Abstract

The aim of this study was to evaluate the effects of a promising new immune stimulant in aquaculture (IMUNO-2865®) on biochemical parameters in sea bream during the winter stress period. A total of 640 sea bream were fed throughout 90 days with diets containing 0 (Group 1), 1 (Group 2), 10 (Group 3) and 25g (Group 4) of IMUNO-2865® kg-1 of feed. Samples were taken each month and 90 days after supplementation. No statistical differences among treatment groups were noticed for the following biochemical parameters: GLU, TRIG, AST, CHOL, LDH, URE and CREA. At the final sampling, total NH3 was higher in groups 3 and 4 compared to the control and the low supplementation group (P<0.05), while TP was significantly higher in group 4 compared to all other groups, and in groups 2 and 3 compared to the control group (P<0.05). Blood Ca++ levels were significantly higher after 60 days of feeding in all treatment groups compared to the control, and remained elevated in group 4 even after 90 days following secession of supplementation (P<0.05). The results of this study described the increase of biochemical parameters in the blood of sea bream after use of IMUNO-2865® but future research is needed to evaluate its potentially immunostimulative effect on fish in commercial aquaculture.
