Animal welfare in aquatic production has been gaining increasing attention in discussions about the future of aquaculture. In this context, understanding how certification programs incorporate welfare criteria into their standards is essential for producers, companies, retailers, researchers, and other stakeholders across the production chain.

This is precisely the purpose of the Aquaculture Certification Schemes Benchmark, developed by the Aquatic Life Institute (ALI).

In its fifth edition, published in September 2026, the Benchmark evaluated 12 certification programs and 2 rating agencies, representing the largest scope reached by the study to date.

For the second consecutive year, Certified Humane ranked first, achieving a score of 9.5/10.

What is the Aquaculture Certification Schemes Benchmark?

The Aquaculture Certification Schemes Benchmark is a global, evidence-based tool that evaluates how aquaculture certification programs and product rating systems incorporate animal welfare requirements into their standards.

In other words, the study seeks to answer an important question:

To what extent do aquaculture certification programs establish clear criteria to protect the welfare of farmed aquatic animals?

The Benchmark compares the requirements established in different programs’ standards and assigns scores based on the presence and strength of criteria related to animal welfare.

According to ALI, it is the only global evidence-based tool specifically dedicated to assessing the strength and clarity of animal welfare language within aquaculture certification and rating frameworks.

The results can be used as a reference by certification programs, seafood companies, retailers, policymakers, researchers, investors, and animal protection organizations.

What does the Benchmark evaluate?

The assessment considers different aspects related to the living conditions and management of aquatic animals.

Among the main criteria evaluated are:

Water quality

Water quality is fundamental to the welfare of aquatic animals. Therefore, the Benchmark evaluates whether standards establish requirements related to monitoring and maintaining adequate water quality conditions.

Stocking density

The study also analyzes requirements related to the number of animals kept within a given space.

Stocking density can directly influence animals’ living conditions and is associated with factors such as behavior, water quality, and opportunities for interaction with the environment.

Environmental enrichment

Another aspect evaluated is whether standards include requirements that encourage environments more suited to animals’ behavioral needs.

This is one of the areas where the sector still has opportunities for improvement. The 2026 assessment indicates that aspects related to behavior and the ability to express natural behaviors remain less developed compared to operational welfare criteria.

Feed

The Benchmark also evaluates how standards address feed composition and feeding management practices.

Transport and handling

Transport and handling are important stages for animal welfare and are also included in the assessment.

In the 2026 edition, the transport criterion was expanded to also include routine handling practices.

Stunning and slaughter

Requirements related to stunning and slaughter are also considered in the evaluation, assessing whether standards establish procedures aimed at reducing animal suffering.

In addition to these criteria, what else is considered?

The Benchmark also assigns scores to certain prohibitions considered relevant for animal welfare.

These include:

• farming octopuses and other cephalopods;
• eyestalk ablation in shrimp;
• the use of insects as feed for aquatic animals;
• the use of genetically modified organisms to accelerate growth;
• inappropriate use of antimicrobials.

In the 2026 edition, inappropriate antimicrobial use became one of the core prohibitions assessed.

The report also highlights that six evaluated programs now prohibit the farming of octopuses or other cephalopods: Certified Humane, RSPCA, ASC, Soil Association Organic, Friend of the Sea, and Best Aquaculture Practices (BAP).

What does the Benchmark NOT evaluate?

This point is important.

The Aquaculture Certification Schemes Benchmark is an assessment exclusively focused on animal welfare.

Therefore, the score does not represent an overall evaluation of certification programs.

The study does not assess:

• environmental sustainability;
• food safety;
• social responsibility;
• governance performance;
• implementation of standards on farms;
• compliance of certified operations with the standards.

In other words, a high Benchmark score means that a program has clearer and stronger requirements related to animal welfare, but it does not necessarily indicate the best performance across all other dimensions of aquaculture production.

Certified Humane ranks first again

In the 2026 edition, Certified Humane achieved 9.5 points, maintaining the leading position for the second consecutive year.

The result also represents an improvement compared to the previous edition. In 2025, Certified Humane received 8.75 points and also ranked first.

The three highest scores in 2026 were:

1st Certified Humane: 9.5
2nd RSPCA: 8.45
3rd ASC: 7.95

The improvement in Certified Humane’s score followed the incorporation of new animal welfare provisions into its standards, including updates made based on recommendations presented by ALI in the 2025 Benchmark.

Why is this assessment important for aquaculture?

Aquaculture plays an increasingly important role in global food production, with billions of aquatic animals raised in farming systems worldwide.

At the same time, scientific knowledge about the welfare of these animals continues to advance.

In this context, establishing clear welfare criteria within certification standards can help translate scientific knowledge into practical requirements for production systems.

The ALI Benchmark provides an overview of which aspects are already more established within certification standards and which areas still require further development.

According to the 2026 assessment, requirements related to feed, water quality, stocking density, transport and handling, and stunning and slaughter are increasingly present in the evaluated standards. On the other hand, aspects related to behavioral welfare, environmental complexity, and opportunities for expressing natural behaviors remain areas requiring further development.

Recognition for advancing animal welfare

Certified Humane’s first-place ranking in the 2026 Benchmark represents recognition of the presence of animal welfare requirements within its aquaculture certification standards.

The result highlights the importance of establishing objective, evidence-based, and continuously improved criteria to guide the responsible farming of aquatic animals.

For Certified Humane, this recognition reflects a commitment at the core of its work: supporting farming conditions that consider animals’ needs and contributing to concrete advances in animal welfare.
