Özet

The effects on growth of juvenile crayfish (Astacus leptodactylus Eschscholtz, 1823) fed diets with different protein levels were investigated. The feed groups used in the experiment were trout feed (A), raw potato (B) and raw carrot (C). A total of 160 crayfish were used in the study with an average weight of 0.20±0.01 g and an average length of 2.06±0.03 cm. The experiment was conducted over a period of 12 weeks. At the end of the experiment, it was determined that the average weights of juvenile crayfish fed with different diets were between 0.51±0.07 and 1.18±0.17 g and the average lengths were between 2.45±0.16 and 3.33±0.18 cm. It was observed that the relative changes in length and weight increases were also different between the groups. Statistically, the difference between lengths and groups (F=21.59; p
Farkli protein seviyelerindeki yemlerle beslenen yavru kerevitlerin (Astacus leptodactylus Eschscholtz, 1823) büyüme üzerine etkileri incelenmistir. Denemede kullanilan yem gruplari; alabalik yemi (A), çig patates (B) ve çig havuç (C)’dir. Çalismada toplamda 160 kerevit kullanilmis olup, ortalama agirliklari 0,20±0.01 g, ortalama boylari 2,06±0.03 cm olarak ölçülmüstür. Deneme 12 haftalik bir sürede yürütülmüstür. Farkli diyetlerle beslenen yavru kerevitlerin deneme sonunda ulastiklari agirlik ortalamalari 0.51±0.07 ile 1.18±0.17 g arasinda, ortalama uzunluklari ise 2.45±0.16 ile 3.33±0.18 cm arasinda oldugu belirlenmistir. Boy ve agirlik artislarindaki degisim göreceli olarak da gruplar arasinda farkli oldugu görülmektedir. Istatistiki olarak; boylar ve gruplar arasinda (F=21.59; p
