Abstract
The growth and longevity of Amblypharyngodon mola was studied in the Payra River, southern Bangladesh, using length-frequency distributions during February 2016-January 2017. Both males and females first recruited in June, with modal size around 25â¯mm standard length. Growth for both sexes was described by the von Bertalanffy growth equation as: Ltâ¯=â¯50.10[1â¯ââ¯exp {â0.145(tâ¯+â¯2.926)}] for males and Ltâ¯=â¯51.64[1â¯ââ¯exp {â0.135(tâ¯+â¯3.326)}] for females. Both sexes showed similar growth patterns as no significant difference was observed between the sexes (F-test, Fâ¯=â¯1.89; pâ¯=â¯.167). The longevity of this species was estimated to be 1â¯+â¯year (13â¯months for males and 15â¯months for females). Standard length vs. body weight relationship indicated an isometric growth in both sexes. However, ANCOVA revealed significant differences in intercept (pâ¯<â¯.05) between sexes, though not with slopes (pâ¯=â¯.420).
