“…According to Mallatt (1985), these changes may reflect a physiological adaptation to stress. Nevertheless, despite protecting the gill areas to ensure the maintenance of the osmoregulatory functions, these can lead to dysfunction or nonfunctioning of the gills and cause asphyxia (Tamse et al 1995). The lesions in the gills of the exposed organisms in the samples of January 2004 sediment were more severe, confirming the results of the bioassays of partial chronic toxicity.…”

“…This is in addition to the engagement of aerial mode of respiration so as to disengage gill respiration and by implication, prevent continuous gill contact with the toxicant. The respiratory distress might be due to gill epithelia damage or excessive mucous coating of gill epithelia surfaces (Tamse et al, 1995;Abalaka et al, 2010). The nervous compromise was initially characterized by hyperactivity and later, by increasing states of motionlessness, adoption of different postures, sudden darts, swirling/sluggish movements and loss of balance.…”

ABSTRACT:The toxicity of ethanol extract of Adenium obesum stem bark as a tool for aquaculture pond management prior to the stocking of desired fish species was evaluated in Clarias gariepinus over a 96-h exposure. The fish were exposed to 6.25 mgL -1 , 7.50 mgL -1 , 8.20 mgL -1 , 8.80 mgL -1 and 10.00 mgL -1 of the extract and a control in an acute static toxicity bioassay after performing a range finding test to determine the median lethal concentration (LC 50 ) of the extract. Exposed fish showed signs of changed behaviours with adaptive responses, respiratory distress and nervous compromise, including mortality in some of the exposed fish. The appearance and intensities of the observed signs were concentration and exposure period-dependent. An LC 50 value of 7.35 mgL -1 was established for the extract in the exposed fish where mean mortality was significantly (p<0.05) concentration and exposure period-dependent. The toxic nature of the extract in the exposed hardy fish can be exploited for effective aquaculture pond management against some unwanted predatory and weed aquatic organisms. However, the indiscriminate use of higher extract concentrations could seriously jeopardise the biodiversity of any aquatic environment. @JASEM

The present work studied the histological changes in gills, liver and ovaries of Tilapia fish (Saratherodon galilaeus) subjected to disturbed urban stream (sewage and industrial contamination) of two sites (ELaakada and EL-amerya) on Ismailia Canal during summer season. The most common lesions in gills were epithelial lifting, hyperplasia and hypertrophy of the respiratory epithelium, and lamellar fusion. Liver hepatocytes showed hypertrophied, cytoplasmic and nuclear degeneration, inflammatory cells aggregates and focal areas of necrosis. The ovary showed widened vitellogenic space filled with huge debris, the oogonial cells and immature oocytes were in the process of degeneration particularly at the ooplasmic level. The most sever lesions were comparatively in the liver. It is concluded that histopathology can used as a biomarker for study the effect of pollutants in organs of fish.
