The present study investigated the effect of the aqueous extract of the Mansoa alliacea ajo sacha leaf on the growth, productive performance and bromatological composition of Colossoma macropomum fry. The research was carried out at the facilities of the Piscigranja Experimental Pilot Center - Quistococha UNAP, from September to November 2022. A total of 600 fingerlings were distributed in 12 pens of 50m2 (1 fish/m2) and fed for 90 days with balanced food enriched with aqueous extract of Mansoa alliacea (0 mL/kg, 4 mL/kg, 8 mL/kg and 12 mL/kg), with a frequency of 2 times a day and feeding rate of 6% (two months) and 3% (two months). two months). Every 15 days, the weight and length of the fry were recorded to determine growth in weight (g) and total length (cm) and zootechnical indices (daily weight gain, biomass gained, specific growth rate, apparent feed conversion index). and surviva...
