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…

Is genetic advancement the answer to feeding the world?

Global agricultural food production relies on the benefits gained from many generations of selective breeding, and the vegetables, cereals and livestock we eat today are vastly more productive than the wild species our distant ancestors first domesticated. Similar benefits are beginning to become apparent in the field of aquaculture, where recent advances in production techniques,…
