Comparative study on dietary protein requirements for juvenile and pre-adult gibel carp (Carassius auratus gibeliovar. CAS III)
Two 8-week growth trials were conducted in indoor recirculation system to evaluate the protein requirements for juvenile (3.70 +/- 0.20g) and pre-adult (85.2 +/- 0.70g) gibel carp, Carassius auratus gibelio var. CAS III. Six isoenergetic diets were formulated for each trial using fish meal and casei...
