Summary

Length–weight relationship (LWR) and length–length relationship (LLR) were estimated for six species of ponyfishes captured in the Persian Gulf, Iran. The LWRs indicated isometric growth in ornate ponyfish (Equulites lineolatus), common ponyfish (Leiognathus equulus) and deep pugnose ponyfish (Secutor ruconius) species, positive allometric growth in striped ponyfish (Aurigequula fasciata) and negative allometric growth in decorated ponyfish (Nuchequula gerreoides) and orangefin ponyfish (Photopectoralis bindus). LWR and LLR parameters for one of the species (E. lineolatus) are given for the first time. The relationships between TL, FL and SL were all linear and highly correlated (for all cases: r2 > 0.97)
