Five groups of Astronatus ocellatus were fed with the average mean of 0/8 gr in 90 days in aquariums 30×30×60. The amount of amino acids existing in the muscle of the fish for control treatment and treatment 4 ml/gr was compared. The result showed that there was a meaningful difference between control treatment and treatment 5 (p<0/05). The amount of Lysine, Methionine, Valine, Phenylalanine, proline, glycine, threonine, glutamic acid was respectively 14/95, 3/14, 9/54, 30/84, 7/01, 11/31, 8/74, 30/18.ml/gr of the muscle of the fish with 4 ml Cobalt chloride in 1 kg of food which was more than the other rations such as treatment ration.
