Iowa State University researchers make fish food from Iowa agricultural commodities

Researchers at Iowa State University are charting new waters by turning the state’s agricultural commodities into fish food, work that could help farmers find new revenue streams and provide a boost to U.S. fish production. Kurt Rosentrater, an assistant professor of agricultural and biosystems engineering, is studying how food derived from corn and soy can be…

Fewer Wild Fish Needed: Genetically Modified Plants Produce Omega-3 Fish Oil

Researchers have revealed that genetically modified Camelina plants produce omega-3 fish oils suitable for feeding Atlantic salmon. The new GMO plants can produce up to 20% of eicosapentaenoic acid (EPA), one of the two omega-3 LC PUFA conferring health benefits. Consumption of omega-3 fish oils, specifically long-chain polyunsaturated fatty acids (omega-3 LC-PUFA), through eating oily fish like salmon…

Norwegian sea lice report provide transparency

Salmon lice (Lepeophtheirus salmonis) infestation was first registered at the end of the 1980s in Ireland when it was found that sea trout returned to Irish rivers and fresh water to dispose of the salmon lice. One year later the same behavior was detected in sea trout in Norway. The largest salmon farming nation, Norway, has…

New SFI on closed fish farming facilities

Uni Research, together with Nofima and UiB, will create a Centre for Research-based Innovation (SFI) on closed-containment systems for salmon aquaculture. The center will be named CtrlAQUA, Centre for Research-based Innovations in Controlled-environment Aquaculture. The creation of the SFI is in collaboration with 14 companies from aquaculture and supplier industries. The aim, as described in the…

Nofima to host Centre for Research-based Innovation

Nofima is one of 17 institutions chosen recently to become hosts for Centres for Research-based Innovation (SFI). The centre is to contribute to solving some of the main challenges facing the aquaculture industry, such as lice and mortality. It is to lay the foundation for the development of closed-containment concepts of the future. With greater…

Technological advances can offset resource constraints, FAO experts say in new study

Fish farming will likely grow more than expected in the coming decade, offering a chance for improved nutrition for millions of people, especially in Asia and Africa, according to a new report. Increased investment in the aquaculture sector – particularly in productivity-enhancing technologies including in the areas of water use, breeding, hatchery practices and feedstuff…

Development of sterile fish using an immunization approach

Aquaculture have become an important industry in Norway, and in 2010 more than 1 million tons of farmed salmon and trout were produced. However, Norway has, through international agreements, a special obligation to preserve wild Atlantic salmon populations. There is consensus among researchers that excessive crossing with escaped farmed salmon could be detrimental to the…

Escape proof cage net concept from Aqualine

The Aqualine Midgard System is the result of several years of determined work to find new and better solution within cage net technology, such as floating collar, sinker tube and net. The new total cage solution, Aqualine Midgard System, consists of the following new elements: Newly designed fish farming net where the sinker tube is…

Making fish food from captured carbon Mongstad pilot will grow omega-3-rich algae

A new pilot project at Norway’s Technology Centre Mongstad (TCM) will use captured CO2 to grow omega-3 fatty acid-rich algae for fish feed. The Norwegian aquaculture industry is worth US$10.2 billion/y to the Norwegian economy, and as demand for fish grows, so too does the demand for fish feed. Omega-3 fatty acids are essential for fish growth and are added to feed. These are usually obtained from small oily fish, but stocks…

Brazil and Norway Expand Cooperation in Aquaculture Development

   Brazil and Norway have continued the identification of areas for Technical Bilateral cooperation in order to develop and improve aquaculture in both countries. Identifying these areas occurred during the Nor-Fishing trade show in Trondheim, Norway, with the presence of the Queen of Norway, the Minister Eduardo Lopes and Secretary of Planning and Land Aquaculture…
