“…Furthermore, the decrease in glycogen inclusions in aphantoxin-exposed fish hepatocytes may be attributed to the increased mobilization of energy stores associated with toxic stress (Dezfuli et al, 2006;Abdel-Moneim, 2014). Our results, together with those of previous studies, suggest that aphantoxins may cause histological and ultrastructural alterations and cell death in zebrafish liver through both apoptotic and necrotic pathways, which may represent important aphantoxin toxicity indicators (Abdel-Moneim et al, 2012).…”

“…These are especially significant in the liver, because of its important detoxification function (Apte and Krishnamurthy, 2011;Abdel-Moneim et al, 2012). In the current study, aphantoxins led to histological and ultrastructural alterations including hyperemia, cell and organelle edema, widened intercellular spaces, shrinkage or deformation of the cell and nucleus, cellular vacuolization, glycogen reduction and lipid accumulation.…”

“…Acute toxicity studies of cadmium on the edible carp, Catla catla conducted by Sobha et al [28] revealed significant changes in the biochemical constituents of the fish like glucose, glycogen, total proteins, lipids and free amino acids. Reports by Abdel-Moneim et al [29] on gills and liver of Oreochromis niloticus from polluted wetland environments, Saudi Arabia showed that bioaccumulation of Cd were mostly above the WHO reference values. These results are in agreement with the present study.…”

In the present study, the two lakes, Vengaiah lake (Lake A-Sewage polluted receiving discharge from storm water drain) and Yellamallappa Chetty lake (Lake B-Industrially polluted) situated near Krishnarajpuram-Hoskote taluk, Bangalore, Karnataka were selected for analysis of trace metals viz., arsenic, aluminium, cadmium, lead, mercury, iron, copper and zinc in water samples. Muscle and gill tissues of freshwater fish Labeo rohita reared in these water bodies were analysed for bioaccumulation of trace metals. Hebbal fish farm was considered as a reference site (Control site) for water and fish samples. Trace metals were analysed by atomic absorption spectroscopy and values were compared with those recommended by FAO/WHO in water and fish samples. Trace metals such as Al, As and Hg were detected in the water sampled from lake B which is attributed to the differences in the sources of pollutants. Fish tissues viz., muscle and gills sampled from Lake B exhibited high concentration of Al, Pb and Cd content showing a positive correlation with their concentration in water samples. The remaining metals as Cu, Zn and Fe were detected in water sampled from all water bodies and also in the fish tissues. Gills exhibited higher concentration of metals in fish from lake B. Bioaccumulation of these trace metals in fish tissues may cause potential danger to human health when consumed on regular basis. Thus necessary remedial measures are required to combat water contamination and its management keeping in view the aquatic ecosystem and public health. Values were statistically significant at P < 0.0001.

“…On the other hand, infected animals (T3 and T4) showed an increase in these characters, evidencing the high cellular synthetic activity, probably associated with production of inflammatory cytokine or detoxification enzymes, as well the increase in volume of mitochondria and lysosomes (Strmac and Braunbeck 2002, Marchand et al 2006, Abdel--Moneim et al 2012, Dabrowska et al 2012, Gutiérrez-Praena et al 2012.…”

Ascophyllum nodosum in the diet of tilapia (Oreochromis niloticus) and its effect after inoculation of Aeromonas hydrophila

ABSTRACT.-Oliveira S.T.L., Veneroni-Gouveia G., Santos A.C., Sousa S.M.N., Veiga M.L., Krewer C.C. & Costa M.M. 2014. Ascophyllum nodosum in the diet of tilapia (Oreochromis niloticus) and its effect after inoculation of Aeromonas hydrophila. Pesquisa Veterinária Brasileira 34 (5) The objective of this study was to evaluate the effect of Ascophyllum nodosum brown seaweed meal (FAM) on the health of Nile tilapia submitted to inoculation with Aeromonas hydrophila. The experiment was conducted for a period of 40 days using 120 Nile tilapia fingerlings, with age of 40 days, distributed in 20 tanks. A diet including Ascophyllum nodosum seaweed meal at 20g.kg -1 and a control diet (without FAM) were provided which constituted the treatments. Thirty days after beginning the experiment, A. hydrophila was inoculated by bacterial inoculum diluted in sterile saline solution at a concentration of 10 6 CFU ml -1 . Except for the width, which was greater for the treatment with the provision of FAM (P<0.05), there was no influence on the performance parameters of the fingerlings, but the occurrence of lesions in animals inoculated with A. hydrophila and fed with FAM was lower and they also exhibited a decline in the lesions in a shorter period of time than the control group. FAM prevents hepatopancreatic congestion in infected animals. Ascophyllum nodosum brown seaweed meal reduced the number of lesions in fish in a shorter time when compared to the control group.
