| Sumario: | The effect of probiotic actinobacteria and homeopathic medicines, as well as their combination, on the physiological condition of early juveniles of American oyster Crassostrea virginica during their nursing in a commercial oyster laboratory was evaluated for 30 days. Five treatments were included in the experimental design: [T1 (Streptomyces sp. RL8), T2 (ViP 7C + VIA 7C), T3 (PhA 7C + SIT 7C), T4 (ViP 7C + VIA 7C + RL8), T5 (PhA 7C + SIT 7C + RL8)] and two controls: [T6 (Ethanol) and T7 (Distilled Water)], with three replicates each. As physiological response variables, the Digestive Gland Index (IGD) and the Muscular Index (MI) were evaluated. At the end of the bioassay (T30), a higher average value of the IGD was observed in juveniles that received the treatments T3, T4 and T5, as well as differences in relation to the MI, with maximum values in juveniles that received T3, T5, and T6. These results demonstrate that the use of probiotic actinomycetes and homeopathic medicines has productive applicability to improve the physiological condition and performance in C. virginica, with a positive potential effect on their biological and economic performance during hatchery-nursery stage and sea farming. |
