The possibility of replacing fish meal with fermented soy pulp on the growth performance, blood biochemistry, liver, and intestinal morphology of African catfish (Clarias gariepinus)

Abstract The development of plant ingredients as an alternative to fish meal (FM) has received sustained interest in the aquaculture sector. The study investigated the replacement of FM with different percentages of dietary fermented soy pulp (FSP) to assess the growth performance, haematology, blood biochemical, liver, and gut morphology of African catfish. Five isonitrogenous (32 % crude protein) diets were prepared with FSP by replacing 0 % FSP (D1), 25 % FSP (D2), 50 % FSP (D3), 75 % FSP (D4) and 100 % FSP (D5) of FM component of the diets. The results showed a significant difference (p
