The effect of using incorrect equations for reconstructing fork length across the full-size range of LD1 cranial measurement on albacore bones. The Y axis shows the error that is introduced as a result (mm difference in estimated fork length). This shows that equations for quite different species could be used for albacore without significant error. Further support for this is a recent allometric study of 13 species of scombrids which provides supporting evidence of co-linearity between live length and bone dimensions (Elliott Smith et al. 2026: fig. 2).
