Weight gain

Effect of feeding frequency and feeding rate on the growth and feed efficiency of catfish, Heterobranchus bidorsalis fry in outdoor concrete ponds

The effect of feeding frequency on the growth and feed efficiency of Heterobranchus bidorsalis was investigated at two feeding rates (10% and 40% of body weight) in a 2x2 factorial experiment. The study was conducted in twelve 2x2x1m outdoor concrete ponds supplied with aeration with three replicate ponds for each treatment. Fish averaging 80 ± 4.5 mg were fed either two times or four times daily at two different feeding rates using practical diets for ten weeks. The percentage weight gain ranged from 55.25% to 95.13%.
