The Patagonian rockfish Sebastes oculatus and the Brazilian sandperch Pinguipes brasilianus are two of the most abundant, conspicuous reef fishes in the northern Patagonian gulfs of Argentina. Here, we provide separate length-weight relationships for males, females and pooled individuals of these species for the North Patagonian region, based on samples collected between 2009 and 2014, throughout the year, between 42°S and 45°S. No length-weight relationships for P. brasilianus are available in the literature. Besides, although one relationship was published for S. oculatus from Chilean waters, the limited number of fish and their size range did not allow estimating the model parameters accurately
