Özet: In this study, it was aimed to determine the length and weight relationships (LWRs) and Fulton’s condition factors (K) for three commercial fish species in İskenderun bay. For this purpose, tub gurnard (Chelidonichthys lucerne, Linnaeus, 1758), sand soles (Pegusa lascaris, Risso, 1810), and gilthead seabream (Sparus aurata, Linnaeus, 1758) were collected by a single artisanal fisherman during September- December months in 2016 by means of monofilament gill nets mesh size:28 mm) used at deepths 10-20 m in İskenderun bay. Totally 82 fish samples captured and total lengths and weights of they were measured to the nearest 0.01 cm and to 0.01 g. Minimum-maximum length and weight of caught fishes were determined as 14.0-24.5cm and 31.2-126.6g for C. lucerne, 18.5-25.55cm and 37.7-125.5g for P. lascaris, 14.5-26.6cm and 55.8-180.0g for S. aurata. Total length-weight relationships of three fish species were found as W=0.0837*TL2.28 for C. lucerne, W=0.0018*TL3.45 for P. lascaris, and W=0.0667*TL3.30 for S. aurata. Fulton’s condition factors were detected as 1.05±0.04 for C. lucerne, 0.72±0.01 for P. lascaris, and 2.00±0.10 for for S. aurata. Result of this study provides a contribution to parameterers of LWRs and K indices of economically important fish in this area and the current study will be useful in order to compare the stocks of similar species in different temporarily and spatially.
