Age and growth modelling for early stages of the jumbo squid Dosidicus gigas using multi-model inference

Age and growth were estimated for early growth stages of the jumbo squid Dosidicus gigas in the Gulf of California, based on daily growth increments in statoliths. Three individual growth functions that showed non-asymptotic patterns (two cases of the Schnute general model, and Tanaka mode!) were fitted to lengthat-age data. Using Akaike's Inforrnation Criterion and multi-model inference, we selected the best model to describe the growth pattern. We found that the Schnute general model was the best growth function describing mande length-at-age data for paralarvae and juveniles of D.gigas, showing a power pattern.Absolute daily growth rate ranged from 0.03 to 1.66 mm day, with lower values for paralarvae and higher values for juveniles.
