A Plate of Lies

Guest Blogger: Meghan Fox; Think you ordered the Mahi Mahi for dinner? Think again! It is now very common for restaurants and food vendors to serve a fish that has been misidentified or mislabeled…

Blog Biodiversity: Related Species in the Scicomm Ecosystem

It’s my first semester teaching Evolution & Ecology at Nicholls State University; with plenty of challenging and complex topics to tackle, I’ve also been given the latitude to integrate more science communication (scicomm) into this upper-level biology course. We’ve included Twitter and popular science articles alongside analyses of natural selection, genetic drift, and traditional scientific…

Coming to ‘terms’ with species invasions

Believe it or not, fish don’t care what we call them. However, terminologies associated with certain species can affect how society perceives their importance and impact. Naturalists have been interested in the effects of species introductions just as long as we have been moving species around. In that time, species introductions have had a variety…

A Breath of Fish Air

I recently migrated from Michigan to Louisiana to join the faculty at Nicholls State University as assistant professor. Moving from the Great Lakes to the bayou is inevitably laced with logistical concerns; in this case they included mobilizing myself, my wife, all our stuff, and…my fishes. That’s a two-day trip across ~1200 miles, but I…

Hurricane effects on fish…Revisited

by Troy Farmer, guest writer Given the active Atlantic hurricane season of 2017, now seems like an appropriate time to revisit a topic previously covered by the Fisheries Blog: hurricane effects on fish. Hurricanes impact our society in numerous ways, as many along the U.S. Atlantic and Gulf Coasts are currently experiencing. Given the destructive…

Great Lakes, Great #SciComm

Co-authored by Katie O’Reilly, Nicole Wood, and Solomon David #SocialGreatLakes: Communicating Great Lakes Science through Social Media was a special session at the 60th annual meeting of the International Association for Great Lakes Research held in Detroit, Michigan, from May 15-19, 2017. During #SocialGreatLakes, eleven speakers from a wide range of backgrounds and disciplines shared their…

Happy BOFFFF Day!

While mama fish may not have the same maternal instincts of our own dear mums, they do their part to sustain fish populations, particularly BOFFFFs. “What is a BOFFFF?” might you ask…A Big Old Fat Fecund Female Fish.

Yellow Perch and the hypoxia Goldilocks zone

It may seem obvious that suffocation is not good, but determining a fish’s tolerance for low oxygen is increasingly important as hypoxia increases worldwide. Hypoxia (low dissolved oxygen concentrations) occurs naturally—it develops in the hot summers and cold winters beneath ice in small lakes and ponds. Hypoxia can also occur as a result of human…

How climate impacts microorganisms and why we should care

By: Dana Sackett As Earth Day approaches, it seems timely to pause and examine some of the natural processes that enable life on Earth.  Remarkably, this big topic requires us to take a look at some of the smallest organisms on the planet.  Microorganisms (or organisms that cannot be seen with the naked eye such…

Spawning in strange waters: how hybridization affects native fishes

By Ed Kluender, guest blogger Hybrid creatures are one of the most common tropes of both goofy and great horror movies (think The Fly or countless werewolf movies), and plenty of them are at least half fish – Creature, Piranhaconda, and the Sharktopus franchise. Most of those films have a pretty shaky basis in reality,…

The value of a species

By: Dana Sackett According to some scientists the earth is currently undergoing the sixth mass extinction crisis in the last half-billion years.  Some have described this current crisis as the largest loss of plants and animals since the dinosaurs 65 million years ago.  With so much loss it is hard to understand how these extinctions…

Drought and pollution

By: Dana Sackett As an environmental scientist I can honestly say that I am very concerned for the future of our planet and ourselves.  I cannot emphasize enough the reality of climate change, that it is human-caused (and therefore that we can do something about it), and that we definitely need to do something about…

Fish biodiversity by the numbers

I was recently asked why I study stream and river fishes. Of course I rattled off several of the high points about threatened habitats, high biodiversity, and simply cool fish. But that question prompted me to reflect on why I do what I do, and I decided to go back to ‘square one’– the well-accepted…
