Weaning time in Clarias gariepinus (Burchell) larvae
Aquaculture, 1989Abstract The present study attempts to assess for the African catfish, Clarias gariepinus (Burchell), the earliest possible weaning time from Artemia to crumbles of a commercial trout diet. At the onset of exogenous feeding, 24 aquaria were stocked with larvae, which were fed during varying periods with dried decapsulated cysts of Artemia ...
