This study evaluated the performance, prevalence of ectoparasites and morpho-functional response liver branchiae Nile tilapia (Oreochromis niloticus) raised on fish meal with added homeopathic complex Homeopatila 100(®) at different concentrations.Post-reversed juvenile (O. GIFT (Genetic Improvement Farmed Tilapia) strain were used in this study. The ectoparasite parasite load skin as well branchial histology. Fish randomly assigned to receive one four treatments: control, 20 mL hydroalcoholic solution (alcohol 30° GL); per kg meal; 40 or 60 meal, compared control out addition complex. There replications treatment type (16 experimental units total) a density m(3) over period 57 days. Kruskal-Wallis H test (p < 0.05) was employed analyse physical chemical parameters water for prevalence; whereas analysis variance performance. If values significant 0.05), they by Tukey's test. Multiple comparisons averages performed using Student's t 0.05).There no between groups end experiment. Significant differences mixed conditions found within treatments. hepatosomatic ratio treated significantly lower than that from group. best results occurred receiving mL/kg terms number hepatocytes/mm(2), intercellular glycogenic behaviour, rates histological changes (hyperplasia, lamella fusion telangiectasia) percentage neutral acidic mucin-producing cells.The concentration kg/meal diet tilapias resulted improved hepatocytes intracellular glycogen levels lowest mean rate an increase cells cells, control.
