I am a sniffer. Of the crawfish I’ve sniffed, none have really had any discernible smell

Try the other end. :devil1:

I've heard that they excrete a chemical after being hooked that will warn off their buddies.  Hence, a lot of guys will keep smallies in their livewell until they leave an area.

I'd have to disagree with this due to the number of times I've had one on and had multiple others swimming with it trying to get the bait too.

Seen this several times myself. Sometimes following the hooked bass all the way to the boat without ever looking up.

What does a crawdad smell like? Do they all smell the same? Does a PA crawdad smell the same as a Wisconsin crawdad?

 

Can’t say I’ve had a Smallie smell like anything or smell out of ordinary. Have caught a lot of smallies. I’ve kept smallies in my livewell and have never opened the lid and get knocked to my knees with the smell of anything. 
 

I’ve caught a few Spotted Muskies while smallie fishing and they had a sulphuric smell to them. A few tiger muskies that had an odor but not as strong as the Spotted. Healthy fish showing no signs of a sickness. These were immediately released and skin (slime layer) not touched. Maybe that smell/excretion has to do with surroundings. I don’t know. 
 

Smell or no smell of smallies I keep my livewell washed, clean and flushed. I’ve had them hock up a bunch of crawdad parts while being in the tank. Can only imagine the smell of that in a day or so of not getting flushed out.

You can smell odors from the mouth and vent to determine if the bass is eating crawdads.

I wouldn't totally dismiss something like this, pheromones and olfactory cues play a big role in how animals and fish behave, a lot of things still probably unknown. I believe personally, that the smallmouth and crayfish are kind of co-evolved, so basically the smallmouth is born to be a crayfish specialist. Have seen fat sm with crayfish feces all over the place, but some of those same fish would have been caught on a topwater minnow imitation, so they may be evolved as crayfish specialists but they are of course still opportunistic.

Let’s add a little common sense to what might be an old wives tale.  Ever eaten a meal or string of meals loaded with garlic?  Ever hear about eating garlic or eating match heads keeps mosquitoes away?  Reason being what you eat in some instances gets excreted through your skin.  It’s not too far fetched to think that if a bass is eating crawdads or minnows which both contain high levels of oil, they could and would excrete a smell through their skin.  I know in my home waters it’s very easy to tell the bass that are feeding on Shad, they reek of Shad smell.  Just some food for thought.?

I guess it’s only fitting in the ‘circle of life’ that if smallmouth can exude a crawfish smell and lure them all out to their demise, that we anglers can then apply that same crawfish scent to our baits, luring those same bass to their demise, basically beating them at their own game…nature is so stupid ?

My older cousin talked me into touching a nine volt battery on my tongue to see if it was good. IT WAS!!! LOL. That dirty bugger.

Been studying this here anatomy chart.

Seems they left out that crawfish excretion zone.

It's the line next to the anal fin without a description. Anal fin area gives it away.

 

Or something...

Maybe the 'anal fin' should be labeled a 'vent fin'?

Maybe they inadvertently smell like Crawfish when they feast on them. But can they exude a smell to intentionally draw Crawfish into the open ? Probably not, but I don’t know and it would be one heck of a Science Experiment ?
