Abstract:

The effect of cow dung, chicken manure and NPK on the production of Oreochromis niloticus was investigated in earthen ponds which were prepared thus: no liming, no fertilization (NL/NF), liming and fertilization with cow droppings (L/Cow), liming and fertilization with chicken droppings (L/Chick) and liming and fertilization with NPK (L/NPK). Best fish growth was recorded in the limed, NPK–fertilized (L/NPK) ponds while productivity values (Gross and Net) were highest in the limed, chicken droppings fertilized (L/Chick) ponds. Growth parameters decreased with age of fish while significant differences (P<0.05) were observed between treatments.
