Total length estimation of the Brazilian flathead Percophis brasiliensis, using morphometric relationships of skull, pectoral girdle bones, otoliths and specific body measures, in Argentine waters

Predictive regression equations were generated to estimate total length of the Brazilian flathead (Percophis brasiliensis) fish using skull and pectoral girdle bones as well as specific body and otolith lengths. All regressions were statistically significant. The features of bone and external body regressions evidently have the capability to increase the amount of dietary information obtainable from stomach content analy- ses of the Southwest Atlantic piscivores.Fil: Perez Comesaña, J.E..
