Length- weight relationships were calculated for 22 fish species caught from Candarli Bay in the north Aegean Sea, Turkey. Between December 2006 and January 2008 beach seine net was use to capture Specimens and sampling was made in vegetated and sandy bottoms at the depths up to 1.5 m. A total of 2605 fish specimens were weighed and measured. The sample size ranged from 4 for Symphodus cinereus, Symphodus doderleini to 1558 for Atherina boyeri. The values of exponent b in the length-weight regressions (W=aL(b)) varied between 1.93 (Belone belone) and 3.475 (Symphodus ocellatus). Linear regressions of length-weight relationships were significant for all species. The length-weight relationships given here for Symphodus doderleini, Symphodus cinereus, Symphodus ocellatus and Pomatoschictus minutus were the first time for the north Aegean Sea.
