WebDec 15, 1999 · The mechanisms of forward locomotion by fishes have been investigated through the use of models involving both steady-state and unsteady hydrodynamics. In the steady-state scheme, lift is created on both the up- and downstrokes by orienting the fin at an angle to the water ( Blake, 1983a ). Lift-based fins tend to be short-based and wing-like.
