Well - can you smell anything under water? I can't and I bet fish can't either. Taste is the important sense, so it is flavours and not scents that count. Agree? Disagree?

Agree and disagree - I can't smell underwater because I didn't evolve to live underwater.
Smell and taste are interdependent in humans and I suspect the same can be said for many other animals including fish.
Fish don't 'smell' things in the same way we are familiar with but I think they still detect scent trails in the water.

Smell and taste are very similar, if you have no sense of smell you have a VERY limited sense of taste. So I sort of agree with you but scents and taste are detected by chemical receptors and there location determines if its a taste or a smell!

A fish has nostrils for what reason?

Apparently fish can smell underwater.

you're trying to attribute human senses to a fish - they "smell" and "taste" in completely different ways to us.
remember we live in a different medium to fish, if air was "thicker" we would smell and taste differently. probably like chicken

"Daddy, why does that fish smell."
"It doesn't smell son. You smell, it stinks!"
------------------
Yes, they do smell as Frothey say, in a different way. We can only taste sweet, salt, sour, bitter and umami. Everything else is because of smell.
How come salmon smell their way up rivers?

And Sharks can detect a drop of blood from a mile away in an ocean

Spot on. Gas (air) carries smell. Liquids carry flavour/tastes. Why do fish have nostrils? For the same reason I have nipples!

and in humans, sight from a recognition point of view.
if you blindfold someone, put a peg on their nose and give someone an onion to eat, they'll more than likely say they were eating an apple......

Same goes for cinnamon, Frothey.
A test was done where a persons nose was pegged, and they were then given a powdery substance. I think one of the 15 or so subjects identified cinnamon straight away. The 14 others couldn't identify what it was.......until their noses were unpegged. They identified cinnamon immediately.

As kids at school we used to pinch our noses when we were asked to eat things we did not like as that way we would not taste it….yes, smell and taste are linked. While a fish may not “smell” as we do it does “taste” the flavors carried on the water…I think its just down to an interpretation of the word “smell”.
It would be interesting to know how big a % of finding a bait is down to “smell/taste” and how much is down to sight. More and more I get the feeling during daylight sight plays a pretty big part.

It doesn't matter what you, as a human, do with your senses. You are talking about a fish that lives its entire life beneath the water where evolution has equipped it to use its senses to locate food, danger, location, shoal mates, breeding grounds and partners etc.
Of course they can smell, see, taste, hear and touch. They may even have other senses which we cannot relate to but that's for another thread.

Why do fish have nostrils? For the same reason I have nipples!
so you have nipples so you can detect scent in the water then Geoff !!!!!
They must get very sensitive after a dip in the sea lol

"olfactory (is that spelt correctly ?)" - That is!
"wether" - That isn't.
