| Daily growth of Atlantic juvenile hake from Northwest Iberia has been estimated employing a new approach combining analyses of transversal and sagittal sections of the otoliths along the ventral radius. Age of juvenile hake ranging from 3 to 25 cm collected during a spring 2002 survey was estimated. Somatic growth followed a power fit: Fish size (TL) = 3.3254*age(0.7336) (r(2) =0.87, p < 0.001, n = 76). yielding an average individual growth rate of 0.66 mm/day (0.06). The growth model indicates that after a year's life a juvenile can reach 25 cm. Otolith ventral radius ranged from 401 to 1842 mu m and daily increments were between 104 and 387. Fish growth and otolith growth were closely related (r(2) = 0.92 p < 0.001, n = 76). These first results of... |
