Weight-length regressions are presented for 33 fish species caught dur
ing 1992-1993 in the South Euboikos Gulf, Aegean Sea. Samples were col
lected with beach seine and gill and trammel nets. The values of the e
xponent b in the weight-length relationship W = aL(b) ranged from 2.32
0 to 3.521 and the median value was 2.987, whereas 50% of the values r
anged between 2.840 and 3.140. The application of these regressions sh
ould be limited to the observed length ranges.
