#Scaphirhynchus albus

[sturgeonposting]

Hi I love your blog I would like to request some pallid sturgeon content as they’re native in my home state and are endangered!!

Pallid Sturgeon

Scaphirhynchus albus, commonly known as the pallid sturgeon, is native to the Mississippi and Missouri River deltas in the United States. Of the three members of the family Scaphirhynchus, the pallid sturgeon is the largest. This lady regularly grows between 3 and 5 feet long — by no means a giant among sturgeon, but an impressive length nonetheless. Pallid sturgeon enjoy a seasonal diet: insect larvae during their spawning months and minnows when the insect larvae have all matured or been eaten. The pallid sturgeon is named for its beautiful pale cream coloration. These gals are critically endangered in the wild, but conservation efforts are reducing the strain on their population. A healthy stock of breeding individuals exist in various hatcheries and juvenile pallid sturgeon are regularly released into the Mississippi and Missouri rivers.

I'm working on a fantasy worldbuilding project but I don't understand worldbuilding so I'm making 5 important things each based on a different pairing of Sturgeon Species & offputting Jerma985 clip. Conveniently I found this blog right before deciding that this idea stunk bad, so I wish to request 4 Sturgeon Species and 1 offputting Jerma clip from you.

I don't know what the fuck ANY of these words mean but im gonna require you by law to let me im on your secrets and explain everything you just said. I want in on the ground floor of this wild worldbuilding project like my life depends on it.

Huso huso, the Beluga Sturgeon (notable for being the ideal source of luxury caviar)

Scaphirhynchus albus, the Pallid Sturgeon

Pseudoscaphirhynchus fedtschenkoi, the Syr Darya Sturgeon, not seen in the wild since the 1960s.

Pallid Sturgeon (Scaphirhynchus albus)

The Pallid sturgeon is a “living fossil” - the species has been around for millions of years. Rare and mysterious, this bottom-dwelling freshwater fish eats smaller fish and young aquatic insects.

The pallid sturgeon experienced a dramatic decline throughout its range since the mid to late 1960's. Nearly all of its habitat has been modified through river channelization, construction of impoundments, and related changes in water flow. These changes blocked the pallid sturgeon's movements, destroyed or altered its spawning areas, reduced its food sources or its ability to obtain food, and altered water temperatures and other environmental conditions necessary for the fish's survival

idk where you live but come to Shedd Aquarium in Chicago! You can touch Atlantic Sturgeon and Lake Sturgeon there

Going to go ahead and answer all three of these in one post. I wish I could go visit the Shedd Aquarium and pet the sturgeon but unfortunately I live in Georgia (USA), which is quite a walk from Chicago. You have no idea how heartbreaking this is for me, as it is one of my life’s goals to touch a sturgeon and experience the feeling of their scutes for myself. That being said, you have one of the coolest jobs ever. If you ever get a chance to photograph the sturgeons at Shedd, I’d love to see them — especially the pallid sturgeons, as rare/ endangered as they are. I am so jealous that you get to watch them eat! Another one of my life’s goals: seeing those protrusible mouths at work. I hope they treat you well at the aquarium.

how many sturgeon species are there?

There are 28 extant species of sturgeon, organized into 4 genera: Acipenser, Huso, Scaphirhynchus, and Pseudoscaphirhynchus.

-

Genus Acipenser contains the fish that come to most people’s minds when thinking of sturgeon: lake sturgeon, Atlantic sturgeon, white sturgeon, European sea sturgeon, etc. This is the largest genus of the family Acipenseridae, containing 20 species of sturgeon. Sturgeon in this family can be found in North America, Europe, and Asia.

(Atlantic sturgeon, A. oxyrynchus)

-

Genus Huso has only two members: beluga and kaluga. They are native to Russia and the surrounding parts of Eurasia. There is some argument that these fish should be included in the genus Acipenser. Unlike the members of genus Acipenser, whose protrusible mouths face downward, sturgeons in genus Huso have forward-facing protrusible mouths.

(Kaluga, H. dauricus)

-

Genus Scaphirhynchus contains three species of fish: shovelnose sturgeon, pallid sturgeon, and Alabama sturgeon. Scaphirhynchus means “spade snout”, in reference to these sturgeons’ long, flat, shovel-like snouts used to dig along river beds for food. This genus of sturgeon is native exclusively to the Missouri, Mississippi, and Alabama rivers in North America.

(Pallid sturgeon, S. albus)

-

Genus Pseudoscaphirhynchus is native exclusively to the Aral Sea system in Central Asia. This genus has three members as well: the Amu Darya sturgeon, the dwarf sturgeon, and the Syr Darya sturgeon. Like genus Scaphirhynchus, these fish have shovel-like snouts. Sturgeon in this genus are very small compared to sturgeon in other genus; the largest Pseudoscaphirhynchus sturgeon reach about 30”, excluding tail filament.

(Amu Darya sturgeon, P. kaufmanni)

-

Most species of sturgeon are endangered in some capacity. Many of the sturgeon mentioned in this post are critically endangered, with no individuals being spotted in the wild for many years.

It breaks my heart to think that we are slowly losing more and more species of these beautiful fish. But interest in their well-being is the first step to conservation, and that’s what I hope to cultivate here at sturgeonposting. Sorry to get all sappy at the end. I just love these guys. Long may the sturgeon swim.
