Genes for de novo biosynthesis of omega-3 polyunsaturated fatty acids are widespread in animals

 Marine ecosystems are responsible for virtually all production of omega-3 (ω3) long-chain polyunsaturated fatty acids (PUFA), which are essential nutrients for vertebrates. Current consensus is that marine microbes account for this production, given their possession of key enzymes including methyl-end (or “ωx”) desaturases. ωx desaturases have also been described in a small number of invertebrate…

UC Santa Barbara study says farming fish saves land

To satisfy the protein demands of an anticipated nearly 10 billion people by 2050, the United Nations’ Food and Agriculture Organization (FAO) and researchers around the world estimate current animal production will need to grow by an average of 52 percent. Meeting this need without pushing the environment to the brink will be critical. New…

Timberfish turns booze into food – fish food

Out on farmland in western New York, near the shore of Lake Erie, is Five & 20 Spirits and Brewing. Here, they make more than just booze. They also raise fish. Inside a large white structure set back behind the brewery is a land-based aquaculture system. It’s the life’s work of Jere Northrop, founder of…

SalMar creates aquaculture professorship

The salmon farming giant SalMar is working with Norway’s University of Science and Technology (NTNU) to create a new professorship in the field of aquaculture. The project is being driven by the huge technological surge within the industry which both the company and the university believe will lead to major changes in how the sector…

GEN-innOva® GAIN – Start material with increased potential for lice resistance, handling tolerance and growth

The battle against salmon lice can only be won by using a combination of preventative and treatment methods. Breeding and genetics is one of the few methods that increase the fish’s resistance against lice throughout the whole production cycle. Reduced risk of lice infection, robust fish that tolerate handling and a short production time in…

Sea the possibilities: to fight climate change, put seaweed in the mix

The next stage of humanity’s fight to reduce greenhouse emissions may revolve around seaweed, according to tonight’s episode of ABC’s Catalyst, presented by Professor Tim Flannery, which asks the question “can seaweed save the world?” With the help of me and colleagues around the world, the documentary explores seaweed’s enormous potential to reduce greenhouse gases…

Can We Feed The World With Farmed Fish?

For years, scientists and activists have sounded the alarm that humans’ appetite for seafood is outpacing what fishermen can sustainably catch. But new research suggests there is space on the open ocean for farming essentially all the seafood humans can eat. A team of scientists led by Rebecca Gentry, of the University of California, Santa…

Blue cod

Scientists manage to breed blue cod in captivity

For the first time, a team of scientists has succeeded in breeding blue cod in captivity, an achievement that would help to boost the aquaculture sector in New Zealand. These researchers, of the Seafood Technologies team at Plant and Food Research, have managed to farm blue cod to fingerlings, in association with Ngāi Tahu Seafood…

NOAA intends to develop commercial sablefish farming

Scientists from the National Oceanic and Atmospheric Administration (NOAA) intend to find ways to make it easier and more efficient to commercially harvest sablefish (Anoplopoma fimbria) as part of the federal agency’s efforts for marine aquaculture to contribute to meet a growing demand worldwide for seafood. Sablefish, also known as black cod or butterfish, are…
