Scientists with the Strategic Salmon Health Initiative (SSHI) have discovered three new viruses in chinook, sockeye and farmed salmon in B.C.
One of the viruses was hitherto not known to infect fish, according to the study, published in the journal eLIFe.
The extent to which the viruses may have an impact on fish health is not yet known.
“The discovery in dead and dying farmed salmon of previously unrecognized viruses that are also widely distributed in wild salmon, emphasizes the potential role that viral disease may play in the population dynamics of wild fish stocks, and the threat that these viruses may pose to aquaculture,” the study finds.
A raft of environmental bodies have welcomed a European Commission proposal for stricter limits on Baltic Sea fishing.
The Commission’s proposed total allowable catch (TAC) for Baltic Sea fishing in 2020 falls largely in line with scientific advice on limits which will maintain fish stocks; though TACs remain higher than scientists’ recommendations for salmon, Western herring and Eastern Baltic cod, which is subject to an emergency fishing ban until the end of 2019.
The Finnish Association for Nature Conservation’s Senior Advisor Tapani Veistola said: “The scientific advice on main basin Baltic salmon clearly states that commercial landings should be 58,900 salmon. The Commission proposal of 86,575 salmon is not in line with that advice. Ministers at the October Council should follow the scientific advice on Baltic salmon, not the Commission proposal…With some Baltic stocks in crisis, the Common Fisheries Policy deadline of 2020 for stocks to be managed sustainably and in the midst of a biodiversity and climate emergency, decisions taken during Finland’s presidencies of the EU and BALTFISH [the Baltic Sea Fisheries Forum] will be crucial.”
Now the shuffling begins at Alaska fisheries offices around the state as the impacts from back and forth veto volleys become more clear.
For the commercial fisheries division of the Alaska Department of Fish and Game, an USD 85 million budget, about half of which is from state general funds, reflects a USD 997,000 cut for FY 2020. Where and how the cuts will play out across Alaska’s far-flung coastal regions is now being decided by fishery managers.
“Now that the salmon season is about over we’re taking a good close look at this and what we’re going to put in the water next season. We’ve been assured we can look at our commfish budget in total and reduce the lowest priority projects,” said Doug Vincent-Lang, Fish and Game commissioner.
A Scottish start-up using shellfish to slash plastic pollution has won a game-changing investment from the Scottish Investment Bank and Sky Ocean Ventures.
Biotech business CuanTec is to drive the “significant” cash boost into final formulas and pilot production of its biodegradable, compostable and biodegradable food wrap.
Made from biopolymers harvested from waste shells sourced from Scotland’s aquaculture industry, the sustainable product promises an ethical alternative to single-use plastics and, its makers hope, become a go-to item for both domestic and commercial kitchens worldwide.
Diadromous species use freshwater environment for reproduction and marine as a feeding area or vice versa. While some diadromous fish species (e.g. salmonids, eel) are famous around the globe and highly valued, others attract far less attention from policy-makers, scientists, or stakeholders but are likely to make crucial contributions to complex marine, transitional, and freshwater ecosystems.
Many diadromous fish species have threatened status and suffer from environmental degradation and human-induced changes, especially in reproduction areas. The main threats to diadromous fish include migration barriers (e.g. dams), river construction, local inputs to rivers, lagoons, and estuaries (pollution, eutrophication, acidification), habitat loss, and overfishing.
The latest publication in ICES Cooperative Research Reports series, CRR No.348 Data-limited diadromous species – review of European status, updates the status and distribution of selected species that have completely or partially diadromous populations.
The “Aquaculture Cages Market” 2019 report is presented for each solution type, application segment, enterprise size, deployment type, service and regional market. Research analysts and experts have utilized excellent market research tools such as SWOT analysis, Porter’s Five Forces analysis, PEST analysis, and Primary and Secondary research analysis to define, describe and evaluate the competitive landscape of the Aquaculture Cages Market.
There are speculations about Global Aquaculture Cages Market to strongly dominate the global economy with a substantial growth rate in the coming years. Promptly developing industry infrastructure, increased product commercialization, and drifting demands of the Aquaculture Cages are strengthening Aquaculture Cages industry’s footholds to become more influential and significantly contribute to international revenue generation.
The fisheries union wants an emergency meeting with the federal minister to talk about a fish we do not often hear much about.
Mackerel are plentiful off some areas of Newfoundland according to the FFAW, but it says federal science has not kept up with the changing times.
Union president Keith Sullivan says it’s a cyclical fish but DFO science is confined to larval studies off Cape Breton. He says that used to work okay, but in recent years harvesters have seen large amounts of mackerel off Newfoundland’s northeast coast and in the Gulf of St. Lawrence.
