Question:
If lightening strikes water, what happens to the fish? Do
the ones just near the surface die, or only the ones near where the
lightening struck....or do they all die...or are they all ok? Just
wondering. Thanks!

Jeans,
Certainly some of the fish die near the lightning strike point.
However, it is hard to say how large an area of the water is
affected as the energy in a lightning flash can vary over a
factor of 10. Because water is a good conductor of electrical
energy, the horizontal distance that the lightning energy would
travel along the water surface could be large. If I were in a
metal boat within a hundred feet of a lightning strike, I would
probably get a pretty good shock if I had my bare hand on the
boat. The depth of water affected also depends on the
amount of energy in the stroke.
