More than half of the nutrients sustaining the optimal plant growth in the aquaponic system are derived from fish waste

More than half of the nutrients sustaining the optimal plant growth in the aquaponic system are derived from fish waste. However, the use of fish meal and nitrogen, phosphorus, potassium (NPK) fertilizer in promoting growth parameters of the plant and for some fish species in such a system is not well documented. This study aimed to examine the effect of NPK fertilizer on the growth performance of Tinfoil barb (Barbonymus shcwanefeldii), a common riverine species as well as Chinese broccoli...
