drying at different temperatures, air velocities, drying time and mass of fish in dryer, reporting that at 0.3 m/s, 6 h and 15 min and 50 kg a good quality product is achieved, providing that the average solar flux is about 700 W/m2 and the ambient tem- perature outside the dryer about 40 °C. Jain (2006) evaluated the convective heat and mass transfer coefficient for chelwa fish under solar drying and developed a mathematical model for predicting the drying parameters
