Considering that salmon can swim against the current, and leap waterfalls, it does imply a certain hydrodynamic advantage.
After sea trails with the USS Albacore ( tuna), the U.S.NAVY determined, in 1953, that all future submarines would have ichtyoid ( fish-like ) external hulls.
Anyone who's watched ' The Hunt For Red October', has seen the circa- 1972, Soviet, Alpha / Akula-Class,nuclear submarine hull hydrodynamic technology. World's- fastest, high-pressure reactor submersibles. Biomimicry.

nose on Honda

I built a slip-on over fascia for the '84 CRX. It extended the length 6-inches, enlarged the side radius, lowered the forward stagnation point, reduced the cooling inlet, and faired in all the concavities.
It did helped top speed a little. The tail extension however, was good for most of the speed increase.

CRX nose side view

Here's a different view.

Again, the back of the car was the money-maker.

'optimum nose' 1968-style

Here's a low quality image of R.G.S. White's aerodynamic 'recipe', he came up with at MIRA, and published in 1968.
If you look at E-1 on the chart, you'll see a resemblance to Hucho's 'Optimum' nose.
This shape traces back to World War- I.

WW-I nose

Here is the Airco DH.2, with the similar nose.

The nose is the only thing that DH.2 has going for it.
