Growth Biology of the Topmouth Gudgeon (Pseudorasbora parva) from Lake Mogan (Ankara, Turkey)

In this study, the growth biology of topmouth gudgeon, Pseudorasbora parva (Temminck & Schlegel, 1846), sampled from Lake Mogan, Ankara, Turkey were studied between July 2013 and June 2014. Length-weight relationship, von Bertalanffy growth equation, Fulton’s condition factor and rational growth increase were evaluated from obtained data. Length-weight relationship was estimated as W=0,0138xTB2,8414(r2 = 0,948). von Bertalanffy Growth Model was calculated as Lt= 106,8495[1-e-0,212451(t+2,59075)]. Fulton’s condition factor was found at the lowest level in fall and winter season, increasing the beginning of spring season due to the annual reproductive cycle
