In October 2025, I created a series of drawings featuring “Sturge,” the sturgeon, mostly using the prompts from Inktober 2026. I had a lot of fun telling stories about Sturge, usually portraying them as a cartoon-like character.
For me, the Sturgeon has a deeper meaning. My late Father was born in 1932 in Pillau on the Baltic Sea. After World War II, the city was renamed Kaliningrad and is now part of Russia. He often told me of the significance of the sturgeon in the local culture of the time.
The sturgeon was so important for people in this area that a Sturgeon was prominently featured in the City Crest
Today, I live in British Columbia and am thrilled that sturgeon still inhabit the Fraser River.
Sturgeon, called c̓m’tus, play an important role in the Syilx culture of the First Nation in the Okanagan. According to Wikipedia, some scholars trace the origins of the mythical creature Ogopogo to First Nations folklore and broader water monster legends.
Truths About the World’s Oldest Fish. A 120-Million-Year-Old Mystery
According to the Yale Peabody Museum, sturgeons are ancient fish that first appeared in the fossil record between 174 and 201 million years ago, making them some of the earliest surviving species and true “living fossils” that have persisted long before and after the age of the dinosaurs. Their appearance—the elongated, shark-like bodies, the heterocercal tails, and the five rows of bony-plated armour—gives a glimpse into the deep past. Despite surviving mass extinctions, these giants now face a new challenge: adapting to a world shaped by human activity.
Takeaway 1: They Are the Ultimate Survivors (And Centenarians)
Sturgeons belong to the Chondrostei, a group of bony fish with primarily cartilaginous skeletons that has remained remarkably unchanged for over 120 million years. This biological strategy demonstrates longevity, though it carries a high cost in the modern era.
“Sturgeons are large, long-lived fish that are considered ‘living fossils’ because of their prehistoric history.”
Species like the Beluga (Huso huso) are known to live well over 100 years in the wild, while the Atlantic Sturgeon (Acipenser oxyrinchus) regularly reaches ages of 60 or more. However, this longevity is coupled with a precarious biological trade-off: late maturation and infrequent spawning. Males may not reach sexual maturity until they are 10 to 24 years old, while females can take up to 30 years. Furthermore, they do not spawn annually; many species wait between one and five years between events. This slow-motion life cycle means their populations are exceptionally vulnerable and take decades to recover from environmental shocks.
Takeaway 2: The Massive Disparity in “Giant” Fish
The Acipenseridae family ranges from small river sturgeon to massive fish rivalling ocean predators.
The Beluga Sturgeon (Huso huso): The largest freshwater fish. The record female in 1827 was 7.2 metres (23.5 feet) tall and weighed 1,571 kg (3,463 lbs). Females are 20% larger than males. In mass, Belugas rival Great White Sharks.
The White Sturgeon (Acipenser transmontanus): In British Columbia, this species is the largest freshwater fish, reaching huge sizes in the Fraser and Nechako Rivers.
The Shortnose Sturgeon (Acipenser brevirostrum): The smallest of the family, rarely exceeding 1.2 metres (4 feet) and 9 kg (20 lbs).
Takeaway 4: The Caviar Curse
In the late 1800s, demand for sturgeon meat and eggs—the world-famous caviar—led to a catastrophic collapse of their fishery by 1905. Today, these fish are protected by strict moratoriums; for instance, the Atlantic States Marine Fisheries Commission has banned fishing for the species until at least 2038.
Takeaway 5: Canada’s Own River Giants Under Threat
In British Columbia, White Sturgeon are conservation flagships, especially in the Nechako River. As bottom-dwellers, they are vulnerable. Dredging destroys essential habitats.
We can examine related species to assess the threats posed by climate change. According to NOAA, the Atlantic Sturgeon received a “Very High” overall vulnerability ranking. High sensitivity to ocean acidification and rising air temperatures is pushing these ancient survivors to their physiological limits.
A Future-Oriented Legacy
Sturgeons are more than relics; they are apex predators and key environmental indicators. Their presence tests the health of rivers and estuaries. They have travelled over 1,000 km to spawn, survived the Cretaceous asteroid impact, and witnessed humanity’s rise.
The question that remains for us is a sobering one: If a species can survive the dinosaurs’ extinction but now struggles to endure even a few decades of human-induced climate change and habitat loss, what does that say about the state of our waters? Protecting their “refuelling stations” and migratory corridors is no longer only a matter of conservation—it is about conserving a 120-million-year legacy.
