Gila Trout: A Native Trout Conservation Story

Plip. That’s the sound of a barbless beadhead nymph falling into a glassy glide of Mineral Creek, a headwater stream of the Gila River in southwest New Mexico.  There’s a short drift over a stony run, barely time to mend your line. Then follows that transmutation of fish flesh to your forearm—the taut tug of…

Clearly, the coolest fish in the sea

With its clear head and large green eyes, the Barreleye looks like an alien with a glass bulb on its head out of a sci-fi film…why does a fish need a transparent head?

Stalking the Elusive Shoal Bass

Guest Author: Amy Cottrell Editor: Solomon David The sun began creeping up over the tree tops and casting morning shadows and specks of daylight on the water surface, slowly lighting up more and more of the heavily vegetated creek bank. We paddled the quiet corridor, antenna rotating side to side in front of me as…

Fishing for Native Trout Leaves a Special Longing

Craig Springer, USFWS “Longing is the heart’s treasury.” —St. Augustine From nearly anywhere in my Santa Fe County home, I have the most fortunate view of the Sangre de Cristo Mountains. It’s where the Rockies start in New Mexico. As I write this, day bleeds into night, that period when the Muses visit painters and…

Red Tide

Ocean waters are home to many dinoflagellates and other types of plankton. The problem arises when populations become…

Jurassic World Fishes [Swimming Today]

Sharp teeth, bizarre shapes, gargantuan sizes, and a family tree that dates back over 100 million years…I’m not talking about dinosaurs, but ancient freshwater fishes! Twenty-five years ago today (June 11, 1993), Jurassic Park debuted in theaters. That date is fossilized in my mind because I recorded the trailer on VHS (wow, talk about ancient)…

The ideal invasive fish

There are hundreds of non-native fishes in the US. Some become harmful invaders, while others have established, but aren’t causing appreciable negative effects. As human transport networks continue to facilitate new introductions, it makes sense to ask, ‘is there something special about certain fishes that make them invasive?’. This isn’t a new idea—plant ecologists have discussed…

Radios Reveal Wandering Habits of Smallmouth Bass in Oklahoma: Angler-funded research lends greater understanding of one of America’s greatest sport fish

By Craig Springer, USFWS About the time that redbuds flash their pretty pinkish blooms on eastern Oklahoma’s hillsides and gray streamside sycamores unfurl their fresh leaves the color akin to a wet lime, there’s something curious going on. And it goes mostly sight unseen. Smallmouth bass are on the move with the singular purpose of…
