“…These mixed results make their interpretation difficult; in addition, results of bivariate correlations between kidney histopathologies and the primary drivers of site discrimination for liver organic contaminants (HCB, BDE-47, and BDE-154) did not yield significant associations. Exposure to toxicants, particularly organochlorine pesticides, has been associated with the appearance of tubular degeneration and other kidney pathologies (Ayas et al, 2007). For instance, Costa et al (2010) reported renal and gill lesions in flatfish (Solea senegalensis) after exposure to sediments containing organic xenobiotics, attributing the damage mainly to PCBs and PAHs.…”

The health of Largescale Sucker (Catostomus macrocheilus) in the lower Columbia River (USA) was evaluated using morphometric and histopathological approaches, and its association with organic contaminants accumulated in liver was evaluated in males. Fish were sampled from three sites along a contaminant gradient. In 2009, body length and mass, condition factor, gonadosomatic index, and hematocrit were measured in males and females; liver and gonad tissue were collected from males for histological analyses; and organ composites were analyzed for contaminant content in males. In 2010, additional data were collected for males and females, including external fish condition assessment, histopathologies of spleen, kidney and gill and, for males, liver contaminant content. Multivariate analysis of variance indicated that biological traits in males, but not females, differed among sites in 2009 and 2010. Discriminant function analysis indicated that site-related differences among male populations were relatively small in 2009, but in 2010, when more variables were analyzed, males differed among sites in regards to kidney, spleen, and liver histopathologies and gill parasites. Kidney tubular hyperplasia, liver and spleen macrophage aggregations, and gill parasites were generally more severe in the downstream sites compared to the reference location. The contaminant content of male livers was also generally higher downstream, and the legacy pesticide hexachlorobenzene and flame retardants BDE-47 and BDE-154 were the primary drivers for site discrimination. However, bivariate correlations between biological variables and liver contaminants retained in the discriminant models failed to reveal associations between the two variable sets. In conclusion, whereas certain non-reproductive biological traits and liver contaminant contents of male Largescale Sucker differed according to an upstream-downstream gradient in the lower Columbia River, results from this study did not reveal the specific environmental factors responsible for the differences in health status among fish populations.Published by Elsevier B.V.

“…Mystus tengara, commonly known tengra is a freshwater catfish species of family Bagridae under the order Siluriformes. It used to inhabit in both flowing and standing waters of rivers, ponds, inundated fields and derelict water bodies.Fish are often used as indicators of such biological impacts of pollutants as they respond to low concentrations of toxic substances (Ayas et al, 2007). Alteration in the histology of the tissue such as gill, liver, kidney or intestine that are directly related to the contaminants serve as important bio-monitoring tools or bio-markers to assess the toxicity (Thophona et al, 2003).…”

Cypermethrin, the synthetic pyrethroid commonly used as a pesticide, contaminates the aquatic ecosystem as a toxic pollutant from agricultural and domestic washouts. An experiment was conducted to carry out an empirical study to investigate the sub-lethal effects of LC 50 value of a pyrethroid pesticide, cypermethrin 10EC on histological changes of kidney in Tengra, Mystus tengara at wet laboratory of the Faculty of Fisheries, Bangladesh Agricultural University (BAU), Mymensingh. The LC 50 value of cypermethrin 10EC was calculated by probit analysis and LC 50 value for 96 hours was found 0.133 ppm. The experiment was conducted with four treatments, each with three replications. Treatment one (T1) was used as control (0 ppm) and three concentrations, such as 0.026 ppm (20% of 96 h LC 50 ), 0.052 ppm (40% of 96 h LC 50 ) and 0.104 ppm (80% of 96 h LC 50 ) were used as Treatment two (T2), Treatment three (T3) and Treatment four (T4), respectively. For histological study kidney of studied fish were collected from control and experimental group at 7, 14 and 28 days interval up to the end of experiment of 28 days. The physical reactions observed in the treated fish were erratic swimming, discolorations of the skin, loss of reflex, hyperactivities, motionless state and these effects increased with increasing concentration of the toxicants and duration of exposure. The changes observed in the kidney tissues were vacuolation, necrosis, ruptured kidney tubules, Cellular degeneration and karyolysis were recorded. Cypermethrin 10 EC has adverse effects on the organs of fish, so it should not be used indiscriminately in agriculture and aquaculture.

“…A lot of researches have been carried out to show the impact of pesticides on decline in fish population (Scholz et al, 2012). Fish are often used as indicators of such biological impacts of pollutants as they respond to low concentrations of toxic substance (Ayas et al, 2007). Aquatic organisms from the Kiti River and vegetable plants commonly consumed by the local people in the township of Djidja (Benin) were contaminated by metabolites of DDT (Pazou, 2014).…”
