Individual growth in Jack mackerel (Trachurus murphyi) of the Southeastern Pacific Ocean using sagitta otolith weight, daily rings, and annual rings

ABSTRACT We estimated the growth of Jack mackerel (Trachurus murphyi) using increments of daily growth, otolith weight and annual ring reading in sagittal otoliths. The daily micro-increments were used to fit ring density to the otolith radius (n = 4481) and then to estimate the age of the individua...
