Effect of asphyxiation on the haemoglobin and glycogen content in an african catfish clarias gariepinus

الملخص EN

African catfish Clarias gariepinus was exposed to different time of hypoxia.

Some of the remarkable changes were observed in stressed fish in comparison to the control one.

It was noted that sudden asphyxia produces usual stress reaction, swimming speed is affected below a certain concentration of ambient o'xygen.

However, significantly decreased haemoglobin and glycogen content were found in the subsequent of hypoxia.
