Acipenser Lore

Acipenser is a rock sturgeon from the Great Lakes who flew away from home to find a nice stream to inhabit, and found one in Idaho! They're now a lifeguard at a small summer camp/river guardian that keeps the camp safe from people who want to shut it down and put in a parking lot. They have a dragon form but don't use it so much as their bipedal one. They like to lead water hikes and roast marshmallows with campers as well as teach about local conservation efforts!

Some accuracy notes:

they're a Great Lakes sturgeon because of sentimental reasons but the range of sturgeon in northern Idaho is actually taken by acipenser transmontanus!

Also I gave them a jawbone because they need it to talk and eat urban developers.

Sturgeons do not have mullets in real life I gave them one because it's hot

Fish of the Day

Today's fish of the day is the lake sturgeon!

The lake sturgeon, also called the rock sturgeon, and known by scientific name Acipenser fulvescens is one of the best known North American sturgeon species! Found in and around the great lakes, and then across the Mississippi river and Erie canal. Found in 5 differing Canadian provinces and across 24 states stretching from Alabama to Michigan, and as far East as New York. These fish are benthic, spending their time along the bottom of the lake bed, but during spawning these fish will migrate thousands of miles to go back to the stream they were born in.

Like all sturgeon, they are considered living fossils, as sturgeon first appeared in the fossil record upwards of 150 million years ago, with the fish now appearing nearly identical to these ancestors. These fish can get 7 feet or longer, with most being only 4 to 6 feet in length, making them some of the largest sturgeon in North America. Their diet is made up of various invertebrates such as: larvae, small crustaceans, and worms, which they can find along the benthic lake and river beds. The 4 barbels found on these fish have taste buds, which are used to determine what is under their mouth, before they use their prehensile lips to suck up food. When food becomes scarce, these fish are known for migrating for better feeding, which happens semi frequently around the year.

The life cycle of the lake sturgeon is similar to that of most other sturgeons. They begin life as eggs laid in the location their parents were born, in fast paced river streams with lots of flat rocks. The eggs themselves are a bright yellow color, although as the eggs matures this will turn an olive and eventually brown over the course of about 2 weeks. Then they live as larvae only 10mm long, living in and around the dark underside of rocks. After this, as juveniles they will swim to lake environments, where they will spend the majority of their life cycle. These fish can live 55 years long in males and around 150 years for females, with sexual maturity being achieved at an age of around 10 years in males and 30 years in females. Breeding and spawning only happens intermittently every handful of years, and go through around 10 spawning seasons throughout their lifecycle.

For a fun fact to end on for these fish because I'm particularly fond of them, when they reach the stream they will spawn in, these fish are known to porpoise, jumping several feet into the air to end their long journey. That's the lake sturgeon everybody! Have a wonderful day!

i would love a fish… i love all fish but lately i’ve been real into freshwater game fish 🩵

Perhaps the best freshie of all time

Trick or treat!

I'll give you a lake sturgeon (Acipenser fulvescens)!

[rebeccathenaturalist]

Here in the Pacific Northwest, the iconic fish that we most commonly associate with the ecological devastation of dams is the salmon. However, sturgeons also face extinction due in part to these massive structures that not only change the flow and temperature of rivers, but can cut fish off from their breeding grounds. That includes in my home state of Missouri.

Sturgeons are really incredible animals. Their unique lineage split off from the rest of the fish during the early Jurassic, 175 to 200 million years ago. Sturgeons themselves can be comparatively ancient, with some individuals living 150 years. They may not breed until they are at least 25 years old.

Lake sturgeons (Acipenser fulvescens) are one of many species driven close to extinction by overfishing for meat and roe, as well as habitat loss and pollution. For the past three decades biologists have been reintroducing this species to parts of its historic range in Missouri, and for the third time since conservation efforts began they have witnessed these fish--now grown up--spawning. Previous observations were made in 2015 and 2022, meaning the recovery is still quite recent.

But it's proof positive that restoring habitat, once again, is one of the best ways we can help wildlife. Long may the sturgeon swim!

Conservation Efforts

Conservation of these species is crucial due to overfishing and habitat loss. Sustainable practices and regulations are essential for their survival.

FAQs

What is the difference between Atlantic and Pacific salmon?

Atlantic salmon are typically larger and have a more pronounced flavor, while Pacific salmon are known for their variety and rich, fatty textures.

Can sturgeon be found in freshwater and saltwater?

Yes, some sturgeon species are anadromous, migrating between freshwater and saltwater environments.

Is caviar only produced by sturgeon?

While sturgeon caviar is the most renowned, other fish like salmon also produce roe used in cuisine.

Conclusion

Understanding the types of salmon and sturgeon is crucial for appreciating their role in ecosystems and gastronomy. Conservation efforts are vital to ensure these species continue to thrive for future generations.

Sturgeon Caviar

Enjoy the taste of the finer things in life with delicious Sturgeon Caviar fresh from the cool waters of North America’s freshwater lakes and rivers. American Lake Sturgeon (Acipenser Fulvescens) mature sexually in 15 to 20 years, with weights that can run upwards of l00 pounds. These fish spawn once every 5 to 7 years and yield about 25% of their body weight in roe. The caviar Sturgeon produce is comparable in size, color, and flavor to Caspian Osetra.

Érdemes a Tisza Tavi Ökocentrumban megnézni őket. Gyerekkoromban a kert végében folyó Eszed patakban fogtunk sok nagyot. Az egyiket bevittem az udvarra, szaladtam be a házba, hogy

- Anyu, anyu, fogtam egy kétméteres halat a patakban, de nem tudom a nevét!

- Az Eszed tokja az. Menjél ebédelni.

Rég volt, elmúlt.

Conservation of Lake Sturgeon (Acipenser fulvescens)

Our Waterford substation Native species crew has begun their annual juvenile lake sturgeon survey in the western basin of Lake Erie.

This study, in conjunction with data collected fish equipped with hydroacoustic tags as part of the GLATOS project, attempts to learn more about the ecology of juvenile lake sturgeon in western Lake Erie. This week two juvenile fish were captured and tagged while sampling.
