Combined effects of marine silages enriched with Lactobacillus sakei 5-4 were evaluated on growth performance, immune activity and disease resistance of Pacific red snapper (Lutjanus peru) against Aeromonas veronii infection. The experimental fish were divided into three groups which were fed with each one of the following diets: silage-probiotic-free diet (control, C group), Pacific creole-fish silage diet supplemented with live L. sakei (10(6) CFU g(-1)) (FSLact group) and Humboldt squid silage diet supplemented with live L. sakei (10(6) CFU g(-1)) (SSLact group) for 6 weeks. After 6 weeks, fish were immunocompromised with pathogenic A. veronii and spleen and liver samples were processed for histopathological studies. Generally, the results showed enhanced growth performance in fish fed the diet containing SSLact at 6 and 7 weeks compared with fish fed control diet. Addition of SSLact had an increase in plasmatic protein at week 6 and post-challenge. Hemoglobin concentration increased after challenge in fish fed with SSLact compared to control group. At week 6 and post-challenge the results indicated that, the fish groups which received diet supplemented with SSLact revealed significant increase in humoral immune parameters. Histologically, fish fed C diets showed marked fatty degeneration and great activation of melanomacrophage centers compare with SSLact and FSLact groups. These results support the idea that the marine silages with squid as protein source enriched or combined with L. sakei 5-4 increases the body weight and stimulates the physiological and humoral immune parameters in Pacific red snapper infected with A. veronii.
