Overview

Analysis identifies fin clips as less effective than muscle and liver for stable isotope studies in pelagic teleosts, suggesting the need for alternative biochemical methods.

Key Points

Fin clips showed limited effectiveness in capturing spatiotemporal variation in isotopes and lipid content, which are crucial for detailed dietary analysis.
Significant regional variability was found in fatty acid profiles, especially for polyunsaturated fatty acids EPA and DHA, valued for human nutrition.
Tissue analysis indicated muscle was the most effective at capturing biochemical trends, while liver tissue displayed greater variability in data collected.
The study suggests fin clips may still provide a minimally invasive option for certain fatty acid analyses, supporting conservation efforts for endangered species.
