Abstract

Sand smelt (Atherina boyeri Risso, 1810) meal (SSM) was tested to replace fish meal (FM) in practical diets for carp fry, Cyprinus carpio L., 1758. Triplicate groups of fish were fed each of five isonitrogenous (38%), isolipidic (10%) and isoenergetic (3750 kcal DE g-1) diets formulated in which SSM replaced 0.0, 25, 50, 75, and 100% of the protein supplied by FM. Twenty five fish fry were placed in each of the aquarium (65 L) and each diet was fed manually to apparent satiation twice daily for three months. At the end of the experiment, there was determined to live weight, condition factor, hepatosomatic index, and visscerosomatic indeks of experimental groups. The results indicate that fish fed SSM up to 75% exhibited better growth values (P<0.05) than those fed the others. At the end of the experiment, there were no significant (P>0.05) differences in the hepatosomatic index (HSI) among groups following inclusion of SSM in fish diet. The findings of the examination of the liver verified that it has been observed normal lipid accumulation in hepatosit cells, bile channels, hepatopancreatic cell groups, partly connective tissue and existence of blood vessels instead of lipid degeneration. Results of the present study appear to indicate that replacement of commercial fish meal with sand smelt meal in diets has no adverse effects on growth and liver histology of carp fry according to the histological data similar with HSI.

Özet

Aynalı sazan (Cyprinus carpio, L.,1758) yavru yeminde gümüş balığı (Atherina boyeri Risso, 1810) ununun %0.0, 25, 50, 75 ve 100’lük oranlarda ticari balık unu yerine kullanılarak protein (%38), yağ (%10) ve enerji (3750 kcal SE g-1) düzeyleri benzer hazırlanmış beş farklı rasyon ile yavrular 90 gün süreyle beslenmiştir. Denemede, her birinde 25 yavru bulunan 65 litrelik 15 akvaryumda, üç tekrarlı olarak gerçekleştirilmiştir. Buna göre deneme gruplarında büyüme, kondisyon faktörü, hepatosomatik indeks ve visserosomatik indeks değerleri belirlenmiştir. Elde edilen sonuçlara göre %75’e varan oranda balık unu yerine gümüş balığı unu ilave edilmiş rasyonların yavruların büyümesini olumlu yönde etkilemiştir (P 0.05). Karaciğerin yapılan incelemelerinden edinilen bulgular da bunu doğrulamakta olup; bir yağ dejenerasyonu yerine hepatosit hücrelerinde olağan yağ birikimi, safra kanalları, hepatopankreatik hücre grupları ile yer yer bağ doku ve kan damarlarının varlığı gözlemlenmiştir. Elde edilen HSI bulgularına paralellik gösteren histolojik bulgulara göre gümüş balığı ununun ticari balık unu yerine kullanımının sazan yavrusunun büyümesi ve karaciğer histolojisi açısından olumsuz bir etkisinin olmadığı sonucuna varılmıştır.
