Leitemperger, Jossiele published the artcileBehavioural and biochemical parameters in guppy (Poecilia vivipara) following exposure to waterborne zinc in salt or hard water, COA of Formula: C24H14Cl2O7, the main research area is Poecilia behavior locomotion salt water lipid peroxidation acetylcholinesterase; Environmental risk; Estuarine fish; Hardness; IBR; Metal; Salinity.
Therefore, this study aimed investigate the influence of salinity, hardness on Zn toxicity on the behaviors and biochem. parameters of the estuarine guppy (Poecilia vivipara). The fish were exposed to waterborne zinc (500μg L-1) in salt water (25 ppt) or hard water (120 mg L-1 CaCO3). For behavioral anal., the locomotive and exploratory parameters of fish in novel environment and light-dark tests were evaluated. We observed that exposure to hard water decreased the distance covered by the fish, and when zinc also present the vertical exploratory behavior decreased. When zinc was tested alone, an increase in the maximum speed of fish was recorded. Activities of antioxidant enzymes, levels of lipid peroxidation, protein carbonylation, total peroxidation and, reactive oxygen species content, antioxidant capacity against peroxyl radicals, non-proteins thiols levels, acetylcholinesterase and Na+/K+-ATPase activities were evaluated in the whole fish body. The integrated biomarker response was calculated for each parameter to aid in the interpretation of the results and indicated that hard water containing zinc had the greatest effect on the biochem. parameters of the fish. In general, neither salinity nor hardness were totally effective in protecting the guppy from the biochem. damage caused by exposure to zinc.
