| Abstract |
| The use of plant-based proteins as an alternative to fishmeal is becoming increasingly popular in the aquaculture industry. However, the deficiency of essential amino acids such as lysine in plant proteins can negatively affect fish growth and health. Six diets with varying lysine levels (0%, 1%, 2%, 3%, 4%, and 5% mg/kg) were created, and each experimental diet included 1% chromic oxide (Cr2O3) as a non-digestible marker. For 70 days, each diet was assigned at random to three groups of fifteen fingerlings, and feces samples were collected for analysis. The results showed that fingerlings fed a 3% lysine supplemented peanut meal-based diet exhibited the highest growth indices, such as weight gain (20g), weight gain% (317%), FCR (1.22), SGR (1.59), nutritional digestibility (crude protein;74.19%, crude fat; 70.39%, and gross energy;72.79 kcal/g,) and hematological parameters showed the best results at 2% lysine addition (RBC; 2.98 106mm-3, Hb; 7.99 g/100ml, PLT; 65.57, Ht; 32.43%). Further increases in lysine levels reduced the fish's growth performance and death rate. Therefore, adding 3% lysine to peanut meal-based diets enhances fish growth, nutrient utilization, and hematological parameters. This study demonstrates that lysine supplementation can improve the nutritional value of peanut meal-based diets for Cyprinus carpio fingerlings and has significant implications for the aquaculture industry. |
