Atacama Trench Snailfishes VS Abyssal Plains Assfishes!
The scene is set: two neighbors with very different ways of living. One is large, long-lived, free-to-roam, blimp-like. The other: small, shorter-lived, confined, butter-like. These are the people's fish, occupying international waters and places on earth that are quite impossible for us to truly experience from the perspectives of these amazingly adapted, beautiful fish. Get to know the "albatross" of the abyssal plain, the unfortunately (or fortunately?) named Robust Assfish, AND the Atacama Trench Snailfishes in our first ever compare and contrast episode. Our guest, Dr. Thom Linley, is Curator of Fishes at the Museum of New...

Northern Pike in Southcentral Alaska
Get the latest scoop on Northern Pike in Southcentral Alaska with Alaska Department of Fish and Game guest Parker Bradley.

We deep dive into a nuanced look at how species can cause harm when they're put into new places, and what's being done to detect and manage populations in a very large and logistically-challenging environment.
