Partial or total replacement of dietary fish oil with alternative lipid sources in silvery-black porgy (Sparidentex hasta)

An eight-week feeding trial was conducted to evaluate the effects of partial (50%) or total (100%) replacement of dietary fish oil with alternative lipid sources in silvery-black porgy. Seven isonitrogenous (50%) and isolipidic (20%) experimental diets were formulated namely: FO (fish oil), CO (cano...

Description
Summary:An eight-week feeding trial was conducted to evaluate the effects of partial (50%) or total (100%) replacement of dietary fish oil with alternative lipid sources in silvery-black porgy. Seven isonitrogenous (50%) and isolipidic (20%) experimental diets were formulated namely: FO (fish oil), CO (canola oil), SO (sunflower oil), T (tallow), FC (fish oil+canola oil, 50:50), FS (fish oil+sunflower oil, 50:50) and FT (fish oil+tallow, 50:50). Fish fed the T and FT diets statically had lower final weight, weight gain and specific growth rate than other groups (P
