The Possibility of Partial Replacement of Olive Pomace with Some Dietary Items of Rainbow Trout (Oncorhynchus mykiss Walbaum, 1792)

This study investigated effects of different levels of dietary olive oil pomace on body composition, growth performance, hematological factors and sensory analysis of rainbow trout. Six practical diet containing 0 (control), 2, 4, 6, 8 and 10% olive pomace were formulated and supplied to fish with an average body weight of 184.7 g being allocated randomly to rectangular concrete ponds. Water flow was 10 L S-1. Temperature and pH were 10±3°C and 6.8-7.9, respectively. Fish were fed by hand ad libitum three times a day. At the end of the experiment, eviscerates and beheaded body composition and growth performance were not affected by difference levels of olive pomace (P > 0.05). However, hematological parameters were significantly affected by increasing olive oil pomace (P
