Effects of different stressors in haematological variables in cultured Oreochromis aureus S

Since haematological variables can be used to assess the health state in cultured fish, a haematological characterization of clinically healthy Oreochromis aureus was done to establish the reference indices of this species. Fish were subjected to different stressed conditions (bacterial infection, n...

Description
Summary:Since haematological variables can be used to assess the health state in cultured fish, a haematological characterization of clinically healthy Oreochromis aureus was done to establish the reference indices of this species. Fish were subjected to different stressed conditions (bacterial infection, nitrite intoxication, malachite green overdose) to study the changes in the haematological indices and its relation with the health condition. This species showed microcytic anaemia under experimental bacterial infection by Corynebacterium sp.; anaemia, neutrophilia and erythrocytes deformation following nitrite intoxication and medication overdose with malachite green.
