The synthetic pyrethroid, cypermethrin toxicity was studied in fresh water fish 'Heteropneustes fossilis and the tissues like gill and liver were chosen for Histopathological effects by light microscopy, for 4 days and 7 days under sublethal concentrations. No Histopathological effects were observed in control group and 4 days group. Hence 7 days group was selected for the present study. Significant changes in Hepatic cells of liver were observed like cloudy swelling of hepatocytes, vacuolour degeneration, and dilation of sinusoids, Hepatic lesions, and Karyo Lexis. In Gill, oedema, Epithelial lining, curling of lamellae were observed. This study demonstrates the potential of electron microscopy in particular SEM, as a tool for detecting cypermethrin induced damage to liver and surface of gill lamellae.

Dioctyl phthalate (DOP) commonly used as plasticizer enters into aquatic environment from the industries manufacturing plastic products, PVC resins, cosmetics and many other commercial products. Therefore, this study was designed to evaluate the acute toxicity effects of Dioctyl phthalate on fresh water fish Clarias batrachus. The 96 hour LC50 of Dioctyl phthalate in Clarias batrachus was estimated as 14.5ml/L. Histopathological changes in liver of Clarias batrachus were determined by exposing them to a fraction of LC50(1/5th) dose with every change of water for 30 days.The liver of Clarias batrachus was excised at every interval of 30 days and histological changes of liver were studied under light microscopy. Liver tissues showed abnormalities. Centrilobular vacuolation, necrosis, eccentric nuclei and enlarged nuclei, Centrilobular degeneration of hepatocytes were observed in liver tissue of fish.

The present study was conducted to evaluate the effects of zinc cyanide (Zn(CN)2) on the ATPase (Na+-K+-, Mg2+, Ca2+) activity of the freshwater fish Cirrhinus mrigala (Ham). Fish were exposed to two sublethal concentrations (0.114 and 0.068 mg/L) and the effects were studied in the liver, muscle and gill tissues at the end of 5, 10 and 15 days of exposure. Cyanide intoxication resulted in marked changes in ATPases, represented by a significant decrease in the activities. Maximum inhibition was observed at higher concentration. The order of inhibition in the activity was Na+-K+-> Ca2+ > Mg2+ ATPase. These results imply an immediate adaptive response to the stress, demonstrating alterations in ATPase activities in the tissues of cyanide-treated fish. The present study clearly proposes that ATPases can be used as biomarkers of exposure of aquatic organisms to cyanide intoxication.

Histopathological studies of gill, liver and intestine of the experimental fishes Heteropneustes fossilis (Bloch) were made after 24 hours exposure to 50% ethyl alcohol extracts of Madhuca indica (G. F. Gmel) plant parts. The principal changes in the gills included distorted and disintegrated gill arches, shrunken and oedamatous distensions in the primary lamellae, swollen, shortened and coalesced secondary lamellae, vacuolated and disrupted epithelial and pilaster cells and disorganized gill filaments. The changes in the liver included compactly or loosely arranged hepatic cells, dialated and swollen central vein, blood coagulated portal vein, reduced or swollen hepatic artery and dispersed sinusoids. In the intestine disintegrated serosa, swollen and partially ruptured muscularis, vacuolated submucosa, damaged mucosa, disintegrated and reduced lamina propria and distended and coalesced villi were observed. On the basis of affectivity the most affected organ was the gill followed by liver and intestine. Affectivity of the plant parts on the three organs was in the order seed > bark > leaf for gill, intestine and was seed > leaf > bark for liver.

Health status investigation of shing (Heteropneustes fossilis) was carried out through clinical and histopathological observations. During four months from January 2018 to April 2018. The data were collected from eight fish farms. Clinical signs of fish were physical deformity, reddish whitish lesions, abrasion and reduced mucus in the months of January and February from the investigated fish farms. Clinically fish were almost normal in the months of March and April. Histopathlogically observed pathological changes in gill were lamellar missing, splitted gill lamellae, hemorrhage, hypertrophy, vaccums and presence of parasites in January and February. In case of liver the examined fish had hemorrhage, vaccums, necrosis and fat bodies also in the months of January and February. Organs of the examined fishes were almost normal in the months of March and April. The purpose of the study was to determine the health status of farmed shing. The main objectives of the study were to observe clinical and histopathological changes in liver and gill of farmed shing (H. fossilis) at various fish farms of Mymensingh region and to determine the health status of the shing in the investigated months. From the present study, it was found that external organs like gill were more affected compared to internal organ like liver. From the present investigation, it was also observed that the fish were more affected in the months of January and February i.e. in winter season. Res. Agric., Livest.

The fresh water fish Puntius ticto were exposed to lethal concentration of water soluble fraction (WSF) of petrol (5%-PF1, 10%-PF2, 15%-PF3, 20%-PF4 and 25%-PF5) for 96 hours. The exposure of WSF produced some conspicuous histopathological changes in liver. The swelling of hepatocytes, degeneration, necrosis, hemolysis, dilation, congestion and fibrosis in blood sinusoids were the prominent changes observed. The histological analysis showed increasing damages dose-dependents and time-dependents.

The toxic effect of Monocrotophos on some biochemical parameters such as Protein and Amino acid in freshwater fish Oreochromis mossambicus were studied. The fishes exposed to 1/10th, 1/20th, and 1/30th sublethal concentration of Monocrotophos for 30 days. The tissue samples of gill, liver were analysed at the end of the 30th day exposure period. A decreased value of Protein and Amino acid were observed in 1/10th, 1/20th, and 1/30th sub lethal concentration of Monocrotophos at the exposure period of 30 days while comparing with the control group. The high variation observed in the 1/10th sublethal level of 30thday exposure. While compare with control group the effects of Monocrotophos on fish found during this experiment showed that the level of protein and amino acid level in various tissues (gill and liver) of Oreochromis mossambicus decreased.
