Abstract

Selected biometric characters, weight-length relationships and growth rates of Aqaba species Parupeneus cinnabarinus were studied. A total of 17 of the 20 morphometric measurements investigated grew isometrically with fish length. The eye diameter changed in a negative allometry while body depth and width showed a positive allometry. Counts of seven meristic characters were recorded. The weight of fish increased in positive allometry as the fish increased in size, with a growth factor (n) of 3.1748. The von Bertalanffy equation applied well for the growth calculations with growth factors of L∞ = 44.4 cm, K = 0.208 and tₒ= -0.998.
