Orginal research papers
<p> Estimates of age, growth parameters, length-weight relationship and length and age at first maturity of the <i>otolithes ruber</i> are required for fishery management. We used counting annuli on the section of sagittal otoliths to age <i>O.ruber </i>from the Northwest Persian Gulf in south of Iran. Estimated ages ranged from 0 to 6 years, and maximum frequency of fishes was observed in age-group 1. The values of growth parameters L<sub>∞</sub>, k and t<sub>o</sub> were calculated by von Bertalanffy model and the results were 67.57 (cm), 0.27 (year<sup>-1</sup>) and -0.43 respectively. Parameters b and an in length-weight relationship were calculated 3.19 and 0.005 respectively. Length and age at first maturity were estimated 28 cm and 1.55 year. </p>
