Native freshwater fish diversity in the Murray-Darling Basin could be under serious threat from climate change in coming decades, a new study has found. This loss of biodiversity could result in a further decline in the health of the Basin.
The study, which has been published in PLOS ONE, was co-led by Griffith University researcher Associate Professor Mark Kennard from the Australian Rivers Institute and visiting Brazilian PhD student Anielly Oliveira.
Also involved were Brazilian collaborators from the State University of Maringa, the Federal University of Goias and the Federal University of Technology Parana, as well as Australian collaborators from La Trobe University and the NSW Department of Fisheries.
The North America Aquaculture market is accounted to US$ 6,432.8 Mn in 2018 and is expected to grow at a CAGR of 4.8% during the forecast period 2019 – 2027, to account to US$ 9,685.1 Mn by 2027.
The US is dominating the North America aquaculture market, followed by Canada. The demand for aquaculture is growing in the US, owing to increased consumer awareness related to health benefits associated with the seafood. Aquaculture has high protein content due to which it is gaining more acceptance by a larger customer base. The shift in consumer lifestyle along with inclination towards healthy food products, is also expected the growth of the market across the US. The manufacturers in the region are focusing more towards innovation and development to boost the growth of North America aquaculture market.
Critics of hatchery-raised fish claim the hatchery-rearing process affects fish genetics negatively, but Pahsimeroi Fish Hatchery Manager Doug Engemann said it’s more complicated.
At an Oct. 22 2019 panel discussion, Trout Unlimited scientist Helen Neville said raising fish in hatcheries isn’t a viable option to replace decreasing numbers of salmon in the Salmon River. She said the domestication process affects the DNA of fish because being raised in a tank adds natural selection pressures not seen in a natural environment.
Engemann, who has been with the Idaho Department of Fish and Game for 32 years, said these pressures can affect fish, but they affect some fish more than others.
The head of news at BBC Radio 5 Live, Jonathan Crawford, issued an apology after the Scottish Salmon Producers Organisation (SSPO) complained about Campbell’s broadcast earlier in November 2019.
In two programmes, Your Call, which he presented on November 6, and then on 5 Live Breakfast the following day, he claimed the Scottish salmon sector was ‘highly polluting and unregulated’. He also claimed farms were ‘terrible for the environment’.
The SSPO refuted the claims by Campbell as wrong, misleading and factually inaccurate, and argued that he had breached the BBC’s editorial guidelines, both in terms of accuracy and impartiality.
Lower catches for halibut appear to be in the forecast for 2020 and beyond.
At the International Pacific Halibut Commission meeting on Monday in Seattle, lead scientist Ian Stewart summarized the outlook for commercial fisheries from Northern California and British Columbia to the Bering Sea.
“In short, the model survey trends as you’ve seen from the previous presentations are down both in numbers and weight per unit of effort. And what we’ve seen from the commercial fishery’s CPUE (catch per unit of effort) is we have mixed trends, however relatively flat at the coast wide levels with some brighter spots and some not so good spots across the coast.”
Northern Fisheries Ltd. of Little Compton, RI, has expanded their voluntary recall of frozen, wild-caught yellowfin Tuna Medallions (product of Vietnam) to include product sold directly to consumers. This recall is due to potentially elevated levels of histamine. Elevated levels of histamines can produce an allergic reaction called scombroid fish poisoning that may result in symptoms that can generally appear within minutes to several hours after eating the affected fish.
Sofly, which has about 50 stores, agreed to start sourcing BAP seafood and to gradually expand the percentage of BAP seafood that it sources to strengthen its commitment to sustainable seafood. Sofly is a regional supermarket chain that focuses on fresh foods.
