ABSTRACT Arapaima gigas, an endemic fish species of the Amazon region, is characterized by rapid growth and acceptance of artificial feed despite being carnivorous. In fish farms, when submitted to stressful conditions, this fish is susceptible to various diseases. There is evidence that the health and zootechnical performance of farmed aquatic animals can be improved by the prophylactic use of probiotics. Therefore, this study aimed at investigating growth, physiology and stress resistance of A. gigas (35.22 ± 2.25 g) fed diets supplemented with commercial probiotic mix additive containing Bacillus subtilis, Enterococcus faecium, Lactobacillus reuteri and Pediococcus acidilactici (Aquastar®), at four concentrations: 0, 1, 5, or 10 g of Aquastar® per kg of diet. The daily growth index was higher in fish fed 10 g of probiotic mix per kg of diet. No changes were observed in hematocrit and hemoglobin. The albumin:globulin ratio increased in fish receiving 1 and 5 g probiotic mix, but significantly decreased in stressed fish fed 1 g kg⁻¹ due to reduced albumin and increased total protein levels. Plasma total cholesterol and triglyceride levels decreased, and leukocytes number increased in A. gigas that received the probiotic mix, indicating beneficial effects on the immune system and health of this fish species. This is the first study providing hematological and biochemical parameters of A. gigas fed with probiotic mix additive supplement diets. Our results indicate that A. gigas, particularly when supplemented with 10 g kg-1 of commercial multi-cepa probiotic mix, presented improved growth, health and stress resistance.
