fish population analysis. Such efforts should ex-
pand the state of fisheries science and the art of
water management by clarifying the effects of
population-limiting habitat events and water
temperatures on movement, growth, and mortal-

Current emphasis in many federal agencies is
on ecosystem planning and management. It is too
early to tell how IFIM techniques may be utilized
in this current push, but if utilized, applications
must be broader in geographic scope andempha-
size longer time horizons than have typically been
employed in the past.
