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…

Talking trash in the deep sea

By: Anela Choy (guest blogger and postdoctoral researcher at MBARI) Plastic debris in the ocean is no stranger to headline news… Surfers gliding through waves filled with plastic in Indonesia. The world’s largest landfill in the middle of the ocean, a vast area otherwise deemed the “Great Pacific Garbage Patch.” Sea birds ingesting large amounts…

Plankton or Plastic?

By: Dana Sackett At the end of this article you will get to play a game that many aquatic species are playing these days: Plankton or Plastic? If aquatic animals get it right and choose plankton, they get to enjoy a tasty treat full of life-sustaining nutrition, if not, they fill the much-needed space in…

Using fish for sunscreen?

By: Dana Sackett The title of this post may produce images of holding up a fish like an umbrella to block the sun but the real meaning comes from natural compounds created by fish that can block harmful ultraviolet (UV) radiation. Recent findings have suggested that it may be possible to reproduce these natural benefits for humans….

Nutrients: how too much of a good thing can be bad

By: Dana Sackett Consuming too many nutrients is something many of us can understand following the holidays.  Similar to ourselves too many nutrients in streams, rivers, lakes, and oceans can cause major health problems.  In fact, excess nutrients that enrich plant growth in aquatic ecosystems has a special name: eutrophication.  While this term was originally…

By: Dr. Dana Sackett with contributions and edits by Dr. Daniel Madigan, an expert in the field of radioactivity in the environment. Articles ranging from fear-inducing hysteria to ‘everything is totally cool’ have been hitting the media about radioactivity in the Pacific Ocean over the last several years following the disaster at Fukushima.  This week…

As it turns out, what we don’t know can hurt us.

By: Dana Sackett Perfluorooctanesulfonic acid or perfluorooctane sulfonate (PFOS) is quite the mouthful and while, like me, you may have difficulty pronouncing it, chances are you, along with almost all of your surrounding aquatic environments, are home to these chemicals.  A potential problem considering that recent research has a number of scientists concerned about the prevelance, persistence…
