Mechanization of agriculture to promote and improve the yields from agricultural practices has necessitated the use of pesticides and other agrochemicals. The effects of using these pesticides on the environment are rarely considered by farmers. This study investigated the effects and sub-lethal effect of atrazine on tilapia, an ubiquitous culturable fish species. The 96 hr LC50 was determined using static renewal bioassay method while the effect on haematological parameters was determined after exposure for 3 weeks to sub-lethal doses of atrasine. The LC50 was found to be 6.977mg/l. Sub-lethal exposure resulted in anaemia and increased the white blood cell counts.
