Assessment of the growth response of African catfish Clarias gariepinus fed varying levels of mice (Mus musculus) meal by substituting fishmeal

A 56-day growth research was carried out to assess the suitability of adding processed micemeal (Mus musculus) as the protein source in the diet of Clarias gariepinus fingerlings (average weight 2.05±0.11). Ten fish were placed in circular pools with a capacity of sixteen liters each and designated as treatments one to five, with one replication for each treatment. Four test diets were created with micemeal inclusion levels of 30%, 50%, 70%, and 100%, respectively, replacing equal proportion of fishmeal from the control diet with 35% crude protein. Standard procedures were used to determine water quality parameters such as temperature, pH, total alkalinity, free carbon dioxide, and dissolved oxygen. Except for dissolved oxygen, which ranged from 4.10 to 4.37 mg/l, all metrics fell within an acceptable tolerance range for fish culture. The fingerlings accepted the experimental meals. Significant differences (p
