R.  aUse of earthworm (Eisenia fetida) meal as a supplement for feeding tilapia juveniles (Oreochromis niloticus).h[electronic resource]  c2022  aAbstract: Earthworm meal comprises a class of food additives with potential to replace or supplement conventional proteins used in fish feed. Considering the potential of earthworm meal, as a protein source for fish feed, this study aimed to investigate the productive performance and the hematological profile of Nile tilapia juveniles fed with a commercial diet enriched with earthworm meal at levels (0.0; 5.0, 10 and 20%). The assay was conducted for 32 days and the productive performance and hematology profile of the animals were evaluated. Tilapia juveniles (n=144; 25.30±3.27g) were distributed in 12 aquariums (300 L) in a static system with partial water changes. The experimental design was completely randomized with four treatments and three replications. There were no significant differences (p&gt0.05) for performance responses and hematological profile related to variables on hematocrit and CHCM. However, for hemoglobin values the treatment with 20% earthworm meal was similar to the treatments with 5 and 10% earthworm meal, and significantly differed from the control treatment, suggesting its potential as a fish feed supplement. Thus, earthworm meal can be used at 5, 10, and 20% as a supplement for Nile tilapia juveniles without compromising their performance and hematological profile.  aEarthworms  aFish farms  aProtein supplements  aTilapia (common name)  aAlimentação Suplementar  aMinhoca  aNutrição Animal  aSuplemento Protéico  aTilápia Nilótica  aFish farm  aFood supplement  aHematological response  aPerformance response1 aCARDOSO, I.
