Boy-ağırlık ilişkisi verileri, türlerin populasyonlar ve habitatlar arasında karşılaştırılmasına yardımcı olan önemli temel bilgilerdir. Bu çalışmada, kuzeydoğu Akdeniz'de bulunan İskenderun Körfezi’nden Lagocephalus guentheri'nin boy-ağırlık ilişkileri ve kondisyon faktörleri hakkında ayrıntılı bilgiler sunuyoruz. Toplam 408 örnek (262 Dişi, 146 Erkek), Aralık 2022 ile Aralık 2023 tarihleri arasında İskenderun Körfezi'nden yerel balıkçılar tarafından ticari trol tekneleriyle toplanmıştır. Toplam boy aralığı dişiler ve erkekler için sırasıyla 11.0-36.9 cm ve 11.2-36.7 cm’dir. Dişilerin ve erkeklerin toplam ağırlıkları sırasıyla 20.30-1080.50 g ve 20.50-1012.36 g arasında değişmektedir. L. guentheri'nin boy-ağırlık ilişkisi dişiler için W = 0,0098 × L3.2145 (R2 = 0.9960), erkekler için W = 0.009 × L3.2399 (R2 = 0.9963) ve her iki cinsiyet için W = 0.0095 × L3.2243 (R2 = 0.9962) olarak hesaplanmıştır. Fulton'un kondisyon faktörü dişiler için 1.2384, erkekler için 1.2504 ve her iki cinsiyet için 1.2335 olarak gözlemlenmiştir. Bu çalışma, tür tanımlamasının düzeltilmesinden sonra L. guentheri için boy-ağırlık ilişkileri ve kondisyon faktörleri üzerine en yeni referanstır. Akdeniz ekosisteminde ekolojik dengenin yeniden sağlanması için yapılacak çalışmalara ışık tutması açısından balon balığı türlerinin popülasyon parametrelerinin belirlenmesi oldukça önemlidir. Bu çalışma, Akdeniz'deki balıkçılık bilimcileri ve yöneticileri için faydalı olacak temel bilgileri sağlayacaktır.

Length-Weight Relationship of Diamondback puffer Lagocephalus guentheri from the northeastern Mediterranean Sea

Öz

The length-weight relationship data is important basic information that helps to compare species between populations and habitats. In this study, we provide detailed information on the length-weight relationships and condition factors of Lagocephalus guentheri from the Iskenderun Bay, northeastern Mediterranean Sea. A total of 408 (262 Female, 146 Male) specimens were collected on commercial trawlers by local fishermen caught between December 2022 to December 2023 from Iskenderun Bay. The total length range was 11.0-36.9 cm and 11.2-36.7 cm for females and males, respectively. The total weight values of females and males ranged from 20.30-1080.50 g and 20.50-1012.36 g, respectively. The length-weight relationship of L. guentheri was calculated as W = 0.0098 × L3.2145 (R2 = 0.9960) for females, W = 0.009 × L3.2399 (R2 = 0.9963) for males, and W = 0.0095 × L3.2243 (R2 = 0.9962) both sexes. The Fulton’s condition factor was observed as 1.2384 for females, 1.2504 for males, and 1.2335 for both sexes. This study is the most recent reference on length-weight relationships and condition factors for L. guentheri after correction of species identification. It is very important to determine the population parameters of pufferfish species to shed light on the studies to be carried out to restore the ecological balance in the Mediterranean ecosystem. This study will provide basic information that will be useful for fisheries scientists and managers in the Mediterranean Sea.
