Çanakkale Boğazı'ında dağılım gösteren iskorpit balığı (Scorpaena porcus linneaus 1758)'nın bazı büyüme parametreleri

Çanakkale Boğazı’nda dağılım gösteren İskorpit balığı’nın (Scorpaena porcus Linneaus, 1758) yaş, boy ve ağırlık ilişkilerini saptamak amacıyla, Nisan 2000 – Mart 2001 tarihleri arasında toplam 168 adet balık incelenmiştir. Balık otolitlerinde yapılan yaş tayinine göre örneklerin I - X yaşları arasında olduğu ve bunların yaklaşık % 92,3’ünü I ve VI yaş balıkların oluşturduğu saptanmıştır. Ortalama balık boyu 21,22±0,89 cm (minimum: 10,5 cm; maksimum: 32,0 cm) ve ortalama balık ağırlığı 163,72±9,86 gr (minimum: 20,0 gr; maksimum: 678,0 gr) olarak belirlenmiştir. Boy–ağırlık ilişkisi; W = 0,023L2,96, Von Bertalanffy denklemi; $L _t =51.77\lfloor 1-e^{-0.049(t+5.955)} \rfloor$ ve kondüsyon faktörü 1,71 olarak hesaplanmıştır.

Some growth parameters of scorpion fish (Scorpaena porcus linneaus, 1758) in Dardanelles

Some growth parameters of scorpion fish (Scorpaena porcus Linneaus, 1758) in Dardanelles. In order to investigate the relationships among age, length and weight parameters of scorpion fish (Scorpaena porcus Linneaus, 1758) in Çanakkale region, 168 fish were sampled between the period of April 2000 and March 2001. According to the determination of fish age by using otolits, the age of fish ranged from I to X years and almost 92.3% of the samples were I and VI year-old fish. The mean length of fish was 21.22±0.89 cm (min: 10,5 cm; max: 32,0 cm) and the mean weight was 163.72±9.86 g (min: 20.0 g; max: 678.0 g). The relationship of length-weight was estimated as W= 0.023L2.96, Von Bertalanffy equation was $L _t =51.77\lfloor 1-e^{-0.049(t+5.955)} \rfloor$ and the condition factor was 1.71.
