Animal by-products including Feather Meal (FTM) have shown very promising findings when included in aquaculture feeds. However, their use is limited to a few fish species only. More studies are needed to investigate the full potential of this by-product. In the present study, a total of six diets were formulated to replace fish meal protein with FTM at levels of 0%(FTM0), 20%(FTM20), 40%(FTM40), 60%(FTM60), 80%(FTM80) and 100%(FTM100). Danish fish meal was used as a sole protein source in the control diet. All diets were isonitrogenous (40% protein), isolipidic (12% lipid) and isoenergetic (380 kcal/100 g diet). The fish growth performances and feed utilization were negatively affected with the increase inclusion levels of FTM in the diets. The feed intake dropped drastically when the FTM protein inclusion levels were increased up to 40-100%. The significantly high fish mortalities and retarded growth in …
