I just thought of something of possible interest related to the effects
of removing fish from the wild.  Salmon runs in Washington ain't what
they used to be.  People are now speculating that the rivers and streams
may be missing a crucial nutrient source, so salmon hatchery employees
are trucking carcasses to streams and leaving them there.  These
carcasses are from fish which returned to the hatchery and would not
have spawned in the stream (some hatchery programs are very successful
number-wise).  

This isn't about removing fish from the wild, but it does suggest that
something as biologically signficant as huge salmon runs are an
important component of the ecology of the Pacific Nortwest.
