Abstract


This research carried out to study the length-weight relationship (LWR) and length-length relationship (LLR) and condition factor (CF) of Sardina pilchardus in Edremit Bay. A total of 178 specimens were examined. Total length (TL) of the specimens ranged from 11.0 to 16.2 cm, while the standard length (SL) varied from 9.5 to 15.3 cm. Total weight (TW) ranged from 8.5 to 38.2 g. The calculated b value of the LWR indicated isometric growth for overall population. In the LLR analysis, females and the combined sex showed negative allometric growth, whereas males exhibited isometric growth. The mean CF was calculated as 0.80 ± 0.12 for combined sex, there were no significant difference between CF value of males and females. This study offers crucial insights into the growth patterns and health of S. pilchardus in Edremit Bay, contributing valuable data for stock assessment and fisheries management. The findings indicate that the population primarily exhibits isometric growth, while the condition factor suggests that Edremit Bay provides a suitable feeding environment for this species.
