Responding to strong market demand for sea cucumbers in China, Alaska- and Washington-based researchers are developing hatchery and grow-out techniques for the indigenous giant red sea cucumber (Parastichopus californicus).
Farmed salmon contains fewer environmental pollutants than its wild counterpart, according to a Norwegian study that’s been described as the biggest research of its kind so far. The study involved 100 samples of wild salmon caught in the sea in Northern Norway, and 100 samples of farmed salmon.
The demographics and purchasing behaviour of seafood consumers present a host of challenges and opportunities, says Matt Lally, Manager, Analytics and Insight for Nielsen Perishables, a consultancy firm on fresh seafood for the marketplace.
Over the past 14 years, the aquaculture industry has seen a roughly 80-percent decline in the amount of pond space dedicated to catfish, from a peak of around 80,000 hectares in 2002 to about 25,000 hectares in 2016.
The National Oceanic and Atmospheric Administration (NOAA) reached a milestone in May with its first harvest of an all-female generation of mature sablefish. This is a landmark achievement as it makes the farming of this tasty, buttery fish on a commercial scale within the grasp of US fish farmers. The fish harvested weighed an average of 5.47 lbs each, for a total of a whopping 20,227 kgs (roughly 44,593 lbs).
Good news to tilapia aficionados: tilapia has always been good for you. A study showed tilapia’s Omega-6 to Omega-3 (n6:n3) ratios is relatively low compared to normal US diets. This disproves the “worse than bacon” allegation made in 2008 that was based on a study conducted by a research team that exaggerated its interpretation of how tilapia’s n6:n3 ratios were bad for the health.
The permitting process allowing commercial fish farming in the Gulf of Mexico has been in place for a little over a year now but no one has applied for a permit, acknowledged the National Oceanic and Atmospheric Administration (NOAA) recently.
Sea lice have long been a research focus at Fisheries and Oceans Canada's (DFO) St Andrews Biological Station (SABS). Recently, studies have focused on the ecology of their early life history stages, non-chemical methods to reduce their incidence, and genetic selection of sea-lice-resistant Atlantic salmon. These elements have been, or are being studied, in an attempt to combat sea lice outbreaks in near-shore ocean caged fish.
The National Oceanic and Atmospheric Administration (NOAA) is beginning the early stages of work towards opening up federal waters in the Pacific Ocean to aquaculture operations but some are concerned that developing regulations before an industry is established may prevent growth.
As wild fish stocks are being harvested to capacity and global demand for seafood continues to grow, some sectors are espousing that land-based salmon farms are the answer. At present, most land-based farms operate for smolt production. So how economically viable is it to raise salmon on land through harvest size? And what are the implications?
Mike Meeker has been farming rainbow trout off of Manitoulin Island in Canada's Lake Huron since 1984. A self-described "pioneer" in the business, his first net pen was hammered together with logs he cut in the bush and floated on oil drums. He's come a long way since then. As the managing director and part owner of Blue Goose Foods, he oversees two pen sites that each produce a million pounds of trout a year.
The final report published by the Michigan state "Quality of Life" departments concludes an 18-month process, in which the Departments of Agriculture and Rural Development, Environmental Quality, and Natural Resources, considered two applications for net pen trout farming in Lakes Michigan and Huron. (See story in ANA Jan/Feb 2016.)
Alaska, the United States’ top producer of wild seafood, is just in its infancy when it comes to farming it. Current and prospective farmers are looking at the technology and equipment used in Maine, where farming of shellfish and seaweed have been a commercial success for years.
Why not Alaska? That’s a question that Alaska shellfish and seaweed growers are starting to ask themselves. The $6-billion seafood industry in the state produces more seafood than the rest of the US combined. Indeed, if Alaska were a country it would be in the top 10 for seafood production, yet almost all of that comes from the wild fishery.
The livelihoods of oyster farmers in British Columbia, Canada are at risk from a norovirus outbreak that has sickened hundreds in three provinces and forced the closure of nine shellfish farms as of March.
Dynamic and informative industry seminars and speakers, business development networking events, and facility site tours are just some of the reasons to add this event to your busy schedule.
FeedKind protein, a new fish-feed ingredient touted to reduce aquaculture’s use of fishmeal, is expected to reach the market in 2019 once commercial production begins at Calysta Inc’s Tennessee facility.
The US aquaculture industry faces numerous hurdles: a negative image, a difficult regulatory environment and, crucially, a shortage of educated, skilled workers.
As aquaculture continues to produce an increasingly larger portion of seafood consumed in the world, it also becomes a larger and more lucrative market. In recent years that market has attracted the attention of a variety of big grain trading companies that have sought to diversify their products. Companies such as Archer Daniels Midland (ADM), Bunge Ltd and Terra Via shared with Aquaculture North America (ANA) why they wanted to become a part of the aquaculture market.
MSD says it has created a mobile solution for recording data from vaccination controls in the field. AquaVac Audit app allows customers to audit the vaccination event in a format that’s easily analyzed and provides greater insight on areas for improvement. MSD Animal Health’s aquaculture team developed it specifically for MSD customers.
With a jump in speed and improved stability over its predecessor, Inspector 2.0, the recently released robotic submersible developed by California-based SeaDrone Inc, offers fish farmers another way to observe their pens and other underwater facilities without having to get wet themselves.
Israeli startup AquiNovo said “proprietary materials” that can be fed to fish to accelerate their growth will hit the market in 2020.
Aquionics has opened a new sales and service center in Charlotte, NC to meet increasing demand for ultraviolet (UV) disinfection technology in industrial and aquatic applications.
A US-based company specializing in developing barcode traceability and labeling systems has developed a product for the aquaculture industry.
Interest in aquaponics is growing, but the success rate is not exactly stellar. Greener Scenes Aquaponics (GSA) in Brazil, Indiana, is one of the few that has found commercial success. Their journey from small proof-of-concept to commercial success was exciting, to say the least.
Terry Brooks, president of Golden Eagle Aquaculture of Agassiz, British Columbia, says he has the formula to fine-tune coho farming in land-based closed containment systems. “We can do this all day long and provided we don’t outstrip the demand we will be fine,” says Brooks, who got directly involved in the company two years after Golden Eagle acquired the operations from Swift Aquaculture in 2014.
Massachusetts-based biotech company KnipBio has unveiled a fish feed derived from microbes instead of wild-caught fish or agricultural crops.
The first commercial scale indoor Atlantic salmon RAS facility in the US is up and running in Northfield, Wisconsin.
