Keep rooting for these aquatic underdogs—they've got quite the fin to stand on!

Humpback Chub (Gila cypha)

Have you ever heard of a fish with a noticeable hump on its back?

Meet the Humpback Chub, known scientifically as Gila cypha.

This unique fish is not just a sight to behold but also a species that’s faced its share of challenges.

Habitat Where can you find these intriguing fish?

They call the warm, fast-flowing waters of the Colorado River and its tributaries home.

Think of Lake Powell as one of their beloved hangouts—quite the aquatic haven.

Features What sets apart the Humpback Chub from other fish?

Lake Sturgeon (Acipenser fulvescens)

Hey there!

Ever been mesmerized by the giants of the freshwater world?

Well, let me introduce you to the Lake Sturgeon, often measuring a cool 4-6 feet and tipping the scales at a hefty 30-80 pounds!

These gentle giants have been around for ages—seriously, some can live between 50-100 years.

Can you guess their favorite hangout?

Yep, it's the Great Lakes and the vast Mississippi River Basin.

But despite their tough, bony exterior, Lake Sturgeons are in a bit of a pickle.

They've landed themselves on the threatened species list in many places.

Why, you ask?

Well, humans have been a tad overzealous with fishing, and we haven't been the best at taking care of their habitats.

Remarkable Features of Lake Sturgeon:

  • Lifespan: Live to be 50-100 years old.
  • Size: Typically 4-6 feet in length, weigh 30-80 pounds.
  • Appearance: They've got this prehistoric vibe going with a shark-like tail and an armor of bony plates.
  • Diet: Bottom feeders, munching on goodies from the riverbed.

They might not win any beauty contests with their elongated snoots and lack of pearly whites, but there’s something endearing about these underwater ancients.

For many years, these fish thrived, but not so much nowadays due to overfishing and polluted waters.

Talk about tough times in the water world!

Did you know that despite their name, Lake Sturgeons aren't just fans of lakes?

Quiet waters of rivers also make the perfect home for these fish.

Now, the good news?

Efforts are underway to give these sturgeon a fighting chance, including restocking programs in some rivers and lakes.

So, next time you're by a big, serene body of water, keep an eye out for the mighty Lake Sturgeon, slowly plowing through the water, just as it's done for hundreds of years.

Shortnose Sturgeon (Acipenser brevirostrum)

Hey there, have you ever heard of the Shortnose Sturgeon?

These ancient fish have been swimming around since the dinosaurs!

Yep, over 70 million years ago.

Pretty awe-inspiring, right?

They're one of North America’s rare gems and they're even smaller than their sturgeon cousins!

Now, if you’re thinking about where you might spot one, picture the Atlantic coast.

Their habitat stretches from rivers to estuaries, and yes, some of them even call lakes their home.

But here's the thing, they're holding on by a thread – they're endangered.

  • Habitat: Estuaries and rivers along the Atlantic, including lake systems.
  • Status: Endangered.

What's troubling these guys?

Well, like many rare species, they're up against habitat loss and pollution.

Imagine trying to dodge all that just to survive!

Did you know when sturgeons feel that spring in the water – when the temperature hits about 44.6–50°F– it signals them it's time to spawn?

And females, they don't go halfway.

They lay anywhere from 27,000 to 208,000 eggs!

But even with that many, their sticky eggs need clean places to attach, and well, pollution is like the worst roommate when it comes to cleanliness.

Here's a quick fun fact: the Shortnose Sturgeon is under NOAA Fisheries jurisdiction.

They've been looking out for them since 1974.

Kinda cool to have a government body looking out for you, eh?

I bet you're catching on that every fish counts here.

Let's keep our waterways clean and give these small sturgeon a fighting chance to keep growing for another 70 million years!

Kokanee Salmon (Oncorhynchus nerka)

Hey there, have you ever heard of the charming Kokanee Salmon?

These shimmering swimmers are a sight to behold and pack a whole lot of intrigue in their life journey.

Imagine a salmon that's ditched the whole sea-trekking business for a chill life in freshwater.

That's your Kokanee.

They are the inland cousins of the more adventurous sockeye salmon, living exclusively in the freshwater lakes of the Pacific Northwest.

They're like hometown heroes, staying put their whole lives in the clear, crisp waters they were born in.

What makes these salmon truly special?

Here's a quick rundown:

  • Habitat: They’ve set up shop in the picturesque, nutrient-rich lakes of the Pacific Northwest.
  • Status: It’s a mixed bag here. Unfortunately, some Kokanee populations are on the struggle bus, facing the 'threatened' or 'endangered' tags due to some humans playing fast and loose with their habitats and the intro of competitive species.
  • Features: They've opted for a landlocked lifestyle and generally have a four to five-year canter around the clock of life. They also have a grand finale - a one-time spree of spawning before they bid adieu!

But life isn't all easy swimming.

These little redfish are finding it tougher to thrive as their home turfs are morphing—thanks to us and our knack for changing landscapes.

Considering that an awe-inspiring process like spawning marks the end of their cycle, don't you think these little guys deserve our attention and care?

With their survival on the line, it's like they're starring in their own underdog story.

Let's cheer them on and protect their lake havens, shall we?
