The aim of this study was to investigate the combined effects of two stocking densities (650 and 1300 juveniles/m2 ) and diets (live feed - Daphnia magna and commercial trout feed) on survival rate and growth performance of Astacus leptodactylus juveniles. Juveniles in the second developmental stage were used in the experiment. Final survival rate and growth paremeters of juveniles were evaluated at the end of experiment (90 days). The results of this study indicated that diets were not found effective on survival rates, though increasing stock densities reduced survival rates. The best final survival rate as 21.99 %, was achieved in the group fed with live feed and kept under the 650 juveniles/m2 stocking density, whereas the lowest survival rate values as 10.84 % was obtained in the group fed with trout pellet and kept under the 1300 juveniles/m2 stocking density. At the end of experiment, the highest final body weight was found in group of at 650 juveniles/m2 stocking density and fed with trout feed. The result of our study also revealed that stocking density had a significant effect on survival rates of crayfish juvenile fed with both feeds.

Bu çalışmada, iki farklı yem
(canlı yem-Daphnia magna ve ticari
alabalık yemi) ve stok yoğunluğunun (650 ve 1300 juvenil/m2) Astacus leptodactylus yavrularının
hayatta kalma ve büyüme performansı üzerine kombine etkileri araştırılmıştır.
Denemede II. dönem yavrular kullanılmıştır. Deneme sonunda, yavruların hayatta
kalma ve büyüme parametreleri değerlendirilmiştir. Bu çalışmanın sonuçları,
diyetlerin hayatta kalma oranları üzerinde etkili olmadığını, ancak artan stok
yoğunluğunun yaşama oranlarını azalttığını göstermiştir. En iyi yaşama oranı %
21,99 olarak 650 juvenil/m2 stok yoğunluğunda canlı yemle beslenen
grupta sağlanırken, en düşük yaşama oranı ise % 10,84 olarak 1300 juvenil/m2
stok yoğunluğunda alabalık yemi ile beslenen grupta elde edilmiştir. Denememe
sonunda en yüksek vücut ağırlığı, 650 juvenil/m2 stok yoğunluğunda
alabalık yemi ile beslenen grupta bulunmuştur. Çalışmamız sonucunda ayrıca, yavru kerevit
beslenmesinde her iki yem ile beslenen yavrularda hayatta kalma oranları
üzerinde stok yoğunluğunun önemli bir etkiye sahip olduğu görülmüştür.
