Abstract
Throughout this investigation the effects of three commonly used agricultural pesticides, endosulfan (an organochlorine), malathion (an organophosphorous) and carbaryl (a carbamate) were studied on circulating levels of T4, T3, and the T3/T4 ratio of the fresh water catfish
Female
Results obtained showed that after 96 hours of exposure to endosulfan there was a significant increase in T4 in both vitellogenic and post-vitellogenic phases, when compared to the control, where as carbaryl significantly decreased T4 levels (Fig. 1). Malathion showed no difference in T4 levels in both phases when compared to the control (Fig. 1). Upon investigating levels of T3 in both vitellogenic, and post vitellogenic phases, results showed that both endosulfan and malathion decreased levels of T3 as well as T3/T4 ratio also (Fig. 1 and
