Temporal changes of the morphological indices (Relative Gut Length (RGL), Fullness Index (FI), Hepatosomatic Index
(HSI), Visceral Index (VSI), Gonadosomatic Index (GSI) and Fulton condition)) in 122 (♀: 94, ♂: 19, immature: 9)
common sole were evaluated. Total length-weight relationships were calculated as W = 0.085TL3.01 and W = 0.0547TL2.40
in females and males, respectively, whereby isometric growth was observed in females and negative allometric growth was
observed in males. While there was no statistically significant difference was observed between the FI, HSI, Viscerosomatic
Index (VSI), RGL and GSI values of both sexes, however, there was a statistically significant difference in terms of
Fulton K values (P < 0.05). In addition, there are statistical differences between the sexes total lengths and the values of
RGL, FI, HSI, VSI, and Fulton-K (P < 0.05), as it is discernible in their HSI and VSI index values according to the month
the specimens were obtained (P < 0.05). According to the results of the analysis, it has been determined that the female
common sole along the Aegean coast adjust their energy temporally and store the energy they obtain from vegetative and
carnivorous feeding. Contrary to the situation seen in females, the male individuals invest in energy through omnivorous
feeding, according to the diet in the active process. Based on the results, it can be stated that the VSI and HSI are both
important indicators of fish condition status. The results found here may be useful in both fishery research and fishery
management.
