Bu araştırmada İskenderun koyunda ekonomik yönden önemli olan üç ticari balık türünün toplam boy ve ağırlık ilişkileri (LWRs) ile Fulton’un kondisyon faktörünün (K) belirlenmesi amaçlanmıştır. Bu amaçla, kırlangıç balığı (Chelidonichthys lucerne, Linnaeus, 1758), dil balığı (Pegusa lascaris, Risso, 1810) ve çipura (Sparus aurata, Linnaeus, 1758) İskenderun koyundan 2016 yılında Eylül aylarında profesyonel bir balıkçı tarafından monofilament galsama ağ (göz açıklığı: 28) ile 10-20 metrede dipten toplanmıştır. Toplamda 82 balık örneğinin toplam boy ve ağırlıkları 0.01 cm ve 0.01 g hassasiyetle ölçülmüştür. Yakalanan balıkların minimum-maksimum uzunluğu ve ağırlığı C. lucerne için 14.0-24.5cm ve 31.2-126.6g, P. lascaris için 18.5-25.55cm ve 37.7-125.5g, S. aurata için 14.5-26.6cm ve 55.8-180.0g olarak belirlenmiştir. Üç balık türünün toplam boy-ağırlık ilişkisi C. lucerne için W = 0.0837 * TL2.28, P. lascaris için W = 0.0018 * TL3.45 ve S. aurata için W = 0.0667 * TL3.30 olarak bulunmuştur. Fulton’un kondisyon faktörü C. lucerne için 1.05 ± 0.04, P. lascaris için 0.72 ± 0.01 ve S. aurata için 2.00 ± 0.10 olarak tespit edilmistir. Bu çalışmanın sonuçları, bu alanda ekonomik açıdan önemli balıkların LWR parametrelerine ve K indislerine katkı sağlamakla birlikte, mevcut çalışma farklı zaman ve mekanlardaki benzer balık stoklarını karşılaştırmak için yararlı olacaktır.

Length-Weight Relationships with Condition Indices of Three Commercial Fish Species Caught by Monofilament Gillnets in the İskenderun Bay, Turkey

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.
