debris, natural predators that can damage the containment structure.
Inspection of containment structures to check for structure integrity, including:
- Signs of damage or weaknesses; consider especially moving elements of the construction for ‘wear and tear’ signs
- Environmental conditions that impact the structure (e.g. erosion)
- Species-specific behaviours (e.g. net-biting, burrowing)
- Maintenance of containment structure:
  - Regular maintenance needs to be conducted so that containment structures are kept in, or restored to, a good state, or to prepare for known severe weather events (e.g. forecasted storms, flooding, etc.).

Escape prevention measures are installed according to construction specifications that incorporate environmental conditions and species-specific characteristics.
Documents demonstrating inspection and maintenance is occurring regularly and when needed (e.g. after a storm).

Escape prevention measures have been installed according to construction specifications and are appropriate to environmental conditions and species-specific characteristics.
Documents have been presented which demonstrate inspection and maintenance has occurred regularly and as required.
