Experimental evaluation of fluridone effectiveness on fish productive aquatic ecosystems



Experimental evaluation of fluridone effectiveness on fish productive aquatic ecosystems



Journal of Aquatic Plant Management 27: 24-26



A man-made pond containing water from the nearby lake Mitrikou (N. Greece) populated with carp (Cyrpinus carpio L) was sprayed with an aqueous formulation of fluridone. Shortly after application. Cyanophyceae decreased drastically and they disappeared after two months. Fluridone levels in pond water decreased rapidly from 2891 ng/L to a value below its detection limit after the 60th day. Residues of fluridone in edible parts of fish reached a maximum of 484 .mu.g/kg on the 13th day and decreased steadily thereafter to 30.7 .mu.g/kg on the 84th day after application. No fluridone metabolite was detected in any fish sample. Although neither pathological findings nor histological features were observed in fish, further experiments appear necessary to establish whether fluridone may adversely affect carp eggs and fry.
