Özet
The length and weight distribution of flounder (Platichthys flesus luscus Pallas, 1811) were 14.2-34.1 cm and 28.879-611.0 g, respectively. The samples were distributed between the 0 and VII age groups. Von Bertalanffy growth parameters for flounder were Lt = 41.241[1-e-0.161(t+3.240)] for females, Lt= 33.567[1-e-0.181(t+3.525)] for males and Lt = 40.577[1-e-0.142(t+3.105)] for the sexes combined. Reproduction took place from December to March but peaked in December. Two recruitment periods were determined for flounder: the first was January to July, and the second August to November. The proportions of recruitment in the first and second periods were 68.13% and 31.87%, respectively.
Abstract
The length and weight distribution of flounder (Platichthys flesus luscus Pallas, 1811) were 14.2-34.1 cm and 28.879-611.0 g, respectively. The samples were distributed between the 0 and VII age groups. Von Bertalanffy growth parameters for flounder were Lt = 41.241[1-e-0.161(t+3.240)] for females, Lt= 33.567[1-e-0.181(t+3.525)] for males and Lt = 40.577[1-e-0.142(t+3.105)] for the sexes combined.
