ABSTRACT
Age determination of fish in a multi-species fishery from the otolith or other hard parts of fish is time consuming and expensive process. There are some relationships between otolith and fish age. In this study, Otolith length (Ol), Otolith width (Owt), Otolith weight (Ow), Fish length (Lf) and Fish weight (Wf) were used to estimate the age of Common pandora, Pagellus erythrinus (L., 1758), using the general linear regression model; Y= Xβ+ε. Among the model with one variable, the model with Otolith length (Ol) variable was the best one, t = -2.101+0.691(Ol) (R2 = 0.862). Adding the other variables to the model did not have any significant effect on R2 values.
