Length-weight relationship (LWR) and condition factor (K) of 1440 fish populations covering 6 families and 6 species inhabiting southern Black Sea, were studied. The fishes Belone belone (garfish), Pomatomus saltatrix (bluefish), Spicara flexuosa (picarel), Scorpaena porcus (scorpion fish), Uranoscopus scaber (stargazer) and Trachurus trachurus (horse mackerel) were sampled from Ordu province (Turkey) from November 2017 to september 2018. “b” value indicated isometric growth for P. saltarix (3.0913) and U. scaber (3.0231), while B. belone exhibited negative allometric growth (2.7052) and, S. flexuosa (3.0915), S. porcus (3.0785) and T. trachurus (3.5118) exhibited positive allometric growth. The condition factor varied between 0.11 (B. belone) and 2.02 (S. flexuosa).

Araştırmada güneydoğu Karadeniz’de yaşayan 6 familyaya ait 6 balık türünü içeren 1440 balığın boy-ağırlık ilişkisi ve kondisyon faktörü çalışılmıştır. Kasım 2017-Eylül 2018’de Ordu bölgesinden (Türkiye) elde edilen balıklar: Belone belone (zargana), Pomatomus saltatrix (lüfer), Spicara flexuosa (izmarit), Scorpaena porcus (iskorpit), Uranoscopus scaber (tiryaki) ve Trachurus trachurus (istavrit)’dur. “b” değeri P. saltarix (3.0913) ve U. scaber (3.0231) için izometrik büyümeyi, B. belone için negatif allometrik büyümeyi (2.7052) ve S. flexuosa (3.0915), S. porcus (3.0785) ve T. trachurus (3.5118) için pozitif allometrik büyümeyi işaret etmektedir. Kondisyon faktörü 0.11 ( B. belone) ve 2.02 (S. flexuosa) arasında değişmektedir.
