Investigation of Growth Features of Perch (Perca fluviatilis L. 1758)Population in Urkmez Dam Lake(Izmir-Turkey)

In this study, the growth properties of perch (Perca fluviatilis L. 1758) population living in Urkmez Lake were investigated. The ages of 876 fish specimen which was caught from june 1997 to May 1999 ranged from I-IV. The population was composed of 52.78 % females and 47.22 % males. The fork lengths and weights of caught samples on female and male varied from 15.97 to 32.01 cm, and 15.87 to 31.43 cm and 79.69 to 697.83 g and 80.87 to 674 g, respectively. Length-weight relationships were found as W= 0.0082*L3.2716 for males, W= 0.01*L3.2097 for females and W=0.0082*L3.2716 for combined sex. Growth parameters were estimated as; L∞= 49,621 k=0.205, to= -0835 for males, L∞= 49.983, k=0,212, to= -0.838 for females and L∞= 51.16, k=0,199, to= -0,865 for combined sex.
