Behold the Mighty Bluegill: The People's Fish An essay on the important species that never gets its due

"For some families and communities, bluegill remain an affordable, local, and healthy source of food.

Restricting food access to these communities in the name of producing larger recreational fish, is….well, hard to justify."

My hypothesis is that they will be startled. Surely that suggests crystals were key in the evolution of all fishes! πŸ˜‚

Been wanting to write this one for awhile!

Conservation obsesses over rare species. But what about the common ones?

Bluegill are the fish almost everyone knows & caught as a child. But, how much do we REALLY know?

Dawg if I was a cookie-cutter shark and found out that my species could have been known as the "demon whale-biter" instead I'd be fuckin' *pissed*. Absolute nomenclatural humiliation.

Oyster farming along the Gulf Coast is becoming a big deal. Check out some of our School's interesting work on this topic πŸ‘‡

It's a glimpse into how aquaculture can be altogether sustainable and profitable, while also contributing to valuable cultural and ecological resources. Neat stuff!

Reminder that one of the nine North American sturgeon species is only found in Alabama.

Sadly, that species is on the verge of complete extinction.

It is definitely the most imperilled of all these sturgeons.

Why do students join Auburn University’s SFAAS program?

Because from waterways, to ecosystems, to the species in them, students graduate with real experience in aquaculture, fish health, and aquatic management that solve real-world problems in their next steps.
