“…Reduction in the values of these parameters was also reported in Prochilodus lineatus exposed to clomazone [48], and in Labeo rohita exposed to fenvalerate [49]. Reduction in the erythrocyte count was reported in Cirrhinus mrigala exposed to ibuprofen [50], and Clarias albopunctatus exposed to acetellic [51]. Our observations are also consistent with the trend in Heteropneustes fossilis, exposed to adrin and fenvalerate [52], and in Salmo gardneri and Mystus vittatus exposed to pesticides [53].…”

“…This is probably due to rupture of blood vessels of the gills and possible reduction in the haemotological parameters of erythrocyte count, haematocrit and mean corpuscular volume of the fish. Mgbenka et al (2005) reported similar toxic effects with clogging of the gills with mucus of C. gariepinus due to lindane exposure. These observations are also in agreement with earlier reports by Okoli-Anunobi et al (2002) on the lethal effect of the detergent (Elephant blue) on the Nile tilapia.…”

Diethyl Phthalate (DEP) is used as a plasticizer, a detergent base, in aerosol sprays, as a perfume binder and after shave lotion. It is known to be a contaminant of fresh water and marine ecosystem. Therefore, a study was designed to determine the acute toxicity effects of DEP on a fresh water fish, Clarias gariepinus fingerlings. The fish was treated with 50, 75, 100 and 150 µg/l. DEP was dissolved in distilled water to determine the LC 50. There was 100% mortality observed in 150 µg/l. The LC 50 of DEP was estimated at log toxicant concentration as 2.217, 2.734, 3.435 and 3.931 µg/l at 24, 48, 72, 96 h and 1.871µg/l for the total death. This shows that the impacts are dose and time dependent with respect to marked reduction in mortality rate. At sub-lethal concentrations of the test substance at 30, 40, 60 and 80 µg/l in a renewal bioassay system, the water and the test compound were changed intermittently. One group was maintained as a control in dechlorinated water. There was significant difference (P < 0.05) in brain and muscle AchE activity compared to the control. The liver ACP activity was statistically significant (P < 0.05) at day 15 while the muscle ACP in other treatment groups showed no significant difference (P > 0.05). Liver AST showed no significance in all treated groups (P > 0.05) and liver ALT activity was statistically significant (P < 0.05) at day 30 only. The haematological parameters (HB, PCV, RBC and WBC) carried out showed that haemoglobin and erythrocyte levels estimated in all treatment groups to the duration of exposure showed no significant difference (P > 0.05) compared to the control. The park cell volume showed a significant difference (P < 0.05) at day 30 only. The leucocyte count throughout the exposure period showed that the mean values are statistically significant (P < 0.05) at day 15 only compared to the control. The mean cell volume (MCV) showed a significant difference at day 15 (P < 0.05) whereas mean cell haemoglobin (MCH) and mean cell haemoglobin concentration (MCHC) showed no significant difference (P > 0.05) throughout the exposure period. No significant difference was seen between the lymphocytes and the neutrophils. In day 0 and 15 only, the monocytes and the lymphocytes showed a significant difference (P < 0.05). The gill damages indicated toxicity of DEP with raised lamella, oedema of the lamella epithelia, loss of lamellar epithelium, mild oedema and raising of the filament. The liver damage showed focal necrosis and vacuolization, hepatocyte degeneration in the liver. These alterations may have long term effects on that that are continuously exposed to DEP in the aquatic environment.

“…Similarly, rogor, sumithion and monocrotophos (OPs) exposure to C. batrachus, A. cuchia and A. testudenius resulted in leucocytosis (Goel and Maya 1986;Kalair et al 1993;Santhakumar et al 1999;Mgbenka et al 2005). Thakur and Sahai (1987a) and Kumar et al (1999) noted marked increase in TLC in G. gotyla and H. fossilis poisoned by carbaryl and deltamethrin, respectively.…”

Haematological parameters, such as erythrocyte and leucocyte count, erythrocyte indices and thrombocyte number vis-a-vis coagulation of blood has been considered bioindicators of toxicosis in fish following exposure to organochlorine, organophosphate, carbamate and pyrethroid insecticides. This review deals with the effects of insecticides on the morphology of red blood cells, total erythrocyte count, haemoglobin content, haematocrit, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, erythrocyte sedimentation rate, total and differential leucocyte counts, thrombocyte count and clotting time in the peripheral blood of a number of teleosts. The review also takes stock of knowledge of the subject and explores prospects of additional research in the related area.
