Fish can see, they can hear and they can really "smell". Their sense of smell means the difference between life and death.
They now make tiny fish bait pellets with a tiny rubber band that you slip over a fish hook. Via smell fish can be tricked to bite a hook.
FISH like most all living species are 100x smarter than humans want students to ever learn........JUST about everything living is as smart as a human and humans hate that.
Humans use the idea that if the living creature is STUPID, then that makes it great to just eat the thing.
IF a creature is super intelligent some humans have a harder time killing and eating it.
Fish are so smart it is hard to classify them compared to humans--------what makes a human greater predator is the ability to DEFY NATURE---or in simply words---HUMANS have the ability to not fight fair. It is as though humans were not designed to live on earth.It is as though humans are an invading specie......a "weed".
