The influence of acute handling stress on some blood parameters in cultured sea bream (Sparus aurata Linnaeus, 1758)
AbstractThe effect of acute handling stress on haematological profile, blood glucose and lactate (secondary stress markers) in cultured sea bream Sparus aurata was evaluated. Sixty six Sparus aurata were used and equally divided into two groups (A and B). Group A was not subjected to stress, Group B was subjected to acute handling stress. From each fish, biometric data and blood samples were collected to evaluate haematological profile, blood glucose and lactate. Unpaired t-test Student was applied to evaluate possible differences in parameters between the two groups. Red blood cells, haematocrit, haemoglobin, white blood cells (WBC), glucose and lactate showed an increase (P<0.05) in Group B compared with Group A, while mean corpuscular volume decreased (P<0.05) in Group B. The results highlight the role of studied parameters in monitoring the stressful conditions of aquaculture production which affect animal welfare and fish products quality.
