Totals of 284 Hemigrammocapoeta kemali specimens were caught during 1998 in the Isikli Lake, Turkey. Their ages, lengths and weights were determined to estimate length-weight relationships and age composition. Fecundity and oocyte diameter were also determined. The sex ratio was 1 : 1.29. Fork length and total weight of specimens ranged from 3.4 to 8.2 cm and from 0.5 to 6.9 g, respectively. Maximum age observed was 4 years. The length-weight relationship for all fish was best described by the equation W = 0.0121*L-3.06; the von Bertalanffy growth equations for length and weight were Lt = 8.73[1-e(-0.401(t + 0.947))]; Wt = 9.17[1-e(-0.401(t + 0.947))](3.06). Oocyte numbers varied from 220 to 1159 and oocyte diameters ranged between 450 and 900 mu m.
