Gill histopathology in cultured sea bass (Dicentrarchus labrax (L.) coinfected by Diplectanum aequans (Wagener, 1857) and Lernanthropus kroyeri (van Beneden, 1851)
Abstract
Because of a 1.5% daily mortality was recorded in sea bass (Dicentrarchus labrax) reared in floating-cage farm in Aegean Sea coast of Turkey, 15 sea bass were examined parasitologically and pathologically, in March 2010. Diplectanum aequans (Wagener, 1857) and Lernanthropus kroyeri (van Beneden, 1851) were detected in all fish. Of the 15 sea bass dissected, 100% were infected by Diplectanum aequans (Wagener, 1857), and mean intensity of infection was 31.9, 100% were infected by Lernanthropus kroyeri (van Beneden, 1851) and mean intensity of infection was 11.4, respectively. In the pathological examination of the gills, anemia, whitish mucuoid exudate and greenish egg sac belong to female Lernanthropus were observed. Histologic examinations indicated, both Diplectanum aequans and Lernanthropus kroyeri were present on branchial lamellae in the gills of all fishes.Lamellary edema formation, fusion of the secondary lamellae and necrosis in both primary and secondary lamellae due to parasitic irritation were determined. As a result, it was concluded that fish deaths were occurred due to the lesions formed after dense infestations of Diplectanum aequans and Lernanthropus kroyeri

Kültür levreklerinde (Dicentrarchus labrax, L.) Diplectanum aequans (Wagener, 1857) ve Lernanthropus kroyeri (van Beneden, 1851) miks enfeksiyonunda solungaç histopatolojisi
Abstract
2010 yılı Mart ayında, günlük %1.5 mortalite gözlenen, Ege Bölgesi’nde yüzer ağ kafeslerde yetiştiriciliği yapılan kültür levrek çiftliğinden alınan 15 levreğin parazitolojik ve patolojik incelemesi yapıldı. Balıkların tamamında Diplectanum aequans (Wagener, 1857) ve Lernanthropus kroyeri (van Beneden, 1851) parazitleri saptandı. Incelenen 15 levrek balığının sırasıyla; Diplectanum aequans (Wagener, 1857) ile %100 oranında enfekte ve ortalama enfeksiyon yoğunluğunun 31.9, Lernanthropus kroyeri (van Beneden, 1851) ile ise %100 oranında enfekte ve ortalama enfeksiyon yoğunluğunun 11.4 olduğu belirlendi. Patolojik incelemede, solungaçlarda anemi, beyaz mukoid eksudat ve dişi Lernanthropus’a ait yeşilimsi renkte yumurta keselerine rastlandı. Mikroskobik incelemede, tüm balıkların solungaç lamelleri üzerinde hem Diplectanum aequans’a hem de Lernanthropus kroyeri’ne rastlandı. Parazitlerin etkisine bağlı olarak lamellar ödem, sekonder lamellerde füzyon ile primer ve sekonder lamellerde nekroz gözlendi. Sonuç olarak, balıklardaki ölümlerin, Diplectanum aequans ve Lernanthropus kroyeri parazitlerinin yoğun enfestasyonu sonucu oluşan lezyonlardan kaynaklandığı kanısına varıldı
