Thanks Hassann for your response. You may be right an industrial leak could explain the fish kill but since there appears to be only one kind of fish affected it is really a mystery. The birds are another issue.
Your right Mayaanjali if there is something in the environment that is that selective it would be very scary. The lightning strike explanation doesn't seem to fit the condition of the remains of the birds. It is very strange.
Thanks for the tip Max. I think you are right...there does seem to be some very strange happenings going on in the world these days.
