THE INFLUENCE OF THE TEMPERATURE AND THE WATER HARDNESS ON THE TOXICITY OF HERBICIDE FUSILADE FORTE 150 EC TO PRUSSIAN CARP (CARASSIUS AURATUS GIBELIO BLOCH 1782)
Journal Title: Current Trends in Natural Sciences - Year 2017, Vol 6, Issue 12
Abstract
The temperature is an important physical parameter, playing the role of a natural catalyst, activator, restrictor and selector of the aquatic life. This study has been carried out in order to analyze the effects of the concentrations of the Fusilade Forte 150 EC herbicide (0.004 ml Fusilade Forte 150 EC/1 water, 0,008 ml Fusilade Forte 150 EC/ l water, 0,016 ml Fusilade Forte 150 EC/ l water) and calcium chloride (200 mg/l water, 400 mg/l water) on some physiologic indicators on the carp. The hardness of the water does not significantly influence the oxygen consumption of the carp individuals that are exposed to the action of the herbicide. The herbicide has had an inhibiting effect on the studied parameters for all the used concentrations, the toxic effect being less pronounced at high temperatures.
