    Author(s): Neeti Mishra* and Amitabh Chandra Dwivedi

    <p>Studies were undertaken during the period February 2019 to 2020 January from the lower  stretch of the Tons River  at Prayagraj, Uttar Pradesh, India.  During the present work, 683 fish specimens of Nile Tilapia, <em>Oreochromis niloticus </em>(336 males and 347 females) were studied for estimation of  age composition, age and growth increment. An over-all representation of age, growth increment and age composition of <em>O. niloticus </em>has been obtained by the  study of its key scales. The age composition of <em>O. niloticus </em>varied from 0+ to 7+ age groups. The maximum growth  increment was recorded  during first year of life cycle and showing a gradual decrease in growth as the  fish got older. The minimum growth increment  was recorded during  the seven year of the life cycle. &nb.. View More»
