Cermaq Canada has announced its intention to begin investigating the feasibility of growing its salmon farming operations into Nova Scotia.
Cermaq's farming in Norway takes place north of the Arctic Circle, where the water is cold and the salmon grows slower, resulting in specific product qualities. As consumers increasingly pay more attention to the origin of the food, the Arctic effect represents market value.
Tying salmon farming to the United Nations 2030 Sustainable Development Goals (UN SDG) and selecting the right technology could neutralize biases against farmed salmon, suggests an industry executive.
The big story in catfish aquaculture two years ago was that US farm-raised catfish production was able to meet demand for the first time since 2013. A year prior to that, in 2016, the industry saw annual sales of catfish farmed in the United States reach $386 million, a 7.2-percent growth over the average annual sales during the last five years.
Nordic Aquafarms has announced plans to build a land-based Atlantic salmon farm in California to be close to the regional markets it plans to serve.
According to a peer review conducted by Fisheries and Oceans Canada, farmed salmon that carry and transfer the deadly Piscine Orthoreovirus (PRV) pose a low risk to wild Fraser River sockeye salmon in British Columbia.
The Canadian Federal Court has ruled that juvenile farmed salmon in B.C., must be tested for piscine orthoreovirus (PRV) before being introduced to open net pens.
ARLINGTON, Va. – Nonprofit organizations Conservation International and Ocean Outcomes (O2) are teaming up to create a more sustainable seafood supply chain.
On August 31, Fisheries and Oceans Canada (DFO) released a report on the Live Gene Bank, a program designed to help prevent the extinction of Atlantic salmon in the inner Bay of Fundy. The report confirmed the presence of European farmed salmon genes in the area and touched off a conflict over who to blame for their presence.
Farmed salmon is by far the most important finfish species grown in Canadian aquaculture, accounting for about 90 percent of volume and value of total finfish produced.
The B.C. provincial government and First Nations in the Broughton Archipelago of B.C., have decided to not renew the leases of 17 salmon farms owned by Marine Harvest Canada and Cermaq in the area.
AquaBounty has joined forces with Aquaculture R&D company, The Center for Aquaculture Technologies (CAT), to apply CAT’s patented sterility technology in AquaBounty products.

The decision means AquaBounty will be moving from using triploid induction technology to gene editing to ensure fish sterility.

The two companies signed an agreement whereby both will co-fund CAT’s research which is using gene editing to produce a sterile finfish for use in aquaculture. CAT will hold the patents and AquaBounty will receive a non-exclusive, royalty-free, license to those patents and the technology. The development work will be performed at CAT’s facility in San Diego.

“We are delighted to work with AquaBounty to develop this technology and realize its potential in aquaculture,” Dr. John Buchanan, chief executive officer of CAT.

“Although AquaBounty has been very successful in routinely achieving levels approaching 100 per cent sterility using triploid induction technology, we are very pleased to be working with CAT and using their innovative gene editing approach to ensure 100 per cent sterility genetically,” said Ronald Stotish, chief executive officer of AquaBounty. “Sterility of farmed fish has many environmental and production benefits and we believe this project has a broad range of potential applications in the industry.”

CAT operates two laboratories: its research hub in San Diego, Calif., and the world’s only Level 3 certified pathogen containment, private aquaculture research facility located on Prince Edward Island in Canada. Owing to the expertise of its team and the unique versatility of its labs, CAT is enabling the aquaculture industry to achieve efficient production growth without endangering the natural environment.
When Aquaculture North America (ANA) first asked me why my family got involved in farming seafood on land using recirculating aquaculture systems (RAS) and what potential benefits we saw, I had to take a step back because not only are there multiple levels to the answer, the answer has also been evolving over time as we continue learning about RAS.
Seventy-two percent of the 30 fish processing facilities audited in British Columbia are not compliant with permit conditions and the province says there is a need to strengthen requirements for fish processors in order to protect the marine environment.

The sector-wide audit was conducted after the online publication in November of a video by diver Tavish Campbell that shows fish blood and waste being pumped out of a salmon processing plant in Brown’s Bay near Campbell River.

Results of the audit, released on Wednesday, shows the majority of non-compliances with permit conditions were administrative, such as failing to post signage, but there were a few fish processors that exceeded volumes and the quality of fish processing effluent discharged, than is allowed under their permits.

“This audit clearly tells us more work needs to be done to ensure our coastal waterways are safe for all wild fish stocks,” said George Heyman, Minister of Environment and Climate Change Strategy. “The industry has been largely operating under an outdated permitting regime, going back several decades. We are taking immediate steps to ensure permits are updated and strengthened at fish processing facilities throughout BC.”

The ministry recommends modernizing existing permits to include additional environmental protection provisions, such as more rigorous discharge requirements and increased monitoring, and requiring fish processing facilities to update their update their standard operational procedures to reduce the volume of effluent discharged into the environment.

Salmon and trout producer Cermaq has released its quarterly sustainability results on key indicators related to fish health for the first quarter of 2018.

The company said the key takeaway on sustainability performance from the quarter includes survival rates spanning from 92.5 - 97.3 percent on a 12 month rolling basis, with the highest level achieved for trout in Chile.

In fish health performance, use of antibiotics in Q1 was reduced by 70 percent in Chile compared to the same quarter last year. In Canada, the use was “further reduced” to 9 grams of antibiotics per tonne of salmon harvested within the quarter. The fish harvested by Cermaq Norway in the quarter did not receive any antibiotics, it added.

Average sea lice levels at Cermaq sites worldwide were within regulatory limits, “with the exception of a few sites in Canada where the levels exceeded the regulatory limit and have continued doing so,” said the company. It added that the situation “is being addressed by all available means, including early harvesting and by treatment with hydrogen peroxide.”

Cermaq also reported one incident of escapes in Chile, where 6,284 fish, weighing 2.9 kg each on average, escaped its operations due to ripped nets.

The company started publishing quarterly sustainability results in early 2016.
