This is aimed at studying the aeration kinetics of catfish (Clarias
gariepinus) smoked directly with biogas. Five live fresh fishes (Clarias
gariepinus) were obtained from Fishery and Aquaculture Technology
Department in FUTA, Ondo State, Nigeria. The fishes were killed,
de-gutted, thoroughly washed with water, cut into pieces of 3 cm length.
The chunks were smoked with biogas and the weight was being monitored at
15 minutes interval until constant weight was observed.. The study
showed that the time taken for drying of Clarias gariepinus to reach the
humidity point of around 12.43% (db.) was two and a half hours. We
tailored the drying data to 10 thin-layer drying models. The compared
the performances of the models using the determination of coefficient
(R2), reduced chi-square (χ2) and root mean square error (RMSE) between
the detected and foreseen moisture ratios. The results showed that
Henderson and Pabis modified model was found to satisfactorily describe
the biogas drying curves of Clarias gariepinus.
