Changes in hepatosomatic index and histoarchitecture of liver in common carp exposed to organophosphate insecticide sumithion

Sumithion is widely used in larval rearing aquaculture ponds to control aquatic insects. This experiment was carried out to evaluate the effect of sumithion on hepatosomatic index and liver morphology in common carp, Cyprinus carpio. Acute toxicity of sumithion (96 h LC50 value) was first determined and it was 8.05 ppm for common carp. The fish were exposed to two sub-lethal concentrations (0.85 and 1.7ppm) of sumithion for a period of 21 days. A control set was also run for the same time with the same number of fish without sumithion (0 ppm). There was a marked increase in the hepatosomatic index in both concentrations (0.85 and 1.70 ppm) compared to control (0 ppm). Several histological changes of liver, such as necrosis, patchy degeneration, degenerated hepatocytes, vaculation and blood spilling were observed after exposure to sumithion with dose and exposure time dependent manner. The present investigation revealed the toxic potentiality of sumithion on common carp which alters liver morphology that may lead metabolic changes in fish.Asian J. Med. Biol. Res.

Carp Cyprinus Carpio

The activity of acetylcholinesterase (AChE) in the vital organs of fish such as gill, liver, muscle, kidney and brain of the freshwater common carp Cyprinus carpio (C. carpio) was investigated after exposing to acute lethal toxicity (ALT) and chronic sublethal toxicity (CST) of phorate. C. carpio fish were exposed to ALT (LC50/96 hours - 0.71 ppm/l) of Phorate for one day and 4 days and CST (one-tenth of the LC50/96 hours - 0.071 ppm/l) of Phorate for 1, 7, 15 and 30 days and the concentration related differences in the inhibition and recovery of the AChE enzyme activity was evaluated in the target organs of the fish. Relative to controls, the activity of AChE in all the organs of the fish exposed to ATP gradually decreased significantly ((P<0.05)) at 1 and 4 days of exposure period whereas in the fish exposed to CTP the AChE activity was elevated at day 1 and gradually decreased from day 7 to day 15 followed by an increase at day 30 in all the organs significantly (P<0.05). Based on the percent values obtained the inhibition of AChE activity was predominantly more in the organs of the fish exposed to ATP in a concentration-dependent manner. On prolonged exposure for 30 days in CTP the AChE activity was restored gradually depending on the initial pesticide exposure concentration. Findings from this study have demonstrated that inhibition of AChE activity in C. carpio is a useful biomarker for assessment of anticholinesterase pesticide contaminations in water.

This study was conducted in the laboratories of the College of Agriculture, University of Basrah for 75 days, in order to study the effect of using prebiotic (Safmannan) and bio-antibiotic (Fluconazole) on some growth and haemato-immunological parameters of the common carp Cyprinus carpio L. The fishes were divided into four categories of treatments; the first treatment was the control (basal diet), the second and third treatments (T2 and T3) contained 500 and 1000 mg.kg-1 diet of Safmannan, respectively while the fourth treatment consisted of adding 150 mg.100 g-1 diet of bio-antibiotic Fluconazole. The second and third treatments were significantly higher (P<0.05) than control and antibiotic treatments in the growth parameters such as the average of daily weight gain, the average of specific growth and the feed conversion of the second and third treatments. Blood proteins (albumin, globulin and total protein) showed significantly higher (p <0.05) values in the second and third treatments than control and antibiotic treatments. No significant differences were noted in both packed cells volume (PCV) and haemoglobin (Hb) among different treatments. The value of alanine aminotransferase (ALT) showed no significant differences among all treatments, while alkaline phosphatase (ALP) was significantly higher and aspartate transaminase (AST) was significantly lower in the fourth treatment. Hepatosomatic index (HSI) was significantly higher in all treatments compared with the control, while no significant differences in spleen somatic index (SSI) were noted among all treatments. Differential white blood count exhibited no significant differences among the treatments for eosinophils, basophils, lymphocytes and monocytes, while neutrophil count was significantly decreased in all treatments in comparison with the control.
