Al-Abood A.Y., 1992. Studies on the relationship between some haematological parameters and the biology of the fish, Silurus triostegus. Acta Ichthyol. Piscat. 22 (2):197-201.
Studies made on the fish, Silurus triostegus showed that haemoglobin concentration and haematocrit value increased as the age of the fish increased up to the fourth year of age and then decrease afterward. The condition factor shows a high value during the beginning of the maturation period and drops down at the end of this period. The relationship between haemoglobin concentration and haematocrit value was investigated and the correlation coefficient (r = 0.9278) was calculated which is statically highly significant. The cause of those variations were discussed.
