Fish welfare assessment and technology documentation for aquaculture systems
Fish welfare in aquaculture
Fish welfare is increasingly in the spotlight for regulators, retailers, and consumers alike. The extent to which the environment and technology support the wellbeing of farmed fish directly impacts fish health, production performance, product quality, and brand reputation.
Fish farmers are expected to ensure and document animal welfare both during treatments and routine production to meet societal and market expectations.
How our fish welfare services support you
DNV provides comprehensive, structured welfare assessments based on recognized standards such as the Laksvel standard. By systematically reviewing welfare conditions and identifying challenges throughout the production chain, we help farmers pinpoint welfare issues and implement effective solutions.
Our fish welfare services include:
- Monitoring of Welfare: We perform ongoing welfare assessments aligned with the Laksvel standard, evaluating key indicators, such as behaviour, appetite, mortality causes, individual health makers (skin condition, anomalies, gill health, etc.), and environmental factors. Continuous monitoring, paired with scientifically grounded recommendations, enables producers to proactively address welfare risks before problems escalate.
- Generation Review of Welfare: At both site and corporate levels, DNV evaluates welfare performance over entire production cycles. These comprehensive assessments document and benchmark welfare outcomes, helping to identify systematic issues and enabling targeted improvements.
- Gap Analysis: Our welfare gap analysis identifies areas where current practices fall short of industry benchmarks or established welfare standards, providing clear direction for enhancements.
- Testing new equipment: Regulations require that new equipment potentially affecting fish welfare undergo welfare impact testing. DNV’s accredited field trial department has extensive experience in testing and validating new technologies to ensure they meet welfare requirements.

Frequently Asked Questions (FAQ)
-
Good fish welfare supports healthier fish, lower mortality, improved production performance and responsible aquaculture practices while helping producers meet regulatory and market expectations.
-
Fish welfare assessments typically evaluate health, behaviour, injuries, mortality, environmental conditions and operational practices to identify welfare risks and opportunities for improvement.
-
Digital technologies such as sensors, cameras, AI-based monitoring and automated systems can provide continuous insights into fish behaviour, environmental conditions and welfare indicators, supporting earlier intervention and better management decisions.
-
Yes. Better welfare can reduce stress, improve growth, lower mortality and support more efficient farming operations.
-
Assessments can be performed throughout the production cycle, including before stocking, during routine operations, following major treatments, after environmental events and as part of continuous improvement programmes.
-
DNV provides independent fish welfare assessments and technology documentation services to help producers evaluate welfare practices, verify technologies and strengthen confidence across aquaculture operations.
-
Independent assessments help producers demonstrate alignment with regulatory requirements, certification schemes and industry best practices while identifying opportunities for continual improvement.
-
Continuous monitoring enables earlier detection of welfare issues, supports proactive management and helps maintain healthy fish throughout the production cycle.
