Abstract

This study determines the meat yield (MY) efficiency of three commercially important deep-water shrimp species (Parapenaeus longirostris, Plesionika martia, and Plesionika heterocarpus) caught in the Eastern Aegean Sea (Sığacık Bay, Türkiye). A total of 1103 individuals were sampled monthly between May 2008 and April 2009. After excluding damaged and juvenile specimens, 1092 individuals were analyzed. Meat yield was calculated as the percentage of edible tail muscle weight relative to total body weight. The results showed significant interspecific differences: P. longirostris exhibited the highest mean meat yield (44.91% ± 0.28), followed by P. martia (42.20% ± 0.35), while P. heterocarpus had the lowest yield (33.99% ± 0.41). Seasonally, yield values were generally higher during the winter and spring months. These findings provide essential data for the seafood processing industry and fisheries management in the region, suggesting that P. longirostris and P. martia offer higher processing efficiency compared to P. heterocarpus. Although the dataset predates recent environmental changes in the Eastern Aegean Sea, the results provide a robust baseline reference for long-term comparisons and bio-economic assessments of deep-water shrimp fisheries.

Özet

Bu çalışma, Doğu Ege Denizi’nde (Sığacık Körfezi, Türkiye) avlanan ticari öneme sahip üç derin su karides türünün (Parapenaeus longirostris, Plesionika martia ve Plesionika heterocarpus) et verimi (MY) etkinliğini belirlemektedir. Aylık olarak yapılan örnekleme çalışmalarında Mayıs 2008 ile Nisan 2009 arasında toplamda 1103 birey örneklenmiştir. Zarar görmüş ve juvenil bireyler çıkarıldıktan sonra 1092 birey analiz edilmiştir. Et verimi, yenilebilir kuyruk kası ağırlığının toplam vücut ağırlığına yüzde oranı olarak hesaplanmıştır. Sonuçlar türler arasında belirgin farklılıklar göstermiştir: P. longirostris en yüksek ortalama et verimini (%44.91 ± 0.28) sergilerken, bunu P. martia (%42.20 ± 0.35) takip etmiş, P. heterocarpus ise en düşük verimi (%33.99 ± 0.41) sergilemiştir. Mevsimsel olarak, verim değerleri genellikle kış ve ilkbahar aylarında daha yüksek bulunmuştur. Bu bulgular, bölgedeki deniz ürünü işleme sektörü ve balıkçılık yönetimi için önemli veriler sunmakta olup, P. longirostris ve P. martia türlerinin P. heterocarpus türüne kıyasla daha yüksek işleme verimliliği sunduğunu göstermektedir.
