10/10/13: Brazilian macroalgae, Hawaiian tuna farms and pick your poisson


Hawaii Business magazine reports on Syd Kraul, a Kona aquaculturist aiming to raise the world’s first farm-raised yellowfin tuna. The premium fish, also known as ahi, reach maturity at a relatively small size, giving them a competitive advantage over the bluefin tuna which currently dominate the sushi scene.

Northeastern Brazil is following Rio de Janeiro’s example in developing a macroalgae farming programme for its coastline. Around US$3.6 worth of federal funds will be invested in Alagoas, Brazil’s second-smallest state. Aside from creating jobs and usable seaweed products, the project will also help keep algae blooms out of local landfills.

And finally, Norwegian fish institute Nofima has provided a solution to the age-old problem of getting your brats to eat fish. A study in June took 130 school pupils out to dinner: half were given a choice between salmon and cod, and half were just served one or the other, no questions asked.  Scientists found that the children given the chance to pick their poisson enjoyed their meal a lot more.
