The effect of different acclimation temperatures on physiological parameters of
Clarias gariepinus over a period of eight weeks was assessed. Thirty-two fishes
weighing approximately 400.0+5.0g were divided into four groups (A-D) of eight
fish each, based on the water temperature to which they were subjected: Group A
(29+1o
C) was the control while groups B (23+1o
C), C (35+1o
C) and D (41+1o
C)
were the test groups. Haematological and biochemical parameters were
considered after eight weeks. The result showed that there was no significant
difference (at p<0.05) in the values at 23+1o
C, 35+1o
C and 41+1o
C, except for
haematocrit (Ht), haemoglobin (Hb) and total plasma protein (TPP) values, which
were significantly different at 23±1o
C and 41±1o
C relative to the control (29±1o
C).
The implication of temperature fluctuation of aquatic ecosystem on flora and
fauna is discussed in the text.
