they dont sleep. if they did, then they would die. when you sleep, you dont pay attention to what your doing. same with everything else that sleeps. so if a salmon were to sleep, then it could stop swimming and go back down river and since its not getting water through its gills, then it will die. so no i dont think they sleep.

 

hmm never thought of it that way.....then how do they conserve energy?

 

They go to sleep when I hit them with "THUMPPER"

 

I love this i could not agree more

 

they save energy by moving into slow moving water. thats why when your looking for water thats holding fish, you always look for water thats fast meets slow. when fish are tired, they look for the water thats got the least amount of strain on them. thats how they save energy. thats why most people always target the fast meets slow water.

 

Have no idea if its the same concept. But Orca whales never sleep either. How they rest is they shut down one side of their brain at a time. This lets that portion of the body rest while the other is still allowing the whale to function. When they are "sleeping" they go into a robot pattern and the packs get real close together and surface very frequently. . . Maybe the same?

 

Ya thats what i was always told...

 

I had a bluegill in a tank for 8 years and he went to sleep everynight......well at least he rested on the bottom without moving once it was dark.......his eyes didn't close though, lol.

Did you feed him espresso before you went to bed?

 

yes they do... Have you ever fished all day without catching one.... that's because they took a sabbatical ...

 

It was kind of interesting actually, he would be kind of tilted in the water with his head down on the bottom of the tank and his tail up in the air. If you turned the lights on in the room he would stay in this position for some time before eventually waking up and moving around.

This made me curious too but I couldn't find anything salmon specific.

"Some fish keep very still, experiencing a quiet period (quiescence) that you might call sleep. Scuba divers often handle reef fish in the middle of the night without startling them and can even lift some species out of the water before they awaken. Fish in home aquaria appear to be resting immediately after turning the lights on in a room that has been darkened for several hours. Unfortunately, fish have no eyelids so it is difficult to tell whether they are asleep or not."

"A period of rest during which volition and consciousness are in partial or complete abeyance and the bodily functions partially suspended; a behavioral state marked by characteristic immobile posture and diminished but readily reversible sensitivity to external stimuli."

 

one things for sure the coho off of the central oregon coast have all taken a lot of bong hits and are sleeping right now.

 

They take naps !!!!!!!!!!!!

 

That's why salmon die after they spawn!

 

A childhood friend of mine is now a physiology professor at an Ivy League school, who specializes in sleep physiology. According to him, nobody really knows why humans sleep. So why would we understand why fish don't?

 

Its nap time!!!:smash::smash::smash:

 

They go to sleep when I give the "Nighty Nite Stick"
