>A very localized, <10 mi, fish kill of predominately Freshwater Drum has
>been occurring on the Ohio River for the past 10 days.  Two to three
>thousand indiduals have been counted.  All sizes.  Ninety-five per cent of
>the kill is Freshwater Drum...a few other species, Sauger, Walleye, Catfish,
>Hybrid Striped Bass have been observed.  Zebra mussels occurr in the river
>at this location.  A 17 year hatch of cicadas is also occurring in this
>area.  Native unionids are not showing stress.  No visible damage apparent
>on external examination.  No molluscicides have been reported in use since
>October, '98.  Initial results of bacterial analysis negative.  Fish
>observed swimming disoriented in shallow water, < 1m.  When spooked, fish
>swim to deeper water, then return to shallow, shoreline areas.  Some
>individuals can be collected by hand.  Any ideas, thoughts, suggestions?
