<b>EVALUATION OF TOXIC EFFECTS OF XYLENE IN <i>LABEO ROHITA L.</i></b>

The aquaculture farming of aquatic animals is an important source of food in Asia and worldwide. Aquaculture includes a stream, a lake the ocean, or an estuary. Present research work aimed to estimate the toxic effect of xylene on Labeo rohita. For the experimental study, Fish were collected from Manawa Hatchery, Lahore, Pakistan. Forty selected fish were divided into different four groups. To compare the toxic effects of xylene in different concentrations were applied ranging from 5ml, 10ml, and 15ml xylene up to 30 days. The blood of fish was collected individually from every group using standard methods and blood samples of different fish samples were also tested through different standard protocols. It was found from results that the complete blood count of fish was negatively correlated with xylene, as white blood cell (WBC), red blood cell (RBCs), and complete blood count (CBC) reduce with an increase in the concentration of xylene. The results suggested that waste and or use of xylene should be controlled to avoid losses through diseases and toxicity in fish as well as other aquatic animals.
