In 2014, researchers conducted a regional study to map the quality, capacity and demand of anglers in several freshwater sources in NC and VA.
A 2014 study in Daisy Lake looks at the effects of forested watersheds on lake fish as they rely on the tree line for food.
Eutrophication can cause dissolved oxygen to crash which is a direct threat to the success of an aquaculture operation.
Whether fixed or mobile, an underwater camera allows a necessary window into a world otherwise difficult to access.
For accuracy and ease, dissolved oxygen sensors are the clear favorite over other measurement methods, but not all sensors are created equal.
Dissolved oxygen is vital to any healthy, life-sustaining aquatic system. And that includes aquaculture ponds and enclosures.
Monitoring and maintaining dissolved oxygen levels in aquaculture ponds is part of an ecosystem wide approach for raising aquatic animals.
How is dissolved oxygen (DO) measured in aquaculture? We cover the basics of sensor selection and maintenance on todays post.
Low dissolved oxygen can be a killer on aquaculture farms. Even when it’s not, it can halt growth, help spread disease and more.
Hydrogen peroxide can be used to boost crashing dissolved oxygen levels in aquaculture enclosures.
You can achieve healthy dissolved oxygen levels in aquaculture by aerating your ponds. How to do so is a matter of choice.
In aquaculture, the dissolved oxygen concentration rises and falls daily. Understanding this cycle can help you avoid problems from low DO.
FishSens answers 9 questions about monitoring dissolved oxygen and it's importance in aquaculture operations and fish farming.
By reviewing 85 million years of fish fossil records, researchers at Scripps Institution of Oceanography have found that the basic structure of the ocean ecosystem was able to remain fairly stable for tens of millions of years despite large environmental changes of the past.
South Dakota State University researchers have tagged more than 26,000 fish in the last three years during a study of Lake Oahe walleye. Plans are for one more year of tagging and an additional year beyond that of data collection to assess the lake’s walleye stocks.
In 1985, scientists discovered a walking fish living in a cave system in Thailand. The waterfall-climbing cavefish, Cryptotora thamicola, is completely blind and yet can make its way up an incline by using what closely resembles a tetrapod (four-limbed vertebrate) gait.
As humans, we can sometimes tell when we’re being lied to. A shift in gaze, lack of eye contact, and changes in voice tone are all good indicators that something’s up. But science is still working to understand how some fish can tell if they’re being deceived.
It’s kind of strange how fish can swim around with gills open directly to the water and not immediately get sick from all the waterborne pathogens swimming around them. It’s weird, but also pretty amazing.
Scientists don’t prefer to describe new species of anything with only just a few specimens to base their descriptions off of. But in the case of two new electric fishes discovered in Gabon, an African republic, researchers simply had to make due with the fish they had.
Besides its peculiar name, the Devils Hole Pupfish is a pretty peculiar fish. Just consider some of its key traits: large eyes, missing pelvic fins and reduced aggression behaviors. But how did this tiny little fish that inhabits a single spring cavern in the Mojave Desert in Nevada get...
