While stormwater runoff pollutants in general aren't great for aquatic animals, chemicals from tire particles are particularly harmful to salmon. A recent study now shows that permeable pavements could keep most of those toxins from ever reaching the fish.Ordinarily, when rainwater runs along city streets, it carries pollutants from those streets down the storm drains and out into the local waterways. One proposed method of addressing that problem involves replacing existing road surfaces – or building new ones – with…

Starre Vartan: I love a short cold-water swim in Puget Sound in Washington State. I start from a rocky shore near my home. Vartan: If I kept swimming just another 100 feet out, I could dive a few feet down through these clear waters into an underwater forest where animals such as shrimp, crabs and small fish like lingcod, rockfish—and maybe even salmon—like to live. Vartan: This is Scientific American’s Science, Quickly. I’m Starre Vartan. Kelp forests are made up of thick, undulating ribbons of brown algae that…

Observing a whole pen full of salmon at a fish farm will only tell you so much about their well-being. That's why Norwegian scientists have developed an implant that measures and records the vital signs of individual fish, who will serve as "sentinels."Created by Eirik Svendsen and colleagues at the SINTEF Ocean research institute, the cylindrical device measures 47 mm long by 13 mm wide. It contains a battery, microcontroller and memory card, along with sensors that monitor blood oxygen content, heart rate, activity…

An equipment failure killed 100,000 Atlantic salmon worth $5 million at the Sustainable Blue land-based salmon farm in Nova Scotia earlier this month, the company said Tuesday.A filter that removes carbon dioxide from holding tanks experienced a "structural collapse" on Nov. 4, the company told CBC News.The land-based salmon farm is the only one in North America with zero waste discharge thanks to its proprietary water filtration system which constantly recirculates water on-site.The fish kill has left the company unable…

A new paper published in Science says that as glacier ice melts, new land and rivers are being revealed in the ice-covered transboundary region shared by northern B.C., Alaska, and the Yukon. The peer-reviewed paper was a collaboration among researchers from Simon Fraser University, the Gitanyow Hereditary Chiefs' Office, the University of Montana Flathead Lake Biological Station, and Taku River Tlingit First Nation.Researchers say that for Pacific salmon, these emerging territories may present an opportunity to offset…

The man made flood that miraculously saved our heroes at the end of O Brother Where Art Thou were an actual occurrence in the 19th and 20th century — and a fairly common one at that — as river valleys across the American West were dammed up and drowned out at the altar of economic progress and electrification. Such was the case with Washington State's Elwha river in the 1910s. Its dam provided the economic impetus to develop the Olympic Peninsula but also blocked off nearly 40 miles of river from the open ocean,…

Researchers at NTNU’s Department of Biotechnology and Food Science are breeding bacteria-free fish fry, studying their growth, genes, and mucous membranes to understand the interaction between bacteria and fish. This could eventually lead to methods to prevent fish from getting ill, benefiting the fishing industry and our future food supply.Bacteria-free fish fry put scientists on the track to make fish more disease resistant.Researchers, including those from NTNU, are breeding bacteria-free fish fry. This is more…

Although salmon farms help take pressure off wild stocks, the penned fish do produce a lot of waste which is concentrated at one location. A new farm is exploring a solution to that problem, by raising salmon and kelp in adjacent pens.The experimental aquaculture operation is located in the municipality of Steigen, in Norway's Norland county. Norwegian fish farming companies Folla Alger and Cermaq are collaborating on the salmon aspect of the project, while the SINTEF Ocean research group is responsible for the kelp.The…

A federal decision to shut down 15 open-net Atlantic salmon farms around B.C.'s Discovery Islands is being lauded as a win for protecting wild salmon, and a significant blow to the fish-farm industry — all while reigniting a decades-old debate between industry and scientists.The decision from Ottawa came just weeks after a Fisheries and Oceans Canada (DFO) report found no "statistically significant association" between sea lice infestations among wild juvenile chum and pink salmon and the fish farms they migrate past…
