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.
Investigators at Mississippi State University say that it’s important not to underestimate different habitat types after finding prehistoric fish near the spillway in the Sam D. Hamilton Noxubee National Wildlife Refuge. They have found unexpectedly high numbers of paddlefish, a fish typically found in larger waterways.
The effectiveness of fish ladders can be debated, but that hasn’t stopped a few professors at South Dakota State University from designing some to help fish in their state. Over last summer, they worked to test the effectiveness of their ladder design for aiding fish passage.
Researchers use all sorts of tools to study fish, including dyes. Those had been used on many different species, but never crappie -- until now.
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.
Bacterial coldwater disease threatens wild and hatchery-raised salmonid fishes around the world, as well as the economic impacts that they offer. The disease is unfortunately spread through both contact with other fishes as well as through sexual reproduction.
Researchers at the University of California, Santa Barbara, are partnering with salmon experts around Alaska to make it easier to share findings about the fish, according to a release.
The fishackathon is an interesting competition that began in 2013. Back then, it didn’t have too many competitors. But it has blossomed into a big event in just the past few years.
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.
We’ve reported before on the quickness with which some species of sticklebacks have been able to evolve. A new study adds yet more proof that sticklebacks are amazingly quick at adapting to changing conditions, this time with their eyes.
