Evaluation of Anchovy as a Feed for Turbot (Psetta Maeotica)

Abstract

In this study, the effects of feeding young turbot (Psetta maeotica) with either dry pellet (50% crude protein and 18% crude oil), fresh anchovy (Engraulis encrasicholus; 20.8% crude protein and 9.2% crude oil) or combination of both on growth and feed efficiency rate (FCR) were investigated. A total of 90 turbot fry (15 fish per tank) with a mean of initially weight of 41 g were used. At the end of 45 day, the mean weights of fish with dry pellet (PL), fresh anchovy (HS) or combination of both (HP) were 62,30 +/- 2,22 g, 63,54 +/- 1,89 g and 62,90 +/- 0,89 g, respectively. No significant differences were observed among treatments (P > 0.05). Daily food consumption (g dry feed/g fish weight) and FCR (g dry feed/g weight gain) values for as follows: 0,77 +/- 0,01 ve 0,86 +/- 0,07for PL, 0,78 +/- 0,01 ve 0,82 +/- 0,09 for HP, and 0,75 +/- 0,02 ve 0,79 +/- 0,06 for HS. There were no differences between any treatments (P > 0.05). Our findings indiciated that of feedings turbot with HP, PL and HP had similar effects on growth and FCR. Turbot can be fed either dry pellet or fresh anchovy or combinating of both.
