Dietary LR supplementation significantly enhanced Haematocrit
of red sea bream as a general health response towards nutritional
strategies. In the present experiment, Haematocrit content was
significantly highest in fish fed LR3 diet. Other LR supplemented
groups showed intermediate values whereas control group showed
the lowest value. This indicated that dietary LR elevated the health
status of fish. Similarly, Dawood et al. [37,40] and Panigrahi et al.
[23] reported the enhanced Haematocrit level by the supplementation
of probiotics in red sea bream and rainbow trout diets,
respectively.
