Age of Jack mackerel Trachrus murphyi (Carangidae) using daily growth rings in sagittae otoliths
Growth of Jack mackerel (Trachurus murphyi) was estimated using daily growth rings in fish collected in central-south Chile from 2004 to 2011. The von Bertalanffy growth curve at length for both sexes (n=210 individuals) is FL = 75*[1-e-0.16(t+0 ...
