Effects of Six Stunning Methods on Nile Tilapia Welfare and Fillet Quality

A 2026 study by Arnan Hirunratanakorn compares six stunning methods for Nile tilapia slaughter. The dataset, published on figshare, includes welfare indicators and meat quality parameters for 54 fish. It analyzes behavioral responses, morphological damage, and postmortem biochemical changes.

Use Cases

• Compare the efficacy of stunning methods based on behavioral response scores and morphological damage indices.
• Model the relationship between stress biomarkers like muscle lactate and fillet quality outcomes such as texture and color.
• Evaluate the impact of slaughter technique on postmortem physiological parameters like rigor mortis index and ATP levels.

Strengths

• Explicitly compares six distinct stunning methods (priest stunning, bolt pistol, ikijime, live freezing, anesthetic overdose, asphyxiation).
• Includes quantitative welfare metrics like behavioral response (BR) scores and morphological damage (MD) indices.
• Assesses multiple fillet quality parameters including texture, color, proximate composition, and water drip loss.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 212.0 KB DOCX file, suggesting a limited scope, likely a supplementary document rather than raw data.
