Length–weight relationships of three fish species of coral reef fishes from the northeastern of the Persian Gulf

The investigation presents length–weight relationships for three coral reef fish species: Cephalopholis formosa (Shaw, 1812); Chaetodon nigropunctatus Sauvage, 1880; and Pomacanthus maculosus (Forsskål, 1775). The specimens were captured between April to August 2015 by spear‐gun and wire trap (mesh size: 35 mm) in coral reefs of the northeastern areas of the Persian Gulf.
