An estimation is given of growth parameters of grey triggerfish (Balistes capriscus ) occurring off the coast ofGhana. Growth was estimated by observing annuli in the dorsal spine. From the distribution of observed length at age, mean lengths-at-age of 14.4, 23.6, 29.2, and 33.0 were obtained for age groups I, II, III and IV, respectively. From these, estimates of L sub( alpha ) = 40.8 cm and K = 0.43/year were obtained.
