Download scientific diagram | Relationship between fork length (FL) at capture and (A) otolith size (OS) measured across transverse sections and (B) scale size (SS) measured from the focus to the anterior edge. Regression lines depict linear (dashed lines) and logarithmic fits (solid lines). For A, linear: OS = 1.89 + 0.09 · FL, r 2 = 0.94; log: OS = 3.29 · log e FL – 6.32, r 2 = 0.95. For B, linear: SS = –0.12 + 0.07 · FL, r 2 = 0.88; log: SS = 2.38 · log e FL – 6.07, r 2 = 0.89. from publication: Longitudinal Length Back-Calculations from Otoliths and Scales Differ Systematically in Haddock | Parallel macrostructure analysis of otoliths versus scales was conducted on Georges Bank Haddock Melanogrammus aeglefinus sampled in spring 2011 to test whether annuli widths of both structures yield comparable estimates of back-calculated length at age.
