A total of 579 specimens were analyzed, with F. aztecus contributing the highest sample size (238 individuals), followed by P. semisulcatus (214) and M. monoceros (127). Carapace length (CL) and weight (W) measurements revealed interspecies differences. The average carapace length was 5.66 mm for F. aztecus, 6.63 mm for P. semisulcatus, and 5.08 mm for M. monoceros. Average weights were 32.81 g, 39.68 g, and 31.48 g, respectively. Growth patterns, determined by the parameter 𝑏, showed distinct gender differences. Females generally exhibited negative allometric growth, while males displayed either isometric or positive allometric growth, depending on the species. Statistically significant differences in growth types were observed, particularly in M. monoceros males (p < 0.05). These results provide crucial insights into the population dynamics and ecological adaptations of shrimp in İskenderun Bay. The findings contribute to understanding the species’ growth characteristics, supporting the development of sustainable fisheries management strategies in the region. KW - Trammel net fishing KW - shrimp growth patterns KW - gender-based growth differences KW - Iskenderun Bay N2 - Bu çalışmada, Ekim 2023 ile Kasım 2024 arasında toplanan veriler kullanılarak, Kuzeydoğu Akdeniz'deki İskenderun Körfezi'nde ekonomik açıdan önemli üç karides türünün (Farfantepenaeus aztecus, Penaeus semisulcatus ve Metapenaeus monoceros) uzunluk-ağırlık ilişkileri (LWR) araştırılmıştır. Toplam 579 örnek analiz edilmiş olup, F. aztecus en yüksek örneklem büyüklüğüne (238 birey) katkıda bulunmuş, ardından P. semisulcatus (214) ve M. monoceros (127) gelmiştir. Kabuk uzunluğu (CL) ve ağırlık (W) ölçümleri türler arası farklılıkları ortaya koymuştur. Ortalama kabuk uzunluğu F. aztecus için 5,66 mm, P. semisulcatus için 6,63 mm ve M. monoceros için 5,08 mm olarak bulunmuştur. Ortalama ağırlıklar sırasıyla 32,81 g, 39,68 g ve 31,48 g olarak bulunmuştur. 𝑏 parametresiyle belirlenen büyüme desenleri belirgin cinsiyet farklılıkları gösterdi. Dişiler genellikle negatif allometrik büyüme gösterirken, erkekler türe bağlı olarak izometrik veya pozitif allometrik büyüme gösterdi. Özellikle M. monoceros erkeklerinde büyüme tiplerinde istatistiksel olarak anlamlı farklılıklar gözlendi (p < 0,05). Bu sonuçlar İskenderun Körfezi'ndeki karideslerin popülasyon dinamikleri ve ekolojik adaptasyonları hakkında önemli bilgiler sunmaktadır. Bulgular, türün büyüme özelliklerinin anlaşılmasına katkıda bulunarak bölgede sürdürülebilir balıkçılık yönetim stratejilerinin geliştirilmesini desteklemektedir. CR - Abdul-Wahab, M. M. (2014).
