The study analyzed the seasonal variation in physicochemical parameters on fisheries of Ebonyi river system. The objectives of the study were to analyze the physiochemical properties of Ebonyi river system and its correlation and to make necessary recommendations for the general improvement of fish management in the study area. Multimesh gillnets were used to monitor the abundance and structure of the fish fauna. Stratified random sampling was carried out in each water body. The fishes were caught, identified, counted, graded, measured and weighed according to species. The species for chemical and histological analysis were taken immediately after weighing to the laboratory. Concentration of metals were studied in fish blood, liver and in the tissue lying between the lateral lines and the fins, since high concentrations of metals do not imply that the metal have a toxic effect (-). Toxicity of metals is mostly associated with vital physiological functions, such as enzyme activity, modifications in membrane, lipid composition and changes in tissue structures. It was observed that in dry season, water temperature of Mkpuma river and pond water were statistically similar (p > 0.05). However, their values differed significantly of those of Ameka Dam, Enyigba River and Ebonyi river. The pH in dry season across study areas was similar for Ameka Dam and Enyigba River and these were significantly higher (p < 0.05) than those of other study areas, which did not differ significantly (p > 0.05) among themselves. Mkpume river, Ebonyi river and Ameka Dam had statistically similar DO values (p > 0.05) while Enyigba and pond water had insignificantly different DO concentration (p > 0.05). The CO 2 concentration in dry season was significantly higher in Mkpume river followed by Ameka dam but the CO 2 of Ameka dam was not significantly different (p > 0.05) from those of Ebonyi river and pond water. Enyigba River had the least CO 2 concentration. Water had it highest transparency in Enyigba river (p < 0.05) followed by those of Mkpume river, pond water, Ebonyi River and Ameka dam. It was also observed that during rainy season, water temperature in Mkpume river was significantly different (p < 0.05) from those of other study areas while the water temperature of Ameka Dam was the least. Mkpume river also had the highest pH value but it does not differ significantly (p > 0.05) from that of Ebonyi river. However, the pH of pond water was significantly low (p<0.05). There was no significant difference in the DO concentration of all study area during the rainy season. Based on the research findings, the following policy recommendations are therefore proffered. World health /bank should please assist the state Government in making available good quality refined urban tap water to the villages and subborbs so as to save the lives of both Urban and Rural dwellers. Safe disposal of domestic wastes and control of industrial effluents should be practical and where possible recycled to avoid these metals and other contaminants from go...

I n the present work experiments were carried out to investigate the hazardous effects of the organophosphorous insecticide (Hostathion) on the histology, histochemistry and physiology of the liver of the catfish (Clarias gariepinus) after exposure to LC50, VzLCso and ViLCso of the insecticide for different periods. The results showed that the histopathological changes induced in the liver were mainly represented by liver cord disarray, cytoplasmic vacuolization of the hepatocytes, damage of blood sinusoids, blood vessel congestion and inflammatory leucocytic infiltration. The histochemical observation revealed marked reduction in glycogen contents and total protein contents of the liver cells as compared with the control materiaL Physiologically, different treatments at different time intervals resulted in variable degrees of inhibition in 5'-nucleotidase and alkaline phosphatase activities. These changes were both concentration-and time-dependent.

“…Tissue sample of the liver from fishes treated with 0.004, 0.032, and 0.064 ppm of diazinon showed marked degenerative changes, severe necrosis, pyknosis, haemorrhage and vacuolation in all the tested fish which is in agreement with the findings of for Anabas testudineus, Channa punctatus, and Barbodes gonionotus; and Omitoyin et al (1999) for Sarotherrodon galilaeus. Dubala and Shah (1979) exposed Channa punctatus to 1.0 ppm malathion and reported either damage or disintegration in about one third of hepatic cells and acute shrinkage of nuclear materials. Kabir and Begum (1978) reported cytoplasmic degeneration, pyknotic nuclei in liver tissues; vacuolation in hepatic cells and rupture of blood vessels; degenerative hepatic cells and necrotic nuclei in Heteropneustes fossilis exposed for 25 days to 5, 10, and 20 ppm diazinon, respectively.…”

et al. 2017

The organophosphorus insecticide, diazinon that is widely used in agricultural field and private industrial premises to control pests, easily accumulates in aquatic ecosystems and exerts toxic effects on aquatic animals. The study aimed to evaluate the acute toxicity (LC50) of diazinon on Glossogobius giuris and histopathological alterations of its gonads, liver and kidney due to the effect of this insecticide. G. giuris were exposed to different concentrations of diazinon ranging from 0.00025 ppm to 2.048 ppm with parallel untreated control. At the doses of 0.0005 ppm, 0.001 ppm, 0.002 ppm, and 0.004 ppm 40%, 50%, 70%, and 90% mortality of G. giuris were observed within 96 hrs, respectively, whereas, 100% mortality was observed at doses above 0.008 ppm. Based on probit analysis, the LC50 value of diazinon for 96 hrs of exposure on G. giuris was found as 0.001 ppm. During the exposure trial several behavioral alterations including restlessness, sudden and quick movements, loss of equilibrium, increased opercular activities and paralysis were observed in the fish. The histopathological changes observed in the tissues of G. giuris indicate that sub lethal concentration as well as higher concentration caused moderate to severe alterations in the liver, kidney as well as gonads. Kidney was found to be the most seriously affected organ compared to gonads and liver. Major histopathological changes like fragmentation of testis and ovary with ruptured wall, karyolysis, hypertrophy, pyknosis and degenerative changes such as necrosis of tubular and haematopoietic cells of kidney, necrotic hepatocytes, pyknosis, hypertrophy, haemorrhage and vacuolation were observed in the liver cells. The present study demonstrated that diazinon is highly toxic especially to G. giuris and thus, indiscriminate use of this insecticide in the agriculture and industrial sectors should be strictly controlled.Progressive Agriculture 27 (4): 530-538, 2016
