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.
Stretches of the Yuba River in California were exposed to the impacts of gold mining in the 19th century that, while a blessing for the surrounding economy, weren’t so great for the environment. And the effects of that mining still impact the river and its surrounding landscape to this day.
In 2013, Chinook salmon stocking in Lake Michigan was cut by 50 percent, according to officials at the Michigan State University Extension. The move came after managers in state and tribal agencies realized that there simply weren’t enough baitfish for feeding all the fish.
Male bass with female reproductive parts have been becoming a more common find in waterways around the U.S. Even in national wildlife refuges, which are thought to be protected from human disturbance, male bass have been found to have eggs.
Spring, time to get the boats out of hibernation and get to bass fishing here in the North. The bass don’t mind cold water up here and the bite can be phenomenal just after ice out. However, many bass will seek out the warmest water they can get in. Finding that “warm” water can be very important even if it is just a couple degrees. A few sunny days and warmer-than-average temperatures can make shallow, black-bottomed areas the place to be in a hurry.
The Atlantic molly is an amazing fish and we have covered its abilities to survive before. But new research published in the journal Proceedings of the Royal Society B give new context to its durability.
For decades, fisheries biologists with the Minnesota Department of Natural Resources have been trying to restore wild steelhead populations along the North Shore of Lake Superior. These stocks, that historically have reproduced by swimming up rivers to spawn, have been devastated by overfishing.
