The study looked into the growth and survival of common carp fingerlings in relation to Bathua (Chenopodium album) leaf meal. Over the course of 60 days, research was conducted on five different concentrations of Bathua (Chenopodium album) leaf meal. The different treatments utilized in this trial included T0 (basal diet alone), T1 (5%), T2 (10%), T3 (15%), and T4 (20%), which replaced an equivalent proportion of the basal diet. Feeding rates for fingerlings are 4% of body weight in divided doses of pellets. Morning feeding per day was carried out. The parameters of water quality during the trial were not negatively impacted by the diet supplemented with Bathua (Chenopodium album) leaf meal, and only minor differences in the parameters of water quality were observed in different treatments.

The test results showed that the water quali Chenopodium album ty ranged from 26.8 to 27.9 degrees Celsius, from 1300 to 1550 S.cm-1 in electrical conductivity, from 7.4 to 7.7 in pH, from 5.53 to 6.6 mg/l in dissolved oxygen, from 60 to 84.33 mg/l in total alkalinity, and from 371 to 440 mg/l in total hardness. The highest growth metrics during the experiment were, however, weight increase (36.290±0.710 g), percent weight gain (280.337±14.22 %), specific growth rate (1.917±0.193), and gross conversion efficiency (GCE) (0.913±0.026) in value. A food conversion ratio (FCR) of 1.160±0.050 suggests better food use when compared to other treatments.
