Underwater Cameras: A must-have tool for offshore aquaculture
Whether fixed or mobile, an underwater camera allows a necessary window into a world otherwise difficult to access.
Bacterial Coldwater Disease Less Prevalent In Hatcheries
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.
Building Salmon Knowledge In Alaska
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.
Great Lakes Angler Diary Lets Citizen Scientists Gather Fish Data
The Great Lakes region is so expansive that it’s hard for fisheries researchers to cover all of it. But, thanks to the modern smartphone technology many have at their disposal today, scientists are finding new ways to study places without ever actually being there. The predominant way is by utilizing citizen scientists, or volunteers, which are commonly anglers for fisheries studies.
Chinook Salmon Stocks Troubled In Lake Michigan
The Michigan Department of Natural Resources is considering another reduction in the number of chinook salmon being stocked in Lake Michigan, according to mlive.com. If the prized stock continues to go down, fisheries managers say that they may eliminate its stocking altogether.
Scientists Look To Prevent Another Sockeye Salmon Kill In Columbia River
Pretty much all options are on the table this year for preventing another massive sockeye salmon kill in Idaho’s Columbia River, according to the Associated Press. In 2015, less than 15 percent of the salmon stocked in the river made it to the water bodies they were migrating toward.
Nigiri Project Looks At Floodplains To Support Salmon Populations
For many years, experiments conducted on the rice fields of Knaggs Ranch, in California’s Yolo Bypass, have yielded accelerated growth rates for juvenile Chinook salmon, according to a release from the University of California, Davis. The experiments are part of the Nigiri Project, an effort that looks to assess how floodplains can support healthy populations of salmon.
More Chinook Salmon Stocked In Sacramento River After Low Years
Fisheries biologists have been trying to help endangered Chinook salmon in the Sacramento River for a few years now. But last year, after a horrible rise in summer water temperatures, about 95 percent of those fish that had been stocked were killed.
Intensively Monitored Watersheds Show Restoration Benefits
Since the 1990s, billions of dollars have been invested in works across the United States to improve stream health for fish. But many of the projects, through a lack of monitoring or recording of basic details, have provided little information for other researchers looking to learn from their approaches.
Salmon Anaemia Virus Found In British Columbia
Scientists with the University of Prince Edward Island have found evidence of a strong virus affecting salmon in British Columbia. The sickness is known as infectious salmon anaemia virus and is wreaking havoc on stocks of farmed salmon in the province.
