For those of you who missed my prior posts on the subject,
the "Kármán gait" is the explanation of the fluid dynamics
involved in a trout holding its position is moving/turbulent
water while expending little or no energy to do such.

Here is an excellent link to the "The Journal of Experimental
Biology" where the paper was published on the "Kármán gait".

There is also lovely underwater video footage of it in Ozzie
Ozefovich's, "Underwater World of Trout - Feeding Lies".

Ozzie also has wonderful underwater footage of trout feeding
off the drift too. The "drift" is a description of trout food
caught in the current that drifts by a trout's nose while
he is Kármán gaiting in his feeding lie.

I would love it if Ozzie would make up a screen saver of
some of his Kármán gaiting footage. But, then again, I'd
probably never get any work done.

eyes rolling



Hi Dave,

Is there some part of the The Journal of Experimental
Biology's paper that you disagree with? I would love
hear your criticism of it. The more about trout behavior
I learn, the better a fisherman I become.

Or, perhaps, you were just giving me a bad time. :-)
