Agrimin and Fishmin are used as supplementary diets in many districts of Andhra Pradesh for
effective fish culture. Since the current study is aimed at studying the effect of selected
Supplementary feeds on fish productivity aspects, yield profiles and metabolic aspects of selected
cultivable fishes, Hypophthalmichthys molitrix, Cyprinus carpio, tenopharyngodon idella, such as
total proteins, free amino acids and the activities of ALAT/AAT/GDH were studied. Agrimin or
fishmin treatment enhanced in the all metabolic aspects which were selected for the study and all the
changes were found to be statistically significant over their corresponding control values. The
muscle and liver of the control H.molitrix appeared to possess more proteins compared to other two
species. The agrimin and fishmin fed fish species muscle and liver showed more percent elevations
of their total protein content and the changes were found to be statistically significant over the
control. Identical trends were also obtained for the muscle and livers free amino acid content.
Agrimin or fishmin treatment enhanced the fish muscle and liver protease content and all the
changes were found to be statistically significant over their corresponding control values. Liver
tissue showed more AAT / ALAT/GDH levels. Agrimin and Fishmin fed fishes muscle and liver
showed an increase in their AAT, ALAT and GDH activity levels. The muscle and liver tissues of the
control feed fed fish batch appeared to possess higher AAT / ALAT/GDH levels compared to other
species of fishes selected for the study.
