How does a fish
operate? · Propulsion
As anglers we are
usually concerned with the strength and the speed of a fish (propulsion).
Huge advantage over land-based animals as the medium (water) supports
most of their body weight, allowing their muscles to be used for propulsion
hunters (tuna, marlin) have intense reserves of stamina and the body
shape to convert energy into speed very efficiently. Short range ambush
fish (flathead, bass) don't need to cover vast distance, but require
rapid acceleration and considerable pace over a couple of meters.
Most species of
fish rely on body and tail movements for propulsion, few use the undulations
of other fins (only the very stiffest of fish like tuna propel themselves
with rapid tail strokes)
