Effects of extruded pellet and moist pellet on growth performance, body composition, and hematology of juvenile olive flounder, Paralichthys olivaceus

Abstract A feeding trial was conducted to evaluate the effects of two different sizes of extruded pellets (EP) (EP1 - 3 mm or EP2 - 5 mm) and a moist pellet (MP) in olive flounder, Paralichthys olivaceus, reared in semi-recirculation system. A total of 450 fish with an average initial weight of 5.0 ± 0.2 g (mean ± SD) were fed one of the three experimental diets in triplicate groups. At the end of a 6-week feeding trial, weight gain, specific growth rate, and feed efficiency of fish fed EP diets were significantly higher than those of fish fed MP (P
