Effect of raw anchovy as wet feed on growth performances and production cost of rainbow trouth (Oncorhynchus mykiss) during winter season in the Black Sea

Abstract

The present study was conducted to determine the effect of raw anchovy (Engraulis encrasicolus L.) as wet feed on growth performance and production cost of rainbow trout (Oncorhynchus mykiss W.) reared in net pen during winter season in the Black Sea. The fish with an initial body weight of 100 g were hand fed to apparent satiation with only raw anchovy, only pellet and anchovy/pellet combination over 58 days. Final mean body weight of the groups fed anchovy and anchovy/pellet were significantly higher (P
