Hatay Açıklarında (Kuzeydoğu Akdeniz) yakalanan yeşilgöz balığının (Chlorophthalmus agassizi)'nin boy-ağırlık ilişkisi

Bu çalışma Kuzeydoğu Akdeniz'de yakalanan ve ekonomik öneme sahip olan yeşilgöz veya patlak göz balığı olarak da bilinen Chlorophthalmus agassizi türünün total boy-ağırlık ilişkilerinin saptanması amacıyla yapılmıştır. C. agassizi türüne ait tüm bireyler için 454 adet yeşilgöz balığı(165 dişi+289 erkek) ticari trol teknesi ile yapılan avcılıkta yaklaşık 150-300 m derinliklerde elde edilmiştir. Yakalanan balıkların minimum ve maksimum total boy ve ağırlıkları sırasıyla dişilerde 7.0-18.6 cm, 2.3-51.6 g ve erkeklerde 7.0-17.5 cm, 1.8-42.5 g olarak hesaplanmıştır. Türe ait total boy-ağırlık ilişkileri tüm bireylerde W=0.0038*L3.2432 (r2= 0.969, SEb =0.089) dişilerde W=0.0035*L3.2825 (r2=0.982, SEb =0.071) erkeklerde W=0.0049*L3.1299 (r2=0. 944, SEb =0.098) olarak bulunmuştur. Bu türün total boyağırlık ilişkisi erkek, dişi ve tüm bireylerde pozitif allometrik büyüme (b>3) göstermiştir

Length-weight relationship of greeneye fish (Chlorophthalmus agassizi) obtained from coast off Hatay (Northeast Mediterranean)

This study was carried out to determine the length-weight relationship of green eye fish (Chlorophthalmus agassizi) that have economic importance and obtained from Northeast Mediterranean. For this purpose, total 454 individuals (165 females and 289 males) of C. agassizi were captured with a commercial trawler form 150-200 m in depth. Minimum-maximum length and weight of captured fishes were determined as 7.8-18.6 cm and 2.3-51.6 g for males and 7.0-17.5 cm and 1.8-42.5 g for females respectively. Length-weight relationships were found as W=0.0038*L3.2432 (r2= 0.969, SEb =0.089) for all individuals, W=0.0035*L3.2825 (r2=0.982, SEb =0.071) for females and W=0.0049*L3.1299 (r2=0. 944, SEb =0.098) for males. Length-weight relationship of this species, all individuals, females and males of this fish species showed a positive allometric growth (b>3)
