Resumen o descripción
"In age and growth studies the individual variability is recognized as a source of bias, if it is not taken into account in the analyses it can lead to overestimates or subestimates of the mean length at age of a cohort. In this study, a new approach for analyzing individual shell length-at-age variability was developed for Panopea globosa using a joint negative log-likelihood where both shell length frequency distributions (0.105–7.04 mm) and shell length–at-age (100–187 mm) data sets were combined. Six candidate growth models were analyzed that included assumptions about the variance for each age in the population, and the best growth model was selected using a multimodel inference approach. Growth modeling including phenotypic growth variability showed that estimates of to were better than those computed from conventional growth models. We found that the Johnson model was the best candidate growth model for fitting both data sets."
