Effects of Natural Pituitary and Synthetic (ovaprim) Hormones on Haematology of Clarias Gariepinus Injected at Various Hours of Inducement in Mubi

This study was carried out to determine the effects of natural and synthetic hormones on haematology of Clarias gariepinus broodstock. 12 broodstock of mean weight of 1.7kg and mean length of 26cm were used for the experiment. One male and one female served as control, one male and one female for natural hormone and one male and one female for synthetic hormone. The brooders were injected at the same time at 27oC water temperature. Blood samples were collected at 00hrs, 6hrs, 12hrs and 24hrs of injection from all the treatment and control. Blood samples were analysed at the end of the experiment. Statistical analysis was used to analyse the data collected on haematological parameters. At the end of the research it was discovered that there is significant variation in all the haematological parameters between the natural and synthetic hormone and between the male and female fish with the female fish having the highest value of almost all the haematological parameters during the course of the study. The use of natural hormone is therefore recommended in aquaculture.
