Kuzeydoğu Akdeniz’de yakalanan kütük balığı (Hoplostethus mediterraneus)’nın boy-ağırlık ilişkisi

Bu çalışma Kuzeydoğu Akdeniz'de yakalanan ve kütük balığı olarak bilinen Hoplostethus mediterraneus türünün total boy-ağırlık ilişkilerinin saptanması amacıyla yapılmıştır. Kütük balığına ait toplam 380 örnek (143 dişi-237 erkek) ticari trol teknesi ile uluslararası sularda yapılan avcılıkta yaklaşık 200-380 m derinliklerde hedef dışı tür olarak elde edilmiştir. Yakalanan balıkların total boy ve ağırlıkları sırasıyla dişilerde 6,4-15,2 cm, 3,4-43,8 g ve erkeklerde 6,5-12,3 cm, 3,4-23,7 g olarak bulunmuştur. Kütük balığına ait total boy-ağırlık ilişkileri tüm bireylerde W=0,013*L2.9841, r2=0,9493 ve SEb=0,039, dişi bireylerde W=0,0128*L2.9929, r2=0,9388 ve ve SEb=0,068, erkek bireylerde W=0,0131*L2.9827, r2=0,9446 ve SEb=0,047 olarak bulunmuştur. H. mediterraneus türünün b değerine göre erkek, dişi ve tüm bireylerde izometrik büyüme gözlenmiştir (t-test: P > 0,05)

Length-weight relationship of Mediterranean slimehead (Hoplostethus mediterraneus) obtained from northeast Mediterranean

This study was carried out to determine the length-weight relationship of Mediterranean slimehead (Hoplostethus mediterraneus) obtained from northeast Mediterranean. For this purpose, a total of 380 individuals (143 females and 237 males) of H. mediterraneus were captured with a commercial trawler from 200-380 m in depth of international water region. Minimum-maximum length and weight of captured fishes were determined as 6.4-15.2 cm and 3.4-43.8 g for females and 6.5-12.3 cm and 3.4-23.7 g for males respectively. Length-weight relationships of H. mediterraneus were found as W=0.013*L2.9841, r2=0.9493, SEb=0.039 for all individuals, W=0.0128*L2.9929, r2=0.9388, SEb=0.068 for females and W=0.0131*L2.9827, r2=0.9446, SEb=0.047 for males. According to b values, all individuals, females and males showed an isometric growth (t-test: P > 0.05)
