Cold water and sturgeon

Hi all,

Just a few pictures from my local site:

Trout feeding frenzy, or is that a trout ball!

Hope you enjoy them. Water temp is a cool 4 degrees!

Comments, suggestions very welcome

Adam

Hi Adam!

I really like the #2 one!! What is it ??

On #3 I would like to see the whole plane - otherwise it's really cool!

IMO pic's #4 and #5 could use a little backscatter removal.

Knowing that You took these in 4 C water temp add's for me a special extra when looking at them

Nice work and thanks for posting!!

Karel

Hey Karel,

The fish in #'s 1 and 2 is a Diamond back Sturgeon (Acipensir sp.)

You are right about the backscatter removal-I'll do some thansk for the feedback

Looks like a small prehistoric dinosaurfish

Nice sturgeon!!!! We have sturgeon here but the vis is < 1mm so I have yet to see one

Looks like a load of rainbow trout, Oncorhynchus mykiss, a Pacific species but introduced all over.

Have any nice brown trout, Salmo trutta, shots?

Tom

I really like the sturgeon also!

2nd Tom's comment, we have sturgeon here too, but in low viz.

Do your sturgeon jump or leap out of the water at a certain time of the year? Ours do and sometimes people on boats are injured.

Always love to see something different, thanks so much for posting,

Best, Carol

Hi again all

Thanks for the comments-yes we are lucky to have Sturgeon and good viz!

Ours don't leap-they are pretty much bottom dwellers. They are fairly accustomed to divers now, so you can get pretty close.

I've attached some more pictures below-same place and some Browns for Tom!

This is a different species of Sturgeon-with less noticeable markings, darker colour and a pointed nose. Still Acipensir sp, but I don't know it's full name.

Salmo Trutta

Enjpy, and comments welcome!

Adam

Reflection on #3 pic. is awesome and adds alot!

Adam; very nice shots, interesting to see.

I dive with sturgeon at the Seattle Aquarium, it's quite a treat to hand feed them. They are very gentle, like puppy dogs when they want to be fed, sort of. The tend to come up behind you and nail you in the kidneys to let you know they are there! Then do a very long, slow turn and come in for a half a herring. You feed them like you would a horse, they have a long sort of hoover vacuum tube mouth that extends out, suck the food up from an extended palm as their teeth are well inside their mouths.

They live very long lives and get enormous, I've seen them jump in a river in Oregon that were easily 15-20' long.

I've never seen them in the wild while diving and the diamond-back one is really pretty.

Thanks for sharing,

Jack

Hi

Not tried feeding them yet!! but here's a couple of photos showing the mouth you describe Jack, taken in the same place.

Mark

I wondered when you would get along Mark

Great Pics-I was out trying to get some similar today-but couldn't find the diamondback!

Hi Adam

Don't use Wetpixel much but couldn't resist when I saw your "cold water and sturgeon" forum!

Like your photos, esp close ups - we've not been up for a couple of weeks, 4'C last time!!

Must be warming up now!!

Incredible close up shots!!!

I think the third shot, the one with the reflection, is a Salvelinus or charr, possibly what is called a brook trout in the US, introduced to Europe as well. Salmonid introductions have gone both ways - there are many brown trout in the US.

Wow!!!

And vis too!

Nice! These are cool shots as well.

Very unusual.

Fantastic sturgeon & trout - thanks guys!

Since we are on the sturgeon theme, thought you might like to read/listen to these local news items:

NPR w/broadcast link

Sturgeon and Humans Collide on the Suwannee

Interesting pic of a gulf sturgeon (Acipenser oxyrinchus desotoi) "leaping":

Leaping Sturgeon Breaks Boy's Arm

Actually folks on the river get killed by colliding with them from time to time; usually on the Suwannee, but surrounding Gulf-saltwater/brackish areas also.

Again thanks for the interesting pics and data!
