Abstract:

 

The effects of the Pelargonium sidoides extract on survival, growth, and body composition of juvenile freshwater  crayfish (Astacus leptodactylus) were investigated. Newly hatched third instars of A. leptodactylus were fed with experimental  diets prepared by using supplementation of P. sidoides extract (0, 0.5, 1 and 2 ml 100 g-1) for 105 days. Growth rate was  increased significantly in crayfish fed with 2 ml P. sidoides extract 100 g-1 diet in comparison to the control groups (P<0.05).  Feed conversion ratio, protein efficiency ratio and apparent net protein utilization were also significantly improved in group  fed diet with 2 ml 100 g-1 P. sidoides extract than that with control and the other groups. After 105 days of rearing the survival  rate was found highest in 2 ml P. sidoides extract 100 g-1 diet supplemented group (80.0%). Protein content (16.5 %) of the 2  ml 100 g-1 P. sidoides extract-supplemented group was significantly higher than the control and other dietary groups  (P<0.05). The lipid contents were decreased in P. sidoides extract-supplementation. These results indicated that the P.  sidoides extract is useful to improve growth, feed utilization and survival rate in freshwater crayfish, juvenile diets. 	 	 		 .
