IBM (NYSE: IBM) and Kvarøy Arctic (pronounced “Kwa-ray”) recently announced the major producer of Norwegian farmed salmon will join IBM Food Trust to enhance the traceability of its salmon and help foster consumer trust across their supply chain. Roblox how to fixx oldbaronmondo hack.
Information source: Kvarøy Arctic / Press release
Kvarøy Arctic is enabling all corporate buyers, including select Whole Foods Market stores in the U.S. and Canada, and restaurants to scan a QR code which will provide a provenance history for the salmon and the feed it was raised on. They will also be able to download images and video of the farms and see for themselves the conditions and animal welfare standards that Kvarøy Arctic upholds. A consumer app to provide insight into the quality and sustainability of the seafood will also be made available in the future.
In the past three months, Kvarøy Arctic has seen a dramatic increase in demand for fresh seafood in the U.S., shipping twice the volume anticipated at its February 2020 launch. In the previous year, demand for salmon grew even faster than the demand for beef and poultry as consumers increasingly look for healthier sources of protein.
To help meet this need, Kvarøy Arctic has joined IBM Food Trust, an ecosystem of food producers, distributors, manufacturers and retailers collaborating using a permissioned, permanent and shared record of food system data stored on blockchain. Kvarøy Arctic is also working with its feed provider BioMar to begin uploading supply chain data to the network, creating an immutable record of the feed used and the conditions where the salmon was raised, packed, certified and shipped to distributors around the world.
Kvarøy Arctic holds itself to high standards, for example using open ocean habitats that contain roughly half the population of conventional salmon farms. This gives them far more space to swim, and Kvarøy reports, ultimately results in a healthier, better-tasting fish. Kvarøy Arctic’s farms are also located in pristine ocean waters at the Arctic Circle, promote sustainable farming methods and are 100% certified by the Aquaculture Stewardship Council, an organization that identifies responsible fisheries using both environmental and social standards. Finally, Kvarøy Arctic’s Atlantic salmon is certified by the American Heart Association’s® Heart-Check Food Certification Program, giving consumers peace of mind that what they are consuming meets the nutritional requirements of the American Heart Association.
Blockchain has the potential to enable greater trust in the supply chain by creating a permanent, digitized chain of transactions that cannot be altered. This way, feed manufacturers, fish farmers, distributors and retailers can all access comprehensive product data in near real-time. Each member of the chain will download and use an app to scan each salmon lot at each point of receipt. Kvarøy Arctic can grant permission to distributor and retail partners, allowing them to see data about the grade of feed used, the population and density of the habitats the salmon were raised in, their age, harvest date and more.
“Blockchain is the future when it comes to ending fraud in the seafood industry. It is a level of transparency that shows our dedication to being the best of the best,” said Kvarøy Arctic CEO Alf-Gøran Knutsen. “The technology tracks a level of detail that helps us reduce food waste so we can feed more people in the world.”
“Our work with Kvarøy Arctic further builds on our progress in promoting transparency and sustainability in the seafood trade,” said IBM Food Trust GM Raj Rao. “IBM Food Trust is delivering the tools needed to collaborate across industries and take the action to preserve and maintain our global fisheries, while protecting the integrity of the seafood supply chains.”
Several prominent members of the seafood industry are now using IBM Food Trust to enhance traceability for products ranging from shrimp and scallops to smoked salmon, including the Sustainable Shrimp Partnership, Raw Seafoods and Labeyrie Fine Foods.
ATEA, a leading provider of IT infrastructure solutions in the Nordic and Baltic region, is also working with Kvarøy Arctic as the systems integrator.

Arctic grayling (Thymallus arcticus) is a species of freshwater fish in the salmonfamilySalmonidae. T. arcticus is widespread throughout the Arctic and Pacific drainages in Canada, Alaska, and Siberia, as well as the upper Missouri River drainage in Montana. In the U.S. state of Arizona, an introduced population is found in the Lee Valley and other lakes in the White Mountains. They were also stocked at Toppings Lake by the Teton Range and in various lakes in the high Uinta Mountains in Utah, as well as various alpine lakes of the Boulder Mountain chain in central Idaho.
Taxonomy[edit]
The scientific name of the Arctic grayling is Thymallus arcticus. It was named in 1776 by German zoologist Peter Simon Pallas from specimens collected in Russia. The name of the genus Thymallus first given to grayling (T. thymallus) described in the 1758 edition of Systema Naturae by Swedish zoologist Carl Linnaeus originates from thefaint smell of the herb thyme, which emanates from the flesh.[3]
Description[edit]

Arctic grayling grow to a maximum recorded length of 76 cm (30 in) and a maximum recorded weight of 3.8 kg (8.4 lb). Of typical thymalline appearance, the Arctic grayling is distinguished from the similar European grayling (T. thymallus) by the absence of dorsal and anal spines and by the presence of a larger number of soft rays in these fins. There is a dark midlateral band between the pectoral and pelvic fins, and the flanks may possess a pink iridescence. T. Animal crossing new leaf qr codes pink dress. a. arcticus has been recorded as reaching an age of 18 years.
Range[edit]
Native and introduced range of Arctic grayling, Thymallus arcticus in U.S.[4]
Arctic grayling are widespread in Arctic Ocean drainages from Hudson Bay, Canada to Alaska and in Arctic and Pacific drainages to central Alberta and British Columbia in Canada. They do not occur naturally in the Fraser and Columbia river basins.[5] There are remnant native populations of fluvial Arctic grayling in the upper Missouri River drainage in the Big Hole River and Red Rock basin ('Montana Arctic grayling'). Fluvial Arctic grayling have been reestablished in the upper Ruby River, a tributary of the Beaverhead River. The native range formerly extended south into the Great Lakes basin in Michigan. They occur naturally in the Arctic Ocean basin in Siberia from the Ob to Yenisei drainages and in European Russia in some tributaries of Pechora river.[6] Lake dwelling forms of Arctic grayling have been introduced in suitable lake habitats throughout the Rocky Mountains including lakes in the Teton Range in Wyoming and the high Uinta Mountains in Utah,[7][8]Cascade Mountains and Sierra Nevada Mountains as far south as Arizona.
Life cycle[edit]
Several life history forms of Arctic grayling occur: fluvial populations that live and spawn in rivers; lacustrine populations that live and spawn in lakes; and potamodromous populations that live in lakes and spawn in tributary streams.
The Arctic grayling occurs primarily in cold waters of mid-sized to large rivers and lakes, returning to rocky streams to breed. The various subspecies are omnivorous. Crustaceans, insects and insect larvae, and fish eggs form the most important food items. Larger specimens of T. arcticus become piscivorous and the immature fish feed on zooplankton and insect larvae.

Spawning takes place in the spring. Adult fish seek shallow areas of rivers with fine, sand substrate and moderate current. Males are territorial and court females by flashing their colourful dorsal fins; the fins are also used to brace receptive females during the vibratory release of milt and roe. The fish are nonguarders: the eggs are left to mix with the substrate. Although the Arctic grayling does not excavate a nest, the highly energetic courtship and mating tends to kick up fine material which covers the zygotes. The zygote is small (approximately 3 mm or 0.1 in in diameter) and the embryo will hatch after two to three weeks. The newly hatched embryo remains in the substrate until all the yolk has been absorbed. They emerge at a length of around 12 to 18 mm (0.5 to 0.7 in), at which time they form shoals at the river margins. The juveniles grow quickly during their first two years of life.
Conservation[edit]
Arctic grayling are considered a secure species throughout their range.[9] Although some populations at the southern extent of its native range have been extirpated, it remains widespread elsewhere and is not listed on the IUCN Red List of threatened species.
The fluvial population in the upper Missouri river basin once merited a high priority for listing under the Endangered Species Act (ESA) by the US Fish & Wildlife Service (FWS). This unique southernmost population is now extirpated from all areas of the basin with the exception of the Big Hole River watershed. In preparation for an ESA listing, the US FWS began implementing a 'Candidate Conservation Agreement with Assurances' (CCAA). This agreement protects cooperating landowners from being prosecuted under the ESA 'takings' clause so long as they fulfill specific obligations, spelled out in a contractual arrangement and intended to restore the dwindling population. Finally, in 2014 the FWS determined not to list the grayling under ESA, due to the effectiveness of the CCAA.[10]
The Arctic grayling is economically important; it is a 'key subsistence species'[11]:43 for the Iñupiat people of the Alaska North Slope, it is raised commercially for food and it is one of the most important species for Sport fishing in Alaska.[11]:47
