'Fish exposed to anti-anxiety drugs become aggressive'
BOSTON: Wild perch living in water tainted with a commonly prescribed human anti-anxiety drug aggressively feed, shun other fish and become careless, according to the results of a study presented at a meeting of scientists on Thursday. "We knew there was a pharmaceutical that was present in the environment that had behavioral-changing capabilities in humans, but what could this do to fish?" said chemist Jerker Fick of Umea University in Sweden. The findings highlighted the potential ecological implications of even trace amounts of psychiatric pharmaceuticals that are excreted in human urine and survive wastewater treatment plant processes, scientists told a meeting in Boston of the American Association for the Advancement of Science. For the experiment, scientists divided 75 wild European perch into three groups. The research appears in this week's Science magazine.
