The cause of the histological damage of Faunus ater (gastropod mollusk) gonad has been identified in the samples from two rivers, namely Bale River and Reuleng River which flow through residential, agricultural and industrial areas. The heavy metal concentration within the tissue of Faunus ater was analyzed with Atomic Absorption Spectrophotometer (Shimadzu AA 630). Meanwhile, the histological damage on gonads was observed microscopically. Afterwards, the damage levels obtained from the two respective rivers were compared and analyzed with t-test. The results confirm the histological damage that occurred in the gonads of Faunus ater collected from the two rivers. The gonadal damage of female Faunus ater from both rivers was found not to be significantly different, observed by the number of developed and damaged oocytes. It was also found that the gonads of male Faunus ater collected from Bale Riverl, have higher quantity of spermatogenic cells, in which they experience greater necrosis than the ones from Reuleng River.

The present work aimed to study some aspect of the reproductive biology of the P. javanicus with emphasis on histopathology abnormalities of gonads and intersex problems. Fish samples of Puntius javanicus (local name:tawes) were collected from Mas River on the Surabaya downtown whereas highly pollution. Fishes were identified for morphological abnormality and gonad organs were evaluated. Histological preparation was done to observe the gonad condition. This report reveals that 20% male P. javanicus were found to be feminized on July 19, 2012 collection from that river. Some histological samples indicated the presence of testis-ova in fish gonad, which indicated the occurrence of intersex of this species. The above finding suggests that greater attention needs to be given to xenobiotic pollutants and endocrine disrupting chemicals problems.

Aras River and its reservoir play an important role in fisheries and water supplies in the northwest of Iran. It is considered that the river water is polluted by various anthropogenic activities. This study was performed to determine the histopathologic effects of water pollution on a fish species, Leuciscus aspius inhabiting the river. In July 2015, the fish were caught in two different stations of Aras River in Poldasht, Iran. The histopathological abnormalities were detected microscopically and evaluated with quantitative analyses in three organs of the fish. Hypertrophy, filament dilatation, lamellar epithelial liftings, thickening of filament, especially curve, a decrease of the mean length, necrosis, fusion, and lifting in lamellae were observed in gills. Main histopathological abnormalities in the liver were non-homogenous parenchyma, the proliferation of hepatopancreas, congestion, and degeneration of central vein, increasing melanomacrophage aggregates, and sinusoidal dilations. The observed changes in kidney included the degenerations of renal tubules, increasing melanomacrophage aggregates, pyknotic nuclei and vacuolization in proximal and distal tubule epithelial cells, and lymphocyte infiltration in renal parenchyma. It was found that the frequencies of the histological lesions were higher in the liver in comparison with other organs. It was concluded that the increased histopathological alteration in the fish tissues may be related to the presence and elevated toxic contaminants in the river.

In the present study, the histological structures of the liver, intestine, stomach and ovary of Lates niloticus from Lake Nasser (Kalabsha station) were studied during spring season, 2013. Several histopathological changes were observed in liver, intestine, stomach and ovary of the studied fish. In the liver, vacuolar degeneration, focal areas of necrosis, destruction of hepatoportal blood vessels and haemorrhage between the hepatocytes were observed. Besides, intravascular haemolysis and dilation and congestion were noticed in sinusoids. The histological changes in stomach and intestine included fused villi, the outer membrane of villi were broken, hemorrhage in the sub mucosa region and cells swelling. In the ovary, degenerative and atretic oocytes, proliferative changes in the granulosa of the oocytes, haemorrhage between the oocytes and intravascular haemolysis in some ovarian blood vessels were seen.

Background: Pollution of the aquatic environment by inorganic and organic chemicals is a major factor posing serious threat to the survival of aquatic organisms including fish. Lake Manzala (LM) is one of the Egypt's northern Delta Lakes situated on the Mediterranean Coast of the Delta. It is affected by drainage water polluted by different heavy metals that their concentrations exceed the maximum world permissible levels. Aim: This study aims to study the testicular histopathological alterations of Oreochromis niloticus using light microscope and the mature sperm using TEM during spawning season in LM. Materials and methods: Samples of water and 48 specimen of Nile tilapia, Oreochromis niloticus about 14-20 cm in length were collected from two areas; Demitta branch of river (RN) at Mansoura city as a control site and LM as a polluted area during the spawning season from March-June. The gonado-somatic index (GSI) was then calculated for each fish samples. Pieces of testes were then taken and prepared for light and electron microscopic studies. Cd and Pb were estimated in water samples during the spawning season from March to June. Results: Examined Sections revealed that the testes of specimens of LM had degenerative germinal epithelium of the seminiferous tubules, vacuolization in proliferating germ cells; decline in spermatogenic cell and sperm density than those collected from RN. Ultrastructure study of mature sperm of LM revealed nuclear degeneration, vacuolization and shortage of bilateral fins of the flagellum comparing to mature sperm of RN. Conclusion: This study giving an alarm that environmental hazard like increasing the levels of different heavy metals as Cd and Pb could alter the sperms structure and their ability to produce new offspring, and further studies may be needed to confirm these findings.

High population growth have led to a tremendous intensification of rice production, which in turn has significantly increased the amount of pesticides applied in rice cropping systems. Since pesticides are toxic by design, there is a natural concern on the impact of their presence in the environment on human health and environmental quality. The present study was conducted to assess the nature and extent of pesticide induced pathogenesis in the tissues of gills, liver and kidney of Etroplus maculatus inhabiting the paddy fields of Kuttanad, Kerala, India, which is subjected to long term exposure to sublethal concentrations of a common pesticide, phosphamidon, used in these area. The organ index calculated based on various reaction patterns of the different organs. The study showed that the gills are severely affected, liver is moderately affected and the kidney is the mildly affected organ. As an indicator of pollution, histology represents a useful tool to assess the degree of poll...

The histological structure of gills, liver (hepatopancreas), spleen, intestine and some biochemical aspects of muscle of the seabream (Sparus aurata) and seabass (Dicentrarchus labrax) inhabiting the Bardawil Lagoon were studied. Also, some physico-chemical parameters of water, heavy metals concentrations and pesticides residues in fish muscles were measured. Several histological alterations were observed in the gills, including proliferative, degenerative, necrotic changes and edema in the epithelium of gill lamellae, mucous and chloride cells proliferation. Besides dilated and congested blood vessels of gill filaments were observed. The spleen showed tissue with necrotic area, blood vessels with esinophilic fibrous material and early granulomas are presented surrounding damaged blood vessels. In the liver, vacuolar degeneration of hepatocytes with focal areas of necrosis and fibrosis, aggregations of inflammatory cells between the hepatocytes, dilation and congestion in blood sinusoids. The intestine showed dilation in blood vessels with congestion and atrophy in the muscularis with degenerative, necrotic changes and edema in submucosa. These histological alterations are widely used as biomarkers to evaluate the health of the two fish species. Also high levels of muscle transferase enzymes [Alanine aminotransferase (ALT) and aspartate aminotransferase (AST)] were recorded.
