Historical
records
of
abundance
of
special
status
fish
species
in
the
Bay­
Delta
region.
These
historical
records
were
used
to
estimate
current
abundance
and
to
estimate
population
restoration
targets
that
would
represent
restoration
of
abundance
for
each
species
to
pre­
decline
levels.
Current
abundance
and
restoration
targets
were
used
in
estimating
a
$/
fish
value
for
special
status
species
in
the
Bay­
Delta
region.
