Effects of Methanol Extract of Morus alba on Hematological Parameters and Liver Histology of African Catfish (Clarias gariepinus)

Methanol extract of Morus alba Foliage (MFE) was studied to evaluate its effect on hematological parameters and liver histology of African catfish (Clarias gariepinus). The trial consisted of five diets preparation, i.e., control diet (diet 1) and four tested diets supplemented, respectively with 2 g MFE kg(-1) (MFE-2), 5 g MFE kg(-1) (MFE-5), 7 g MFE kg(-1) (MFE-7) and 9 g MFE kg(-1) (MFE-9) of Dry Matter (DM) diet. Results showed fish fed with MFE-5 and MFE-7 diets had (p<0.05) the highest RBC counts, Hb content albumin and total protein levels among other dietary groups while MIFE-9 showed the poorest RBC, albumin and total protein. Histological study indicated that fish received MIFE-9 diet showed minor degenerative changes in the liver. In conclusion, methanol extract of Met-us alba at 7 g kg(-1) of diet has no adverse impact on hematology and liver's histology in African catfish.
