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.
A giant Warsaw grouper caught in a coastal Florida fishing tournament weighed in at a whopping 347 pounds. With the monstrous total, the team catching it easily won the event, which took place in mid May.
Mosquitofish are considered pests in Australia, thanks to a failed introduction in which some thought the fish would help to control mosquitoes. But since then, the fish are relatively unwanted there, making them a great specimen for scientific study.
Got a thing for shad? Well, you would probably be in the minority these days just because it’s more difficult to find the fish than it once was. Back in the day, the early years of America, shad were much more abundant than they are now, according to a post from Atlas Obscura.
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.
After the release of the movie “Finding Nemo,” clown fish populations on coral reefs have been declining, presumably due to the popularity of having a fish that looks like the one from the movie in household aquariums. Scientists with the University of Queensland and Flinders University are worried that similar impacts could be felt on blue tang fishes with the upcoming release of “Finding Dory.”
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.
