Biofuel and salmon feed

A common marine species that consumes microorganisms and can be converted into feed for salmon as well as combustible biofuel for filling petrol tanks.

A common marine species that consumes microorganisms and can be converted into feed for salmon as well as combustible biofuel for filling petrol tanks.

The slimy marine organism can be cultivated in vast amounts (up to 200 kg per square metre of ocean surface area). The research into this species is carried dour by researchers in Norway at the University of Bergen and Uni Research. Tunicates are living filter tubes that suck bacteria and other microorganisms into one end and excrete purified water out the other end. The yellow colored, slimy growth is often seen on ropes that have been lying in seawater.

Norwegian fjords could sustain tunicate farms that produce 100 times more protein by surface area than any land-based protein cultivation. Tunicates grow very quickly and year-round. Found in every ocean, they particularly thrive in cold, nutrient-rich waters such as those around the quays and coastal rock slopes of Western Norway.
