Summary of Barrier Management in the Aquaculture Industry

Core Content

Barrier management is a key risk management tool in the aquaculture industry aimed at reducing the risk of fish escape and health issues. It involves identifying, analyzing, and managing barriers that prevent or mitigate unwanted events. This approach is aligned with Norwegian legislation and is designed to support sustainable and profitable operations by ensuring that facilities are safe, effective, and compliant with regulatory standards.

Main Objectives

• To reduce the risk of fish escape and health problems
• To achieve operational targets by managing unwanted events
• To simplify interaction between authorities and the industry
• To enable a more efficient and risk-based auditing regime

Key Views

Barrier management is a systematic and continuous process that includes three main stages:

1. Define and establish barriers – Identifying and setting up the necessary barriers to prevent unwanted events.
2. Monitor and assess barriers' performance – Ensuring that barriers are functioning as intended and identifying any weaknesses.
3. Ensure barriers' performance and mitigate weaknesses – Implementing corrective actions to maintain barrier effectiveness and reduce risk exposure.

Barrier management is compatible with existing regulations and is an integral part of corporate governance and internal control. It supports the implementation of risk assessments, emergency preparedness plans, and compliance with legal requirements, particularly those related to fish escape and health.

Key Information

Types of Barriers

Barriers can be categorized into three types:

• Technical barriers: Physical equipment and systems that prevent unwanted events.
• Operational barriers: Actions and activities that personnel must perform to maintain barrier functionality.
• Organizational barriers: Defined roles and responsibilities of personnel with the necessary expertise and competence.

Performance Requirements

Performance requirements for barriers are typically defined by the company or by the authorities. For example, technical barriers must meet standards in terms of functionality, availability, and reliability. Organizational barriers require specific competence and training, while operational barriers focus on task performance and response times.

Risk Assessment and Monitoring

Risk assessment is the foundation for identifying and establishing barriers. Monitoring is essential to assess how well barriers are functioning and to detect any weaknesses. This includes:

• Daily inspections
• Certification processes (e.g., NYTEK, ASC, GGAP)
• Internal audits
• Emergency preparedness exercises
• Maintenance records and incident reports

Tools and Visualization

The bowtie diagram is a key visualization tool used in barrier management. It illustrates the relationship between threats, unwanted events, consequences, and the barriers that prevent or mitigate them. The diagram helps in assessing the current status of barriers and their effectiveness in risk reduction.

Importance of Information Flow and Quality

• A structured information flow is essential for effective barrier management.
• Information must be clear, unambiguous, and objective to support accurate risk assessments.
• Digital systems can be used to gather and document barrier-related information efficiently.

Conclusion

Barrier management is a proactive and systematic approach to risk control in aquaculture. It helps ensure that both the design and operation of facilities are aligned with regulatory requirements and that risks are minimized through continuous monitoring, assessment, and mitigation. The process requires collaboration between the industry and authorities, as well as the use of tools like the bowtie diagram to visualize and manage risk effectively.
