Özet
Biology of piper Trigla lyra (Linneaus, 1758) distributing in Aegean Sea.In this study, age, growth and reproduction of Trigla lyra (L.) collected in Aegean Sea during 1991-1993 were studied.The fork length of individuals ranged from 62 to 542 mm.The slopes (b values) of the fork length-weight regressions indicated allometric growth for both sex groups (for females were b= 2.9396 and for males were b= 2.8877).The oldest individual was IX years.The von Bertalanffy growth parameters for sexes combined were L ∞ = 596.97mm, k= 0.16 y -1 , t 0 = -0.8632.According to the gonadosomatic index values, it was determined that reproduction period occurred during autumn and winter months.
