This study was aimed at detecting differences among tilapia species in immunological and biochemical parameters that are indicators for fish health. In addition, six blood parameters that are indicators of stress were measured, glucose concentration, ceruloplasmin activity, lysozyme activity, respiratory burst activity, haematocrit and leucocrit, and their levels were compared among groups. A calibration experiment was conducted with commercial stock of tilapia to optimize a protocol for measuring stress response in tilapia. An air exposure stress was induced to six groups of fish and blood samples were taken at six different times: 15 min, 1, 2.5, 4.5, 6 and 24 h, after inducing stress. The highest responses to stress were observed after 2.5–4.5 h. A second experiment was conducted with four tilapia species: Oreochromis aureus (Steindachner), O. mossambicus (Peters), a red strain and the wild type of O. niloticus L. Levels of serum biochemical components and parameters of the innate immunity response to stress were compared in ten fish from each species. Significant differences were observed. Oreochromis aureus differed from the other three species (notably from O. mossambicus) in most of the measured immune response traits (glucose concentration, lysozyme activity, haematocrit and levels of total protein and IgM after stress) and serum biochemical components (protein, albumin, triglyceride, cholesterol, calcium, magnesium, phosphorus, bilirubin and β-hydroxybotiric acid). The identified differences suggest that hybrid families from O. aureus and O. mossambicus may be used to construct a segregating population for genetic analysis of the innate immune response to stress. Thus, these two species were bred for segregating F2 population, suitable for quantitative trait loci studies for the innate immune response to stress.
