Some biological properties of carp (Cyprinus carpio L.,1758) introduced into damsa dam lake,Cappadocia Region,Turkey

Age composition,length.weight relationships,growth,and condition factors of the carp (cyprinus carpio l.,1758) were determined using specimens (39.38% female and 60.62% male) collected from damsa dam lake between may 2010 and april 2011. the age composition of the samples was from i to viii. the length.weight relationship was calculated as w = 0.0181 tl2.9689 for females and w = 0.0278 tl2.8507 for males. the total lengths were between 17.1 and 69.2 cm,and the total weights were found to be between 86 and 5473 g. the majority of the individuals (48.12%) were between 46.0 and 55.0 cm length groups. the von bertalanffy growth equation were found as l∞ = 86.80 cm,k = 0.189,t0 = -0.396 for females and l∞ = 85.34 cm,k = 0.175,t0 = -0.468 for males. the growth performance index was also estimated as φ′ = 7.260 for females and φ′ = 7.151 for males. the mean condition factor was found as 1.582 for females and 1.572 for males. the total mortality (z) was calculated as 0.25 y.l-1. copyright 2014 zoological society of pakistan.
