xDirty Posted January 7 Share Posted January 7 Quote Smallmouth excrete a chemical from their skin that smells like crawfish and entices crawfish to reveal themselves while investigating for the intruder. Im sure im not the only one who has heard this rumor. I call it a rumor cause have not been able to find a single scientific source. Im looking for information. How did this rumor start, is there any truth to the rumor and does anyone have a scientific study on the subject. 1 Quote Link to comment Share on other sites More sharing options...

2tall79 Posted January 7 Share Posted January 7 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. 2 Quote Link to comment Share on other sites More sharing options...

This concentrates on individual rumor. This is the opinion of a single person. I want to know who started this rumor and if there has been any scientific study on the subject at all.

Super User MN Fisher Posted January 7 Super User Share Posted January 7 The only places this is 'bandied about' is on Canadian fishing sites. There is no scientific study I know of that breaks down specific prey odors in the slime-coat of any species. <-Aquatic Biology major in college. 1 Quote Link to comment Share on other sites More sharing options...

This is more of the type response i was expecting to have, not the previous one. I have concluded the same thing so far, and it seems multiple people have copied the same exact sentence on various sites. I found this article that im posting below but that seems to be another copy and paste job by an author doing research on various sites without any scientific backing. https://www.idahostatesman.com/outdoors/fishing/article40868019.html 1 Quote Link to comment Share on other sites More sharing options...

Super User Team9nine Posted January 7 Super User Share Posted January 7 Looks like your article is hidden behind a pay wall, so I’m guessing no one here can read it. No idea where this got started, but weird theories get life and spread all the time on the internet. First, it makes no sense and would likely lead all crayfish to their untimely death - then the smallmouth would starve- lol - a smallmouth bass pied piper. Studies show crayfish react to smallmouth bass based on their perceived vulnerability to predation. Those that feel fairly secure in their habitat tend to go about their business a bit more regularly. Those that feel vulnerable restrict their behavior and movement. Additionally, they can use alarm cues to warn each other when predators are in the area, causing them to restrict movement or retreat further to avoid predation. 3 Quote Link to comment Share on other sites More sharing options...

When & Where applicable regulations allow, I totally do that. And to the best of my knowledge, it hasn't ever made a bit of difference, one way or the other. But I still do it. Because I'm a crazy person. At least I'm not in denial. 🤪 A-Jay 2 1 Quote Link to comment Share on other sites More sharing options...

My reaction was similar to Zona's if you caught that episode where he got pooped on. I don't recommend it. 1 Quote Link to comment Share on other sites More sharing options...

That other SM are supposed to be "warned off" by an excretion I have to call BS on that one. 😉 6 Quote Link to comment Share on other sites More sharing options...

Pound that area till they stop eating them come back later and get them for seconds. Quote Link to comment Share on other sites More sharing options...

Bdnoble84 Posted January 10 Share Posted January 10 I have no basis on science for any of this, but i could see it plausible that if they ate a ton of crayfish maybe they would develop a specific odor based on that diet? There are scenarios where that does happen. Again no just ification or evidence to support but thats what came to mind as plausible. Quote Link to comment Share on other sites More sharing options...

Of the crawfish I’ve sniffed, none have really had any discernible smell 1 1 Quote Link to comment Share on other sites More sharing options...
