Food preference and growth of grass carp, Ctenopharyngodon idella (Cuvier and Valenciennes, 1844) fed some aquatic and terrestrial plants

The present study was carried out to examine 6 plants including aquatic and terrestrial plants on food preference and growth of grass carp. 7 experimental treatments with three replicates were considered. The experimental treatments were ponds containing T1: M. spicatum, T2: C. demersum, T3: A. filiculoides, T4: L. minor, T5: C. dactylon, T6: M. sativa and T7: M. Spicatum + C. demersum + A. filiculoides + L. minor + C. dactylon + M. sativa. 12 grass carps (20 g) were added to each experimental pond. After 5 months, the fish body composition was assessed. According to results, the higher values of fish weight gain rate were obtained in treatments T4 (3.13 g), T6 (2.93 g) and T1 (2.95 g) compared to other experimental groups (p
