Author(s): Ursula Odo, Iyikite Ebuka, F Chijioke and GE Odo*
The present study investigated the morphometric indices and oxidative stress biomarkers of African Catfish Clarias gariepinus juveniles exposed to agricultural fungicide mancozeb. A total of 150 Clarias gariepinus with standard length and weight that ranged from 9.8 cm to 17.5 cm and 11 g to 55 g respectively were used for the experiment. The 96hours LC50 value of Mancozeb on Claria s gariepinus juveniles was estimated to be 410.90mg/L. The sub-lethal four treatments were exposed to 0.00. 20.55, 41.09 and 82.18 mg/L (A-D) Mancozeb fungicide. Each group were replicated three times consisting of 10 fish per replica summing up to 30 fish. The physico-chemical parameters of water observed for five weeks showed changes and fluctuations on temperature range from 28°C to 32°C, pH levels ranged from 7.3 to12.3, Alkalinity range 0.88 to 4.10mg/L, CO2 values ranged from 3-12.5mg/L.
