İskenderun Körfezi’nde (Doğu Akdeniz, Türkiye) Yayılım Gösteren Lesepsisyen Saurida undosquamis Türünün Boy-Boy ve Boy-Ağırlık İlişkileri

Öz

Bu çalışmada, Doğu Akdeniz (Türkiye)’de yayılış gösteren Saurida undosquamis türünün boy-boy ve boy-ağırlık ilişkileri incelenmiştir. Balık örneklerinin boyları ve ağırlıkları sırasıyla 0.01 gr ve 0.01 cm hassasiyetle kayıt altına alınmıştır. Çalışmamızda S. undosquamis türünün boy ve ağırlık değerleri bakımından t-testi sonuçlarına göre cinsiyetler arasında istatistiksel manada bir farklılık olduğu (P<0.05) için dişi ve erkek bireyler ayrı ayrı değerlendirilmiştir. S. undosquamis türünün dişi, erkekler ve tüm bireyler için boy-ağırlık ilişkisi denklemleri sırasıyla W=0.0023TL3.330; W=0.0014TL3.487 ve W=0.0020TL3.366 olarak hesaplanmıştır. Boy-ağırlık ilişki denklemindeki “b” değerinin 3’ten istatistiksel olarak farklı olduğu belirlenmiştir (P<0.05). Yapılan analiz sonucunda, S. undosquamis bu habitatta pozitif allometrik bir büyüme gösterdiği belirlenmiştir. S. undosquamis’in boy-boy ilişkileri incelendiğinde belirleme katsayılarının 0.98 ile 0.99 arasında değiştiği ve istatistiksel olarak anlamlı oldukları belirlenmiştir (P<0.001). Bu çalışma balık stoklarının sürdürülebilirliğini sağlamak için gerekli bilginin sağlanmasında yardımcı olabilir.

Length-Length and Length-Weight Relationships of Lessepsian Saurida undosquamis from the İskenderun Bay (Eastern Mediterranean, Turkey)

Öz

In this study, the length-length and length-weight relationships were investigated for Saurida undosquamis from the Eastern Mediterranean Sea (Turkey). All fish sample lengths and weights were recorded to the nearest 0.01 g and to 0.01 cm, respectively. According to t-test results, there were statistically significant differences between sexes in terms of length and weight (P<0.05) for S. undosquamis; therefore, female and male samples were separately evaluated in the current study. The length-weight relationship equations of S. undosquamis were calculated as W=0.0023TL3.330; W=0.0014TL3.487 and W=0.0020TL3.366 for females, males, and all individuals, respectively. It was found that the “b” value in the length-weight relationship equation was statistically different from 3 (P <0.05). As a result of the analysis, it was determined that S. undosquamis showed positive allometric growth in this habitat. When the length-length relationships of S. undosquamis were examined, they were found that the coefficients of determination ranged from 0.98 to 0.99 and they were also highly significant (P<0.001). This study can help provide the necessary information to ensure the sustainability of fish stocks.
