Length–weight relationships for 19 labrid species from the southern Atlantic Ocean

Summary Length–weight relationships were estimated for 19 labrid species occurring in the southern Atlantic Ocean. Data were collected from 175 specimens between July 2013 and February 2014. Most specimens were obtained from ichthyological collections, but some were spear‐fished. Labridae is one of the most diverse and representative fish families in reef systems. Relationships are novel for 13 of the species, with the remainder representing an increase in their geographic extension or size range.
