ResumoGrowth rates of three commercial species of Lutjanidae were estimated from sections of vertebrae cross‐checked with scales. The von Bertalanffy growth constants for Lutjanus malabaricus were K =0.168, L ∞ =70.7 cm standard length (S.L.). For Pristipomoides multidens these were K = 0.219, L ∞ = 59.1cm, and for Pristipomoides typus K =0.254, L ∞ = 51.5 cm. Length/weight was analysed in the form W= aL b where W was fresh weight (g) and L = S.L. (cm). The constants were: L. malabaricus, a = 0.041, b = 2.842; P. multidens, a =0.032, b = 2.897; P. typus, a = 0.038, b = 2.822. The growth rates were considered low in comparison with demersal fish counterparts from temperate seas.
