Abstract
A total of 399 parrot fishes (Sparisoma cretense) were collected by trammel bottom nets between April 1985 and October 1986 off Kastellorizo Island (Dodecanese, Greece). The fishes were measured, sexed and aged, to determine some population parameters, such as growth, mortality and exploitation rate. One check mark per year occurring during spring was found on the scales. The relationship between scale radius and fish total length was plotted and the linear description was chosen for the back-calculation of length. No significant difference in length was found between sexes. Most growth takes place in the first three years of life, after which it proceeds slowly. Weight is proportional to the cubic power of length. Females mature in the first year, males in the third; the breeding season covers the summer months (July to September). The male to female ratio was almost 1:1.
