Red Tide
Karenia brevis is the scientific name for a single-celled marine dinoflagellate known for its toxicity, which can manifest in high concentrations as a “red tide.” This dinoflagellate and the red tides that it produces are not new. Ocean waters are home to many dinoflagellates and other types of plankton. The problem arises when populations become…
The New GenX: A Tale of Water Pollution
Guest Author: Susanne Brander People in Wilmington, NC have stopped drinking water, from the tap that is, even though we have a water treatment facility, renovated just a few years ago, that boasts of the “latest and most innovative treatment technologies” on its website. Facebook has become dominated by parents exchanging opinions on reverse-osmosis filtration…
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…
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…
El Niño, warming up the tropics with some devastating global consequences

Inspired by your comments on our previous article, the most poisonous and venomous fish, we decided to highlight those other sea creatures that, despite not having a backbone, also pack a powerful toxic punch. 1. First on the list are the box jellyfish or…
Zebrafish help show how ‘BPA-free’ is misleading
By: Dana Sackett Zebrafish are small freshwater fish that originated in rivers from India. These fish share important biological properties with all vertebrates that make them useful in understanding how contaminants may impact other vertebrates in the environment, including ourselves. Logistically they are also useful because they are easy to maintain in aquariums, and they…
Estrogens may be feminizing a waterway near you
By: Dana Sackett “Clutching the bottle of water I had just collected from the Pee Dee River, I climbed the steep embankment back to our truck wondering how much estrogen we would find in our sample. We spent the better part of a month driving across North Carolina to examine a suite of chemicals called…
Some Unexpected Consequences of Climate Change
By: Troy Farmer, a postdoctoral researcher at Auburn University On a global scale, aquatic systems are warming. Average temperatures in the world’s oceans have been steadily increasing over the past 50 years. Given that the observed warming trends are predicted to continue, our job, as fisheries scientists, is to understand how fish are presently being…
Why aren’t insect aquaculture feeds more common?
Insects are an economical, environmentally efficient, nutrient rich feed that could reduce the need for wild caught fish feed or other plant-based protein feed additives in aquaculture. This seems like a win all around, right?
Where does the mercury in our fish come from?
By: Dana Sackett The answer to the question, “Where does the mercury in our fish come from?” can be a bit complicated. While most mercury in our air and water originates from burning coal and other industrial sources, the form of mercury released from these sources is usually inorganic, meaning not the form that we…
