Effects of dietary protein level on growth and ammonia excretion of leopard coral grouper, plectropomus leopardus(Lacepede, 1802)

The effects of dietary protein level on the growth performance and ammonia excretion of the leopard coral grouper, Plectropomus leopardus were investigated for eight weeks. Fish were fed diets with 40, 45, 50, 55 and 60% crude protein levels in separate recirculating systems. Fish fed with the 50% c...
