 Après avoir regardé la publi indiquée par Laurent, il semble que l'hypothèse que l'énergie soit relative à la distance est juste
 
-WHeis, 1978
-Work for constant speed energy
-Thrust equal to hydrodynamic resistance R
-R=a/2*Af*Cd*V 
-a density of the water
-With Af=frontal area
-Cd=drag coefficient
-V relative velocity between the water and the fish
-Total work=R*D where D is the distance covered
