Influence of water quality on some haematological parameters during breeding phase in the freshwater fish, Notopterus notopterus
Author(s): RS Kulkarni
Abstract: The influence of water quality on blood haematological parameters was investigated during breeding period (spawning) in the fresh water fish,
Notopterus notopterus. This fish is available in large numbers in all the three aquatic bodies, two rivers (Bheema and Kagina rivers) and one small streem (Saradagi Nala). Temperature, oxygen and pH are important environmental factors considered for the present study and these are found to ensure the fish to survive, its distribution and normal reproductive functioning of the fish in an aquatic body. The reproductive activity was assessed based on gradual changes in the gonadosamatic index (GSI) which increases on approaching breeding period during June- July and spawning occurs in August by the onset of rains. The change in the blood parameters such as haematocrite (Hct), haemoglobin (Hb) concentration and RBC count was observed. The relationship between haemoglobin and oxygen differs between loading and unloading sites. The haematological parameters such as RBC count, haematocrite (Hct) and haemoglobin were compared and found to be differed with reference to water dissolved oxygen, hydrogen ion concentration and temperature, there is lower RBC count, subsequently lower haemoglobin and haematocrite in the fish collected from Kagina river than the fish from other two aquatic bodies, this may be due to difference in the O
2 or CO
2 transport as a result of increased metabolic activity. The less number of erythrocyte count are likely due in part to an increase in oxygen consumption and metabolic rates corresponding to the rise in water temperature. High level of dissolved oxygen, moderate hydrogen ion concentration and temperature of water creates a suitable ground for its normal reproductive physiology of the fish.
