The 2016 Oregon Department of Fish and Wildlife annual electro shocking survey of fish populations in the upper Wild & Scenic section of the Crooked River revealed that, during the past year, the wild redband trout population suffered a catastrophic 86.4 percent reduction in numbers while the native mountain whitefish mortality was an alarming 45.3
Plastic is the predominant type of manmade debris found in rivers and oceans today. Between 60 and 80% of all marine debris is comprised of petroleum based plastics. Despite the fact that plastic pollution is a relatively recent phenomena, the problem has reached the far corners of the global oceans. Most of the obvious plastic
Researchers who work in wetlands in Michigan are taking a new approach to invasive plants. They’re harvesting them for fertilizer and fuel. When you’re in the middle of the Shiawassee National Wildlife Refuge, you don’t realize how massive it is. It’s 10,000 acres of marshes and bogs, forest and farmland. To put the size in

Osoyoos Lake is located in Osoyoos, British Columbia and Oroville, Washington; making it an international lake. The Boundary Waters Treaty
Treasure Coast governments spray more than 100,000 gallons of weed- and bug-killing poisons yearly at sites where the runoff can flow into waterways, but with minimal regulation, there main guideline is “follow the label instructions.” Agencies and manufactures insist the chemicals sprayed in marshes, canals and ditches are safe, but no one tests for residue
Herbicides, hormone-disrupting chemicals, as well as pathogens and parasites in the water, are the most likely causes for the decade-long decline of prize game fish in the Susquehanna River, a new study by state and federal agencies says. The study by the agency, the Pennsylvania Fish and Boat Commission and six partner agencies is the
During a comprehensive fish survey which included spring, summer and fall netting and electrofishing surveys, Greg Matzke, a fisheries biologist for the Wisconsin DNR discovered that all of the lake’s largemouth bass were older than 5 years of age.

The war against milfoil in Lake Sunnyside, New York has largely been won — but at the cost of leaving the lake vulnerable to invasion from another plant. Now, curly-leaf pondweed is taking over the lake, and stewards must fight that one too. The problem was that milfoil occupied nearly all of the shoreline, the
