Assessment of Toxicities of Inorganic Fertilizers on Clarias gariepinus Juveniles Towards Attaining SDG No. 2 and No. 14

This study evaluated the effect of acute toxicity of three commercial inorganic fertilizer NPK 15:15:15, NPK-1; NK 20:20:20, NPK-2; urea and Single super phostate on Clarias gariepinus juveniles in static condition. The concentration of NPK-1, NPK-2, urea and single superphosphate that killed 50% of the African Catfish with 96-h LC50 were 6.25g/l, 7.25g,/l, 16.25 and 12.50g/l, respectively. For water quality parameters, there was no significant difference (p<0.05) in the mean of (temperature, Ph and alkalinity, while there was significant difference (p<0.05) in Dissolve oxygen. However, urea treatment parameters were found to have highest numerical value among the treatments in the water treatment parameters. Furthermore, there was significant difference (p<0.05) in the water treatment parameters. Furthermore, there was significant difference (p<0.05) in the haemoglobin percentage among the treatments while no significant difference (p
