Effect of different levels pistachio hull (Pistacia vera) on the growth and some biochemical and hematological properties of rainbow trout (Oncorhynchus mykiss)

The effect of pistachio green hull (PGH) at 0, 1.5, 4.5, 13.5 and 27% of the diet on the growth, blood biochemical and hematological parameters of rainbow trout (Oncorhynchus mykiss) of 27.03±0.58 g was investigated in a completely randomized design and in three replications with 14 fish individuals in each. At the end of 8 weeks feeding trial, blood samples were randomly taken from 4 individulas in each replication. Results showed significant differences (p0.05) were observed among treatments. Tp (2.76±0.15 g/dl), LDH (2139±44.26 IU/l), ALP (331.9±21.4 IU/l), GPT (407±17.82 IU/l), Hb (8.73±0.7 g/dl) and Hct (33.33±2.28%) had significant differences in group receiving 27% PGH compared with other group (p
